Select Column
The GridViewSelectColumn derives from GridViewColumn and its content is represented by a CheckBox for each row. It differs from the GridViewCheckBoxColumn as it does not bind to data. Instead, it allows you to select a given row via a checkbox, in other words - each CheckBox's IsChecked property is bound to the IsSelected property of the corresponding row.
Example 1: Defining GridViewSelectColumn in XAML
<telerik:RadGridView AutoGenerateColumns="False">
<telerik:RadGridView.Columns>
<telerik:GridViewSelectColumn />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" />
</telerik:RadGridView.Columns>
</telerik:RadGridView>
Figure 1: The GridViewSelectColumn
If you set RadGridView's SelectionMode property to either Extended or Multiple, you will be able to select more than one row by clicking on the desired checkbox or to select all the rows by clicking on the checkbox in the header.
Example 2: Define GridViewDataColumn with Extended SelectionMode
<telerik:RadGridView AutoGenerateColumns="False"
SelectionMode="Extended">
<telerik:RadGridView.Columns>
<telerik:GridViewSelectColumn />
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" />
</telerik:RadGridView.Columns>
</telerik:RadGridView>

CheckBoxStyle and HeaderCheckBoxStyle
GridViewSelectColumn exposes two properties of type style: CheckBoxStyle and HeaderCheckBoxStyle. You can use them to style the respective checkboxes.
Example 3: Creating appropriate styles
<Style x:Key="CheckBoxStyle" TargetType="CheckBox">
<Setter Property="Background" Value="Red" />
</Style>
<Style x:Key="HeaderCheckBoxStyle" TargetType="CheckBox">
<Setter Property="Background" Value="Blue" />
</Style>
Example 4: Setting RadGridView's CheckBoxStyle and HeaderCheckBoxStyle
<telerik:GridViewSelectColumn CheckBoxStyle="{StaticResource CheckBoxStyle}"
HeaderCheckBoxStyle="{StaticResource HeaderCheckBoxStyle}"/>
</telerik:RadGridView.Columns>
