call server side method from client side using script manager


>

 

 

 

Hello friends.

I am going to share with you a concept to call server side method from client side using script manager.

Step 1 : Put ScriptManager on .ASPX page.

Step 2 : Set EnablePageMethods=”True” in ScriptManager.

Step 3 : Create one static method in server side that return some value.

Step 4 : Set WebMethod attribute to above the method.

Step 5 : Create one javascript  function and call server side method using PageMethods object and set callback method as argument.

Step 6 : Create callback method where you will be able to retrieve return parameter from server side method.

See following example code

ScriptManager on the page.

<asp:ScriptManager ID="ScriptManager1"  EnablePageMethods="true" runat="server">
</asp:ScriptManager>

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, “Courier New”, courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

My server side static method

[System.Web.Services.WebMethod]
public static int Sum(int value1, int value2)
{
return value1 + value2;
}

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, “Courier New”, courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

My javascript function to call server side method and retrieve result from server side

<script language="javascript" type="text/javascript">
pageMethodConcept={
callServerSideMethod:function(){
PageMethods.Sum(3,4,pageMethodConcept.callback);

// I am passing 3 and 4 to get sum and set callback method
},
callback:function(result){
alert(result);
}
}
window.onload=pageMethodConcept.callServerSideMethod;
</script>

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, “Courier New”, courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
