Hi All,

I am getting an error when saving my data to a datatable

"Input string was not in a correct format.Couldn't store <ClientID> in fnClientID Column. Expected type is Int32."

I was able to get past the errors by setting the data types to string and discovered the Heading was being saved to my datatable. How do I avoid this?

Code:
Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
        intGrpSize = n

        Create_ClientTable()
        

            For Each cell As DataGridViewCell In dgvClients.SelectedCells
                MessageBox.Show(cell.Value.ToString)
            Next

            'dgvClients.DataSource = ClientTable
            For Each row As DataGridViewRow In Me.dgvClients.SelectedRows()
             
            'Clientid is int32, clientname is string & fnprgcode id int32    
            _ClientTable.Rows.Add("ClientID", "ClientName", "fnPrgCode") 
            Next
        
        frmChildWindow.CreateSession()
        'Dim frm As New frmCaseNts
        'frm.ShowDialog()
        Me.Close()
    End Sub
