DropDownList SelectedIndexChanged

[Janet]

Hi,

I've created a User control, where it has a DropDownList and a Textbox.
Whenever the selectedindex is changed, the textbox will show the
SelectedValue of the dropdownlist.

Code in the ascx file
private void InitializeComponent()
{
this.cboCode.SelectedIndexChanged += new
System.EventHandler(this.cboCode_SelectedIndexChanged);
this.ID = "cboCode";
this.Load += new System.EventHandler(this.Page_Load);

}

public void cboCode_SelectedIndexChanged(object sender, System.EventArgs
eCboCode_SelectedIndexChanged)
{
txtDesc.Text = cboCode.SelectedValue;
}

When I include this control in the web form, is there any handling method I
have to include to make the dropdownlist event fire? Currently, there is
nothing shown on the textbox when the selectedindex changes.

Any help will be appreciated.

Thank You.

Regards,
Janet
