Hi! I'm trying to add new row in NOT edit mode, but new row always in edit mode. Is it possible to add new row in NOT edit mode?

Example: 


public class CustomKeyboardCommandProvider : DefaultKeyboardCommandProvider
	{
		private GridViewDataControl parentGrid;

		public CustomKeyboardCommandProvider(GridViewDataControl grid)
		 : base(grid)
		{
			this.parentGrid = grid;
		}

		public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
		{
			List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();

			if (key == Key.Enter)
			{
				commandsToExecute.Clear();
				commandsToExecute.Add(RadGridViewCommands.CommitEdit);
				commandsToExecute.Add(RadGridViewCommands.BeginInsert);
				commandsToExecute.Add(RadGridViewCommands.CommitEdit);
				
				this.parentGrid.ChildrenOfType<GridViewScrollViewer>().First().ScrollToEnd();
			}

			return commandsToExecute;
		}
	}

Hello,

I am currently working with RadDocking and trying to achieve the following scenario: I have three RadSplitContainers named left, middle, and right. My goal is to make the middle RadSplitContainer auto resizable when either the left or right Rad containers are set to auto hide. In other words, I want the middle container to automatically adjust its size to accommodate the space left by the hidden containers. Could you please guide me on how to achieve this behavior?

Thank you

Here is my code:

 <telerik:RadDocking  BorderThickness="0" Name="RadDocking" >
     <telerik:RadSplitContainer Orientation="Vertical" InitialPosition="DockedLeft"  Width="270" Height="840">
         <telerik:RadPaneGroup Name="TopLeft"  TabStripPlacement="Top" VerticalAlignment="Top"  Height="200 " >
             <telerik:RadPane Name="TopLeft1" Header="TopLeft1" >
             </telerik:RadPane>
             <telerik:RadPane Name="TopLeft2" Header="TopLeft2" />
         </telerik:RadPaneGroup>
         <telerik:RadPaneGroup Name="BottomLeft" TabStripPlacement="Top" >
             <telerik:RadPane Name="BottomLeft1" Header="BottomLeft2">
             </telerik:RadPane>
             <telerik:RadPane Name="BottomLeft2" Header="BottomLeft2" >
             </telerik:RadPane>
         </telerik:RadPaneGroup>
     </telerik:RadSplitContainer>
     <telerik:RadSplitContainer   Width="600" >
         <telerik:RadPaneGroup Background="GhostWhite"  >
             <telerik:RadPane  Name="Middle1" Header="Middle" Tag="Blue" CanUserClose="True" Background="Transparent" >
             </telerik:RadPane>
         </telerik:RadPaneGroup>
     </telerik:RadSplitContainer>
     <telerik:RadSplitContainer  InitialPosition="DockedRight" Name="TopRight" Width="350" Height="640">
         <telerik:RadPaneGroup >
             <telerik:RadPane Header="TopRight" >
             </telerik:RadPane>
         </telerik:RadPaneGroup>
     </telerik:RadSplitContainer>
 </telerik:RadDocking>

Thank you!

Is there a way to drag from a radtreeview control and get the drop event in a C++ Windows window.  We do get the event, but we do not know how to get access to the data.   Can we override the drag and drop and do our own implementation?

Mike

I have a complex merged table in RadRichTextBox. I want to know when I copy that table, what is copied to clipboard? I can paste it into microsoft word no issues manually. 

I am just wanting to know is it XML that is copied? What is on the clipboard when you used right click copy?

Hi,

I use this behavior to manage multiple selection on radgridview (with selection mode = "extended" and with GridViewSelectColumn)

It works but when I try to initialize the selection with some items at the end of initialization I receive the OnSelectionChanged that remove all the elements selected but the first.

public class GridViewMultiSelect : Behavior<RadGridView>
{
	protected override void OnAttached()
	{
		base.OnAttached();
		AssociatedObject.DataContextChanged += OnDataContextChanged;
		AssociatedObject.SelectedItems.CollectionChanged += OnSelectedItemsChanged;
		AssociatedObject.SelectionChanging += OnSelectionChanged;
		AssociatedObject.Items.CollectionChanged += OnItemsChanged;
	}

	private void OnSelectionChanged(object? sender, SelectionChangingEventArgs e)
	{
		
	}

	private void OnItemsChanged(object? sender, NotifyCollectionChangedEventArgs e)
	{
	}

	private void Select(IEnumerable<NsMisuraViewWithType> misure)
	{
		foreach (var item in misure)
		{
			AssociatedObject.SelectedItems.Add(item);
		}
	}

	private void OnDataContextChanged(object? sender, DependencyPropertyChangedEventArgs e)
	{
		if (AssociatedObject.DataContext is LoadedMeasurmentsVM viewModel)
		{
			viewModel.SelectAction = Select;
			SetSelectMeasurements();
		}
	}

	private void SetSelectMeasurements()
	{
		if (AssociatedObject.DataContext is LoadedMeasurmentsVM viewModel)
		{
			foreach (var item in AssociatedObject.SelectedItems)
			{
				if (viewModel.SelectedMeasurements.All(m => m.Misura.Id != ((NsMisuraViewWithType)item).Misura.Id))
				{
					viewModel.SelectedMeasurements.Add((NsMisuraViewWithType)item);
				}
			}
		}
	}

	private void OnSelectedItemsChanged(object? sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
	{
		SetSelectMeasurements();
	}

	protected override void OnDetaching()
	{
		base.OnDetaching();
		AssociatedObject.DataContextChanged -= OnDataContextChanged;
		AssociatedObject.SelectedItems.CollectionChanged -= OnSelectedItemsChanged;
	}
}

Hi,

in my project there is one RadGridView is present. Inside it there is GridViewComboBoxColumn but whenver I am selecting other item from that comboboxcell, binded property setter is not being called and as a result datacontext also remains same.

But whenever cell of that combobox column loses the focus property setter is called and as a result datacontext is fixed.

 So, I found one workaround that is I added UpdateSourceTrigger=PropertyChanged property for my DataMemberBinding like below:
DataMemberBinding="{Binding ****, UpdateSourceTrigger=PropertyChanged}"


So it started working whenever I am selecting other item from that comboboxcell, binded property setter is being called and as a result datacontext also updated.

But the issue is that whenever 
comboboxcell loses its focus then again binded property setter is called the second time, which I don't want.

I have a telerik radRichTextbox that I need to set some defaults on for all areas that it is dynamically generated but nothing I am doing is working.

Here is my XAML set up below.
        <telerik:HtmlDataProvider RichTextBox="{Binding ElementName=radRichTextBox}" Html="{Binding MyRichText, Mode=TwoWay, NotifyOnValidationError=true, TargetNullValue='', ValidatesOnExceptions=true}">
            <telerik:HtmlDataProvider.FormatProvider>
                <telerik:HtmlFormatProvider>
                    <telerik:HtmlFormatProvider.ExportSettings>
                        <telerik:HtmlExportSettings DocumentExportLevel="Fragment"
ImageExportMode="AutomaticInline"
StyleRepositoryExportMode="DontExportStyles"
StylesExportMode="Inline"
ExportEmptyDocumentAsEmptyString="True"      
/>
                    </telerik:HtmlFormatProvider.ExportSettings>
                </telerik:HtmlFormatProvider>
            </telerik:HtmlDataProvider.FormatProvider>
        </telerik:HtmlDataProvider>

<telerik:RadRichTextBox x:Name="radRichTextBox" DocumentInheritsDefaultStyleSettings="True" Foreground="black" FontFamily="Times New Roman" FontSize="12"   Padding="10">
</telerik:RadRichTextBox>


What is the proper way to default to SINGLE line spacing and fontsize 12 with font family of Times New Roman?

Obviously the user should be able to change if they wish but I need it to atleast default initially to these values.
