The Command event occurs when postbacks are enabled and the user clicks on one of the command icons in the RadDock title bar.

The Command event handler receives two arguments:

  1. The RadDock control whose title bar contains the command icon that the user clicked. This argument is of type object, but can be cast to the RadDock type.

  2. A DockCommandEventArgs object. This object has a Command property, that provides access to the DockCommand object for the command that was clicked:

Use a Command event handler to provide a server-side implementation for custom commands or to augment the default behavior of built-in commands. For example, the following Command event handler implements a custom command that moves a docked control to the next docking position if it is not the last docked control in its parent's docking zone:

protected void RadDock1_Command(object sender, Telerik.Web.UI.DockCommandEventArgs e)
    if (e.Command.Name == "MoveDown")
        RadDock dock = (RadDock)sender;
        if (dock.DockZoneID != string.Empty)
            RadDockZone zone = (RadDockZone)dock.Parent;

            int i = dock.Index;
            if (i < zone.Docks.Count - 1)
                RadDock nextDock = zone.Docks[i + 1];
                zone.Docks[i] = nextDock;
                zone.Docks[i + 1] = dock;
Protected Sub RadDock1_Command( _
      ByVal sender As Object, _
      ByVal e As Telerik.Web.UI.DockCommandEventArgs) _
      Handles RadDock1.Command
    If e.Command.Name = "MoveDown" Then
        Dim dock As RadDock = DirectCast(sender, RadDock)
        If dock.DockZoneID <> String.Empty Then
            Dim zone As RadDockZone = DirectCast(dock.Parent, RadDockZone)
            Dim i As Integer = dock.Index
            If i < zone.Docks.Count - 1 Then
                Dim nextDock As RadDock = zone.Docks(i + 1)
                zone.Docks(i) = nextDock
                zone.Docks(i + 1) = dock
            End If
        End If
    End If
End Sub
