RadDropDownList in RadGrid EditItemTemplate

[ChangJun]

hi.

i'm making RadDropDownList in RadGrid EditItemTemplete. 

I works in case modify exsit rows.

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

I tried some. and i found  it happends when the text and value of the DropDownListItem is same. 

Please let me know, what's wrong with it.

Thank you.

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?
