Question

How can we set border and background color in the WPF grid control ,
i am creating rows and column dynamically and adding then to grid,
can we set color and border from the code behind?

Answer 1

The Background color can just be set for the entire Grid by using the Background property:

<Grid Background="Red" />

Or if you want it set for individual cells, you need to add an element to the cell that has its Background property set.

As for Borders, a Grid only contains the ShowGridLines property, which can be used to show thin dotted lines that cannot be styled.

Per MSDN:

Only dotted lines are available because this property is intended as a
design tool to debug layout problems and is not intended for use in
production quality code. If you want lines inside a Grid, style the
elements within the Grid to have borders.

So in order to add borders to your Grid, you have to add Border elements or controls that contain a Border to the Grid cells, and style those elements.

But there is an alternative. This blog post outlines how you can extend the Grid class to create a custom Grid that has properties for Grid lines. I’ve used it successfully in the past when I wanted to render grid lines, but didn’t want to fill every cell with an object.

<my:CustomGrid ShowCustomGridLines="True"
               GridLineBrush="Blue"
               GridLineThickness="1">
