Hi,

Refering to your article on exporting the gridview to Word/Excel/PDF/CSV, I modified to code to populate the GV dynamically coz they have different data and different columns as per the selection. But after the data population, when I try to export the data it does not export any data instead for eg. in Word it just export.
Any help would be appreciated.

The code is pasted below.

**** The below is the code for populating GV ********

VB

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim dt As DataTable = GetData()
        Dim dcol As DataColumn
        Dim bfields As BoundField
 
        GridView1.Columns.Clear()
        For Each dcol In dt.Columns
            bfields = New BoundField
            bfields.DataField = dcol.ColumnName
            bfields.HeaderText = dcol.ColumnName
            GridView1.Columns.Add(bfields)
        Next
 
        GridView1.DataSource = dt
        GridView1.DataBind()
    End Sub

**** Below Code is from your samples for exporting GV data ******

VB

Protected Sub btnExportWord_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
        Response.Clear()
        Response.Buffer = True
        Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.doc")
        Response.Charset = ""
        Response.ContentType = "application/vnd.ms-word "
        Dim sw As New StringWriter()
        Dim hw As New HtmlTextWriter(sw)
        GridView1.AllowPaging = False
        GridView1.DataBind()
        GridView1.RenderControl(hw)
        Response.Output.Write(sw.ToString())
        Response.Flush()
        Response.End()
    End Sub

Public Shared Sub ExportDataSetToExcel(ds As DataSet, filename As String)
Dim response As HttpResponse = HttpContext.Current.Response

'Clean response object
response.Clear()
response.Charset = ""

'Set response header
response.ContentType = "application/vnd.ms-excel"
response.AddHeader("Content-Disposition", "attachment;filename=""" & filename & """")

'Create StringWriter and use to create CSV
Using sw As New StringWriter()
Using htw As New HtmlTextWriter(sw)
'Instantiate DataGrid
Dim dg As New DataGrid()
dg.DataSource = dt
dg.DataBind()
dg.RenderControl(htw)
response.Write(sw.ToString())
response.[End]()
