Hello, everyone.

  I used to use the DataGridVew. Rows (a). DefaultCellStyle. BackColor attribute in DataGridVew.

 Now I want to implement：

   DataGridVew1. Rows (a). DefaultCellStyle. BackColor = Color. Red.

How do I implement it in RadGridView? Who can help me?

Hi Telerik,

   I am looking for a feature on the RadGridView which changes the Group value. As shown the attached screenshot, I want to change the value of the Country group from Argentina to Austria. After changing, the RadGridView will show the Country group of Austria with 5 rows within instead of showing 2 rows for Austria. Can you please help advise me for this feature? I am still searching in the forum while waiting for your response. Thank you very much.

   Regards,

   Tan.
