Thank you Mohanraj
But this event is raised at infinity.... and is very slow is not Is not applicable
ther is some workaround ?
Hi Franco,Thanks for your update.In the provided sample of last update, we have set the data source for a ComboBox column based on the ValueMember of another ComboBox column. So, the records will not be filtered and changes will not be reflect in the grid. We are little bit unclear about your scenario. Can you please elaborate the scenario or provide any screenshot/video of your exact requirement so that we could provide you a better solution at the earliest?Regards,Arulpriya
Thank you for your support
We have 2 combo in gridgoruping control (refer to screenshoot in the first my post)
tthe first contain a Taxonomoy Main when this change during the edit the Taxonomy Sub (the second combo ) need to be filtered by the valuemember in the taxonomy main;
it's a cascading lookup like a product category (Taxonomoy Main) filter the product (Taxonomy sub)
Let me know if this sample is clear
Thank you again
