Is it possible to change RowHeader Style ?

[Silvio]

Hi,

I would like to better show to the user when a record in a datagrid has been changed.

It should be nice for me, for example, to draw a red background color all the row Headers of all the records that have been changed.

I already have in the model record a bool property that identifies if the relative record has been changed.

So I ask you if it's possible to change the row Header style of each row according to the change status of the related binded record.

Thank you,

Silvio

Hi Silvio, 

You can change the background color of RowHeader when the record property changed by write the style for GridRowHeaderCell,  

<Style  TargetType= "syncfusion:GridRowHeaderCell"> 

   <Setter Property="Background" Value="{Binding Status,Converter={StaticResource converter }}"/> 

 </Style> 

 

public class CustomConverter:IValueConverter 

{ 

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 

    { 

        bool statusvalue = (bool)value; 

        if (statusvalue == true) 

            return Brushes.Red; 

        else 

            return Brushes.Green; 

 

        return value; 

    } 

 

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) 

    { 

        throw new NotImplementedException(); 

    } 

}

In the above sample, we have changed the RowHeader background based on the Status column value.

Thank you Ganesh for your answer.

This is good if you don't use SfSkinManager for grid styles.

If instead you use it, your sugestion seems not to work.

Please find here attached the same your example that I have changed applying a Blend Style to the whole window.

I'd like the red background appears only when the record is changed, otherwise I'd like the standard Blend background is applied.

But, as you can see, in this example Blend background is always applied.

What changes have I to make in order to let it work as I'd like ?

Thank you.

Hi Silvo, 

The already applied styles (setting in App.Xaml) are disabled while applying the theme through SfSkiManager in code behind. You can overcome this by setting a theme in xaml instead of code behind like below, 

<ResourceDictionary> 

            <ResourceDictionary.MergedDictionaries> 

                <ResourceDictionary Source="/Syncfusion.Themes.Blend.WPF;Component/SfDataGrid/SfDataGrid.xaml"/> 

            </ResourceDictionary.MergedDictionaries> 

 

            <local:CustomConverter x:Key="converter"/> 

            <Style TargetType= "syncfusion:GridRowHeaderCell"> 

                <!--By using converter the Background color is changed based on the business logic--> 

                <Setter Property="Background" Value="{Binding Status,Converter={StaticResource converter }}"/> 

            </Style> 

</ResourceDictionary>
