Is there someone in infragistics who can help out!

Hello Rajiv,
Thank you for your post. I have been looking into the issue that you have described and using the sample that Elena has uploaded, I was not able to reproduce it. I have replaced the styles from the sample with the one that you have provided and when there is one item in the ItemsSource, the Item and the Select all item are shown. Also in the style that you are using, you have a CheckBoxIsCheckedConverter, which is not part of Elena’s solution.
Would you please provide me with the code of the CheckBoxIsCheckedConverter to test whether the issue is caused by this converter, or if possible, would you please provide me with a sample to show the issue?
Looking forward to hearing from you.
Sincerely,

Still the problem persists, when we have only 2 items the horizontal scrollbar hides the 2nd item.
Thank you for reply. As I have mentioned previously, the reason for the behavior is that the drop down’s height is calculated differently, and it is calculating how much size it will need to render all the items. When you are manually some items in the DropDown, you are breaking that logic and as I have mentioned, you should set the MinHeight of the RootPopupElement border so it have enough space to include the scrollbars and the additional content that you have added in the popup.
The functionality that you are trying to achieve is not built-in to the xamComboEditor and implementing such approaches can cause some issues, as it is in your scenarios. You can set the MinHeight of the border to a bigger value, which should provide enough space for the drop down to draw its content.
Since this is a custom functionality that is not built-in to the xamComboEditor, you can submit a new Product Idea for having header templates for the XamComboEditor. You can submit your product idea at http://ideas.infragistics.com/.
Also, if you need assistance with implementing such custom functionalities with our controls, you can contact our Consulting Service Team. You can read more details regarding the Consulting Services here: http://d3.infragistics.com/.
Please let me know if you need any further assistance on the matter.
I am just checking if you require any further assistance on the matter.
Hi Krashmir,
Still there is some problems in this solution, as when i am adding 4 items with the scroll bar, the down scrollbar button doesn't work.
Please help.
I have already answered your other forum thread:

which is similar to the last question.
