Use the SetColumnError method to set column errors.
To determine if any errors exist for the columns collection, use the HasErrors method. Consequently, you can use the GetColumnsInError method to retrieve all of the columns with errors.
To clear all errors for the columns collection, use the ClearErrors method.
The following example sets and gets the error description for a new column in an existing System.WinForms.DataGrid control's DataTable.
[Visual Basic]
Dim myRow As DataRow Dim t As DataTable t = DataGrid1.DataSource.DataTable myRow = t.NewRow Dim ErrorString As String ErrorString = "Replace this text." ' Use DataColumn.Contains to ensure the column exists If myRow.DataTable.Columns.Contains(1) Then myRow.SetColumnError(1, ErrorString) Console.WriteLine(myRow.GetColumnError(1)) ' Add the row t.Rows.Add(myRow) End If
