Supress ItemsRequested event on key press

[Billy]

I am loading a rad combo box on demand (EnableLoadOnDemand="True") in the ItemsRequested event. I want this to load when the user opens the combo box but not when they type in the combo box (I have MarkFirstMatch = true). Is this possible?

Here is the code I am using for all this if it helps:

<telerik:RadComboBox ID="RadComboBox2" CssClass="DGselectPerson" runat="server" EmptyMessage="Select a Person" EnableLoadOnDemand="True" AppendDataBoundItems="false" AutoPostBack="true" DataTextField="Name" DataValueField="RecordID" EnableVirtualScrolling="true" OnClientDropDownOpening="onDropDownOpening" OnItemsRequested="RadComboBox2_ItemsRequested" MarkFirstMatch="true">

 

 

 

 

</telerik:RadComboBox>

 

Protected

 

 

Sub RadComboBox2_ItemsRequested(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs) Handles RadComboBox2.ItemsRequested

 

RadComboBox2.DataSource = GetPeople()

RadComboBox2.DataBind()

 

 

End Sub

Hello Billy Hasan,

You can achieve this in a different way:

• Set EnableLoadOnDemand to false.
• Handle the client-side DropDownOpening event in this way:

  function onDropDownOpening(sender) {
      if (sender.get_items().get_count() == 0)
          sender.requestItems("", false);
  }

Everything else in your implementation can remain the same.

I hope this helps.

Kind regards,
Simon

That worked, thank you! However SelectedIndexChanged is no longer firing when I select an item from the list.
