[Solved] Radcombobox no postback on checked items

[Kevin]

I have a radCombobox that has multiple items in the dropwdown list, when users check the items they want to see the dropwdownlist should post back and return the items they want to see but it is not doing anything and I dont know if I am getting the items properly or its just not posting back.

Here is the HTML

<telerik:RadComboBox ID="ddlRadTeam" runat="server" Width="160px" BackColor="White" ForeColor="Black" EmptyMessage="Pick Team" AutoPostBack="true" CheckBoxes="true" EnableCheckAllItemsCheckBox="true"></telerik:RadComboBox>

Here is my filldatasource

Protected Sub myRadGrid_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles myRadGrid.NeedDataSource
       Dim SqlWhere As String = ""
       Dim items As String = ""

       If rblActive.SelectedValue = Nothing Then
           SqlWhere = " where r.bitActive = 1"
           rblActive.SelectedValue = 1
       ElseIf rblActive.SelectedValue = "All" Then
           SqlWhere = ""
       ElseIf rblActive.SelectedValue = "0" Then
           SqlWhere = " where r.bitActive = 0"
       ElseIf rblActive.SelectedValue = "1" Then
           SqlWhere = " where r.bitActive = 1"
           rblActive.SelectedValue = 1
       End If

       If fillGrid = True Then
           If ddlRadTeam.CheckedItems.Count > 0 Then
               For Each item As RadComboBoxItem In ddlRadTeam.Items
                   If item.Selected Then
                       items += item.Value & ","
                   End If
               Next
           End If

           If ddlRadTeam.SelectedItem.Checked = True And rblActive.SelectedValue = "All" Then
               SqlWhere = " where r.intTeamId IN (" & items & ")"
           ElseIf ddlRadTeam.Items.Count > 0 Then
               SqlWhere += " and r.intTeamId IN (" & items & ")"
           End If
       End If
       sql = "sql select " & SqlWhere

       myRadGrid.DataSource = getData(sql)

       pnlGrid.Visible = True
   End Sub

this is my attempt to get the grid to post back using the selected index change of the combobox and the itemchecked but neither work.

Protected Sub ddlRadTeam_ItemChecked(sender As Object, e As RadComboBoxItemEventArgs) Handles ddlRadTeam.ItemChecked
       fillGrid = True
       myRadGrid.Rebind()
   End Sub

   Protected Sub ddlRadTeam_SelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs) Handles ddlRadTeam.SelectedIndexChanged
       fillGrid = True
       myRadGrid.Rebind()
   End Sub

Hello,

In order to avoid any further confusions I have attached a sample project that implements very similar scenario - selecting or checking an item from the RadComboBox control will force the RadGrid control to rebind in order to fire the NeedDataSource each time. As you can notice while debugging when user selects/checks an item the NeedDataSource server-side event handler is fired as expected. Could you please explain what exactly is different in your project?
