@korchev, what is function for this even handling?
There isn't such event.
@Mengly_Pun I did this with the data filter. There is a filter event you can hook into there and execute logic.
@BassMan , How to customize that.
Example: I want to Console.WritLine("Hello World") when I click on the Filter Icon in RadzenDataGrid.
I used the data filter component, not the grid to execute the filter.
