This tutorial demonstrates the basic function of WebFlyPostBackManager to retrieve simple-type results from a SOAP-based XML WebService page.

Drag WebFlyPostBackManager from Toolbox into a WebForm page.
Create a WebService page in the same directory and leave the name as default, which is "WebServiceSamples.asmx". It will automatically create "WebServiceSamples.cs" in the App_code folder.
Set ServiceType to WebService and ServiceUrl to WebServiceSamples.asmx (The URL path of the page) in the properties box.
Add a HTML button and named it "Call WebService".
Add the "OnResponseSuccess" Client Side Events of WebFlyPostBackManager.

Add the following code in client-side:

Script

Copy Code

<script language="javascript">
function DoClick()
{
    var FPBMan = ISGetObject("WebFlyPostBackManager1");
                                               
    // call the HelloWorld method of the specified ServiceUrl
    FPBMan.HelloWorld();
}
                       
function WebFlyPostBackManager1_OnResponseSuccess(controlId, methodName, returnValue)
{
    alert("The return value of HelloWorld method is: " + returnValue);                                     
}
</script>

Invoke DoClick() function in onclick event like the following:

Script	Copy Code
<input id="Button1" type="button" value="Call WebService" onclick="DoClick()"/>

When you click the button, it will retrieve the simple type result from the defined WebService.
