在ItemBouding事件给控件绑定内容

Answer 3

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1) {
if (e.Row.RowState == DataControlRowState.Edit || Convert.ToInt32(e.Row.RowState & DataControlRowState.Edit) != 0) {
DropDownList ddl = e.Row.FindControl("ddl") as DropDownList;
ddl.SelectedValue = ((HiddenField)e.Row.FindControl("Hf")).Value; }
}}
protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
{
gv.EditIndex = e.NewEditIndex;
BindData();
}
protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
gv.EditIndex = e.RowIndex;
int id = int.Parse(gv.DataKeys(e.RowIndex).Value.ToString());
string str = ((DropDownList)gv.Rows(e.RowIndex).FindControl("ddl")).SelectedValue.Trim();
}
