programatically change selected item in dropdown listbox

Question

I have a text box and a drop down list box. The text box is used to enter new records for the dropdown list box. The dropdown list box is used to select from pre-existing records. What I want to do is to create a new record using the text box but then have the dropdown list box change to the newly created item. I am using the selected value from the drop down listbox in other code and need it to reflect the new record's id when a new record is created.

Any suggestions?

You can do something like this,

C#

int k = 0;

//inside your Textbox event you prefer

C#

DropDownList1.Items.Add(new ListItem(TextBox1.Text,k.ToString()));
DropDownList1.DataValueField = k.ToString();
int count = DropDownList1.Items.Count;
DropDownList1.SelectedIndex = count - 1;
