Control.Value and Control.SelectedItem.Value
Can someone explain to me the difference between say, Dropdownlist.SelectedItem.Value and Dropdownlist.SelectedValue??

Select dropdownlist control value
Hi, I have created a dropdownlist dynamically and populated it with numbers from 1 to 10.

I'm guessing whenever the page is loaded the dropdownlist is being created again and hence it selects the first number which is 1. Can anyone tell me how to solve this problem? How do I get the value of the number I have selected from a dropdownlist which is created dynamically? Thanks in advance for ...

User Control DropDownList Selected Value Not Passed
Edited by SomeNewKid. Please post code between <code> and </code> tags. Hi, I'm using C#.
