Javascript in datagrid

[abulhassan_shock]

i have placed an image in the datagrid bound columns as e.Item.Cells(i).Text = "" it will display an image "red.gif" in the bound column. this will call a javascript fn, which will send two values to it. Its working fine. At the same time, when i click the bound column, i want to change the image to green.gif using javascript. same like toggle button. How to perform this, please its urgent.

Regards, abul.
