如何更改网格中的行/列背景颜色？

Question

I tried to use some atributes of rowdefinition, but it doesn't help me. I also tried to use Grid.Rows[0].BackColor = Color.Red; but it doesn't work too.

   <Grid.RowDefinitions>
            <RowDefinition></RowDefinition>
            <RowDefinition></RowDefinition>
   </Grid.RowDefinitions>

Answer 1

The Grid does not provide a simple way to color its "cells".

There are ways to color them, and the most easiest is to simply use a Border :

<Grid>
    <!-- At the top so that they don't overlap anything else. -->
    <Border Background="Red" Grid.Row="0" Grid.Column="0" />
    <Border Background="Red" Grid.Row="0" Grid.Column="1" />
    ...
</Grid>

Answer 2

How can I change every cell using loop/cycle? reply !!

 <Grid x:Name="gridMain">
    <Grid.RowDefinitions>
        <RowDefinition></RowDefinition>
        <RowDefinition></RowDefinition>
    </Grid.RowDefinitions>
    <Border Background="Red" Grid.Row="0" />
    <Border Background="Blue" Grid.Row="1" />
</Grid>

you can use.

 foreach (Border item in gridMain.Children)
        {
            if (item.Background == Brushes.Blue)
                item.Background = Brushes.Red;
            else
                item.Background = Brushes.Blue;
        }
