Question

在C＃asp.net vs05上工作。我对gridview模板字段进行了组合。

<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource3">
            <Columns>
                <asp:BoundField DataField="StudentID" HeaderText="StudentID" ReadOnly="True" SortExpression="StudentID" />
                <asp:TemplateField HeaderText="DivisionName" SortExpression="DivisionName">
                    <ItemTemplate>
                        <asp:Label ID="lblDivisionName" runat="server" Text='<%# Bind("DivisionName") %>'
                            Width="116px"></asp:Label><br />
                        <asp:DropDownList ID="DropDownList1" runat="server">
                        </asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="StudentName" SortExpression="StudentName">
                    <EditItemTemplate>
                        <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("StudentName") %>'></asp:TextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="Label2" runat="server" Text='<%# Bind("StudentName") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:ButtonField ButtonType="Button" Text="Update" />
            </Columns>
        </asp:GridView>

现在我想用下面的代码填充这个组合？

 DropDownList1.DisplayMember = "CommercialRegionName";
            foreach (object oItem in collection)
            {
                DropDownList1.Items.Add(oItem);
            }

如何从网格中获取组合控件ID

您可以使用以下代码：在aspx中将gridview的 OnRowDataBound 设置为 OnRowDataBound =“GridView3_RowDataBound”

然后将以下代码放在aspx.cs页面中。

protected  void GridView3_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DropDownList DropDownList1 =(DropDownList) e.Row.FindControl("DropDownList1");
            DropDownList1.DisplayMember = "CommercialRegionName";
            foreach (object oItem in collection)
            {
                DropDownList1.Items.Add(oItem);
            }

        }
    }
