When I unchecked the Green check box option and click the "Set item to red" button, it able from "No Error" UI change to display tree nodes.

However, if I try to repeat those steps, unchecked green check box and call the methods without click the button, it unable to change the UI from "No Error" to display tree nodes.

I have try to mock the situation by implement this

//start test
            Thread t = new Thread(() => {
                Thread.Sleep(10000);
                List<uint> DataNotificationList = new List<uint>()
            {
                2,
                6,
                9
            };

                foreach (uint studentId in DataNotificationList)
                {
                    foreach (var course in treeListViewModel.Courses)
                    {
                        Student student;

                        if (course.Students.TryGetValue(studentId, out student))
                        {
                            student.ExecuteStrategy(hasError());
                            break;
                        }
                    }

Hi,

I have written the following for retrieving the datagrid selecteditems, which is a readonly property .

namespace Wpf.Behaviours
{
    using System.Collections;
    using System.Windows;
    using System.Windows.Controls;

    public static class DataGridSelectedItems
    {

        public static readonly DependencyProperty SelectedItemsProperty = DependencyProperty.RegisterAttached("SelectedItems", typeof(IList), typeof(DataGridSelectedItems), new PropertyMetadata(OnSelectionChanged));

      
        #region SelectedItems

        public static void SetSelectedItems(DependencyObject frameworkElement, IList value)
        {
            frameworkElement.SetValue(SelectedItemsProperty, value);
        }

        public static IList GetSelectedItems(DependencyObject frameworkElement)
        {
            return (IList)frameworkElement.GetValue(SelectedItemsProperty);
        }

        #endregion

        private static void OnSelectionChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs e)
        {
            var datagrid = (DataGrid)dependencyObject;

            if ((bool)e.NewValue)
            {
                datagrid.SelectionChanged += new SelectionChangedEventHandler(datagrid_SelectionChanged);
            }
            else
            {
                datagrid.SelectionChanged -= datagrid_SelectionChanged;
            }
        }

        private static void datagrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            var datagrid = sender as DataGrid;
            UpdateSelection(datagrid);
        }

        private static void UpdateSelection(DataGrid datagrid)
        {
            if (datagrid != null)
            {
                datagrid.SetCurrentValue(SelectedItemsProperty, datagrid.SelectedItems);
            }
        }
    }
}

Binding in xaml is as follows

<Datagrid 

Behaviours:DataGridSelectedItems.SelectedItems="{Binding SelectedItems, Mode=OneWayToSource}"/>

The selecteditems property setter is being called only once and that too on startup, its not getting called on selection change. May someone help me by correcting my code.

Thanking you

Hello,

I need to interate over the segments of a PathSegmentCollection.

However, I do not know what type of segment types the collection will have, so I must to test the type for each one and make the apropriated processing.

How can I "switch" over all possible PathSegment derived object types?

Here they are:

Hi,

I want to handle various keys on my key down event for a textbox.

So the scenario is that i have a textbox and therein if all the text is selected, i can press the Del or Back keys and the text gets deleted. I can even press numeric and alphabets keys and the same thing should happen.

I cannot press Modifiers Keys viz. Ctrl,Alt,Shift,Shift-Tab,etc.... Also the up and down arrow keys.

Is there any efficient and a minimal way to handle this or i will have to write the code for checking each and every key by using e.key ??

Thanks,

Abdi

During a long research of this topic it seems as if not many developers are concerned with this. Latest .NET does not have it implemented, I have not found a commercial solution except one from Telerik and regarding open source versions:

The best solutions I have found are from Bea Stollnitz
http://bea.stollnitz.com/blog/?p=344
and from  Weifen Luo
https://datavirtualization.codeplex.com/

but latest version is from April 2010, with same problems of selection and sorting. Reading the number of downloads I don't even need to ask if you are using this. Do you have a need for data virtualization and what are you using for this? There must be something newer and better after more than 4.5 years.

Hi,

I want to implement context menu for DataGridColumnHeader with just one menu item "Remove Column". The menu item name is self explanatory i.e. using this context menu Item, I want to remove the DataGridColumn from the Grid. How this can be achieved in WPF way?

I have following xaml code for creating context menu.

<ContextMenu x:Key="headerContextMenu"><MenuItem Header="Remove Column" Click="item_Click"/></ContextMenu><Style TargetType="DataGridColumnHeader"><Setter Property="ContextMenu" Value="{StaticResource headerContextMenu}"/></Style>

What I'm not able to figure out is what code I should write to remove the datagrid column? I cannot get reference of datagridcolumnheader/datagridcolumn inside menu item click event and also Visual tree of Context Menu and DataGrid are different.

Hi,

I have a class library and I'm trying to bring in a test key value, but it's returning null and I can't seem to get it working.

string returnValue = ConfigurationManager.AppSettings["testkey"];

<?xml version="1.0" encoding="utf-8" ?><configuration><appsettings><add key="testkey" value="testvalue"/></appsettings></configuration>

Hi everyone,

I have two list controls which are placed in a grid in two adjacent columns.

The second list may or may not have items. If it doesn't then it's visibility is collapsed so that the first list can occupy the whole space.

This is the code:

<Grid><Grid.ColumnDefinitions><ColumnDefinition Width="*"/><ColumnDefinition Width="Auto"/><ListBox
                         HorizontalAlignment="Stretch"
                         Grid.Column="0"
                         DockPanel.Dock="Top"
                         FontSize="10pt"
                     ScrollViewer.VerticalScrollBarVisibility="Auto"
                         /><ListBox
                             Grid.Column="1" HorizontalAlignment="Right"
 Visibility = "{Binding Path=HasItems,
RelativeSource={RelativeSource Self},
                             Converter={StaticResource BoolToVisibilityConverter}}"

                             /></Grid>

But I can see the second list space still present when I run the application. That is even though there are no items in the second list, the first list still doesnt occupy the whole space. But if I some how refresh that space, by loading some other data in that list etc I can see it works as expected.

It doesnt work first time when I run the application.

Thank you.

Hi,

I would like to bind data from an XmlDataProvider to a datagrid.

I've got an xml data like this bellow and I would like to bind a datagridcomboboxcolum to list all vendors - Surname for a given project(Datagrid context is already binded to combobox that selects a project).

<?xml version="1.0" encoding="utf-8" ?><ProjectList><SingleProject id="1" name="TRP"><LanguageList><Language id ="1"><TargetCode>en-gb</TargetCode><TargetLanguageName>English</TargetLanguageName><VendorList><Vendor id="1"><Name>Karin</Name><Surname>AAA</Surname><GridPath>e:\stuff</GridPath></Vendor><Vendor id="2"><Name>Kate</Name><Surname>BBB</Surname><GridPath>e:\stuffss</GridPath></Vendor></VendorList></Language></LanguageList></SingleProject></ProjectList>

                                            DisplayMemberPath="{Binding XPath=*}"/></DataGrid.Columns></DataGrid></Grid></UserControl>

I have a problem with binding DataGridComboBoxColumn "dcbVendorList" to list all vendors from an xml. Combobox should have a Surname displayed as an item.

Then based on the selection from a dcbVendorList, datagridtextcolumn "dtcVendorName" and "dtcVendorSurname" should be filled with data from this combobox.

I've tried to use Xpath * and . with no luck. It seems that a current item is "Language" xml node from a datacontext.

<DataGridComboBoxColumn x:name="dcbVendorList" Header="Default Vendor" DisplayMemberPath="{Binding XPath=*}

Any help is greatly appreciated.

I don't want to set DisplayName="This is a Book".

Hi,

I get a 'This Freezable cannot be frozen' exception each time a user logs in remotely to the app and then logs in locally.

It is thrown as domain exception so no way to avoid the app crashing.

There are no Freeze() calls in our application so it must be something with the resources.

What can be causing it? Any ideas? I have read many articles on Freezables online but found no hints on how to solve this particular case.

Regards,

Tomasz

Hi to all,

I have a combobox with values from DataContext. the 1 field is byte[] values.

how can I show them in my combobox?

thanks in advance 

PubCB.DataContext= myDatatable

            </ComboBox.ItemTemplate>
        </ComboBox>

I have a UserControl, where I get the information of some elements using VisualTreeHelper class. But when I change the data and want to apply it to the same control (element), it doesn't update. Is there any way that I could update the xaml from the code behind? 

            Path arc1 = null,cap1 = null, cap2 = null;
            Path[] paths;
            paths = FindVisualChildren<Path>(userC).ToArray();
            arc1 = paths[0];
            cap1 = paths[1];
            cap2 = paths[2];


                    PathFigure pf = new PathFigure();
                    pf.StartPoint = new Point(0, h);
                    pf.Segments.Add(new ArcSegment(new Point(w, h), size, 0, false, SweepDirection.Clockwise, true));
                    PathGeometry pg = new PathGeometry();
                    pg.Figures.Add(pf);
                     arc1.Data = pg; //obvious it'll not update here because it just copied the information to another
		    // Path. But how can I update it? 

HI,

 I have canvas in Xaml with MouseLeftButtonDown event for panning control, and path in Xaml.cs for Brush it randomly. Here Path is bounded between canvas ("CanvasPanel.Children.Add(path);"). Now when I use to move using MouseLeftButtonDown event, it is triggering both events of Path and Canvas. I want 2 events trigger differently so that when I use for panning it shouldn't fill color in Path which is bounded between Canvas. I Don't want to fill Path with color when I do Panning for canvas.

Here is the link for Source code:

Please Help me.

I can't figure out what is going wrong for this corner case. Basically, I have a DataGrid that is bound to an ObservableCollection in my view model. The SelectedItem of the DataGrid is also bound to a property in my view model. I then have a command that executes a delete operation on the selected item. I have also added an event handler for CollectionChanged so that I can be notified when an item has been removed from collection. In that event handler I update the selected item property to the item at the same index (or previous index if it was the last item). I do this in the collection changed event handler because the collection gets updated from a variety of places and want the selection to be managed from this one place.

The problem is that when I select the second to last item and delete it, the selected item is updated to the last item (since that item was shifted down into that index). But the DataGrid highlighting is not updated to that row. If I turn row headers on, I can see the row header is highlighted, but the row is not. The highlighting works fine if I delete any other item in the list, including the last item.

I created a small app that reproduces this (excuse the sloppy MVVM as I threw this together for demo only).

XAML:

<DockPanel><Button DockPanel.Dock="Bottom" Content="Remove" Command="{Binding DeleteCommand}" CommandParameter="{Binding}"  /><DataGrid DockPanel.Dock="Top" ItemsSource="{Binding People}" SelectedItem="{Binding SelectedPerson, Mode=TwoWay}"><DataGrid.RowStyle><Style><Style.Resources><!--Forces the selection color to be the system highlight color when the item does not have focus--><SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{x:Static SystemColors.HighlightColor}" /></Style.Resources></Style></DataGrid.RowStyle></DataGrid></DockPanel>

ViewModel:

    public class ViewModel : INotifyPropertyChanged
	{
		public ViewModel()
		{
			People = new ObservableCollection<Person> { new Person("Jack"), new Person("Jill"), new Person("Jon"), new Person("Jane"), new Person("Joe") };
			People.CollectionChanged += PeopleOnCollectionChanged;
		}

		private ObservableCollection<Person> mPeople;
		public ObservableCollection<Person> People
		{
			get { return mPeople; }
			set
			{
				if (mPeople != value)
				{
					mPeople = value;
					OnPropertyChanged("People");
				}
			}
		}

		private Person mSelectedPerson;
		public Person SelectedPerson
		{
			get { return mSelectedPerson; }
			set
			{
				if (mSelectedPerson != value)
				{
					mSelectedPerson = value;
					OnPropertyChanged("SelectedPerson");
				}
			}
		}

		private DeleteCommand mDeleteCommand;
		public DeleteCommand DeleteCommand
		{
			get { return mDeleteCommand ?? (mDeleteCommand = new DeleteCommand()); }
		}

		private void PeopleOnCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
		{
			if (e.Action == NotifyCollectionChangedAction.Remove)
			{
				SelectedPerson = People.Count == 0 ? null : e.OldStartingIndex < People.Count ? People[e.OldStartingIndex] : People.Last();
			}
		}

		public event PropertyChangedEventHandler PropertyChanged;

		[NotifyPropertyChangedInvocator]
		protected virtual void OnPropertyChanged(string propertyName)
		{
			PropertyChangedEventHandler handler = PropertyChanged;
			if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
		}
	}


	public class Person
	{
		public string Name { get; set; }

		public Person(string name)
		{
			Name = name;
		}
	}

	public class DeleteCommand : ICommand
	{
		public void Execute(object parameter)
		{
			ViewModel viewModel = ((ViewModel) parameter);
			viewModel.People.Remove(viewModel.SelectedPerson);
		}

		public bool CanExecute(object parameter)
		{
			ViewModel viewModel = ((ViewModel)parameter);
			if (viewModel == null) return false;
			return viewModel.People.Count > 0 && viewModel.SelectedPerson != null;
		}

		public event EventHandler CanExecuteChanged
		{
			add { CommandManager.RequerySuggested += value; }
			remove { CommandManager.RequerySuggested -= value; }

Hi.  I have a Windows Form application in VB 2013 with a Document Viewer control which I am using to display XPS documents. 

Most of the documents I want to display here are reports from a legacy system which were designed to be in landscape format  The XPS documents were created either by printing text reports to the XPS Document Writer printer or by printing PDF reports to the XPS Document Writer printer. In both cases the orientation was set to Landscape and I want to be able to display and print them this way. 

When they are displayed in the Document Viewer control, the text runs sideways.  I believe this is because the pages are oriented this way after "printing" them to XPS.  In other words, they are in landscape format, with the text running parallel to the long edge of the page, but the pages themselves are orientated in portrait.   I would like to be able to convert these documents into documents which have the pages themselves oriented in landscape.  I have tried a number of things, including a MatrixTransform, but have not been able to get this to work.

Does anyone have any suggestions/examples of how to do this? 

Thanks.Mary
