Set DropDownList to nothing (blank)

[=?Utf-8?B?R3JlZw==?=]

I'm trying to set a asp:DropDownList control value to blank/null for records
that have no value. But, I'm finding that even though their is no value in my
source data, it displays a record from the drop down list anyways. How can I
have the DropDownList showing nothing when no value exists?

this.lstManagerID.Text = string.empty;
this.lstManagerID.SelectItemValue = string.empty;
this.ManagerID.SelectedItem.Value = string.Empty;

None of these options set the DropDownList to show nothing.

Any suggestions?

Thx

Try this:

this.lstManagerID.Items.Clear();

There is also a Remove() method, but that is obviously only used for
removing one ListItem at a time. The code that you included in your posting
simply changes the Text or Value property of the currently selected
ListItem, but the ListItem still exists in the DropDownList. Good Luck!
