Hello,
I have a treeview which I'm styling as such (and it works fine):
<Style x:Key="GenericTreeViewStyle" TargetType="{x:Type TreeView}">
<Setter Property="BorderBrush" Value="{StaticResource ListBorder}"/>
</Style>
....
<TreeView Name="myTreeView" Style="{StaticResource GenericTreeViewStyle}" >
<TreeView.Resources>
<LinearGradientBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="Blue" Offset="0"/>
<GradientStop Color="DarkBlue" Offset="1"/>
</LinearGradientBrush>
<LinearGradientBrush x:Key="{x:Static SystemColors.ControlBrushKey}" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="DarkGreen" Offset="0"/>
<GradientStop Color="Green" Offset="1"/>
</LinearGradientBrush>
<!-- Text in the TreeViewItem for when it's selected and focused -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="White" />
<!-- Text in the TreeViewItem for all other cases -->
<SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="Red" />
</TreeView.Resources>
</TreeView>
I'd like to make this a generic style that all instances of treeviews can pick up. So, I'd like to move everything from the TreeView.Resources chunk to GenericTreeViewStyle (or whatever other place necessary to achieve my goal). All my attempts have failed so far so I must be missing something. Appreciate your guidance please!

Hi
I'm raw when it comes to using WPF and c# so forgive me if I'm asking a basic question.<o:p></o:p>
I have a Stackpanel with a Listbox and a set of Textblocks which are bound together. The Listbox gets its values from an xml file. The bindings work great. My problem is I want the result of changing the Listbox to be saved back to the source xml file and I'm unsure how to do this. I've hunted high and low and can't find anything to guide me.
I've a button that I want to use to update the source file testxml.xml but I'm unable to code the click event to perform the update.
How do I code the UpdateButton_Click so that the source gets updated from the Listbox? Any help much appreciated.
Key components of my xml coding are:
<StackPanel.Resources><XmlDataProviderx:Key="xmlFeed"Source="c:\users\brian\desktop\testxml.xml"XPath="Greens/item"/></StackPanel.Resources> ... <ListBoxName="entryListBox"Height="300"Width="200"ItemsSource="{Binding Source={StaticResource xmlFeed}, XPath=//Greens/item}"IsSynchronizedWithCurrentItem="True"Visibility="Visible"SelectionMode="Single"><ListBox.ItemTemplate><DataTemplate><TextBlockText="{Binding XPath=title}"/></DataTemplate></ListBox.ItemTemplate></ListBox>
<TextBlockGrid.Row="0"Grid.Column="0">Title</TextBlock><TextBoxGrid.Row="0"Grid.Column="1"Name="titleText"Text="{Binding XPath=title}"/><TextBlockGrid.Row="1"Grid.Column="0">URL</TextBlock><TextBoxGrid.Row="1"Grid.Column="1"Name="urlText"Text="{Binding XPath=guid}"/><TextBlockGrid.Row="2"Grid.Column="0">Date</TextBlock><TextBoxGrid.Row="2"Grid.Column="1"Name="dateText"Text="{Binding XPath=pubDate}"/><TextBlockGrid.Row="3"Grid.Column="0">Body</TextBlock><TextBoxGrid.Row="3"Grid.Column="1"Name="bodyText"TextWrapping="Wrap"Text="{Binding XPath=description}"/><ButtonGrid.Row="4"Grid.ColumnSpan="2"Grid.Column="0"Click="updateButton_Click"> Update</Button>

I'm trying to make a Master/Detail relationship between a ComboBox and a DataGrid.
In my DataSet I have 2 tables and a Relation between the two.
I set the DataContext of my Window in XAML to a ViewModel class.
I set the ItemsSource of the ComboBox to a BindingListCollectionView (ItemsSource="{Binding TheBLCV}").
I can get the DataGrid to correctly display the rows corresponding to the selection in the ComboBox if I set the DataGrid's ItemsSource in code behind with this:
Binding bnd;
bnd = new Binding("TheRelation");
bnd.Source = TheBLCV;
TheDataGrid.SetBinding(.....ItemsSourceProperty, bnd);Michael
Hi, using Visual C# 2010 Express, in WPF datagrid I have SelectionUnit="CellOrRowHeader"
The datagrid is populated by a datatable from a database query
Now,
1) when the user selects any cell in the datagrid I want to read certain cells on the same row as the selected cell
Let's say, if cell [row=5, col=2] is selected I want to now get values in cell [row=5, col=1]
How can I do this?
2) When I select any Cell, why is the grid SelectedIndex always '-1' ?
In traditional winforms datagridview, selecting any cell would make the corresponding row the Current Row
How to make the row of a selected cell the Current Row in WPF?
I don't want to change SelectionUnit="CellOrRowHeader" because I want to let users select specific cell so they can copy the contents of that cell only
Also, is there an easy way to show the current row indicator in WPF datagrid (like the triangle in row header in winforms datagridview)?
Thanks,

I have a DataGrid with two columns (Name and Status). The Status column is an unbound column with checkboxes. I'm am trying to obtain the Names (In a String) in the first column with the corresponding Checkboxes that are checked in the second column.
Any suggestions? Thanks
Hello,
I'm building a Portable Class Library that wraps a WCF Service Reference and targets .NET 4.5, Windows Store, Windows Phone.
I have hit somewhat of a roadblock, the generated proxy classes are using the async pattern <MethodName>Async(...) methods and <MethodName>Completed(...) events. While it is claimed that the exception will be forwarded to the Completed event should an error happen this is simply not the case. During debugging or running without the debugger the exception is classed as unhandled and pops out of the generated EndXxx( ) method thus I cannot catch the exceptions and forward them to the client application (to display an appropriate message and continue execution).
The Completed event is not triggered until after the exception shows up in the debugger as unhandled. What can I do to catch the exceptions in my Portable Class Library so that I might handle them properly? Is there something I'm missing?
Thank you!
Here's a cut down version of the code that makes a call to the WCF service client that I expect to throw an exception (for testing purposes).
public static Task<T> TryOperationAsync<TClient, T>(TClient client, Func<TClient, T> operation)
where TClient : class, ICommunicationObject
{
return Task.Factory.StartNew(( ) =>
{
try
{
T result = operation.Invoke(client);
client.Close( );
return result;
}
catch (Exception ex)
{
client.Abort( );
throw ex;
}
return default(T);
});
}
public async Task<IEnumerable<DataObject>> LoadDataAsync( )
{
return await SharedServiceHelper.TryOperationAsync(serviceClient, client =>
{
ManualResetEvent waitHandle = new ManualResetEvent(false);
Exception error = null;
client.GetDataCompleted += (sender, e) =>
{
error = e.Error;
try { cache = e.Result; } catch { }
((ManualResetEvent)e.UserState).Set( );
};
// block this operation until the completed event is fired..
// this effectively the same as calling await SomeOperationAsync(...)
waitHandle.Reset( );
client.GetDataAsync(waitHandle);
waitHandle.WaitOne( );
if (error != null) throw error;
return clientCache;
});
}Someone posted almost the exact same question here. I attempted to use that answer in my situation but am not sure how to form the syntax. I'm using WPF and EF.
I, too, have a master/detail situation that uses a combo box that fills a datagrid. The combo is sorted by patient name. I'd like the grid to sort by appointment date.
The EF wizard created the following code (I added the sort description).
Dim TblPatientDemographicViewSource As System.Windows.Data.CollectionViewSource =
CType(Me.FindResource("TblPatientDemographicViewSource"), System.Windows.Data.CollectionViewSource)
'sort view by patient name.
TblPatientDemographicViewSource.SortDescriptions.Add(New SortDescription("PatientName", ListSortDirection.Ascending))
'Load data by setting the CollectionViewSource.Source property:
'TblPatientDemographicViewSource.Source = [generic data source]
_context.tblPatientDemographics.Load()
TblPatientDemographicViewSource.Source = _context.tblPatientDemographics.LocalThe suggested answer (converted to vb.net from c#):
DirectCast(TblDentistAppointmentsDataGrid.Items, ItemCollection).SortDescriptions.Add(New System.ComponentModel.SortDescription("DentistAppointmentDate", System.ComponentModel.ListSortDirection.Ascending))I'm not sure where to place this suggested code in my code block. More importantly, I'm not sure the syntax is correct. Looking at the xaml, I noticed the resource name:
<DataGrid x:Name="TblDentistAppointmentsDataGrid" AutoGenerateColumns="False" EnableRowVirtualization="True"
ItemsSource="{Binding Source={StaticResource TblPatientDemographictblDentistAppointmentsViewSource}}"
I thought maybe that resource is what I should apply the sort description to but that is not an option when forming the syntax. Thanks.
Hi all,
I ran across a problem where I'm drawing lines and text blocks on a canvas. When I save the canvas using the XAMLWriter, the lines show up but not the text blocks. I'm opening the XAML file in Inkscape. Some example code below shows what I'm trying to illustrate.
