hi guys,
i have a search form, which function is to search from database and show results in gridview, in this there are two boxes one is textbox and second is combobox, now in this one has to enter something in textbox and then select appropriate parameters from combobox as combobox is having some parammeters like name RollNo etc, and then the press search button for results. now issue m facing is, i am not able to use parameters of combobox and textbox together, means the search button should be able to check both boxes and then give results accordingly
