Sorry to reopen the thread. How Can I improve the performance of UltratreeControl Control, each time I click the symbol expansion , this delay in displaying the result. Before it was fast.

Any idea.

Thanks.

Thanks for all.

Good Bye.

Hi again,

You could try:

For Each col As UltraTreeNodeCell In e.Node.Cells
	col.Column.PerformAutoResize()
Next

Please let me know if this works.

Thanks for replyng, please, Could you post this code in VB.NET

1. foreach (UltraTreeNodeCell col in e.Node.Cells)  
2.             {  
3.   
4.                 col.Column.PerformAutoResize();  
5.   
6.             } 
   

Thanks.
