Hi noman nadeem,

Well, the easiest way to do that is to introduce a new property for your data objects called ShortHeading and bind to that property instead. I far as I know it is not possible to return a substring using format strings.

Another approach is to create a simple CellTemplate for that column and use a converter to trim the original value. Here is a sample:

public class SubstringConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        string stringValue = System.Convert.ToString(value);
        int lenght = System.Convert.ToInt32(parameter);

        if(lenght >= 0)
            return stringValue.Substring(0, Math.Abs(lenght));
        else
            return ReverseString(ReverseString(stringValue).Substring(0, Math.Abs(lenght)));
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }

    public static string ReverseString(string strinToReverse)
    {
        char[] stringArray = strinToReverse.ToCharArray();
        Array.Reverse(stringArray);
        return new string(stringArray);
    }
}

<UserControl.Resources>
    <local:SubstringConverter x:Key="StringConverter"/>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White">
    <telerikGrid:RadGridView Name="RadGridView1" AutoGenerateColumns="False">
        <telerikGrid:RadGridView.Columns>
            <telerikGrid:GridViewDataColumn HeaderText="Sub Heading"
                                        DataMemberBinding="{Binding subheadingname3}"
                                        TextAlignment="Left">
                <telerikGrid:GridViewDataColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock Text="{
                            Binding Path=subheadingname3,
                            Converter={StaticResource StringConverter},
                            ConverterParameter=-2}"/>
                    </DataTemplate>
                </telerikGrid:GridViewDataColumn.CellTemplate>
            </telerikGrid:GridViewDataColumn>
        </telerikGrid:RadGridView.Columns>
    </telerikGrid:RadGridView>
</Grid>

The ConverterParameter controls which part of a string is returned. When you specify a value of -2 the last two characters will be returned.

Hope this helps.
