Get a handle on a dropdowlist?

[Chris Kettenbach]

Good Morning All,
How can i get a handle on this drop down list?
public void myDropDown_OnDataBinding(object sender, EventArgs e)
{
DropDownList myDropDown = (DropDownList)sender;
Debug.Write(myDropDown.SelectedItem.Value);
}

gives me an Exception Details: System.NullReferenceException: Object
reference not set to an instance of an object.


Any ideas?

Thanks,
Chris

Apparently no item is selected, thus raising the NullRefernceException.

Likely myDropDown.SelectedItem is null?

it could be that the SelectedItem object is what raising the null exception..
DropDownList myDropDown = (DropDownList)sender; should be working..
