Dropdown list not showing after comma

[Arfeen Godil]

Hi guys,

I'm evaluating the Telerik ASP.NET AJAX library and one issue that's somewhat of a deal breaker is the erratic behavior of the multi column combobox.

The combobox displays the names of people in the following format 'Last name,Firstname'
It works fine until I type a character after the comma. Then I don't get any results in the combobox dropdown.

So when I search for 'SMITH,J' my SQL query brings a few records into the datatable.  But they don't get displayed in the dropdown.

At the bottom of the dropdown, I have displayed the count of records and it shows the correct number there (e.g 3) but no rows appear.

here's some code from my ASPX page

(use the customer search combobox)

<telerik:RadComboBox ID="RadCmb_CustName" AllowCustomText="true" runat="server" Width="289px"
 Height="200px" EmptyMessage="Search for Customer..." EnableLoadOnDemand="true"

ShowWhileLoading="true" ShowToggleImage="true" ShowDropDownOnTextboxClick="false"
 OnItemsRequested="RadCmb_CustName_ItemsRequested">

Hi Arfeen,

Please make sure that you've set Text property of the items to "LastName,FirstName" when binding the combobox.

Best wishes,

I am experiencing the same behavior.  However, my ResultText is returned as a single string containing a comma like "Lastname,Firstname MI".  I don't have the option to split out and I do not want to use multiple columns, just a single result containing a comma.  I am using an objectdatasource to populate.  Up to the comma, everything is fine but as soon as I type any character after the comma the combobox hangs with "Loading..." and does not filter the results any further.  If I back off one character loading goes away and everything is returned to normal.

<telerik:RadComboBox EnableAutomaticLoadOnDemand="true" 
    DataSourceID="odsEmployeeAssets" 
    DataTextField="ReturnName" DataValueField="AssetId" 
    Filter="Contains" Width="400" ShowDropDownOnTextboxClick="false" 
    AllowCustomText="false" runat="server" />
   
Our ObjectDatasource returns a custom list of objects with properties 
        Property AssetId As Integer
        Property ParentAssetId As Nullable(Of Integer)
        Property ReturnName As String

Hello William,

Could you paste here a portion of the code that populates the items in the RadComboBox?
It would be even better if you isolate the problem and send us a sample page, so we will be able to test it locally. You could open a support ticket if you want to make attachments.

All the best,
Ivana
