GDBG : strenge problem

[Ken Lee]

Hi, Experts
I''m using two GDBG in a windows form. there are a dataset including two datatable and a relation between two datatables, one as parent datatable , the other as child datatable.
All of databound operations does well, but when parent datatable is empty, I input a first character , the row becomes editmode , then press ESC key(RejectedChanges), the application goes dowm. There is StackOverflowException exception arised, this cause by the application call the NewRowFromBuilder infinited.
Have you any idea to solve this problem?

Hi ken,

Here is one way to avoid this exception. Please try this code snippet and let us know if this helps.

private void gridDataBoundGrid1_CurrentCellRejectedChanges(object sender, EventArgs e)
{
this.gridDataBoundGrid1.Binder.EndEdit();
}

Best regards,

Hi, Calvin
I think this way is NOT work, the situation is same.I guess you test this case ONLY input first two columns, you can try input through the third column, then press ESC key, the exception shown again. I try input first two columns then press ESC key, the problem can be solved, but not for all of cases. please let me konw again how to avoid this problem. thanks

Hi Ken, Sorry for the late response. We have found a way to fix this defect. Please login in to our incident section to get a private patch for this issue. A work around for this problem is tricky. May be you could handle the CurrentCellRejectedChanges and then call the SuspendBinding, start a timer and later call the ResumeBinding. Refer to the sample for more details.
