DropdownList: How to select by value programaticly?

[Northern]

I have an ASP DropdownList populated. What I want is to
select a new item, in my code, by set a datavale to
dropdownlist's selectedItem.Value property. I did the
following:

MyDropdown.SelectedItem.Value = "value 1"

Even though the "value 1" is in the dropdownlist's data
value collection, the dropdown's datatext doesn't change.

What am I doing wrong here? How should I do this?

Please help!

You should say

MyDropdown.SelectedIndex = <Index of the Item you want to select.>

Hi,

If I understand what you're after, you need to determine the index of the valueyou are seeking and then set the SelectedIndex property with that. The examplebelow might be what you need. Let us know?

Private Sub Button1_Click _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click
DropDownList1.SelectedIndex = _
DropDownList1.Items.IndexOf _
(DropDownList1.Items.FindByValue("Green"))
End Sub

'--------------------------------------------------------- ------ <form id="Form1" method="post" runat="server">
<p>
<asp:dropdownlist id="DropDownList1" runat="server"> <asp:listitem value="Red">Red</asp:listitem>
<asp:listitem value="Blue">Blue</asp:listitem>
<asp:listitem value="Green">Green</asp:listitem>
</asp:dropdownlist></p>
<p>
<asp:button id="Button1" runat="server" text="SelectGreen"></asp:button></p>
</form>
