Hi All,

I have the following code, wich displays a listbox, that is dynamically populated in the code behind. So the amount of items may vary. I would like each entry in the listbox (each set of label + combobox || label + textbox), to become a tabstop. Currently only the first item is a tab stop, and then when I press tab again, the first text box or combo (that is WITHIN the list) becomes tab stop. 

Alternatively if this is not possible, I want the input mechanisms should become tab stops, such as the combo and the text....

Here is code behind:

I created a UserControl with TextBlock, TextBox and ComboBox

I have MainWindow with TabControl and this tabcontrol has several UserControls, one UserControl per TabItem

The UserControls in TabItems have the custom UserContol that I created.

Everything is working fine except the ComboBox, the ComboBox fills with data items and SelectedValue, but when I switch tabs on the MainWindow the Property that's bond to the SelectedValue gets set to null value and I can not figure out what is passing the null value, I put a break point inside the ComboBox SelectedValue setter property and the value shows null when the program hits the break point, but when I try to continue stepping through the code the code exits the Set portion of the property and goes to the Get portion, it does that twice and then goes to the next Object so I can't figure out what is passing the null value.  The SelectedValue gets correct value when I open the program, but gets nulls when I switch tabs.

I am new to WPF so I am not sure what I am doing.

I know it's probably impossible to tell what is causing this without seeing the entire program, but maybe someone had similar issue and has an advice on how to trouble shoot this or at least some suggestion on how to create an UserControl.

Here's the XAML to my custom UserControl

            <ColumnDefinition Width="*"></ColumnDefinition>
            <ColumnDefinition Width="100"></ColumnDefinition>

        </ComboBox>
    </Grid>
</UserControl>

Here's code for the custom UserControl

Same code is working on my old machine with same visual studio 2008 but on my new machine it is not displaying it at all.

Please suggest me some solution to resolve this issue as soon as possible.

Hello,

How to get barcode reader value in TextBox.

Hi,

I am using the LiveGrouping feature of CollectionViewSource. It is working as I expected but I need to know when the View has been refreshed with new group data. I can't find any event that will indicate this. The Groups property of the CVS is a ReadOnlyObservableCollection and does not have a CollectionChanged event associated with it.

Any ideas?

Thanks

I'm trying to create a control that derives from TabItem. It works fine at run-time, but when I view it in the designer, all I see is the header. The TabItem is in its own file (like a UserControl). It happens in both VS and Blend.

What do I need to do so I see the content of the TabItem in design view?

Thanks for your help!

I have a WPF Grid, a Combo Box and check box fields as items of the combo box. Combobox items are the grid headers/columns. Currently, the ComboBox is binded to the columns of the Grid and Grid header is toggeled based on the toggling of the checkbox items of Combobox.

Now, I have to change this behaviour so that only some fileds are visible on the grid and those which are not visible are availabe in the Combobox as non-selected items with the fields that are visible on the grid as selected items. Toggling the checkbox items in the combobox would toggle the grid header/column visibility. Please suggest.

 Hi,

  Is there any control in wpf that support databinding with repeated column headers to display in flow document.

   currently iam using   Document.Table .It more flexible in flow document .but it does not support binding like we have in grid/Listview. if we are using grid in flow document say the grid has 100 row these rows will only fit with the height of grid with scroll option.so i need a control that fulfills data-binding with repeated column headers for  overflow to another-page. can u please go through my project on https://skydrive.live.com/?cid=96FB4F1E3660C28B&id=96FB4F1E3660C28B!103

Hallo, I have a WPF .net 4.5.1 Application for clickonce deployment on Windows 8.1 machines. Unfortunately the feature "File Association" does not work. 

- I made my application offline

- Added the File Association over Visualstudio (Project-->Properties-->Publish-->Options-->File Association)

Does anyone have an idea? Thanks for help in advance.

Hi Team,

We are preparing one desktop WPF based form application for which we are implementing system tray functionality. The problem first is with "Alt + F4" and close from task bar where user can right click the application and choose close.

Other operations from UI where user can minimize or click cross button I am able to capture and enter the application in system tray. Can anyone suggest how to capture "Alt+F4" and close from task manager.

Also one problem like when application is in system tray and not on task bar, I am not able to get its Process.MainWindowHandle value, which i read is not possible when the application is only in system tray and not on task manager. How can this be done.

Thanks,

Nikhil.

I have a tab control with two tab items situated on 3/4 of a wpf page. Each tab item has a number of buttons, combo boxes etc.

If I select the tab items (flick back and forth a couple of times), and then click on a button outside the tab control, the tab control selection changed event fires and the previous selected tab item is displayed. The impression I get is that the button click event is trying to close the tab item. How do i trap this.?

its somewhat similar to the tabcontrol behaviour described in this thread.

regards.

Hi,

I have created a custom control eg QuanityCustomControl which inherits from the textbox control and have defined a DP called quantity, and need to bind this Quantity Property to the Text Property of the control.  I get an xaml parser error than binding can be done only on Dependency Property of Dependency Object. I know that Quantity is a DP, and Text is also a DP. Its a silly and small issue. 

this is the code of the custom control

 public class QuantityCustomControl : TextBox
    {

        public string Quantity
        {
            get { return (string)GetValue(QuantityProperty); }
            set { SetValue(QuantityProperty, value); }
        }

        // Using a DependencyProperty as the backing store for MyProperty.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty QuantityProperty =
            DependencyProperty.Register("QuantityProperty", typeof(string), typeof(QuantityCustomControl), new PropertyMetadata("0",QuantityChangedCallback));

        private static void QuantityChangedCallback(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            if (!Regex.IsMatch
            ((string)d.GetValue(e.Property), @"^[0-9]"))
            {
                d.SetValue(e.Property, "000-00-0000");
            } 

        }

    }

and this is the xaml where it is used. 

<cc:QuantityCustomControl Width="100" x:Name="ccc"  Height="25" Quantity="{Binding RelativeSource={RelativeSource Self},Path=Text}" ></cc:QuantityCustomControl>

It throws an error as mentioned in the title.

Hi there,

this days I get a strange clipping issue with .NET 4.0, perhaps it will occur also with other Versions. I drilled it back to a simple border with a rectangle inside. The same behaviour you can get with other controls, i.e. the buildin arrow controls.

If I take this elements at two different y-positions one element will be clipped the other not. If I Change the y-Position the behaviour will change.

See my code here:

<Window
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	x:Class="WpfClipError.MainWindow"
	x:Name="Window"
	Title="MainWindow"
	Width="640" Height="480"><Grid x:Name="LayoutRoot"><Border x:Name="NotClipped" Margin="360,0,0,160" HorizontalAlignment="Left" Width="80" Height="24" VerticalAlignment="Bottom" BorderBrush="Black" BorderThickness="2"><Rectangle Margin="-9,0,0,0" Fill="red" /></Border><Border x:Name="Clipped" Margin="360,0,0,115.329" HorizontalAlignment="Left" Width="80" Height="24" VerticalAlignment="Bottom" BorderBrush="Black" BorderThickness="2"><Rectangle Margin="-9,0,0,0" Fill="red" /></Border></Grid></Window>

This is the result:

I have converted WPF application .net 3.5 (VS 2008)  to .Net 4.5 (VS2013) and I am trying to run this application and I am getting below exception   

A first chance exception of type 'System.TypeInitializationException' occurred in PresentationFramework.dll
Additional information: The type initializer for 'System.Windows.Application' threw an exception.

In VS2008 and .Net 3.5 its working fine but after converting I am getting this exception in VS2013 and .Net 4.5 .

Am I missing something in settings ?

Thanks.
