Navigation drawer opening when clicking on contentviewer panel not on toggle button

[JP]

I think i read this before in this forum, on the navigation drawer opening while following the pointer if it is near the position of the navigation drawer. Is there a way of restricting the opening and closing the navigation drawer using just a toggle button and not be triggered by mouse movement or hover?

Hi JP 

 

Thank you for contacting Syncfusion Support. 

 

As per your update, we understood that you just want to restrict opening and closing of NavigationDrawer on mouse movements and to want to open and close the navigation drawer just by toggle button. In order to restrict this behavior,  we need to use the following code. 

 

Code: [C#] 

 

 

var filter = navigationDrawer1.GetType().GetField("filter", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); 

dynamic navigationDrawerMouseMessageFilter = filter.GetValue(navigationDrawer1); 

NavigationDrawerMouseMessageFilter MouseMessageFilter = navigationDrawerMouseMessageFilter; 

Application.RemoveMessageFilter(MouseMessageFilter); 

 

 

 

Please find the sample for the same:

Please try this solution and let us know if it is helpful.
