protected void ddl1_SelectedIndexChanged(object sender, EventArgs e)

{

string foundID = String.Empty;

GridViewRow row = (GridViewRow)((sender) as Control).NamingContainer;

// getting the value from the first dropdownlist

DropDownList ddlfirst = ((sender) as DropDownList);

int ddlfirstSelectedValue = Convert.ToInt32(ddlfirst.SelectedValue);

string firstDropDownListID = ddlfirst.UniqueID;

// and now here is how

DropDownList ddlSecond = row.FindControl("ddl2") as DropDownList;

// your code

}
