Why, in a RadGrid's ClientSettings Does UseStaticHeaders Need to be True in order for the FrozenColumnsCount Property to be Observed ?

[Karrie]

Greetings, 

I've read on some old forum threads that a RadGrid's ClientSettings must set UseStaticHeaders to "true" in order for FrozenColumnsCount > 0 to take effect.

We've also observed this behavior in our use of the ClientSettings.

1) Please confirm : Must UseStaticHeaders be set to "true" in order for FrozenColumnsCount > 0 to take effect ? 

2) If #1 is confirmed, Why ?   Why was the control designed this way ? 

• This dependency is not mentioned or alluded to in the Telerik documentation of the GridScrolling memebers http://www.telerik.com/help/aspnet-ajax/allmembers_t_telerik_web_ui_gridscrolling.html

• This dependency doesn't seem to make sense from a technical perspective either; in fact, it seems like it'd be harder (more complex) for Telerik to enforce/create the frozen column behavior in a UseStaticHeaders="True" scenario as compared to a UseStaticHeaders="False" due to the way UseStaticHeaders actually renders the RadGrid HTML (which is in separate HTML tables).
• This dependency doesn't seem to make logical/ use case perspective. Isn't a common scenario one where a user doesn't want the headers fixed but does want a column or two fixed ?

3) If #1 is confirmed, is this strange, undocumented dependency already fixed in the 2013 release(s)? If not, will it be decoupled soon?

Hello,

StaticHeaders needs to be enabled because are required for the frozen column functionality. Basically when you want the column to be static you mean all of its parts, this includes header cells and item cells.

May I ask why you need to have the frozen columns functionality without static headers?
