Join them; it only takes a minute: Sign up Winforms: Problems validating a cell in a datagridview up vote 4 down vote favorite 1 I want to validate a Winforms datagridview cell error font with CellValidating. If a value was not set correctly by the user I set ErrorText and use e.Cancel, so that the cursor remains in the cell. The problem is now, that the error-symbol (and the error text) is not displayed (in the cell). When I delete e.Cancel the cell looses the focus and error-symbol is displayed. How can I achieve that the cell remains in edit mode and the error-symbol is displayed too? if (...) c# datagridview show error text { this.datagridviewX.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText = "Errortext"; e.Cancel = true; } else { this.datagridviewX.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText = ""; } c# .net winforms datagridview share|improve this question edited Oct 10 '11 at 14:35 asked Oct 10 '11 at 14:07 Kottan 2,02043158 As I say in my answer - what you are describing isn't the out of the box behaviour so you must be doing something unusual. Could you provide some code? –David Hall Oct 10 '11 at 14:19 add a comment| 1 Answer 1 active oldest votes up vote 7 down vote The behaviour you are seeing is actually due to a painting issue and not due to the error icon not being shown. What is happening is that when you set the cell's error text the icon is displayed but the text box of the cell in edit mode is painted over the icon, hence no icon shown to the user! You have two options for fixing this - one is to simply use the row's error text so instead of: this.datagridviewX.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText = "Errortext"; e.Cancel = true; You have: this.datagridviewX.Rows[e.RowIndex].ErrorText = "Errortext"; e.Cancel = true; The other option is to change the cell padding of the cell (moving the editing control) and painting the icon in. I actually found this technique for solving the problem here and reproduced their code below (in C# and not VB.N

I can watch as I set the errortooltip to have the proper data and display control (in mousemove event), yet the second I finish my mousemove event it fires the mouseleave event and resets my tooltip before the user ever has a chance to see it. I wonder what I have incorrectly done? Here's my code: Code: ' show and hide the tooltip for error Private Sub ChuteSinglesDataGridView_CellMouseMove(ByVal sender As Object, ByVal e As DataGridViewCellMouseEventArgs) Handles ChuteSinglesDataGridView.CellMouseMove If cellInError.X = e.ColumnIndex AndAlso cellInError.Y = e.RowIndex Then Dim cell As DataGridViewCell = ChuteSinglesDataGridView(e.ColumnIndex, e.RowIndex) If cell.ErrorText <> String.Empty Then If (Not errorTooltip.Active) Then errorTooltip.Show(cell.ErrorText, ChuteSinglesDataGridView, 2000) End If errorTooltip.Active = True End If End If End Sub Private Sub ChuteSinglesDataGridView_CellMouseLeave(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles ChuteSinglesDataGridView.CellMouseLeave If cellInError.X = e.ColumnIndex AndAlso cellInError.Y = e.RowIndex Then If errorTooltip.Active Then errorTooltip.Hide(ChuteSinglesDataGridView) errorTooltip.Active = False End If End If End Sub Reply With Quote Apr 2
