    HI, 
    I have a RadGridView which item source is bind to DynamicObject. How can I apply cell style selector to specific column of RadGridView. For your information, the column is generated dynamically.

    Thank you.

    Hello Allen,

    If I understood you correctly, you can handle RadGridView's AutoGeneratingColumn event and either build the style selector programmatically or use it from XAML:

    private void radGridView_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
    {
        if (e.ItemPropertyInfo.Name == "StadiumCapacity")
        {
            var bigStadiumStyle = new Style() { TargetType = typeof(GridViewCell) };
            bigStadiumStyle.Setters.Add(new Setter() { Property = GridViewCell.BackgroundProperty, Value = new SolidColorBrush(Colors.Red) });
            bigStadiumStyle.Setters.Add(new Setter() { Property = GridViewCell.ForegroundProperty, Value = new SolidColorBrush(Colors.Yellow) });
     
            var smallStadiumStyle = new Style() { TargetType = typeof(GridViewCell) };
            smallStadiumStyle.Setters.Add(new Setter() { Property = GridViewCell.BackgroundProperty, Value = new SolidColorBrush(Colors.Yellow) });
            smallStadiumStyle.Setters.Add(new Setter() { Property = GridViewCell.ForegroundProperty, Value = new SolidColorBrush(Colors.Red) });
     
            e.Column.CellStyleSelector = new StadiumCapacityStyle()
            {
                BigStadiumStyle = bigStadiumStyle,
                SmallStadiumStyle = smallStadiumStyle
            };
        }
    }

    Here's the XAML approach:

    private void radGridView_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
    {
        if (e.ItemPropertyInfo.Name == "StadiumCapacity")
        {
            e.Column.CellStyleSelector = (StadiumCapacityStyle) App.Current.Resources["stadiumCapacityStyle"];
        }
    }

    <Application.Resources>
        <my:StadiumCapacityStyle x:Key="stadiumCapacityStyle">
            <my:StadiumCapacityStyle.BigStadiumStyle>
                <Style TargetType="telerik:GridViewCell">
                    <Setter Property="Background" Value="Red"/>
                    <Setter Property="Foreground" Value="Yellow"/>
                </Style>
            </my:StadiumCapacityStyle.BigStadiumStyle>
            <my:StadiumCapacityStyle.SmallStadiumStyle>
                <Style TargetType="telerik:GridViewCell">
                    <Setter Property="Background" Value="Yellow" />
                    <Setter Property="Foreground" Value="Red"/>
                </Style>
            </my:StadiumCapacityStyle.SmallStadiumStyle>
        </my:StadiumCapacityStyle>
    </Application.Resources>

    Please also have a look at the CellStyleSelector and Column Events articles if you have not done so already.

    Do let me know if this works for you. If that is not the case, please provide more details regarding your exact scenario and I will gladly guide you further in finding a solution.
