Javascript - Failing To Catch Server Error In Sharepoint?

Nov 4, 2010

I have an control that contains a grid view sitting on top of an Ajax update panel. The control has been added to a sharepoint page. When a button is clicked, some server code is called to store the contents of the grid. If the server code throws an error, I want to spit out a javascript alert displaying the error message, but for some reason the error that bubbles up from the server is the generic 500 server error, which doesn't contain any details of the original error.

DataSource Controls :: Catch Don't Catch Any Error From SQL 2000 Transition Store Procedure

Here is the code copied from [URL] In code behind, I use try-catch try to catch any error but never catch it. In SQL database, if I rename Employees to Employeesx or change column DepartmentID to DepartmentIDx, record will not be deleted (it is right) without any error (it is wrong, suppose catch an error).

DataSource Controls :: Error Accessing SQL Server Db From User Control In SharePoint

Jan 15, 2010

I'm developing an ASP.NET user control in VS2008 that writes to a SQL Server 2005 database. I've published the control to a SharePoint 2007 MOSS page using the SmartPart addon. The control consists of a few text fields and a submit button that writes the contents of the text fields to the database. When I test the control in the Visual Studio debugger, it works fine. When I try to submit data from the SharePoint page, I get the error shown at the end of this post. Last time I saw this, it was a database permissions error, but I've granted my site's default application pool read/write access to my database. Does anyone have any idea what else the problem might be? Also, how can I double-check the credentials that the SharePoint page is using to access the database, since I still suspect that this is a permissions issue?

C# - JavaScript: How To Surround An Auto Generated JavaScript Block With Try/catch Statement

Jan 17, 2011

In the Script documents that automatically generates how can I surround the whole generated scripts with try/catch statement to avoid 'Microsoft JScript Compilation error'

My issue is: i got a DevExpress control (ASPxGridView) that added and set-up in run time, since i activated the grouping functionality in the grid I still get JS error says ';' expected whenever i use (click) on one of grouping/sorting abilities, I activated script Debugging for IE, in the JS code turns out that there is no missing ';' and once i click ignore for the error msg that VS generates every thing works fine, and surly end-user can't see this msg so i figured out if i try/catch the script that may help avoid this error.

Sharepoint2010 - Sharepoint + Website - Encountering "A Page Can Have Only One Server - Side Form Tag" Error

Apr 21, 2010

I have an ASP.NET Web Site hosted in the _layouts folder of a SP2010 site. One of the pages contains a server-side form and works fine until I try to set its master page to a Sharepoint master page (specifically a modified v4.master) to achieve a consistent look & feel. I've placed my original page content within <asp:content> tags but it now throws an "A page can have only one server-side Form tag" error. I know that ASP.NET pages can only contain a single server-side form but what walkarounds can I use to stop Sharepoint from throwing this error?

JQuery Ajax Call Failing With Undefined Error

Jun 5, 2010

My jQuery ajax call is failing with an undefined error. My js code looks like this:


My ajax source is a generic ASP.NET handler:


Now, if I return an empty object ("{ }") in my handler, the call will succeed. But when I return any other JSON object, the call fails.

The dataFilter handler shows that I am receiving a correct object. Firebug shows the response as expected, and the JSON tab shows that the object is parsed correctly.

So what could be the cause?

[Edit] I should have actually written "when I return any invalid JSON object, the call fails"! :D

In MOSS 2007, we could update the tag's callstack attribute to true and then customerrors mode to "Off" to see the actual error behind the 'An unexpected error has occurred' message. Does it apply on SharePoint 2010 as well ? I tried it but I get the following error:

Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.

MVC :: RC JQuery $.ajax Requests Failing / He Error Code Is 12030 Or 12031

Jan 14, 2010

Yesterday I upgraded to MVC 2 RC. I have several jquery ajax requests that worked fine prior to the upgrade. Sometimes they work, sometimes they don't.

I know the MVC team made changes to the framework to protect against Json Hijacking so that GET requests are not allowed (by default) and I have changed my jquery ajax code to use 'type: "POST",' and then adorned the Action Method with the POST verb.

Again, the odd thing about this is that it works sometimes and other times it doesn't. When it fails, there are no error details. The error code is 12030 or 12031.

Web Forms :: Try / Catch Block Won't Write Javascript?

Jun 10, 2010

Since everyone yells at me that MessageBox doesn't work when the project is uploaded to the server, I need to migrate to javascript alert box. As I was changing my MessageBoxes, I tested and found that they weren't being produced. I'm not sure if it matters, but they are in a try/catch block, which is shown here:[Code]....

This all worked before when I had MessageBox - it showed, then the page redirected when I clicked Ok.

I either don't understand how try/catch works, the javascript isn't adding, or Response.Redirect is executed before I can see the alert box and click Ok on it.

(just as a note, everything works fine, but the alert box doesn't show)........if I add the (javascript) code before the try block, the alert box comes up, so it's not something wrong with the writing of the javascript or executing it at least (I think).
