With Version 11.1, how can I allow UltraWebGrid row selection to put or clear checkbox on the selected row?

I'm looking for behavior similar to "label for" on a checkbox, so that when a row is selected, it will give or clear checkbox in a given row.  Here is the column markup.

 <Columns>

<igtbl:UltraGridColumn Key="ColID" Hidden="True" DataType="System.Int32" BaseColumnName="ColID">

<Footer Key="ColID"></Footer>

<Header Key="ColID"></Header>

</igtbl:UltraGridColumn>

<igtbl:UltraGridColumn Key="ColSelect" Width="30px" Type="CheckBox" DataType="System.Boolean" BaseColumnName="ColSelect"

AllowUpdate="Yes">

<Footer Key="ColSelect">

<RowLayoutColumnInfo OriginX="1"></RowLayoutColumnInfo>

</Footer>

<Header Key="ColSelect">

<RowLayoutColumnInfo OriginX="1"></RowLayoutColumnInfo>

</Header>

</igtbl:UltraGridColumn>

<igtbl:UltraGridColumn Key="ColValue" Hidden="True" BaseColumnName="ColValue">

<Footer Key="ColValue">

<RowLayoutColumnInfo OriginX="2"></RowLayoutColumnInfo>

</Footer>

<Header Key="ColValue">

<RowLayoutColumnInfo OriginX="2"></RowLayoutColumnInfo>

</Header>

</igtbl:UltraGridColumn>

<igtbl:UltraGridColumn Key="ColDisplay" Width="100%" BaseColumnName="ColDisplay">

<Footer Key="ColDisplay">

<RowLayoutColumnInfo OriginX="3"></RowLayoutColumnInfo>

</Footer>

<Header Key="ColDisplay">

<RowLayoutColumnInfo OriginX="3"></RowLayoutColumnInfo>

</Header>

</igtbl:UltraGridColumn>

</Columns>

Thanks.
