I have a dropdown list and would like to know in the code behind if any item is selected from this dropdown list. If nothing is selected, I will be using a database value. How do I check that? Thanks,

c#, asp.net

Add First Item as --Select-- in drop down list of Items by using edit Item  

Now check for
if (DropDownList1.SelectedValue == "--Select--")
{
 // Means nothing is selected.
}
else
{
//Something is selected.
}
