Hello Team,

I am working on one web applicaiton, where we are using radgrid with linkbutton inside template column.

On click of link button we are opening radwindow with a radgrid inside.

On click of link button radwindow opens perfect with rebinding grid inside.

The issue is on click of linkbutton it refresh the grid before opening radwindow.

Can anyone help me out with this?

Thanks in Advance,
Ruchi Patel
