//customize the TextBoxCellRenderer this.sfDataGrid.CellRenderers.Remove("TextBox"); this.sfDataGrid.CellRenderers.Add("TextBox", new GridCellTextBoxRendererExt()); public class GridCellTextBoxRendererExt : GridCellTextBoxRenderer { protected override void OnEditElementLoaded(object sender, RoutedEventArgs e) { base.OnEditElementLoaded(sender, e); var uiElement = sender as TextBox; //set the CaretIndex based on clicked text position uiElement.CaretIndex = uiElement.GetCharacterIndexFromPoint(Mouse.GetPosition(uiElement), true); } }
