Hello, I'm implemented an AggregateFunction (CountFunction) in my GridView, but that decrease the perfomance of the loading drastically. Without the CountFunction, the Grid loads very fast, less than a second, and when i add the function, takes about 4-5 seconds to load the data, and, when I group a column and remove the group, it will take some seconds to load everything again.

 

<telerik:GridViewDataColumn.AggregateFunctions>
    <telerik:CountFunction Caption="Total: " />
</telerik:GridViewDataColumn.AggregateFunctions>

Hello Fabio,

Thank you for the provided code snippet. 

I tested the described scenario in a sample project, however I was not able to reproduce any performance degradation. That is why I am attaching the sample project I used for testing purposes. May I ask you to check it out and see how it differs from the setup on your end?

Should you need any further assistance, can you modify the sample project in order to reproduce the observed on your end scenario and send it back or send over a sample project of your own? You can open a new support ticket, since projects cannot be attached to forum posts. 

Regards,
