My [requirement](https://yourviews.mindstick.com/view/85169/becoming-an-influencer-requirement-of-skills-and-knowledge) is that i need to [populate](https://www.mindstick.com/blog/60/populate-records-in-second-listbox-according-to-the-selection-in-first-list-box) city [dropdown list](https://www.mindstick.com/forum/760/dropdown-list-open-hide-behind-another-dropdown-list-on-ie-7) on the basis of state dropdown list. So i have set [autopostback](https://www.mindstick.com/interview/2074/what-is-autopostback)=[true](https://yourviews.mindstick.com/view/81326/boycott-chinese-products-dream-will-come-true) for state dropdown list and ontextchanged [event](https://www.mindstick.com/articles/167719/marquee-hire-benefits-of-event-lighting-hire-london) of state dropdown im calling my [function](https://www.mindstick.com/articles/13001/multi-statement-table-valued-user-defined-function-in-sql-server) which populates city dropdown..

Hi Ashish, \

Use SelectedIndexChanged event of the first [dropdown](https://www.mindstick.com/articles/263/ajax-toolkit-dropdownextender-in-asp-dot-net) to check for selected value & databind your 2nd dropdownlist.
