Getting Row From Modal Form

[Auguy]

VB.Net 2003. I have a DataGrid (grdPro1) on one form. I am passing a row of the grid to a modal form using a property in the modal form. When I make a change to the row in the modal form, they do not show up in grdPro1 after returning from the modal form. I have looked at the values in the PopupWorkRow after the DialogResult.OK and they are changed. As a test I added the "HELP ME" line if I cancel out of the modal form. This change shows up immediately. Not sure why the DialogResult.OK branch isn't working. There must be something really simple I'm missing here. I've tried begin and end edit on the row and also refreshing the grid. I've used properties on modal forms many times to retrieve specific values with no problems, but never a row like this. Is it because I'm calling this code from the grdPro1.MouseDown event and looking for a right click? As you can see, I need some help here.

...
Dim Row1 As Integer
Row1 = myHitTest.Row
Dim PopupWorkRow As DataRow
PopupWorkRow = dsProFile.Tables("ProFile").Rows(Row1)
Dim ChangeColumnForm As New ChangeColumnValue
ChangeColumnForm.ProRow = PopupWorkRow
If ChangeColumnForm.ShowDialog() = DialogResult.OK Then
  PopupWorkRow = ChangeColumnForm.ProRow
Else 
  PopupWorkRow("ExceptCode") = "HELP ME"
End If

ChangeColumnForm.Close()
ChangeColumnForm.Dispose()
ChangeColumnForm= Nothing

Try changing your code to this and see what happens:

...
Dim Row1 As Integer
Row1 = myHitTest.Row
Dim ChangeColumnForm As New ChangeColumnValue
ChangeColumnForm.ProRow = dsProFile.Tables("ProFile").Rows(Row1)
If ChangeColumnForm.ShowDialog() = DialogResult.OK Then
  'maybe throw in a grid refresh here
Else
  PopupWorkRow("ExceptCode") = "HELP ME"
End If

ChangeColumnForm.Close()
ChangeColumnForm.Dispose()
ChangeColumnForm= Nothing

Thanks, I'm still a little confused. It seems if I pass an integer or text to a property on the modal form and change the values in the modal form, the original value in the calling form does not change unless I explicity set it using something like variable = ModalForm.Prop1. But the row paseed seems to change as in the code you suggested without having to explicitly set it. What if I don't want the changes in the row

dsProFile.Tables("ProFile").Rows(Row1)[red].RejectChanges()[/red]

This undoes all changes to the DataRow since the last AcceptChanges call. This method is also available for DataTable and DataSet.

Thanks again. I think I see the light at the end of the tunnel, just hope it's not a train coming at me. And I have marked my calendar for Talk Like a Pirate Day!
