I have a Drop Down List that has some items in it, I have a switch set up that will clear and repopulate the drop down list from a sql server db depending on which item is chosen. When the list is repopulated from a database table I want to use an if statement to do something based on which item is chosen. I've tried to use an if statement but no matter what I try, the code checks the if statement for the original items in the drop down list, not the items that repopulated the drop down list.

View 1 RepliesThis is my first web page ever and I can't seem to find the correct way to get the selected index from a dropdown list. I don't need the selected index until the user presses the submit button. I've been testing everything I've found on the subject, but nothing is working.
I don't want the drop-down box to reset when the selection is made, which is what happens if I use postback=true or any selected index changed events. And, I still get an index of 0.
When I test, the selected index is always zero.
This runs on page load:

I have tried many of the posts that refer to setting up drop down lists but can't set them up in the content because this is a List View.
I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?
I retrieved values from database to drop down ,how can i make them as sortable.
