# Alternation

**RadVirtualGrid** allows alternating its rows and columns when readability needs to be improved. This article covers the mechanism in details.

## Row Alternation

The row alternation of the control can be utilized through the **RowAlternationCount** property.

**Example 1: Setting the RowAlternationCount**

```XAML
<telerik:RadVirtualGrid x:Name="VirtualGrid" 
                        InitialColumnCount="4" 
                        InitialRowCount="4"
                        RowAlternationCount="2"/>
```

## Column Alternation

Respectively, the alternation of the columns of **RadVirtualGrid** can be manipulated through the **ColumnAlternationCount** property of the control.

**Example 2: Setting the ColumnAlternationCount**

```XAML
<telerik:RadVirtualGrid x:Name="VirtualGrid2" 
                        InitialColumnCount="4" 
                        InitialRowCount="4"
                        ColumnAlternationCount="2"/>
```

## Custom Alternation color

**RadVirtualGrid** exposes a property for altering the default background applied to the elements participating in the alternation: **AlternationBrush**.

**Example 3: Setting the AlternationBrush**

```XAML
<telerik:RadVirtualGrid x:Name="VirtualGrid3" 
                        InitialColumnCount="4" 
                        InitialRowCount="4"
								RowAlternationCount="2"
                        ColumnAlternationCount="2"
								AlternationBrush="Beige"/>
```
