[Solved] Populating RadCombBox via WCF

[David Mullings]

I have been trying to figure out how to populate a RadComboBox from a WCF call, but I have been having trouble trying to figure out to configure the WebServiceSettings properties correctly. In particular, I wam trying to figure out to set the Path property to point to a WCF that is not local to the website. I have looked over the sample code provide but in all the cases that I reviewed, the .svc file is assumed to be within the same project, but what happens when the WCF service is running on another server?

For example here are the setting found in your samples:

<telerik:RadComboBox runat="server" ID="RadComboBox1" Height="100px" Skin="Vista"
EnableLoadOnDemand="true">
<WebServiceSettings Path="ComboBoxWcfService.svc" Method="LoadData" />
</telerik:RadComboBox>


What I want to do is:

<telerik:RadComboBox ID="RadComboBox1" runat="server" width="186px"

 

 

 

MarkFirstMatch="true" Skin="Web20"

 

 

 

EnableLoadOnDemand="true">

 

 

 

<WebServiceSettings Path="http://testserver/LookupService/" Method="LoadData"/>

 

 

 

 

 

Is this possible? And if so, how?

Thanks,
David

Hello David Mullings,

Unfortunately we do not support that. RadComboBox web service load on demand is based on ASP.NET Ajax which in turn uses the XMLHttpRequest object. The latter does not work however with cross domain requests for security reasons. Workarounds do exist but they are quite ugly and RadComboBox does not support them out of the box. If this is a major showstopper for you we will consider implementing a workaround as an example.
