How to Remove the SelectedIndex of a DropDownList?

I have an ASP.NET Web Forms that inserts values into a database, I want to reset the selected items in the

DropDownList
, how do I do it properly?? I know with
TextBoxes
I can use
TextBox1.Text = String.empty
but it doesn't seem to work with the
DropDownLists
.

Answer

For DropDownList it would be better to first add an empty string at first position of the DropDownList by using yourDropDownList.Items.Insert method and then select it. Something like this:

yourDropDownList.Items.Insert(0, new ListItem(string.Empty, string.Empty));
yourDropDownList.SelectedIndex = 0;
