But, in case 'Add Row'. a dropdownlist is disappeared after i select item and change focus.

Hello ChangJun,

I am afraid, that I was unable to replicate the issue locally. After an attempt of insert of a new record in the RadGrid, the RadDropDownList maintains its visibility state. Here is a video,demonstrating the behavior at my end. Would you specify the version of our controls that you are using and if you had applied any custom styles?
