posted

I am picking up this error in my project. i installed the latest service pack last night:

Warning 17 The Controls collection of the UltraPanel is read-only. Modify the UltraPanel.ClientArea.Controls collection

It is being triggered here:

this.frmMain_Fill_Panel.Controls.Add(this.frmMain_Fill_Panel.ClientArea);
