    Hi Bhavik,

    First of all why do you use Drop down for 15K items.

    Based on my experience, I have had drop down lists with thousands of options and it wasn't ideal though because who wants to scroll through all of those? This is why an auto-complete of some type is more desirable for numerous reasons, especially at the end user's experience. You can use textbox and auto fill it when user enters any input. That's the alternative of it.

    For DropDownlist 15000 rows its large amount of Data. It will affect performance. you can use textbox auto fill options.

    I suggest to use 2 approaches to achieve the performance

    1 .fill the drop down values on drop down scrolling event using jquery
    2. make seperate Ajax hit after page load and fill the values

    i think , 1st approach is good and it will avoid the performance issue and only loads when user scroll down the drop down values and it s dynamic content loading. refer below link for more details
