I have a RadGridView which contains several columns. I have Sum function for part of the columns which show decimal number. Now when I drag the columns which do not have Sum function that can show the Count function result, how to archive this? Just add Count function to those columns will show both of the result.

Hello Jimmy,

My suggestion would be to take a look at this forum thread and the attached project in it to verify whether the approach illustrated there might fit your requirements.

I copied the whole style from the solution, seems like it can work. But do I need to use the whole style? It's too complicated, I only need to show specified aggregate result on GroupRow. Any also, I got error when expand the group row, can you please help?

Hello Jimmy,

As the solution in the provided forum thread is quite old, it is possible that the provided control template has changed and that is the reason you're observing the aforementioned error.

I've taken the liberty of creating a sample project for you to have a look at based on the solution my colleague offered. However, it uses the new GroupRenderMode="Flat" which leads to better performance as described in our Grouping Modes article. Bear in mind that when using this render mode, you should target the GroupHeaderRow element instead of the GridViewGroupRow as I've done in the sample project.

Please have a look and let me know if this solution would for you.

Hello Jimmy,

In order to hide the aggregate result from the footer cell, you will need to predefine the GridViewGroupFooterCell control template, use a similar approach as the one for the GroupHeaderRow and assign a custom converter for its ItemsSource binding.
