[Solved] Datatable errors

[Mihai Velicu]

Hi !

If I validate data at datatable level and I have errors set at the row level or at the column level how I can see them in radgridview?
With microsoft data grid they are automatically showed.

Hello Mihai Velicu,

Currently RadGridView doesn't show an error indicator automatically when the data source indicates an error. We plan to add this feature in one of our upcoming releases. However, you can use the CellFormatting event to change the cell style when there is an error in the data source:

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    DataRowView rowView = e.CellElement.RowInfo.DataBoundItem as DataRowView;
    if (rowView != null && rowView.Row.HasErrors)
    {
        e.CellElement.BackColor = Color.Red;
        e.CellElement.DrawFill = true;
        e.CellElement.ToolTipText = rowView.Row.RowError;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.BackColorProperty);
        e.CellElement.ResetValue(LightVisualElement.DrawFillProperty);
        e.CellElement.ToolTipText = string.Empty;
    }
}

I hope this helps.
