How do I refresh the row background color as soon as the row is edited?

Thread ID:

Asked On November 12, 2019 09:15 AM UTC

I have a SfDataGrid with an editable list that changes color depending on current data, like this:


     public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {
var data = value as Product;

if (data.IsIgnored == true)
return new SolidColorBrush(Colors.DarkGray);
else if (data.IsInDelivery == true)
return new SolidColorBrush(Colors.LightGreen);
return DependencyProperty.UnsetValue;

I'm not sure where I got it from, needless to say it is not my "invention". Edit: It's official documentation, here: https://help.syncfusion.com/wpf/datagrid/conditional-styling?cs-save-lang=1&cs-lang=xaml#conditional-styling-of-cells-using-converter

My issue is that it works, only that the colors don't update until I scroll down the list and up to the top again. I tried refreshing the list with


but it didn't work at all.

Hi Michal, 
Thank you for contacting Syncfusion support. 
We have analyzed your query to refresh row background when row is edited. This requirement can be achieved by using RowStyleSelector  or Style.Triggers.  
Method 1: Using RowStyleSelector 
You can modify the background of the rows using StyleSelector based on the cell values at the time of loading. To update row background at runtime, you need to call the UpdateDataRow method in CurrentCellEndEdit event. Please refert to the code snippet below 
public class RowStyleSelector : StyleSelector 
        public override Style SelectStyle(object item, DependencyObject container) 
            var record = (item as DataRow).RowData as Model; 
            if (record == null) 
                return base.SelectStyle(item, container); 
            if (record.IsIgnored) 
                return App.Current.Resources["IgnoredStyle"] as Style; 
            else if(record.IsInDelivery) 
                return App.Current.Resources["DeliveredStyle"] as Style; 
            return base.SelectStyle(item, container); 
public class SfDataGridBehavior : Behavior<SfDataGrid> 
        protected override void OnAttached() 
            this.AssociatedObject.CurrentCellValueChanged += AssociatedObject_CurrentCellValueChanged; 
            this.AssociatedObject.CurrentCellEndEdit += AssociatedObject_CurrentCellEndEdit; 
        bool isValueChanged = false; 
        private void AssociatedObject_CurrentCellEndEdit(object sender, CurrentCellEndEditEventArgs e) 
            if (!isValueChanged) 
            var grid = sender as SfDataGrid; 
            //getting GridCell 
            var cell = 
                (grid.SelectionController.CurrentCellManager.CurrentCell.Renderer as GridCellRendererBase) 
            if (cell != null) 
            isValueChanged = false; 
        private void AssociatedObject_CurrentCellValueChanged(object sender, CurrentCellValueChangedEventArgs e) 
            isValueChanged = true; 
        <Style TargetType="syncfusion:VirtualizingCellsControl" x:Key="IgnoredStyle"> 
            <Setter Property="Background" Value="DarkGray"/> 
        <Style TargetType="syncfusion:VirtualizingCellsControl" x:Key="DeliveredStyle"> 
            <Setter Property="Background" Value="LightGreen"/> 
<local:RowStyleSelector x:Key="rowStyleSelector"/> 
<syncfusion:SfDataGrid x:Name="sfdatagrid" AutoGenerateColumns="False"                           
                      RowStyleSelector="{StaticResource rowStyleSelector}" 
                               ItemsSource="{Binding OrderInfoCollection}" > 
Please refer to the sample below

Method 2 : Using Style.Triggers 
Using Style.Triggers, you can bind the values directly to DataTrigger depending on which you are changing the row background. Please refer to the below code snippet 
        <Style TargetType="syncfusion:VirtualizingCellsControl"> 
                <DataTrigger Binding="{Binding IsIgnored,                            
                  UpdateSourceTrigger=PropertyChanged}" Value="True"> 
                    <Setter Property="Background" Value="DarkGray"/> 
                </DataTrigger > 
                <DataTrigger Binding="{Binding IsInDelivery,                            
                  UpdateSourceTrigger=PropertyChanged}" Value="True" > 
                    <Setter Property="Background" Value="LightGreen"/> 
Please refer to the sample for the same in the below link
