Hi, there, i have come up with a dropdownlist that takes data from database. A gridview with checkbox to select and a button to submit the selected rows in gridview and selected data in dropdownlist. i am getting errors. I don't know what is the cause. The dropdownlist will have names of delivery boys(designation). At the same time how to only display rows of selected gridview only.
