Hi Tomasz, 

 

Thanks for contacting Syncfusion support. 

 

We have checked your query “Do the action when user change the focus to the another panel of DockingManager” at our end. We have achieved your requirement by invoking the ActiveWindowChanging event of DockingManager which can be triggered when focus of the child window changing. Also we can cancel the focus changing of any child by setting Cancel event argument as true. Please find the code snippet, screenshot and sample for the same. 

 

Code Snippet: 

 

// occurs when focus of the child window changes 

            this.SyncDockingManager.ActiveWindowChanging += SyncDockingManager_ActiveWindowChanging; 

 

private void SyncDockingManager_ActiveWindowChanging(FrameworkElement sender, Syncfusion.Windows.Tools.Controls.ActiveWindowChangingEventArgs e) 

        { 

              //Do the actions 

 

            if((e.NewValue as  ContentControl).Name == "Output") 

            {   

                // handles the focus changing to the Output window 

                e.Cancel = true; 

            } 

        }
