Here Mudassar Ahmed Khan has explained how to use a DataTable as a temporary storage table in ASP.Net for storing the records that we need for processing in ViewState or Session variables. The concept is to create a dynamic DataTable, store some values in it and then keep the DataTable either in ViewState or Session depending on whether you want it only on the page or throughout the application respectively. In order to illustrate this concept I will make use an ASP.Net GridView control on which I’ll perform Edit and Update operations and the save the updated data with the temporary DataTable.

Hi Keith: I am sorry.Your code is not working. Here is the code in my form.

Dim myconn As New SqlConnection Dim myDataAdpter As New SqlDataAdapter Dim AvalibleOrdersDS As New DataSet myconn.ConnectionString = 'Server=VENKATA SQLEXPRESS;Database= MES;Truste d_Connecti on=yes' Try myconn.Open() myDataAdpter = New SqlDataAdapter('Select * from vAvailableOrders', myconn) myDataAdpter.Fill(Avalible OrdersDS) dgvAvilableOrders.AutoGene rateColumn s = False dgvAvilableOrders.DataSour ce = AvalibleOrdersDS.Tables(0) For Each row As DataGridViewRow In Me.dgvAvilableOrders.Rows row.Cells(0).Value = row.Index Next Catch ex As Exception End Try thanks Ramana. I don't think you can set an expression or a property for a DataGridViewColumn to autoincrement. I would just manually add it to the underlying DataTable and let it handle it. For example, in this code: Dim myconn As New SqlConnection Dim myDataAdpter As New SqlDataAdapter Dim AvalibleOrdersDS As New DataSet '**** Manually add your autoincrementing column to your DataTable Dim dt as DataTable = AvalibleOrdersDS.Tables(0) Dim col As New DataColumn('SrNo') col.DataType = System.Type.GetType('Syste m.Int32') '.

You know, I did a little testing with that, and it worked fine when the datasource was not set, but did not perform correctly when the datasource was set, so I modified it and found this to work correctly: Private Sub DataGridView1_RowsAdded(By Val sender As System.Object, _ ByVal e As System.Windows.Forms.DataG ridViewRow sAddedEven tArgs) _ Handles DataGridView1.RowsAdded 'Multiple rows will be added at once when you set your datasource, so loop through them. For i As Integer = e.RowIndex To (e.RowIndex + e.RowCount - 1) Me.DataGridView1.Rows(i).C ells(0).Va lue = i Next End Sub.
