How to display a msg or alert box above those images. Please help me out. my code for alert box is as follows:

void CallToast(String msg, String cls)
    {
       System.Text.StringBuilder sb = new System.Text.StringBuilder();
       sb.Append("<script language='javascript'>");
       sb.Append("toast("+"" + msg + ""+","+"" + cls + ""+");");
       sb.Append("</script>");

              CallToast("Sorry! Please try again", "toast-error");
          }
          else
          {

          }
       }
       catch (Exception ex) { }
   }

推荐答案

ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('Your request for change in  code has been sent to Nasa');", true);

尝试这个简单的代码

try this simple code

你必须更改代码

you have to change the code

sb.Append("toast("+"" + msg + ""+","+"" + cls + ""+");");

to

to

sb.Append("alert("+"\"" + msg + ""+","+"" + cls + "\""+");");
