Text wrap for radcombobox in WPF which has AllowMultipleSelection:

<telerik:RadComboBox Grid.Column="4" Width="300" MaxWidth="300" AllowMultipleSelection="True" SelectedItem="{Binding IngredientSourceSelectedItem}" ItemsSource="{Binding IngredientSource, Mode=TwoWay }" Text="{Binding Ingredients, Mode=TwoWay}"
 IsEnabled="{Binding IsReadOnlyIngredientSource, Converter={StaticResource ReadOnlyToEnabledConverter}}" VerticalAlignment="Stretch">
</telerik:RadComboBox>

need like this: if it overflows it should be shown in next line.

Hello,

Using the information at https://docs.telerik.com/devtools/wpf/controls/radwindow/how-to/use-radwindow-as-user-control works well for using the RadWindow with Prism.

However, it appears that the window is not using the color variation of the theme. I would like to switch dynamically from Light to Dark, but have been unsuccessful.

In the App.xaml.cs in OnStartup, the first line is:

Office2019Palette.LoadPreset(Office2019Palette.ColorVariation.Dark);

Other controls change to this theme, but not the Main Window.

Any suggestions?

Thank you!

Hi everyone,

I downloaded yerstaday the testing framework (https://www.telerik.com/try/telerik-testing-framework).

And tried to use it today with a dotnet 6 wpf application and a dotnet 6 xunit test project and it seams that the testing framework has compatibility issues.

Can someone confirm it ?

Output window just blank:
<telerik:RadTreeView> 
    <telerik:RadTreeView.Items> 
        <telerik:RadTreeViewItem Header="Football" /> 
        <telerik:RadTreeViewItem Header="Tennis" /> 
        <telerik:RadTreeViewItem Header="Cycling" /> 
        <telerik:RadTreeViewItem Header="Basketball" /> 
    </telerik:RadTreeView.Items> 
</telerik:RadTreeView
Did add "standard" TreeView control and it is showing fine.
What i'm missing in Getting Started Sample?

I am using WatermarkTextbox and somehow that looks like it is disabled,
previously I was using xctk:WatermarkTextBox in this I was using KeepWatermarkOnGotFocus="True" which was helping me.

In telerik I am not getting any property as such.

Kindly help me in this.

I want like this

<telerik:RadWatermarkTextBox
                                                HorizontalAlignment="Stretch"
                                                IsReadOnly="True"
                                                Text="{Binding MaterialPartAndName,
                                                               ValidatesOnDataErrors=True}"
                                                ToolTip="{Binding MaterialPartAndName}"
                                                cal:Message.Attach="[Event MouseEnter] = [ResetSelectedItem]"
                                                WatermarkContent="Please select a material...">

                                            </telerik:RadWatermarkTextBox>

I updated our telerik to the latest NoXaml version of the libraries.

I get the following binding error:

Cannot find source for binding with reference 'ElementName=TodayButtonBorder'. BindingExpression:Path=CornerRadius; DataItem=null; target element is 'RadButton' (Name='TodayButton'); target property is 'CornerRadius' (type 'CornerRadius')

I think this is a problem within the DateTimePicker control. I don't have any controls by the name 'TodayButton'.

Can someone from telerik flag this as a problem?

This is a pretty minor issue but the #FF808080 gray appears twice in the default color picker (once at the bottom of first column and once at top of 2nd column) which can lead to a little strangeness.

If you start the color picker with this color selected, it will show both boxes as selected.


The other strangeness I was able to duplicate in the WPF demos (R1 2022SP1) is if I have the 2nd column box gray selected and close the color picker, then when I reopen it the gray at the bottom of the 1st column will be selected.

So start with this:

Click gray at bottom of 1st column, then reopen the screen. The box at the top of the 2nd color will remain selected.

There is a little bit of strangeness too when you have that shade of gray selected and then you click down into one of the "standard colors", it appears to leave the selected border around the original gray color (but does correctly put the selected border around the standard color).


Am I misinterpreting this or is this a bug?

Hello everyone,

I read the most topics with a similiar problem but nothing had worked for me.

I use WPF with MVVM and have a RadGridView. The binding from my Xaml code is with a button and a CommandParameter that passes the RadGridView to my method.

The Code looks like this

private void LoadData(object obj)
{
    RadGridView rad = obj as RadGridView;
    
    GridViewDataColumn col = new GridViewDataColumn();
    col.DataMemberBinding = new System.Windows.Data.Binding("Name");
    col.Header = "Name";

    rad.Columns.Add(col);

    //How to add now a new row to this?
}

How can I add now a new Raw with code? Something like rad.Rows.Add() does not exist.

Hope anybody can help me :-)
