It works fine if I leave the cell, but I can't figure out how to display it while staying in the cell. I have seen examples where the code updates the row's errortext, but I really want to mark the cell in error. Is this possible?
Error Font
My code is:
Code Block Private Sub dg_CellValidating(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dg.CellValidating Dim val As String = e.FormattedValue.ToString Dim dgv as DataGridView = Ctype(sender, DataGridView) Dim cell as DataGridViewCell = dgv.rows(e.RowIndex).Cells(e.ColumnIndex) If val = "X" Then cell.ErrorText = "Just a test" dgv.invalidateCell(cell) 'an attempt to repaint the cell e.Cancel = True End If End Sub Any help would be appreciated.

By default when setting the ErrorText property the error icon will not appear if the cell is in edit mode. The following sample demonstrates how you can set a cell’s padding in the CellValidating event to provide spacing for the error icon. Since padding by default affects the location of the error icon the sample uses the CellPainting to move the position of the icon for painting.

Join them; it only takes a minute: Sign up Forcing ErrorText to show in a DataGridView up vote 1 down vote favorite I've Googled and Googled for this already...When my application starts, it loads a config file and displays its contents in a DataGridView - including errors found in the config file. So when my method datagridview row error 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(); 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 DataGridVie

Want to Advertise Here? Solved How to display warning icon and error icon in datagridview, Winform, and C#? Posted on 2014-05-22 .NET Programming C# 1 Verified Solution 2 Comments 2,676 Views Last Modified: 2014-05-25 Hi experts I can get my DataGridView to display Red error icon but I now need it to display Yellow warning icon. I've got my the DataSource of my DataGridView bound to a BindingSource. The DataSource of the BindingSource is bound to a BindingList of object. My object has implemented the IDataErrorInfo. During run time, whenever my object has an error text to display, DataGridView automatically displays a Red error icon in the cell that hosts the object. I now need the DataGridView to display a Yellow warning icon for warning. The problem is apparently the DataGridView doesn't allow me to modify the icon, and it reads the IDataErrorInfo of my object in order to decide display of error icon. My question is how do I change the icon from red to yellow??? Any idea please. 0 Question by:dominicwong Facebook Twitter LinkedIn Google LVL 27 Best Solution bySammy The only way to do this is by creating your own DataGrid controls and override the PaintErrorIcon method.
