Problem with the Docking Manager

Hi, I have a problem with the docking manager in that it displays the error message System.ArgumentOutOfRangeException Index out of range Must be non negative and less that the size of the collection I have enclosed a small example to show the issue. The line that fails is this.dockingManager.DockControl(this.tabConfig, this, Syncfusion.Windows.Forms.Tools.DockingStyle.Left, 150); but I dont know why. TIA WindowsApplication10_9159.zip

Hi Steven, This is not created by the Docking Manager. Please change the coding "this.groupBar1.SelectedItem = 3;" into "this.groupBar1.SelectedItem = 0;" in the TabConfiguratorUserControl.cs file. Since GroupBar has only one GroupBarItem in that control, the ArgumentOutOfRange exception occurs. Please take a look at the modified sample and let me know if it helps. Thanks for your patience. Best Regards Vijay
