Hello,

I am having problems with the docking manager (6.0.2.0) at Design time again.

One of the Panels I am using in the docking manager has a Handler for the VisibleChanged-Event (so it fills its components with data the first time its actually visible)

This caused the visual studio designer (!!) to freeze (CPU 100%).
When I comment out the VisibleChanged Handler of the Panel , everything works fine.

At runtime both alternatives work.

So do events actually get fired at design time ?

Which DockPanel-Event should I handle if I want to intialize components (for example fill a RadComboBox with data) at runtime when they are first visible to the user.


Greetings

Events do get fired at design time in all windows forms components that can be loaded into the designer. You can use the DesignMode Property to implement different handling when in the Designer (for example use fake data instead of querying a database).

if (this.DesignMode)

{

return;

}
