Hello Prencia,

One way to achieve your goal is to use the built-in aggregate functions of RadGrid columns. More information about them could be find in this help topic and in this online demo.

If this approach is not applicable in your scenario, or you have some custom requirements you could try it different way:

• Find the footer item for the respective column and in its cell to set the calculated value.
• To calculate the value you need to iterate through the Items collection and for each item to get the value for the required column.

This whole logic should be done either in the SelectedIndexChanged event of the DropDown control or in the PreRender event of RadGrid.

Kind regards,
