I'm using a RadComboBox to search through clients via WebService
<telerik:RadComboBox ID="txtcontraente" runat="server" EmptyMessage="Seleziona un cliente" LoadingMessage="Caricamento in corso..." WebServiceSettings-Method="GetText" WebServiceSettings-Path="/Modules/WS/TContraente_radws_fullname.asmx" MinFilterLength="3" EnableLoadOnDemand="true" MarkFirstMatch="false" Style="max-width: 300px" Width="100%" OnClientKeyPressing="OnClientKeyPressing" DropDownWidth="400px">
<ClientItemTemplate>
<table style="width: 100%;">
<tr>
<td>#= Attributes.Nominativo #
</td>
<td style="text-align: right;">#= Attributes.DataNascita #
</td>
</tr>
<tr>
<td>#= Attributes.Convenzione #
</td>
<td style="text-align: right;">#= Attributes.Societa #
</td>
</tr>
</table>
<hr style="padding: 0px; margin: 0px;"></hr>
</ClientItemTemplate>
</telerik:RadComboBox>The problem I'm having is that sometimes requests overlap and are received at wrong times.
E.g. I search for 'abcd' (which would yield no results), then I delete the 'd' and search becomes 'abc' (which should yield results).
The problem is that sometimes the 'abcd' request is received after the 'abc' request, thus yielding no results.

Hello Dante,
I have made a few tests and the ComboBox seems to be working as expected.
Here is a short video showing that: http://somup.com/c36ii7veV5
Please double-check our documentation for the WebService and Client Templates to see if there is anything missing.
If you wish to test my sample, below you can find the entire code I used.
