Hello,

I am just checking if you require any further assistance on the matter

Hello Arpita,

I have used the provided by you XAML code in my application in order to reproduce your issue and it seems that everything goes as expected. When I hover over an item from the drop down list of the XamComboEditor, the particular item becomes highlighted. Please modify my sample application(DataGridComboModified.zip) in order to reproduce your issue.

Looking forward to hearing from you.

Hi,

    here is the style I have for that data column in the xamdatagrid. It is a xamcomboeditor + button. Below is the style that I am using, you can ignore the converters actually which is just used for enabling or disabling the buttons, and here for the dropdown I dont see the hot-tracking. In order to select an item I am click on that specific item itself, and not at any point on the row. If I take the mouse over the items then it is not highlighted (hottracked) too so I am not able to select it.
