public string SumWage()

       return temp.retpricereq(u2,str).ToString();

how sort with SortExpression="SumWage" sumwage()

1 solution

You can change your mathod to a static method like

public static string SumWage()

        return temp.retpricereq(u2,str).ToString();

Then use like

Text='<%# Class.SumWage() %>' 

// Class is the Class where your SumWage Method resides.

Hope this helps...

iam dont sorting
JoCodes 3-Oct-13 13:15pm
any error you are getting? Have you tried replacing the method with a hardcoded string and checked whether it works?
saeed1364 3-Oct-13 13:23pm
this main function

public string SumWage()
string str = string.Empty;
int u2 = int.Parse(Eval("FUserId").ToString());
if (ConstList.CheckFormatDate(Ttimef.Text.Trim()) != 0 && Ttimef.Text.Trim() != "")
str += "and [FReqDate] >= " + ConstList.DateStoM(Ttimef.Text.Trim()).Date.ToShortDateString();

if (ConstList.CheckFormatDate(Ttimet.Text.Trim()) != 0 && Ttimet.Text.Trim() != "")
str += " and FReqDate <= " + ConstList.DateStoM(Ttimet.Text.Trim()).Date.ToShortDateString();

return temp.retpricereq(u2, str).ToString();
//return "1";

dont use static
JoCodes 3-Oct-13 13:36pm
IS your method in your codebhind page?
JoCodes 3-Oct-13 13:31pm
static funtion was to make the function access like '<%# %>'
saeed1364 3-Oct-13 13:35pm
when use static dont know Eval("FUserId").ToString());
saeed1364 3-Oct-13 13:37pm
Error 4 An object reference is required for the non-static field, method, or property 'System.Web.UI.TemplateControl.Eval(string)'
JoCodes 3-Oct-13 13:43pm
Eval wont work since its non statc . check the below comment which includes a link how to use non static methods with Eval
JoCodes 3-Oct-13 13:40pm
Can you check this if you want to use Eval ..
