If you're executing this code server-side then you won't see the combobox clear in the browser until the component has been updated, either until the page has finished executing, or if you're doing this via ajax until that process has finished and the front-end updated.

The problem will be to do with the context that you're clearing the combobox which we don't really know. You'll have to provide a bit more information about what you're doing.

The AjaxControlToolkit ComboBox behaves similarly as the standard ASP.NET DropDownList control, so technically, you can't clear the text just what you normally do with the standard TextBox control using the .Text property.

What you can do is insert an empty value to your ComboBox like this on Page_Load event:

C#

ComboBox1.Items.Insert(0, New ListItem(""))

Now, this will put an empty string in your ComboBox list. You can then call:

C#

ComboBox1.ClearSelection();

to reset the SelectedIndex to the default item or you could remove the empty value if you'd like something like:

C#

ComboBox1.Items.Remove("");
