WPF overrided datagrid how to set DatagridCell Selected style

E E Cummings560119-Jul-2013

I have overrides DataGrid. Below are my code and XAML. How can I set style to change the DataGridCell background colour when the cell is selected?

<vw:DataGridExt

   Grid.Row="1"

   AlternatingRowBackground="LightGray"

   ItemsSource="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Value,Mode=OneWay, IsAsync=True}"

   Background="White"

   AutoGenerateColumns="True"

   IsReadOnly="True"

   CanUserResizeRows="False"

   ClipboardCopyMode="IncludeHeader"

   CanUserSortColumns="True"

   CanUserAddRows="False"

   SelectionMode="Extended"/>                

 public class DataGridExt : DataGrid

 {

     public DataGridExt()

     {

         this.AutoGeneratedColumns += new EventHandler(DataGrid_AutoGeneratedColumns);

     }

 }

thanks in advance

Solution!

You have to provide a style for your DataGridCell

<Style TargetType="{x:Type
DataGridCell}">   
  <Setter Property="Background" Value="Transparent" />        
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="BorderBrush" Value="Transparent"/>     
    <Setter Property="Template">
       
<Setter.Value>
           
<ControlTemplate TargetType="{x:Type DataGridCell}">
               
<Border Background="{TemplateBinding Background}" 
                       
BorderBrush="{TemplateBinding BorderBrush}"  
                        BorderThickness="{TemplateBinding
BorderThickness}" >
                   
<ContentPresenter />
               
</Border>                              
           
</ControlTemplate>
       
</Setter.Value>
    </Setter>
    <Style.Triggers>
        <Trigger Property="IsKeyboardFocusWithin" Value="True">
            <Setter Property="BorderBrush" Value="Black" />
       
</Trigger>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Background" Value="Gray"/>
       
</Trigger>
   
</Style.Triggers>
</Style>

and set

SelectionUnit="Cell" for your DataGrid.
