How can i remove item from dropdownlist through foreach loop?

If deleting that item from the database is not applicable to the case then you can update the data source:

1. Create (generic) List
2. Iterate through items in the DropDownList
3. Each item which differs from the one you want to remove you should add to previously created List
4. Once done, List will contain all items except that one to remove; now set DropDownList.DataSource to that List
