Enter Custom Text That Is Substring of Text in Items

[Richard M]

I use load on demand to load items into the combo box, however, the user can select one of those items OR enter custom text.   See the attached screen shot.   When I tab off the control, it auto selects the first matching value, even with MarkFirstMatch = false.

So if I have "ABCD" as an item in the drop down, I can add "ABB" or anything that differs, but I can not add "ABC" for example because it will just fill in the text.   It actually has "" has it's selected value when this happens, but the text is changed.   The change happens client side before reaching any code in the code behind.

OnClientItemsRequesting simply cancels the request if less than 3 chars are typed, example from the knowledge base.

<telerik:RadComboBox ID="rcbOrganizationName" Runat="server"                   
           OnSelectedIndexChanged="RcbOrganizationNameSelectedIndexChanged"

    OnItemsRequested="RcbOrganizationNameItemsRequested"

    OnClientItemsRequesting="OnClientItemsRequesting"

    EnableLoadOnDemand="true"

    AllowCustomText="True"

    AutoPostBack="True"

    EmptyMessage="Choose"

    MarkFirstMatch="false"

    EnableItemCaching="true"

    CausesValidation="false"

    TabIndex="2"                     

    ShowMoreResultsBox="false" 

    MaxLength="50"

    MaxHeight="300px"

    Width="250px">

</telerik:RadComboBox >

Hi Richard,

The Load on Demand modes demo seems to exhibit the behavior that you need. Please, see this video capture - http://screencast.com/t/xgNyEhOYP and let me know if this is what want to achieve?


All the best,
