Solution 1

Inside the CheckBox Click Event, you can get the Current GridViewRow. Then find the next Row's Index and retrieve that Row. Now, find the Image Control of this Row and do whatever you want to do.

Refer - CASCADING DROPDOWNLIST ON GRIDVIEW[^].

See the DropDownList SelectedIndexChanged Event explained in the Blog and how to get the Row inside that Event. You just need to use use CheckBox Click Event and follow the same procedure to get the Current Row. Then get the next Row Index and next Row and do as I said.
