'create an htmltextwriter which uses the stringwriter

Dim htmlWrite As New System.Web.UI.HtmlTextWriter(stringWrite)

 

 

Dim dg As New Web.UI.WebControls.DataGrid

dg.DataBind()

 

'tell the datagrid to render itself to our htmltextwriter

Simplified version just pass it a datagrid that has been populated and your response object and it should work.You don't need to display datagrid. If you have more problems i will mail you a dll that will do it for you.

 

datagridtoExcell (datagrid,response)

 

 

Public Shared Sub DataGridToExcel(ByVal dgExport As DataGrid, ByVal response As HttpResponse)

'clean up the response.object

response.Clear()

response.Charset = ""

'set the response mime type for excel

response.ContentType = "application/vnd.ms-excel"

'create a string writer

Dim stringWrite As New System.IO.StringWriter

'create an htmltextwriter which uses the stringwriter

Dim htmlWrite As New System.Web.UI.HtmlTextWriter(stringWrite)

 

'instantiate a datagrid

Dim dg As New DataGrid

' just set the input datagrid = to the new dg grid

dg = dgExport

 

' I want to make sure there are no annoying gridlines

dg.GridLines = GridLines.None

' Make the header text bold

dg.HeaderStyle.Font.Bold = True

 

' If needed, here's how to change colors/formatting at the component level

'dg.HeaderStyle.ForeColor = System.Drawing.Color.Black

'dg.ItemStyle.BackColor = System.Drawing.Color.White

'dg.BorderColor = System.Drawing.Color.White

 

 

 

'bind the modified datagrid

dg.DataBind()

'tell the datagrid to render itself to our htmltextwriter

dg.RenderControl(htmlWrite)

'output the html

response.Write(stringWrite.ToString)

response.End()

End Sub

I sent a mail but it said it could not be delivered.Here it is again.

 

 

 

Me.adapscheduler.Fill(dattable) ->> This is the adapter that you have to create your self.

 

 

 

Try this

 

Dim myCommand As New Odbc.OdbcDataAdapter("select * from item", MyConnection)

 

Dim ds As New DataSet

 

myCommand.Fill(ds, "item")

 

Excellexport.Export.exportToExcellAsp(ds.Tables("item")., Me.Response)
