What if you remove the following condition?

if (e.Row.RowIndex == 0)

Always put your code inside code block.

Thanks for the correction.

Don't think it is necessary for a single line of code containing hardly 4 or 5 words.

The dropdownlist in each row is bounded but I think the op wants when a list item is selected in first row then the dropdownlist in second should be bind.

Ah! yes you are right. My bad.

Create an even handler for dropdown selection changed in row databound event and in dropdownselectionchanged event

foreach (GridViewRow gr in GridView1.Rows)
        {
            DropDownList DDL = (DropDownList)gr.FindControl("DropDownList2");
            if (gr.RowIndex == 1)
            {
            // code to populate dropdownlist    
            }
        }
