The Dropdownlist has OnChange and OnSelectedIndexChanged event. So When I Click the dropdown the OnChange functionality(to disable few values) works along with the OnSelectedIndexChanged and it blinks and the dropdown needs to be clicked again to view the values. How to overcome this blinking.

Thanks in advance,
Nitz.

Hi, If you disable items of dropdown list with "onchange" event, you will have to click it again to open it. The reason is on first click it will call the function which is disabling items then the drop down will cloas itself, to get refreshed. Better disable it on body's load event or event of some other controls. Hope it'll help you. Regards Ajatshatru

Hi Ajatshatru, It just worked fine. The dropdown is in a gridview and its added dynamically bu clicking a button "Add new row". So for the first time the JS function works for the dropdown but after adding a new dropdown its not taking the new dropdown's ID and the functionality is not working. Can we've any other way to solve this? Thank You, Nitz.

Hi, The Page onload functionality works fine. The mistake I did was assigned a same variable in two for loop functions. Thank You, Nitz.
