Gridview 最匹配的重载方法具有一些无效参数

[pdsnet]

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName =="AddClass")
        {
              TextBox tb = GridView1.FooterRow.RenderControl("TBClassName") as TextBox;
 }}

[pdsnet]

 <asp:TemplateField HeaderText="栏目名称">
            <EditItemTemplate>
                <asp:TextBox ID="TBClassName" runat="server" Text='<%# Bind("SD_ClassName") %>'></asp:TextBox>
            </EditItemTemplate>
            <ItemTemplate>
                <asp:Label ID="Label1" runat="server" Text='<%# Bind("SD_ClassName") %>'></asp:Label>
            </ItemTemplate>
            
                <FooterTemplate>
                        <asp:TextBox ID="TBClassName" Text='' runat="server"></asp:TextBox>
                    </FooterTemplate>
        </asp:TemplateField>

模板列内容

[pdsnet]

ClassModel.SD_ClassName = ((TextBox)GridView1.FooterRow.RenderControl("TBClassName")).Text;

这样也不行

用FindContronl试试

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName =="AddClass")
        {
              TextBox tb = (TextBox)GridView1.FooterRow.FindControl("TBClassName");
 }
}

还有你的控件是不是在母版里边，如果是的话，要xxMaster.FindControl(GridView1),然后在在GridView1里边FindControl("TBClassName")
