Data properties on data control 'GridView1' such as DataSource, DataSourceID, and DataMember cannot be changed during the databinding phase of the control.

You need to use DataTable.NewRow to create new DataRow object with the same schema as the DataTable.
Try this.
Try this.
Protected Sub gridview1_databound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
Dim datatable As New Data.DataTable
datatable = CType(GridView1.DataSource, Data.DataTable)
If Not datatable Is Nothing Then
Dim dataRow As Data.DataRow
'dataRow = CType(GridView1.DataSource, Data.DataRow)
dataRow = datatable.NewRow()
'dataRow.Item("serial no") = 0
'dataRow.Item("description") = 0
'dataRow.Item("making") = 0
'dataRow.Item("equipment no") = 0
'dataRow.Item("quantity") = 0
'dataRow.Item("total packets") = 0
datatable.Rows.Add(dataRow)
End If
GridView1.DataSourceID = SqlDataSource1.ID
GridView1.DataBind()
End Sub Last edited by Ramesh S; Nov 13th, 2009 at 4:44 am.
