GridView在编辑时候怎样绑定下拉框？

我在查看的时候GridView里显示正常的数据（不显示下拉框的样子），当我点编辑的时候 有一列（比如性别一列）就显示为下拉筐的样子并且里面有值（比如是男和女），并在后台得到下拉框的值，谢谢大家帮忙。

Answer 1

把要编辑的那列数据设为模板，放一个下拉框和一个HiddenField控件，

protected void GridView1_DataBound(object sender, EventArgs e)
{
if (GridView1.EditIndex != -1)
{
for(int i=0;i<GridView1.Rows.Count;i++)
{
if (GridView1.Rows[i].RowState == (DataControlRowState.Alternate | DataControlRowState.Edit) || GridView1.Rows[i].RowState== DataControlRowState.Edit)
{
DropDownList ddl = GridView1.Rows[i].Cells[1].FindControl("ddlName") as DropDownList;
HiddenField hid = GridView1.Rows[i].FindControl("HidName") as HiddenField;
ddl.SelectedValue = hid.Value;
}
}
}
}

GridView里面编辑摸版，然后把下拉列表空间放入<ItemTemplate>里面就OK
