this is the method....

C#

public void search()
{
    int id = Convert.ToInt32(txtSearch.Value.ToString());
    ds.Clear();
    ds = (DataSet)ser.getDataID("SP_SELECT_DATA_FROM_INFO", id);
    if (ds.Tables[0].Rows.Count > 0)
    {
        grdMyGrid.DataSource = ds;
        grdMyGrid.DataBind();
    }
    else
    {
        Response.Write("No Record Found");
    }
}

now i want to call that method using a jQuery or javascript with Ajax...

JavaScript

<script type="text/javascript">
        $(document).ready(function () {
            $("#ser").click(function () {
                if (confirm("Are you sure")) {

Create your method as static and use the WebMethod[^] attribute

JavaScript

<script type="text/javascript">
        function doajax() {
            $.ajax(
            {
                url: "GridDemo.aspx/search",
                data: "flag=1",
                success: function (msg) {
                            if (msg.d) {
                                alert("Sucess");
                            } 
            }); 
       }
    </script>

In the code behind

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (Request.QueryString["flag"] != null) search();
}

public void search()
{
    int id = Convert.ToInt32(txtSearch.Value.ToString());
    ds.Clear();
    ds = (DataSet)ser.getDataID("SP_SELECT_DATA_FROM_INFO", id);
    if (ds.Tables[0].Rows.Count > 0)
    {
        grdMyGrid.DataSource = ds;
        grdMyGrid.DataBind();
    }
    else
    {
        Response.Write("No Record Found");
    }
}

I hope I was able to solve your problem.
