hi all,
I am developing a web page. I am using two dropdown list boxes. one as start time & the other as end time.I am setting end time to the next two hours from the start time. Now whenever i change the item in the dropdown it should automatically update both the start time and end time without pressing any button. For example In C# there is event option in combo box list called dropdown closed. How can i do this for dropdown list in ASP.NET.
