It seems you have logical error in your code so you try to initialize a variable of type dictionary with a string, however without showing us your code it impossible to help you out...

This is a JavaScript code sample, where the error is from some .NET code - probably this 'webservices/LeadManagement.asmx/UpdateLeadmanage'...So your code has no use for our case, please add the relevant code!

Naina2 16-Jun-14 8:54am

this is the webmethod

public string UpdateLeadmanage(int leadId, string enquiry, string desc, string category)
{
DTOLeadManage dto = new DTOLeadManage();
dto.LeadId = leadId;
dto.Enquiry = enquiry;
dto.category_description = desc;
dto.category = category;
DALLeadManagement dal = new DALLeadManagement();
return dal.UpdateLeadmanage(dto);

}

Naina2 16-Jun-14 8:54am

this is the proc

public string UpdateLeadmanage(DTOLeadManage dto)
{

string result = string.Empty;
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "proc_update_lead";
cmd.Parameters.AddWithValue("@lead_id", dto.LeadId);
cmd.Parameters.AddWithValue("@enquiry", dto.Enquiry);
cmd.Parameters.AddWithValue("@category_desc", dto.category_description);
cmd.Parameters.AddWithValue("@category", dto.Category_Id);
result = "error";
try
{
con.Open();
cmd.ExecuteNonQuery();

}
catch (Exception ex)
{
throw ex;
}
finally
{
con.Close();
}
return result;
}

We are closer - on which line do you get the error? What type of the left side variable on that line?

Naina2 16-Jun-14 9:07am

left side variable ??

Kornfeld Eliyahu Peter 16-Jun-14 9:08am

left-side-variable = right-side-variable, like dto.LeadId = leadId, where dto.LeadId is the left and leadId is the right...

my proc one code is not calling by the debbuger

Kornfeld Eliyahu Peter 16-Jun-14 9:13am

I didn't got you. The line causes the exception not part of any code you posted here? So where is it?

Naina2 16-Jun-14 9:23am

no the code is not throwing any exception ... i have just put the debugger on the code and the debugger is not calling on the code

Kornfeld Eliyahu Peter 16-Jun-14 9:27am

But there is an exception! And an exception means bug in some code - show us the code!

ArunRajendra 16-Jun-14 7:40am

Put the code.

Naina2 16-Jun-14 8:19am

please see above one is my code ..plz have a look

Rahul Kumar 16-Jun-14 8:48am

Error in server side code not in client side. so you need to debug and paste the code where the error occur.

Vi(ky 16-Jun-14 8:49am

you can't solve server side error using JavaScript.

Try this :

JavaScript

$.ajax({
url: 'webservices/LeadManagement.asmx/UpdateLeadmanage',
type: "POST",
dataType: 'json',
cache: false,
contentType: 'application/json; charset=utf-8',
data: "{'leadId':"+ leadid +",'enquiry':'"+enquiry+"','desc':'"+desc+"','category':'"+category+"'}",
success: function (result) {
    alert(result.d);
},
error: function(err){ alert('error'); }
});

Solution 1

Dear,

Replace below line

Old :
data: JSON.stringify(sdata),
sdata += "leadId:'" + leadid + "',";

NEW
data: sdata,
sdata += "leadId:" + leadid + ",";
