I have gridview with Employee Name, Emp Code, Designation. I am populating Employee Names dropdownlist with values in rowdatabound event. In edit mode of, on selection of a value in Employee Names dropdownlist, the EmpCode and Designation should change accordingly. The empCode and Designation label controls are in templatefield. I have writtern selectionchanged event for the Employee Names drodownlist,

ddlEmp.SelectedIndexChanged += new EventHandler(grd_ddlEmp_SelectedIndexChanged);

but I do not know how to change Emp Code and Designation values inside the particular row in gridview.

Answer 1

Does these things inside the SelectedIndexChanged event of the DropDownList

1. First find the row.
2. Then access the controls and change accordingly.

Pseudo Code

protected void grd_ddlEmp_SelectedIndexChanged(object sender, EventArgs e)
{
    GridView row = ((DropDownList)sender).NamingContainer as GridViewRow;
    Label Designation = row.FindControl("id of the designation label") as Label;
    Designation.Text = "new Designation Name";
}
