The example demonstrates the usage of GridCalculatedColumn in Telerik RadGrid. You can sort, group and/or
filter these columns exactly in the same way as you would GridBoundColumn. The columns that are going to be used in
the calculation
are specified by the DataFields property while the actual calculation
is defined via the Expression property:
<Columns>
..
<telerik:GridCalculatedColumn HeaderText="Total Price" UniqueName="TotalPrice" DataType="System.Double"
DataFields="UnitPrice, UnitsInStock" Expression="{0}*{1}" FooterText="Total : " Aggregate="Sum" />
..
</Columns>
Description of this column is available in
this help article.
