End Google Ads 201810 - BS.net 01 --> Hi,
I have a combo box which I am populating dynamically using Datatables.
The combobox acts as a selection point from where a user selects a value and accordingly charts are generated..!
The column i am populating changes dynamically and is never the same.
Now I want to add another option "ALL" in the combo box after/before I populate the combobox...such that my combo box should have all the values frm table as well as an item " ALL " I tried doing it, but it shows error.

Can anyone help me out please. how should i go abt it..?
I am making a Windows Application using C#.

Cheers

Jimish
