Getting Unhandled Exception But Unable To Catch With Try Catch

Sep 14, 2011

I get this error in the browser:

Code:
Thread was being aborted.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Threading.ThreadAbortException: Thread was being aborted.

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053

I have try{}catch(Exception ex){} in the right place:

Code:
protected void Button1_Click(object sender, EventArgs e)
{
try
{
// all processing occurs inside here
}
catch(Exception ex)
{
}
}

I even created a global.asax file and on the Application_Error event, I wrote a code that would email me the error (and i'm not getting an email regarding that error when I get the error shown above). I know for a fact that the thread is going inside the "try" statement because I send emails to myself whenever it finishes certain codes inside of it. So how come I'm getting that error in my browser instead of it being handled in my "catch" statement? I have two problems here, one, why is the exception not going to my "catch" statement, and two, why am I getting that error in the first place.

Note: my web app calls a webservice.

MVC Exception Not Being Caught In Try Catch Block?

Jan 21, 2010

I have tried this on two different controller methods now, and both times, even if the linq2sql doesn't allow the data to be saved, the code never jumps into the catch block.

I've watched the noun object in the middle of the trace, and the isvalid property is false, but the modelstate isvalid is true. Either way, the code never jumps into the catch block.I'm pulling my hair out about this. I feel like it will be something really silly.

The code all works similar to nerd dinner.

NounRepository nounRepository = new NounRepository();
Noun noun = new Noun();
try[code]...

I'd rather not have to add code in this manner though, as it seems like an unnecessary duplication.

C# - How To Catch Exception Occurred In DAL Of ObjectDataSource Object

Sep 1, 2010

I have ObjectDataSource and GridView on one of the pages of my asp.net web project.

To initialize ObjectDataSource i use Init event:

protected void ObjectDataSource1_Init(object sender, EventArgs e)
{
ObjectDataSource1.EnablePaging = true;
ObjectDataSource1.TypeName = "CustomerDataSource";
ObjectDataSource1.DataObjectTypeName = "Customer";
ObjectDataSource1.SelectMethod = "GetCustomers";
ObjectDataSource1.UpdateMethod = "Update";
ObjectDataSource1.SelectCountMethod = "GetCustomersCount";
ObjectDataSource1.MaximumRowsParameterName = "maximumRows";
ObjectDataSource1.StartRowIndexParameterName = "startRowIndex";
}

Somewhere in DAL:

public static List<Customer> GetCustomers(int maximumRows, int startRowIndex)
{
try {
... some select to database here...
}
catch (Exception ex)
{
Utils.LogError(ex);
throw ex;
}
}

Now let's imagine that GetCustomers for some reason throws an exception. How could i catch this exception and handle it? I know i can use Application_Error, but i would like to catch this exception somehow on my page and show some friendly message to the user.

Event Causing Error But Can't Catch Exception

Apr 22, 2010

A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line.

Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound
Try
ProcessBadData...
Catch ex As Exception
Throw ex
End Try
End Sub

In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. how I can capture the exception in this ASCX control so I can report it to the user? Edit: The stack trace looks like this. There is another repeater within the repeater that is actually causing the error (rptOther) and I'm able to catch the error, but I can only throw it to the rpt_ItemDataBound. I can't figure out how rpt_ItemDataBound is getting called without a DataBind event.

at Company.WebForms.Control.rptOther_ItemDataBound(Object sender, RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.OnItemDataBound(RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.CreateItem(Int32 itemIndex, ListItemType itemType, Boolean dataBind, Object dataItem)
at System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource)
at System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e)
at System.Web.UI.WebControls.Repeater.DataBind()
at Company.WebForms.Control.rpt_ItemDataBound(Object sender, RepeaterItemEventArgs e)

State Management :: How To Catch Session Timeout Exception

Jun 25, 2010

I need to create a small web application. The first thing I need to do is to develop the login, logout and user session management functionality. I wanted to use a masterpage and a usercontrol for this purpose. When a user open the page and IS LOGGED IN, the usercontrol should something like this:
"Hello Username! <a>Logout</a>"
And if he is NOT LOGGED IN, the Usercontrol should show something like this
"Login | Logout"

When he clicks on the Login Button the Login-page should be opened. How can I build a Usercontrol which does the above thing. (I have never build a usercontrol and used it in a masterpage before!) The second problem is a little bit komplexer: What happens if the user idles some times and after that time (for example 30minutes) comes back to his pc and wants to execute an action in the web application. Normally he should get an session timeout asp.net exception. I don't want that the user sees this asp.net errorpage, I want to redirect him to the Login Page and he should relogin and gets an error message shown something like "You were timed out. Please login again".

C# - ELMAH - Only Sending Specific Exception Type Via Mail

May 31, 2010

I have ELMAH set up for a webapp, logging exceptions to a SQL server. I wish to have ELMAH send me an email too, but only when a specific exception is thrown (ie. MySpecialException). ELMAH must still log all exceptions to SQL server. I know you can do it programmatically in global.asax, but I'd prefer to use web.config. So, how do I restrict ELMAH error mails to filter out everything but a specific exception type, using web.config? UPDATE The filter ended up looking like this:

<test>
<and>
<not>
<is-type binding="Exception" type="MyApp.MySpecialException" />
</not>
<regex binding="FilterSourceType.Name" pattern="mail" caseSensitive="false"/>
