[CLOSED] Manipulating ComboBox Items via DirectMethod

[ewgoforth]

Hello,

I'm trying to manipulate the list of items in an Ext.Net Combobox, but it's not working as expected.

Here's a snippet:

    <DirectMethod()> _
    Public Sub UpdateList()

        ddlMyDropdown.Items.Clear()

        Dim myDict As IDictionary = PopulateDropDown()

        If myDict.Count > 0 Then

            For Each dictItem As DictionaryEntry In myDict
                ddlMyDropdown.Items.Add(New Ext.Net.ListItem(dictItem.Value, dictItem.Key))
            Next

            ddlMyDropdown.SelectedItem.Value = "" 'Don't select anything
        Else
            ddlMyDropdown.Items.Add(New Ext.Net.ListItem("Nothing found!", "-1"))
            ddlMyDropdown.SetValue("Nothing found!")
        End If

    End Sub

If I step through my code, I see the Items collection of ddlMyDropdown get cleared and I see items getting added to it, but I don't see the changed items reflected in the contents of ddlMyDropdown after my event has finished firing.

On the other hand some similar logic that I have in the Init event of my page seems to work just fine:

Protected Sub My_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init


        If Not Ext.Net.X.IsAjaxRequest Then

                        Dim myDict As IDictionary = PopulateDropDown()
                        For Each dictItem As DictionaryEntry In myDict
                            ddlMyDropdown.Items.Add(New Ext.Net.ListItem(dictItem.Value, dictItem.Key))
                        Next

        End If

    End Sub

Hi,

Please see

If you need to rebind all data via Items collection then use the following code after Items modification

ddlMyDropdown.GetStore().DataBind();
