I have a Refresh or Display problem with a DataGridView control. The control is in a ChildForm, and the first time I open the child form "MyChildFormDialog.ShowDialog()" will show all the records in the datagridview, but if I cancel this childform, and open it again, the datagridview will have all records but only the first one will be displayed, if I scroll down then the rest of the rows will be shown.
Please see the attached video to better understanding of the problem.
Here is the call to Show the childform:
Private Sub cmdAddCards_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddCards.Click
Me.BizTransactionItems1.SaveCurrentDataTableToSnapshot("CardToBeActivated")
If Me.ChildFormDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
Me.ListView1.Requery()
Else
Me.BizTransactionItems1.RestoreCurrentDataTableSnapshot("CardToBeActivated", True)
End If
End Sub
Here is the code to populate the datagridview:
Private Sub GetAvailableInactiveCards()
'-- Get the available Inactive Cards
If Me.BizTransaction1.Count > 0 Then
Me.BizTransactionItemsStock1.FillByActiveCarrier_ITemType_And_Item(Me.BizTransaction1.FK_Vendor_Carrier, Me.cboCardName.SelectedValue)
End If
Me.DataGridView1.Refresh()
Me.ShowInactiveStockQtyValue()
Me.SetObjectStateForButtons()
Me.txtQty.Focus()
Me.txtQty.SelectAll()
End Sub
Here is the call to Cancel and close the child form:
Private Sub cmdCancelActivation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdCancelActivation.Click
Me.BizTransactionItemsStock_To_Activate.Clear()
Me.BizTransactionItemsStock1.Clear()
DialogResult = Windows.Forms.DialogResult.Cancel
End Sub
All this is basic stuff, I have done this many times with a ListView without problems, but frankly working with a DataGridView is turning out to be a very unpleasant experience.
Any idea what may be happening here?
