GridView模板列控件数据绑定

Question

下面的GridView已经进行了数据绑定，如何将模板列DropDownList从另一个数据表查询，得到的DataSet给DropDownList，每一行的下拉菜单内容是一样的。
                    <asp:GridView ID="gdvTemplet" runat="server" BorderColor="#EAE9E6" CellPadding="0"
                        Height="205px" HorizontalAlign="Center" Width="90%" AutoGenerateColumns="False"
                        BorderWidth="1px" OnPreRender="gdvTemplet_PreRender" 
                        onrowdatabound="gdvTemplet_RowDataBound">
                        <RowStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                        <Columns>
                            <asp:TemplateField HeaderText="日期">
                                <ItemTemplate>
                                    <asp:Label ID="lbldate" runat="server" Text="Label"></asp:Label>

Answer 1

在RowDataBound事件中查找dropDownList ,找到后绑定它就行了
e.Row.Cells[dropDownList所在列].FindControl("dropDownList名称")

Answer 2

        e.Row.Cells[3].FindControl("drop1").DataSource=;
没有这个属性啊。

Answer 3

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
   if (e.Row.RowType == DataControlRowType.DataRow) 
   { 
      DropDownList ddl = (DropDownList)e.Row.FindControl("DropDownList1"); 
      ddl.DataSource = ds;
      ddl.DataBind();     } 
}
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit))
{
DropDownList ddl = (DropDownList)e.Row.FindControl("DropDownList1");
if (ddl != null)
{
ddl.DataSource = ds;
      ddl.DataBind(); }
}
}
