Error-Object reference is required for non static field method

Hi Naimish

  I have changed but Ajax part is not getting executed.

Secondly what should i change to pass values to BinData()

StudentDetail Result = bALStudents.GetStudentDetailByLoginID(bALStudents.GetStudentIDByMobile(hdfMobile.Value));

                    BindData(Convert.ToInt32(hdfBookId.Value), Result.LoginCode);

Thanks

Based on the provided script, it seems that you're trying to access the values of hdfBookId and hdfMobile elements in the JavaScript code. However, since those elements are usually server controls in ASP.NET, you need to make sure they have unique ClientID values when rendered on the client-side.

Hi Naimish

   Below is the Script. What should i change

Thanks

You need to access variable like this:

public static void getPopUp()
{
    YourClassName instance = new YourClassName();
    // Access the variables through the instance
    var mobileValue = instance.hdfMobile.Value;
    var bookIdValue = instance.hdfBookId.Value;

    // Your code here
}

Thanks
