Change Web Service method client side?

[Schmidty]

I am looking to change the web service method via a client side, and was wondering if there is a way to do it. I could not find one myself.

The context I am using it in is alongside a dropdownlist. The combobox searches for records based on the type selected in the dropdownlist. I change the method for when the list changes. I am trying to reduce my server side calls, and would love to be able to handle all this clientside.

Hello Schmidty,

You can change the name of the Web Method (or the Web Service path) in the following way:

var webServiceSettings = comboBox.get_webServiceSettings();
webServiceSettings.set_method("MethodName");
//webServiceSettings.set_path("WebServicePath");

Hi,

Say I want to have a multi-column RadComboBox AND I want to use the virtual scrolling option.

In that case, the WCF service would need to return a RadComboBoxData object instead of an IList<T>. How can I bind my data to the template in that case ? (Of course, I want everything to be client-side).

Thank you,

Eric

Hi Eric Routhier,

Achieving this would require a client-side template mechanism, which unfortunately MS dropped right before the official release of ASP.NET 4.0. Luckily you can use a version of the mechanism from one of the Previews as described in this blog post.

Until there is an official Template Engine this would be a possible solution. 

I hope it helps.

Kind regards,

Thank you for your fast reply Simon,

I implemented the mecanism in this preview and it works great for multi-column.

However as I said there are limitations. Since the webservice in this particular mecanism returns an IList<> instead of a RadComboBoxData, I cannot implement virtual scrolling correctly.

Normally I set the EndOfItems property in the webservice and return the RadComboBoxData object to the control. Without setting the EndOfItems property, the scrolling never seems to reach the end.

Is there a solution for this particular issue regarding virtual scrolling ?

Thank you,

Eric

Hello Eric Routhier,

Although the example in the blog post uses an IList<> to return the data you can as well use RadComboBoxData in the same way (as in this demo).

I hope this helps.
