Hi.

I am trying to customize my month view for my special slots.

I can do it for daily and weekly, but for monthly it takes the whole slot. I want it to look like the appointments do... (i.e.: show the stack of slots if there are more than one...)

What am I doing wrong? Or cannot be done...

I am using Telerik UI for WPF R1 2023

Thanks in advance!

New Line in RadSyntaxEditor

Hi,

Editor.Document.CurrentSnapshot.GetText() returns the current text where new lines are \n characters rather than the usual \r\n.

Is there a specific reason for this behavior? Is it possible to act on some parameter to restore the usual behavior?

Thanks,

marc.

[Solved] RadDiagram custom shapes and binding (mouse-) events

Hello!

I followed the tutorial to create a custom shape for a RadDiagram in WPF:
https://docs.telerik.com/devtools/wpf/controls/raddiagram/howto/create-custom-shape

But there is no explanation on how I could add mouse interaction (or other events).

Binding normal values works fine, but if I try to bind, for example:

<Ellipse MouseDown="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=MyMouseDownFunction}" />

I receive an error: "A 'Binding' can only be set on a DependencyProperty of a DependencyObject.'".

How can I add mouse interaction to certain parts of my custom shape?

Click event not firing on first click in a Datatemplate inside a cell-edit template

Hi
Please find my below code showing the celledittemplate

<telerik:GridViewDataColumn.CellEditTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<tbcontrols:SmartSearchRadAutoCompleteBox x:Name="JournalSuggestions" AutomationProperties.AutomationId="JournalSuggestions"
Style="{StaticResource SmartControlStyle}"
SelectionMode="Single"
KeyDown="JournalSuggestions_KeyDown"

<i:Interaction.Triggers>
<i:EventTrigger EventName="SelectionChanged">
<cal:ActionMessage MethodName="AutoCompleteBoxSelectionChanged">

</cal:ActionMessage>
</i:EventTrigger>
</i:Interaction.Triggers>
<i:Interaction.Behaviors>
<behaviours:RadAutoCompleteBoxBehavior/>
</i:Interaction.Behaviors>
</tbcontrols:SmartSearchRadAutoCompleteBox>
<Button x:Name="SearchButton" Grid.Column="1"
DataContext="{Binding DataContext, RelativeSource={RelativeSource AncestorType=controls:APTPanel}}"
Click="SearchButton_Click">
<Button.Visibility>
<con:ConverterBindableBinding Binding="{Binding IsSearchAccountVisible,UpdateSourceTrigger=PropertyChanged}"
Converter="{StaticResource BooleanToVisibilityConverter}"
ConverterParameterBinding="{Binding IsSearchAccountVisible, RelativeSource={RelativeSource AncestorType={x:Type controls:APTPanel}}, UpdateSourceTrigger=PropertyChanged}">
</con:ConverterBindableBinding>
</Button.Visibility>
</Button>
</Grid>
</DataTemplate>
</telerik:GridViewDataColumn.CellEditTemplate>

If I click the "SearchButton" on first click the event does not fire, the click event fires if I click it second time.
If I remove the SmartSearchRadAutoCompleteBox control & only keep the SearchButton then it works ok.

Can someone give me code snippet having multiple controls (one radautosearchbox & one button) in datatemplate of celledittemplate or help me understand what is causing issue in my Click event

Regards,
Swapnil.

[Solved] RadCartesianChart3D cannot set initial camera position

if (mainChart.Camera is ProjectionCamera)
{
    ProjectionCamera projectionCamera = (ProjectionCamera)mainChart.Camera;

    Point3D point3D = projectionCamera.Position;
    point3D.X = 714;
    point3D.Y = -1852;
    point3D.Z = 1255;
    projectionCamera.Position = point3D;

    Vector3D vector3D = projectionCamera.LookDirection;
    vector3D.X = -114;
    vector3D.Y = 1952;
    vector3D.Z = -665;
    projectionCamera.LookDirection = vector3D;

}

I have the above code to try to set the initial camera position via the Loaded event but it does not work.
If I use the code on a keydown event it moves the camera to the position that I want.

What am I missing to make it set the initial camera position?

RadGridView WPF always expands when updating the ItemsSource

Hi,

I have a RadGridView in WPF where I use CustomGrouping for displaying it as a hierarchical structure. I set on it AutoExpandGroups="True" in order to be expanded by default. My problem is, if I manually collapse something in the RadGridView and I make an update to the list bounded to ItemsSource, the RadGridView automatically expands and does not stay as it was.

Thanks
