Hello. I have a problem. I have a control and I want to try if a specific value of one property can be setted, without catching exception. So I set the value and then I restore the previuos value. Anyone know how to prevent that the control redraw between this two operations, to prevent image flickering?
 
this.SuspendLayout();

//.....

this.ResumeLayout();

Hi mevar,
There is not managed solution that works in all of the cases.
Some controls like ListBox, ListView, TreeView and ComboBox have their own
way to stop updating the control. This can be done using the method pair
BeginUpdate/EndUpdate.

However there is no method that works with all of the controls.

I said there is no managed solution because you can send WM_SETREDRAW
message to the controls window and in this way stop/resume painting the
control.
