Populate DropDownList from DataSource (ASP.NET)

Question

I have an SQL Data Source which selects all rows of a table. I need to populate a dropdownlist with a certain field ('percentage') of all the rows, and when one is clicked to make the 'value' the rows 'id' field.

Is there a simple way of doing this? Thanks

You would want this:

<asp:DropDownList id="ddl_Items" runat="Server" DataTextField="percentage" 
     DataValueField="id" DataSourceId="sds_Items" />

<asp:SqlDataSource id="sds_Items" ...........other stuff........ />

You don't need to worry about assigning the value on click. Just do it when you load the DropDownList in the first place.
