Hi,

I need to change particular row border in some color in componentonegrid using C#. I tried with "row.Presenter.BorderBrush = Brushes.DarkRed;".
Still it is not set . How can I achieve this?

Hello,

You may create a new RowStyle with border and then, can add it in the resources like below:

 <Window.Resources >
        <Style x:Key="rowstyle" TargetType="c1:DataGridRowPresenter">
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="c1:DataGridRowPresenter" >
                        <Border BorderBrush="Blue" BorderThickness="3">
                            <Grid x:Name="Root" Margin="{TemplateBinding CellsAreaMargin}">
                       
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="ValidationStates">
                                <VisualState x:Name="Valid"/>
                                <VisualState x:Name="InvalidUnfocused">
                                    <Storyboard>
                                        <DoubleAnimationUsingKeyFrames Storyboard.TargetName="Validation" Storyboard.TargetProperty="(UIElement.Opacity)" Duration="0">
                                            <DiscreteDoubleKeyFrame KeyTime="00:00:00" Value="1"/>
                                        </DoubleAnimationUsingKeyFrames>
                                    </Storyboard>
                                </VisualState>
                                <VisualState x:Name="InvalidFocused" >
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                                <Border x:Name="BackgroundElement" Background="{TemplateBinding Background}"/>
                        <Border x:Name="UserBackground" Background="{TemplateBinding Background}"/>
                        <Border x:Name="Validation" Background="#2BFF0000" Opacity="0" />
                        <c1:DataGridCellsPanel x:Name="Cells"/>
                        <Rectangle x:Name="HorizontalGridLine" Grid.Row="1" Height="1" Fill="{TemplateBinding HorizontalGridLineBrush}" Visibility="{TemplateBinding HorizontalGridLineVisibility}" Opacity="{TemplateBinding HorizontalGridLineOpacity}" VerticalAlignment="Bottom"/>
                    </Grid>
                        </Border>
                    </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    </Window.Resources>

After doing so, you may apply it on the specific row by handling the CreatingRow event of the datagrid. Here is the code for same:

  int rowCounter = 0;
        private void c1DataGrid1_CreatingRow(object sender, C1.WPF.DataGrid.DataGridCreatingRowEventArgs e)
        {
            if (rowCounter == 1)
            { 
                e.Row.RowStyle = Resources["rowstyle"] as Style;
            }
            rowCounter++;
            }

Hello,

You may try creating style in code and then, applying it as below:

  int rowCounter = 0;
        private void c1DataGrid1_CreatingRow(object sender, C1.WPF.DataGrid.DataGridCreatingRowEventArgs e)
        {
            if (rowCounter == 1)
            {
                e.Row.RowStyle = ApplyCellStyle() as Style;
            }
            rowCounter++;
        }

        public Style ApplyCellStyle()
        {
            string str = @"<Style xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"&quot;
    xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"&quot;  xmlns:c1=""http://schemas.componentone.com/wpf/DataGrid"&quot; TargetType=""c1:DataGridRowPresenter"">
    <Setter Property=""BorderThickness"" Value=""0""/>
       <Setter Property=""Template"">
           <Setter.Value>
               <ControlTemplate TargetType=""c1:DataGridRowPresenter"" >
                       <Border BorderBrush=""Blue"" BorderThickness=""3"">
                           <Grid x:Name=""Root"" Margin=""{TemplateBinding CellsAreaMargin}"">
 
                       <VisualStateManager.VisualStateGroups>
                           <VisualStateGroup x:Name=""ValidationStates"">
                               <VisualState x:Name=""Valid""/>
                               <VisualState x:Name=""InvalidUnfocused"">
                                   <Storyboard>
                                       <DoubleAnimationUsingKeyFrames Storyboard.TargetName=""Validation"" Storyboard.TargetProperty=""(UIElement.Opacity)"" Duration=""0"">
                                           <DiscreteDoubleKeyFrame KeyTime=""00:00:00"" Value=""1""/>
                                       </DoubleAnimationUsingKeyFrames>
                                   </Storyboard>
                               </VisualState>
                               <VisualState x:Name=""InvalidFocused"" >
                               </VisualState>
                           </VisualStateGroup>
                       </VisualStateManager.VisualStateGroups>
                               <Border x:Name=""BackgroundElement"" Background=""{TemplateBinding Background}""/>
                       <Border x:Name=""UserBackground"" Background=""{TemplateBinding Background}""/>
                       <Border x:Name=""Validation"" Background=""#2BFF0000"" Opacity=""0"" />
                       <c1:DataGridCellsPanel x:Name=""Cells""/>
                       <Rectangle x:Name=""HorizontalGridLine"" Grid.Row=""1"" Height=""1"" Fill=""{TemplateBinding HorizontalGridLineBrush}"" Visibility=""{TemplateBinding HorizontalGridLineVisibility}"" Opacity=""{TemplateBinding HorizontalGridLineOpacity}"" VerticalAlignment=""Bottom""/>
                   </Grid>
                       </Border>
                   </ControlTemplate>
           </Setter.Value>
       </Setter>
   </Style>";
            return (Style)XamlReader.Parse(str);
        }
