Coloring Gridlines in WPF Datagrid

Question

How can I set the color of the gridlines of a wpf datagrid? I can hide these lines with the property GridLinesVisibility, but I don't know how to color them. I tried it with the Borderbrush of rows and cells but I didn't succeed.

Solution 1

You have the Properties HorizontalGridLinesBrush and VerticalGridLinesBrush

Example

<DataGrid HorizontalGridLinesBrush="Green"
          VerticalGridLinesBrush="Red"
          ...>

Solution 2

You can change the VerticalGridLinesBrush and HorizontalGridLinesBrush properties of the Datagrid

 <Window.Resources>
       <SolidColorBrush x:Key="RedGridLine" Color="#FFFF4444" />
       <SolidColorBrush x:Key="BlueGridLine" Color="#554444FF"/>
    </Window.Resources>

<my:DataGrid VerticalGridLinesBrush="{StaticResource RedGridLine}"
        HorizontalGridLinesBrush="{StaticResource BlueGridLine}" >

Solution 3

To supplement the current answers, one can change the opacity at the same time in the resource to affect the gridlines:

 <Window.Resources>
     <SolidColorBrush x:Key="StackOverflowGray" Color="LightGray" Opacity=".3" />
 </Window.Resources>

...

Then the following usages has a lighter border shown in the datagrid:

<DataGrid GridLinesVisibility="All"
          HorizontalGridLinesBrush="{StaticResource StackOverflowGray}"
          VerticalGridLinesBrush="{StaticResource StackOverflowGray}"

Adding GridLinesVisibility="All" did the job for me. Thanks! +1
