Question

I have a WPF datagrid and I would like to display a message saying “No Records Found” in the middle of the Datagrid.

One way I can see of doing this is to add a single datarow that spans all the columns and whos height is the height of the datagrid, then centre the text in the row.

The main thing Im struggling with is programatically adding the row to teh datagrid.

Is this possible or is there an easier way to do this?

Answer 1

Put the ‘No Records Found’ message in a TextBlock instead, and show/hide the TextBlock depending on whether the DataGrid has data.

<Grid>

  <DataGrid x:Name="_dataGrid" />

  <TextBlock 
    HorizontalAlignment="Center"
    VerticalAlignment="Center"
    Visibility="{Binding ElementName=_dataGrid, Path=HasItems, Converter={StaticResource BooleanToInverseVisibilityConverter}, Mode=OneWay}">
      No Records Found
  </TextBlock>

</Grid>

EDIT: Source for BooleanToInverseVisibilityConverter (I have a bunch of handy converters like this always available to me in my WPF projects)

public class BooleanToInverseVisibilityConverter : IValueConverter {

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {
        return (bool) value ? Visibility.Collapsed : Visibility.Visible;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) {
        return null;
    }

}
