I am using Infragistics Ultrawebgrid. When User Press Delete key on particular row in grid , the particular Row need to be delete. Its Working Fine.

I Used DropDownList with in UltrawebGrid. And bind the values using Stored Procedure. The Dropdownlist containing list of items ( ex. Item1,Item2,Item4,Item5,Item6....).

i used after cell updation( Client side event in ultrawebgrid) to avoid to choose same item.When user choose same item it says 'this item already exist'.

When the user choose item , the price and weight of the item will appear in that row.

it may be a situation that , after choosing of items (say for example item1,item2,item3 ) , the user may delete any one of the selected item( say for example item1).

So He press delete button on item1, And So the item is deleted.

My problem is after delete of item (item1) in Ultrawebgird , if i choose another row(item4) it say 'This item already Exist
(In that grid there is no such item Exist).
'.What i need to do?
