Thanks. your sample works well, but when I put the same code in my program, the tooltip is never shown. (maybe it relates to other classes in my project, but I didn't find the reason to this behavior.) I can't to send you my project, it's complicated..., so I think I'll use with external tooltip (what I don't want to use with...)

thanks you for all.

Hello,

I am just checking about the progress of this issue. Let me know if you need my further assistance on this issue.

Thank you for using Infragistics Components.

Hi,

Thank you for the reply.

Are you able to run the sample I sent you in my first reply? It loads the tooltips from the data source and displays them on the cells of the grid. If you are having issues implementing this feature, please send me a sample and I will be glad to modify it in order to fulfill your requirements and show the tooltips.

I am looking forward to hearing from you.

First, thanks about the event (InitializeRow).

I have another question: why can't I see the ToolTipText never? I think I read all posts about the toolTip but no one helps. May you have an idea? Maybe another properties of ultragrid affect the tooltip?

I wrote this row before and after I update the DataSource of the ultragrid:

 ultraGrid1.DisplayLayout.Override.TipStyleCell = TipStyle.Show; 

Thanks.
