how to select with DropDownList.text

Question

I am working on an Asp.NET project and I am trying to set the selected value of a dropdown list with a text property. For example i have i.e an item in the dropdown list with text test. Programmatically can i set it to selecteditem by Text?. I am using the follwing code but is not working.

protected void Page_Load(object sender, EventArgs e)
{
    string t = "test";
    drpFunction.Text = t; 
}

But is not working. Any suggestions ?

Answer 1

drpFunction.SelectedValue = drpFunction.Items.FindByText(t).Value;

This is better way to select text. By ioden's way it will show an error

"Multiple Items Cannot be selected in DropDownList"

Answer 2

 string t = "test";
 drpFunction.ClearSelection();
 drpFunction.Items.FindByText(t).Selected = true;
