            }
            catch (Exception ex)
            {
                ClientScript.RegisterStartupScript(this.GetType(), "Popup", "ShowPopup('" + CommonFunction.ErrorMessage + "');", true);

Hi JagjitSingh ,

Static method belongs to class level , it is called through the class. "This"  refers to current instance of the class. Static method of class is prior to instance of the class ,so you couldn't visit "this" in your static method.

Please refer to https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/static to learn more about static.

You could change it to instance method.

hi

here  you have many mistakes, 

first ClientScript is available for classes that derived from Page Class for example

 public partial class WebForm1 : System.Web.UI.Page

  now in Webform1, you access to ClientScript

second, you define a property that returns a string and the ClientScript not run any time

I suggest you return a string in your property and then put the result in a ClientScript in your context
