Question

我有一个gridview，我有很少的记录，我在gridview顶部有一个表格单元格，带有一个文本框和一个按钮来过滤记录。如何找到该文本框的控件。

protected void GridView2_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            GridViewRow HeaderGridRow = new GridViewRow(0, 1, DataControlRowType.Header, DataControlRowState.Normal);
            TableCell HeaderCell = new TableCell();

            HeaderCell.Text = "";
            TextBox abc = new TextBox();
            HeaderCell.Controls.Add(abc);
            HeaderCell.ColumnSpan = 3;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "";
            TextBox search = new TextBox();
            search.ID = "search1";
            HeaderCell.Controls.Add(search);
            HeaderCell.ColumnSpan = 3;
            HeaderGridRow.Cells.Add(HeaderCell);
            Control ctrl = HeaderGridRow.Cells[1].Controls[0];
            TextBox tc = ctrl as TextBox;


            HeaderCell = new TableCell();

            Button btn_chk = new Button();
            btn_chk.Text = "go";
            HeaderCell.Controls.Add(btn_chk);
            HeaderCell.ColumnSpan = 1;
            btn_chk.Click += new EventHandler(btnClick);
            HeaderGridRow.Cells.Add(HeaderCell);

            //btn_chk.CommandName = "btn_chk";

            GridView2.Controls[0].Controls.AddAt(0, HeaderGridRow);


        }
    }

        html part

         <asp:GridView ID="GridView2" runat="server"            OnRowCreated="GridView2_RowCreated">   
                    <Columns>
                        <asp:TemplateField>

     <%--   <HeaderTemplate>
     Planning Id<br />
        <asp:TextBox ID="txt_planningid" runat="server"></asp:TextBox>
    </HeaderTemplate>--%>                     
                            <HeaderTemplate>
                                <asp:Label ID="Label9" runat="server" Text="S.No"></asp:Label>
                            </HeaderTemplate>

                            <ItemTemplate>
                                <asp:Label ID="Label8" runat="server" Text="<%#Container.DataItemIndex+1 %> "></asp:Label>
                            </ItemTemplate>

                        </asp:TemplateField>

                    </Columns>

                </asp:GridView>

我在rowcreated事件中使用表格单元格添加了两个文本框和一个按钮。

我认为这就是你所追求的，

将RowDataBound事件添加到Gridview

OnRowDataBound="GridView2_RowDataBound"

使用RowDataBound事件处理事件并找到Textbox：

protected void GridView2_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{

    if (e.Row.RowType == DataControlRowType.Header)
    {
        // Find the textbox
        TextBox abc = (TextBox)e.Row.FindControl("abc");

    }
}
