Hi,

I've looked at you sample but if you looked at my picture, you will notice that the "tooltip" is part of xamgrdi itself, like a child of another row.

Hello Erika,

What I can suggest you in order to achieve your requirement is to use a child row to show your popup information.

I have modified the sample so that the row is expanded when a text inside the cell is clicked.

In this sample, each parent row has one child row, and a child band has only one TemplateColumn defined.
If you click a cell text for “Test2” column, the child row is displayed.

Let me know if I may be of further assistance.

Thank you,
Mihoko Kamiishi

thansk! I got it working already.

Hello Erika,

Thank you for your feedback.

As far as your Expander issue goes, I haven't been able to reproduce the problem you described on my side.

I have attached the sample project I used to test this.
Please test this on your environment and let me know if it works or not.

Please note that I removed the style "DetailsExpanderStyle" from Expander since I don't know how it's implemented on your end.

Thank you,
Mihoko Kamiishi

Thanks for you help.
