VS 2012 Update 2 - precompiling ASP.NET 3.5 site problems

June 6, 2013, 11:40 am

Hi, hoping someone has a solution to this one....

I have an ASP.Net 3.5 site that has had no problems with precompiling on VS 2005, 2008 and 2012, however precompiling after Update 2 for 2012 just won't work - VS2012 goes through the motions, files are created, but those files, when copied to the live environment kick up the dreaded 'sys is undefined' error.

A colleague who hasn't installed the update can precompile the exact same solution, without any errors being created.

I realise Update 2 has introduced more control over the publish process, but I'm obviously missing some setting that is automatically included pre-update2.

Help!

AsyncFileUpload control not showing proper error message

June 7, 2013, 1:10 am

Hello,

I have below code for AsyncFileUpload control in one page.

<asp:UpdatePanel ID="UpdatePanel1" runat="server"><ContentTemplate><cc1:asyncfileupload onclientuploaderror="uploadError" onclientuploadcomplete="uploadComplete"
                        runat="server" id="AsyncFileUpload1" width="242px" completebackcolor="White"
                        uploadingbackcolor="#CCFFFF" throbberid="imgLoader" onuploadedcomplete="FileUploadComplete"
                        uploaderstyle="Modern" clientidmode="AutoID" />&nbsp;<asp:Image ID="imgLoader" runat="server" ImageUrl="~/Images/ColumnProgress.gif" Style="margin-bottom: 0px" /><br /><asp:Label ID="Label1" runat="server" CssClass="Errortext" Text = ""  /></ContentTemplate></asp:UpdatePanel>

Below is the script code to generate the error message.

<script type="text/javascript">
        function uploadComplete(sender) {
            debugger;$get("<%=Label1.ClientID%>").style.color = "green";$get("<%=Label1.ClientID%>").innerHTML = "File Uploaded Successfully";
            document.getElementById("Label1").innerHTML = "error";
           // window.opener.location.href = window.opener.location.href;
           // window.opener.location.reload(true);
            //window.close();
        }
        function uploadError(sender, args) {
            debugger;$get("<%=Label1.ClientID%>").style.color = "red";
          //$get("<%=Label1.ClientID%>").innerHTML = "File upload failed. Please check file format or size.";$get("<%=Label1.ClientID%>").innerHTML = args._errorMessage.replace("Server Response Error: ", "");
        }

Now, I know that whenever we throw an exception from the code behind with proper error message, ajax control will ask for that annoying error popup. 'Do you want to see response page' .. I wanted to skip that. So I wrote below code in Global.ascx file to supress the error response.

  protected void Application_Error()
        {
            Exception ex = Server.GetLastError();
            if (ex.InnerException != null && Request.Url.Query.Contains("AsyncFileUpload1"))
            {
                // This error is generated by a AsyncFileUpload postback.
                Response.Close();   // Close the response
            }
        }

It is not giving me that error pop up, but everytime shows below error message instead of my custom error message which is thrown by exception.

Error Message  :  The requested file uploading problem.

Can anyone please help me to show my custom error message?

Cannot get result from AJAX

I have a file called "index.aspx" and part of the code is as follows:

var ServerTime = {
	        get: function(){
		        var ServerTime = "nothing here";
                $.ajax({
                  type: "POST",
                  url: "Index.aspx.cs/getServerTime",
                  data: "{}",
                  contentType: "application/json; charset=utf-8",
                  dataType: "json",
                  success: function(msg) {
                    ServerTime = msg.d;
                  }
                });
		        return ServerTime;
	        }
        }

 

The above code will call the method "getServerTime" in my "Index.aspx.cs" file.

        [System.Web.Services.WebMethod]
        public static string getServerTime(string DateTimeFormat)
        {
            if (DateTimeFormat == null)
            {
                DateTimeFormat = "HHmm";
            }


            String message = "nothing";

            try
            {

                message = DateTime.Now.ToString(DateTimeFormat);


            }
            catch (Exception err)
            {
                message = "Exception found: " + err;
            }


            return message;
        }

The strange things is that when I called the following code:

onsole.log(" Time Server: " + ServerTime.get());

I get the following result, which is not what I expected

Time Server: nothing here

Is there something wrong with my code?

AJAX Extensions undefined on open aspx page after upgrade to VS2012 on Win 7 64bit

January 1, 2013, 2:51 pm
$

Hi:

We recently upgraded our development boxes from VS2010 on Win 7 32 bit to VS2012 Win 7 64bit. On every legacy Net 4.0 webform solution since the upgrade, we now have the exact same problem on every box. If we open any aspx page, and modify the aspx code, every Asp.net extension (scriptmanager, updatepanel, timer etc.) becomes undefined in the designer page - however only on the open page - all other pages that are unmodified and closed are OK.

Example: Type 'System.Web.UI.WebControls.UpdatePanel' is not defined.

If we remove 'System.Web.UI.WebControls' from the control in the designer page, the error goes away. However, if we drag and drop a new UpdatePanel or other AJAX extension control onto the page, it is still shown as System.Web.UI.WebControls.XXXXX and an error appears in the designer.aspx file.

1. System.Web.Extensions is referenced, and it is the 4.0 dll.

2. targetFramework="4.0" is set in the web.config.

3. The compile target is 4.0.

4. Net 4.0 is installed and so is the 4.0 AjaxToolkit and the Extensions.

We have tried;

1. Dragging and dropping a new extension control, such as an update panel on the page and clean and recompile. Does not change the error.

2. Changing the build target to 3.5 and then changing back to 4.0.

3. Getting a stronger coffee.

Nothing works and we are at a standstill. Can anyone suggest a cure?

Thanks in advance,

Bill

ModalPopupExtender with panel visible and called programmatically

June 12, 2013, 1:06 am
$

Hi!

I am wondering if there is a way that I can have the panel that I am using in the modal popup extender be visible in the natural order of the page.

Basically I have a simple email signup form, at the bottom of a fairly long page, in a panel, I want that panel to be there at the bottom, visible and be accessible to the user. Then when they submit, I do validation with a ReCaptcha as well as asp.net regex validation (confirm an email asd@asd.asd). But if there is an error, rather than reloading the page and the user being clueless as to why the page just loaded, I want to call that same panel in a modal popup and let them correct their errors, rinse and repeat until the email is good and the recaptcha is good. Then after success the panel should be in place in the page again without the modal popup

From what I can see as soon as you associate a panel with a modal popup extender, it makes it invisible and I dont see any options in the control to force it to be visible. Any thoughts? Do I need to make 2 seperate panels and turn up the spaghetti?

Also another small issue: I tried using an imagebutton to load the panel in the popup, which works fine, but it is forcing my validation to fire off before the input elements have been filled out by the user. Is there something I need to change to make that popup not push validation? Currently I use in the C# code if (Page.IsValid) {} to check the ReCaptcha, so do I need to make this OnPostBack or something?

Thanks a ton!
