HOW-TO
Close the RadComboBox popup when a message box is opened

DESCRIPTION
Opening a message box from RadComboBox does not close combo's popup automatically.

SOLUTION
Call the CloseDropDown() method of RadComboBox prior to displaying the message box:

C#
 
private void radComboBox1_SelectedIndexChanged(object sender, EventArgs e)   
{   
            this.radComboBox1.CloseDropDown();   
            MessageBox.Show("As a message box that requires user interaction before closing the dropdown list, this should be in front, not behind that dropdown list.\n\n\n\n\n\n\n\nThe problem is that this box is behind.");   
}   

 
VB.NET
 
Private Sub radComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)  
     Me.radComboBox1.CloseDropDown()  
     MessageBox.Show("As a message box that requires user interaction before closing the dropdown list, this should be in front, not behind that dropdown list." & Chr(10) & "" & Chr(10) & "" & Chr(10) & "" & Chr(10) & "" & Chr(10) & "" & Chr(10) & "" & Chr(10) & "" & Chr(10) & "The problem is that this box is behind.")  
End Sub  


A small C# sample project is attached to show how this works.
