RadPane is only opened once

[Harald]

In the program code, I create a Radpane and add it to a RadPaneGroup. The user can close the RadPane and open it in the RadRibbon Menu.

How can I realize that a RadPane is only opened once?

Hello Harald,

I am not sure that I understand your requirement. May I ask you to clarify what you mean by that you open RadPane in a RadRibbon menu? And also, how many times the pane can be opened?

The user can open different RadPanes via the ribbon menu. I would like to deny that a RadPane can be opened twice.

Hello Harald,

Can you send me some code that shows how the RadPane is created and opened by the menu? And also can you tell me what ribbon menu you are using? Maybe you can include some code that shows also the menu definition.

Hello Harald,

Thank you for the additional information.

To achieve your requirement you can check if the pane already exists in the Panes collection of the RadDocking control and add it if it is not presented there. For example:

private void ribbonButtonCalendar_Click(object sender, RoutedEventArgs e)
{
    string kalenderName = "Kalender";
    var kalenderPane = this.DockingPanel.Panes.FirstOrDefault(x => x.Name != null && x.Name.Equals(kalenderName));
    if (kalenderPane == null)
    {
        RadPane calendar = new RadPane();
        calendar.Title = kalenderName;
        calendar.Name = kalenderName;
        this.RightPaneGroup.AddItem(calendar, DockPosition.Top);
    }
}
