Customize send to forward,backward option in SettingsPaneHomeControl

[Dipti]

Hello,

In my code, for Raddiagram, default SettingsPaneHomeControl is used. In that there are options such as Bring to Front,Back,Forward,Backward.

Bring to Back, Front works properly. But Bring to forward, backward does not detect first click, and after second it works properly for some diagrams, and for some diagrams it does not work.

How i should i debug this? 

Is there any way i can change its properties?

 

Thanks in advance.

Hello Dipti,

I am not aware of any issues with the bring forward and backward commands. What they do basically is changing the ZIndex property of the selected diagram item. I guess the experienced behavior comes from the way the stack order works. Basically, the stack order of the diagram elements is determined by two factors - the ZIndex property and the order in the children collection. For example, if two shapes has ZIndex 0, the one that has bigger index in the collection that holds it will be displayed on top. Probably, this is why you need to click the button twice. 

You can extend the commands behavior by subscribing for the CommandExecuted event of RadDiagram and update the ZIndex property of the shapes you want.

private void diagram_CommandExecuted(object sender, Telerik.Windows.Controls.Diagrams.CommandRoutedEventArgs e)
{
    if (e.Command.Name.Equals("Bring Forward"))
    {
        // update ZIndex(es) if necessary
    }
}

If you want to customize the settings pane of the diagram you can check the CustomSettingsPane SDK example.
