Additional information: Cannot access a disposed object named "DataGridTextBox".

I have a windows form and when I click on the datagrid to take me to another form I get the error Additional information: Cannot access a disposed object named "DataGridTextBox".

I am trying to close the form which has two datagrids on it.  When I click on datagrid1 I get the error but datagrid2 does not give me the error.

Thank you

Hello, running32,

I'm not sure, but suspect that the problem might be due to the line "DataGrid1.Select(hti.Row)" in your DataGrid1_MouseDown event handler.  (This line doesn't appear to be required, anyway.)

Also, I strongly suggest that you begin using "Option Explicit" and "Option Strict" in your code.  It will benefit you greatly.

Cheers,
Randy

Thank, but that wasn't it. I'm still getting the error.

Hello, running32,

You probably should also get rid of the previous line.  That is:

     DataGrid1.CurrentCell = New DataGridCell(hti.Row, hti.Column)

If that doesn't help, you might throw in a DoEvents before closing the form.  You could also try reversing the .Show and Me.Close lines, and remove the empty DataGrid1_Navigate event handler.

Cheers,
Randy
