I am using RadTreeView, there is a request to rename the name of the tree node with the following ways:
1. When the user presses "F2" key
2. When the user double clicks the tree node
3. When the user right click the mouse, select "Rename" from the context menu.

The tree node enters "editing mode" for editing.

The challenging work is to how to implement the above features with MVVM.

Can anyone provide some sample code to demo how to implement that?

Thanks in advance!

Hi, 

I tried using the export functionality of the RadGridView and I found that the ExportAsync generates an empty file. When I use the plain Export method instead, it works correctly. Can someone take a look at this and confirm whether it works or not.

 

Thanks.

Greetings,

 when using WPF UI with a tablet we occur following problem. When touching a AutoCompleteBox nothing happens.

Hope someone can enlighten me, since every other control seems to work.

 

Regards

Hi I can't seem to disable the acrylic effect on the RadTabControl. I have it nested inside a dockpanel that's inside a RadWindow, but as long as the RadWindow has acrylic applied, the RadTabControl's HeaderBackground does too, I've tried changing the IsAcrylic property for the tabcontrol in both XAML and cs and neither seem to work. It's either both the RadWindow and the RadTabControl have the transparent acrylic effect, or neither of them do. Is there something I'm missing or is this a bug?

At present, I can use "PaneStateChange" to set the size of floating window, or "ReatinPaneSizeMode" to keep floating size same with previous docking size. 

My question is that if I dock the floating window back, how can I set the docking size instead of the default stretching along the horizontal or vertical direction.

Or is there any parameter to indicate the docking process finished so that I can reset the pane size after docking.

 

Thanks

How can I achieve the following attached Image in GridView? In the example (https://docs.telerik.com/devtools/wpf/controls/radgridview/columns/column-headers), the data columns are known but in my case, I don't know the column headers to do such example. Any suggestions on how to achieve this?

Hello,

 

I am currently trying to improve the UX of my application which uses RadGridViews.

At a high level, my current workflow is as follows: I my set RadBusyIndicator binding to true, fire a background worker to perform some work on a datatable (which is binded to the RadGridView) then set RadBusyIndicator binding to false on worker completed. 

There are two problems I am encountering:

1) When the datatable has changed, the updating of the RadGridView blocks the UI thread, causing RadBusyIndicator to freeze. If the datatable is large enough, this can effectively freeze the application for quite some time. What would be the best way to show some kind of progress dialog for this?

2) The first time the RadGridView loads, the data_loaded event is fired. However when the datatable has changed and the RadGridView has updated, data_loaded event isnt fired. Is there an event I can monitor for this?

Setting focus programatically or on xaml declaration doesnt fit its purpose, when using the material theme.

The textbox gets the carret, but its not blinking, keypresses doesnt change the text, and the "selected color bar" in the bottom does not fill up.

 

suggestions??

[code]

<telerik:RadPasswordBox x:Name="txt" Background="White" WatermarkContent="Digite a Senha" HorizontalContentAlignment="Center"  Margin="20 0 20 0" WatermarkBehavior="HideOnTextEntered">
                        <telerik:RadWatermarkTextBox.InputBindings>
                            <KeyBinding Command="{Binding ValidarSenhaCommand}" CommandParameter="{Binding ElementName=txt}" Key="Enter" />
                        </telerik:RadWatermarkTextBox.InputBindings>
                    </telerik:RadPasswordBox>

 

[/code]

 

[code]

 private void UserControl_Loaded(object sender, RoutedEventArgs e)
        {
            txt.Focus();
            
        }

[/code]
