Question

I have a Gridview like this picture. Easyly in my last column, i keep a note for that row. (Simply, i made it edit, select, update that gridview classic properties.)

As you can see, my last column has a Textbox (Multiline)

Here is my last column gridview code;

<EditItemTemplate>
            <asp:TextBox ID="txtTNOT" runat="server" Height="35" TextMode="MultiLine" DataSourceID="SqlDataSource8"></asp:TextBox>
            <asp:SqlDataSource ID="SqlDataSource8" runat="server" 
              ConnectionString="<%$ ConnectionStrings:SqlServerCstr %>" 
              SelectCommand="SELECT [T_NOT] FROM [TAKIP] WHERE T_HESAP_NO = @T_HESAP_NO ">
                <SelectParameters>
                  <asp:Parameter Name="T_HESAP_NO" Type="String" />
                </SelectParameters>
            </asp:SqlDataSource>
            </EditItemTemplate>

And then i export this Gridview to excel with this code;

protected void LinkButton1_Click(object sender, EventArgs e)
  {
    Response.Clear();
    Response.AddHeader("content-disposition", "attachment;filename=TahTakip.xls");
    Response.Charset = "";


    Response.ContentType = "application/vnd.xls";
    System.IO.StringWriter stringWrite = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
    GridView1.RenderControl(htmlWrite);
    Response.Write(stringWrite.ToString());
    Response.End();
  }

There is no problem since this step. The problem is when i open this excel file, NOT column is different the other columns. It has a Textbox like this picture;

I don’t want to be a Textbox in my Excel file. Just want a normal cell with a NOT value like left column.

How can i do that?

Answer 1

you need to export datatable instead your GridView as you have controls in gridview that can’t be export to excel

Edit: you can do like..

protected void btnExportExl_Click(object sender, EventArgs e)
{
    StringWriter sw = new StringWriter();
    HtmlTextWriter htw = new HtmlTextWriter(sw);
    string attachment = "attachment; filename=BusinessUnit.xls";
    Response.ClearContent();
    Response.AddHeader("content-disposition", attachment);

    GridView grd = new GridView();
    grd.DataSource = datatable.DefaultView; // you get the datatable from DB that will not have controls!!!
    grd.DataBind();

    grd.RenderControl(htw);
    Response.Write(sw.ToString());
    Response.Flush();
    Response.End();
}

please note, in the actual grid I have some image button and when I am exporting then I get the datatable again from DB
