Hi,
I've recently added some simple data validation to my grid which are a bunch of checks that look rather like this:
if (Convert.ToInt32(e.Row.Cells["Category"].Value) == 0) { e.Cancel = true; e.Row.ErrorText = "Project Must have a Category"; }
at the end of the rowformatting event I have this:
if (e.Cancel) { if (MessageBox.Show(e.Row.ErrorText, "ERROR", MessageBoxButtons.OKCancel) == DialogResult.Cancel) { //TODO cancel row add //if (radGridView.MasterView.TableAddNewRow.IsCurrent) this.radGridView.MasterView.TableAddNewRow.CancelAddNewRow(); radGridView.EndEdit(); } }
This gets the focus out of the AddRow section. However when I click on any other row, the event fires... but the row that it's referencing is still the new row data, which means that I get the error message again and again and again! How do I properly cancel the AddRow so that the gridView can return to it's default behavior?
Thanks

Hello, Shawn,
According to the provided information, it is not very clear how exactly you setup the grid and in which event you cancel the new row. However, note that RadGridView offers the UserAddingRow event which is quite useful for handling such cases and cancelling the new row: https://docs.telerik.com/devtools/winforms/controls/gridview/rows/new-row
If you are still experiencing any further difficulties, it would be greatly appreciated you can provide more details about the setup on your end so I can simulate the behavior in a sample project on my end.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
