[CLOSED] Combobox, select first item

[Yevgeniy]

Hi,
I have a Combobox inside of a window, which is implemented as a user control.
ComboBox is declared this way:

<ext:ComboBox runat="server" ID="absenceCb" FieldLabel="Absence" AnchorHorizontal="100%" EmptyText="no selection" />

To fill the combo, I do the following in codebehind of user control:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!ExtNet.IsAjaxRequest)
            {
                var types= repository.GetTypes(); 
                types.ForEach(x => absenceCb.Items.Add(new ListItem(x.Name, x.Id.ToString(CultureInfo.InvariantCulture))));
            }
        }

How can I select the first item of a combobox to be selected in my combo, when I Show the window(user control)?
I tried to accomplish this with SelectedIndex="0" at markup, and by setting SelectedItem of a combobox in codebehind, but without any success.

Hi,

Please clarify how do you show a user control?

Could you provide a full sample to reproduce the problem?

Hello Daniil,
it was an error in my code, which has nothing to do with the ComboBox itself.
Please mark as closed, or even remove this thread.
