Dim fileName As String = Path.GetFileNameWithoutExtension(Path.GetRandomFileName()) & ".jpg"
bitmap.Save(Server.MapPath("/imgs/12.jpg") & fileName, ImageFormat.Jpeg)
According to your description, as far as I know, execute JS function is after page_load event finish. For more details, you can refer to
ASP.NET Page Life Cycle Overview, this article will introduce the order of event executed. For explain this, I make a sample show how to run JS and page_load!
This result is show that after dynamically create a label control, then add style. If page execute JS before page load, JS will can not find the element! I hope you can understand my meaning, if this reply can not solve your problem, please let me know!

Hi Lexi85,
According to your description, as far as I know, execute JS function is after page_load event finish. For more details, you can refer to ASP.NET Page Life Cycle Overview, this article will introduce the order of event executed. For explain this, I make a sample show how to run JS and page_load!
Here is the sample code:
<head runat="server"> <title></title> <script src="Scripts/jquery-1.10.2.min.js"></script> <script> $(function () { $("#Test").css("color","red"); }); </script> </head> protected void Page_Load(object sender, EventArgs e) { Label myLabel = new Label(); myLabel.Text = "Testing"; myLabel.ID = "Test"; this.Controls.Add(myLabel); }Result:
This result is show that after dynamically create a label control, then add style. If page execute JS before page load, JS will can not find the element! I hope you can understand my meaning, if this reply can not solve your problem, please let me know!
