I was trying to use the FilterType="HeaderContext"
It works fine but whenever I have a GridDateTimeColumn I get an error just before the check list items requested event fires.
My column is like this:
If I comment out that column, everything works fine, but I need that column, I think I can change all the columns to a bound column and use an edit item template to get what I need, but there are lots of columns and grids in different pages where I would like to use this kind of filters, is it possible to make it work without having to change a lot in each grid??

I have prepared a sample runnable project using the code you provided, however, I was not able to replicate the error you encounter. You can find my test project attached. Also confirm that you are using the latest Q3 2015 SP1 version of the controls.
I've created a sample project using yours as base,(is a rar renamed as png, it says only images can be attached)
basically, it is composed of 2 SQLDataSources, 1 grid, and 1 tabstrip (you may notice something wrong with thee project... I chosed the wrong language... but it runs, so maybe just use the cs and aspx...)
When a Tab strip button is pressed, a rebind occurs to the grid...
When rebinding, the grid checks what tab is selected and loads one or the other data source.
When first loaded, the filters work fine, but after changing the tab the filters stop working (the popup doesn't appear)
And if changing the tab again will throw the error.
So there are 2 things that I can't figure out.... any help will be greatly appreciated.
just in case... here are the contents of the files, I used the same web.config and database
We had some problems wiith excel-like filtering in Q3 2015 release, however they are already fixed, therefore
I recommend you upgrade to the latest version (2015.3.1111) and let us know if you encounter any errors with it.
