DataGridViewCell.ErrorText Property .NET Framework (current version) Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.5 .NET Framework 3.0 .NET Framework 2.0 Gets or sets the text describing an error condition associated with the cell.

If the cell's value fails some validation criteria, set the ErrorText property and cancel the commit operation by setting the Cancel property of the DataGridViewCellValidatingEventArgs to true. The text you specify is then displayed by the DataGridView, and the user is prompted to fix the error in the cell's data

So when my method Main() exits, here are some key values: dgv.Rows[0].Cells[3].ErrorText contains "Only alpha-numeric characters allowed" dgv.Visible is False dgv.Rows[0].Cells[3].IsInEditMode is False Here's the pertinent code: public Main() { InitializeComponent(); dgvStationConfiguration.DataSource = FileReaderWriter.GetStationsFromConfigFile(); http://stackoverflow.com/questions/31750507/forcing-errortext-to-show-in-a-datagridview StationConfigurationValidator.ValidateAllCellsAndSetAllErrorMessages(dgvStationConfiguration); } and public static bool ValidateAllCellsAndSetAllErrorMessages(DataGridView dgv) { bool areAllCellsValid = true; foreach (DataGridViewRow row in dgv.Rows) { foreach (DataGridViewCell cell in row.Cells) { bool isCellValid = ValidateCellAndSetErrorMessage(cell); // validate all cells in order to set their error text/glyphs; this flag is just to be able to return a summary if (isCellValid == false) { areAllCellsValid = false; } } } return areAllCellsValid; } and public static bool ValidateCellAndSetErrorMessage(DataGridViewCell cell) { string columnName = cell.OwningColumn.Name; string cellValue = cell.EditedFormattedValue.ToString(); cell.ErrorText = StationConfigurationValidator.GetCellErrorMessage(columnName, cellValue); return cell.ErrorText == string.Empty; } When the method completes and the user is shown the DataGridView, no red error glyphs are visible. If I click in and then out of that cell (namely [0][3]) - the glyph appears.I get the impression that the main problem is that when the ErrorText is set (in method Main) the the DataGridView is still not visible.I'm getting so desperate that I'm thinking of this incredible hack: have a timer go off in 10ms (to allow method Main to exit) to set the ErrorText - then disable (unhook) the timer. That's such a hack I can't stand it... Just illustrating my desperation... :-(So... What do I need to do to make that gly

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 error icon not can I achieve that the cell remains in edit mode and the error-symbol is displayed too? if (...) { 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 2,02343158 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 t
