i have two controls one Dropdownlist and another a text and i have add button besides them. Both the ddl and textbox r populated from database. I have a gridview placed below these controls.
when a user clicks on add the gridview should populate with the selected value in ddl and the text in textbox in the gridview. If the user does it second time the new value should be appended below the previous value.
i dont want to hit the database with my each successive add clicks.
i want simple functionality just click we add values in listbox. How can we achieve this on Gridview control?
