Thanks for your reply.

I am already templating GroupByRecordPresenter for displaying buttons in Group header. But couldn't figure out how to change text in header. It seems that "Description" is a dependency property which is actually displayed as the content of Group header. and this "Description"already seems to contains text of that column + summary (i.e., number of items in the group).

Here is the section from GroupByRecordPresenter template where I am displaying buttons and where I did a failed attempt to change text of group header.

Your help will be greatly appreciated.

Thanks,

Imad.

Just to clarify a bit more... I hope you got what I am mean by "Description" property. "this already seems to contains text of that column + summary (i.e., number of items in the group)." Hence I couldn't think of any way to break it in content and summary so that I can change the content text in to my desirable format.

Waiting for your response.

Thanks,

Imad.

Hello Imad,

Thank you for your feedback. I am glad that you resolved your issue and I believe that other community members may benefit from this as well. Also I will look at your other forum thraed as soon as possible.

Thanks again.

Hey Stefan can you please look into this (http://community.infragistics.com/forums/p/68353/347293.aspx#347293) issue as well.

Thanks,

Imad.

Kudos to Stefan, thanks man it worked like a charm. My bad that I couldn't figure out how to do that.

Thanks again,

Imad.

Hello Imad,

I apologize for the late response. I have been looking into your requirement and I modified the sample I sent you before, so now it works as you want. Please note that the approach I gave you is a basic approach, which you can follow to make a custom implementation of the thing you want to achieve, since there isn’t any built in functionality for it.

Hope this helps you.

I tried your solution. It fixes that problem but now it creates another problem.

Item count in the summary of header should update when new items are added but its not updating at all. When I expanded the group, new item was there in the list.

It has already taken too much time. And your help is also slow. I'll be grateful for a solution that doesn't break anything else.

Thanks,
Imad.
