RadPaneGroup.AddItem not show content

[Yarlen]

Hello,
If I add items to a RadPaneGroup using this.MyPaneGrtoup.Items.Add(MyNewControl); the content is shows well, but if I use

 

 

this.MyPaneGrtoup.AddItem(MyNewControl, DockPosition.Left);, the content is not showing and appears a white Panel instead.

What ca I do to define and change the Dockposition programatically.

Thanks

This sounds very much like an issue I reported (which has been marked as a bug).

Does clicking on the tab of the pane or dragging it around to a different docking position make the contents visible? It did for me. I am looking for a work-around myself. It has something to do with the RadTabControl's visibility of its content.

Hello,
No the content not appears after click on the tab or  or dragging it around to a different docking position.
Thanks

Hello Yarlen,

 What is the type of the object MyNewControl? It needs to be a RadPane or to inherits from RadPane in order to work. One more thing you should notice - as this method (AddItem) is using the parent SplitContainer of the group it will not work if the group is not placed in a SplitContainer which is placed in the Docking control. That means that you shouldn't use it with groups you just created.

Here is an example that works fine:

<Grid x:Name="LayoutRoot" Background="White">
    <Grid.RowDefinitions>
        <RowDefinition Height="auto" />
        <RowDefinition />
    </Grid.RowDefinitions>

    <Button VerticalAlignment="Top" HorizontalAlignment="Stretch" Click="Button_Click" Content="Add pane" />

    <telerik:RadDocking Grid.Row="1">
        <telerik:RadSplitContainer>
            <telerik:RadPaneGroup x:Name="group">
                <telerik:RadPane />
            </telerik:RadPaneGroup>
        </telerik:RadSplitContainer>
    </telerik:RadDocking>
</Grid>

And the handler of the Button's Click event:

private void Button_Click(object sender, RoutedEventArgs e)
{
    group.AddItem(new RadPane { Header = "Some pane" }, DockPosition.Left);
}

Hello Miroslav,
This is my "Not Working Code":

  RadPane imagePanel = new RadPane();

            var imageContent = new ImageContainer(e.JpgURL);
            var toolbox = new ImageToolbox(e.JpgURL, imageContent);


            imageContent.ToolBox = toolbox;
            imagePanel.Content = imageContent;
            imagePanel.Title = e.imageNumber;

            this.OpenedImages.AddItem(imagePanel, DockPosition.Left);

where imagePanel  is a RadPane, and OpenedImages is a RadPaneGroup, like you say, but not works
Thanks!

Hello Yarlen,

 I couldn't reproduce the problem. Could you please refer to the attached project and let me know if I'm missing something.
