I am calling webmethod in asmx.cs file from ajax javascript by click event of button in asp.net c#. Now, in this circle button click event working fine, webmethod event also fired perfectly but after the webmethod call alert is not getting in ajax success.
Here is my code,
<code>$("#btnGetStock").click(function (e) {
var label = document.getElementById("<%=txt_labelno.ClientID%>").value;
$.ajax({
type: "POST",
url: "FillGridMethod.asmx/QuotationList",
data: JSON.stringify({ labelno: label }),
dataType: "text",
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data["ItemType"]);
}
});
});
</code>
<code>$("#btnGetStock").click(function (e) {
var label = document.getElementById("<%=txt_labelno.ClientID%>").value;
$.ajax({
type: "POST",
url: "FillGridMethod.asmx/QuotationList",
data: JSON.stringify({ labelno: label }),
dataType: "text",
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data["ItemType"]);
}
});
});
</code>

Here is the webmethod code,
<code>[WebMethod(enableSession: true)]
public void QuotationList(string labelno)
{
if (HttpContext.Current.Session["BranchId"].ToString() == null)
{
Server.Transfer("Index.aspx");
return;
}
var quotation = new List<QuotationModel>();
string constr = cn.ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
qryFillGrid = " select max(stock.ItemType) as ItemType, sum(chrgtotalprice) as chrgtotalprice from tbl_StockRunning stock " + System.Environment.NewLine;
var cmd = new SqlCommand(qryFillGrid, con);
con.Open();
var dr = cmd.ExecuteReader();
while (dr.Read())
{
var quotationModel = new QuotationModel
{
ItemType = dr[0].ToString().Trim(),
TotalCharge = Convert.ToDecimal(service.IfNullThen(dr[1], 0))
};
quotation.Add(quotationModel);
}
}
var js = new JavaScriptSerializer();
Context.Response.Write(js.Serialize(quotation));
}
</code>
