Hi
Try the below code
Your javascript function
<script language="javascript">
function CallCodeBehind() {

alert("Call to javascript Function from Code Behind using C#.Net");

}

script>
Your code behind
protected void Page_Load(object sender, EventArgs e)
{

Page.ClientScript.RegisterStartupScript(this.GetType(), "Call My Function In C#", "CallCodeBehind()", true);
//Add your C# code function
cSharpMethod();

}
public void cSharpMethod()
{
//your code
}

Hi Ekrem Tapan,
Try this, using Ajax Web method,
Client Side:
<script type="text/javascript">
function checkMe() {
alert("hello Ekrem");
Form_name.Counting();
}
</script>
Server Side:
Ajax.Utility.RegisterTypeForAjax(typeof(Form_name));
and your code
[Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.ReadWrite)]
Public void Counting()
{
//my code is here
}

yeah sure ,
I think in your code ,everything was right except the below:
[System.Web.Services.WebMethod]
protected void Counting(object sender, EventArgs e)
{
//my code is here
}

Add the line ,above the method ,like i mentioned and try.Hope this time you will get the
solution

And if you want more details about webmethod attributes,kindly refer the below article:

It was very explained there by Abhimanyu

kindly let me know your feedback.
