Answer 1

Use this...

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

or

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

this is proper way.......

This works in Web

ListItem li=new ListItem(); 

li.Text="Stringxyz";
li.Value="Stringxyz";       // Create object of item first and find its index.

DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(li);

This also works fine.

 drpFunction.Items.FindByText(t).Selected = true;

Answer 6

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

The SelectedValue property can be used to select an item in the list control by setting it with the value of the item. However, an exception will be thrown during postback if the the selected value doesn't match the list of values in the dropdown list.
