AJAX :: Show A Callout On Page_load Or Control Enter?

Feb 21, 2011

now the task is to show a popup window, much like the standard Windows login panel, to warn the user that caps lock is on. I've used a ValidatorCalloutExtender alongside other controls in my site, but can't figure out how to use the test for whether the capslock is on:

[Code]....

to then show a callout style display. I'd prefer it only pop up when the user enter's the asp:textbox control, but can't figure out if a callout is possible in this way.

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

Feb 7, 2010

Here is the code copied from [URL] In asp.net 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).

CREATE PROCEDURE DeleteDepartment
(
@DepartmentID int
)
AS
BEGIN TRANSACTION
DELETE FROM Employees
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END
DELETE FROM Departments
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END

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.

Source Error:

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.

Stack Trace:

[ThreadAbortException: Thread was being aborted.]
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +486
System.Web.ApplicationStepManager.ResumeSteps(Exception error) +501
System.Web.HttpApplication.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData) +123
System.Web.HttpRuntime.ProcessRequestInternal(HttpWorkerRequest wr) +379

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.

Web Forms :: How To Tell Try Catch To Not Log Into Event Log

Sep 27, 2010

I have a property call (add user to a group) that would be hard to write code to check if user is already in group and I need to call it multiple times sometimes for the same group. anyhow it throws an error if user is already in group. easy way if to just put in a try catch and do nothing for the catch. it works fine except there are several errors in the application event log for this error when it happens. I would rather it not to log this error as it takes up time when looking in the event log to say - this is not a valid error log. so is there a way to tell a try catch to not log in the event log an error it is catching? I would rather not change any settings for the whole site but perhaps just this 1 page might be acceptable.

Web Forms :: When And Where To Write Try Catch Block

Mar 31, 2010

When to write try catch block?

Should I write it for each method or only in event handlers or ????

What happens when an exception occurrs? What is the stack for exception?

If I use it at entry point (event handlers) then how do I get actually at which line error occurred?

Suppose an exception was thrown from Data Access Layer How do I get it in presentation layer that exactly in which class method at which line why that error occurred?

Is it true that excessive use of try catch makes application slow?

Web Forms :: Loop Inside Try - Catch Block?

Apr 29, 2010

Can somebody show me a better approach of looping through a Try -Catch statement. I have something like this:

Try
dbConn.Open()
Catch ex As Exception
errmsg = ex.Message
End Try

I need to try to connect 5 times before logging an error. My first thought was to nest Try - Catch 5 levels but I didn't like that idea. I'm sure there is better solution to it.

Web Forms :: File Not Found Error - Try / Catch?

Sep 7, 2010

I come from a VB environment. I'm looking at 2 different file extensions. If one doesn't exist look at the next. I was hoping to use the try/catch function. I can get it to find the first extension but not the second. Here is my the try/catch part of code:

try
{
string website = xAll;
Response.Redirect(website);
}
catch (FileNotFoundException)
{
string website1 = xAll1;
Response.Redirect(website1);
}

The error dialog that pops up shows Connection Error in the title and a yellow exclamation point with File Not Found! I thought the FileNotFoundException would work(?).

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).

Web Forms :: Page_Load Not Being Called?

Jan 19, 2011

Please have a look at my VB/ASP code and tell me if you can see what's wrong (I have bolded the important segments):

[code]...

Basically, I'm trying to get the Page_Load subroutine to execute on the page load, but it doesn't seem to be called. I'm assuming that because I set my feedback label to "feedback" in the Page_Load subroutine, I should see it displayed on the page saying"feedback" on first loading the page and every time I refresh. But this doesn't happen. I'm lead to conclude that the Page_Load subroutine is not being called on the page load.

Web Forms :: Catch Click From Link Inside Widget?

Aug 29, 2010

I have an ASP.NET (3.5) page. On the page there is a widget. Here is the page code:

[Code]....

The widget (script) displays a list of news from another website like this:

---------------------------------------------------------
title1 (as link)
short description
title2
short description
.............................................
---------------------------------------------------------

1. When a user clicks on one of the links in the above list I want to "catch" the link.

2. ISSUE: When the link (from the list) is clicked the URL is opened in another browser tab

3. If a user clicks on a link I want to redirect him not to the link's URL but to a page of my website.

I have tried using global.asax (application_beginrequest) but, since the link is opened in another tab that function is never reached. How to do this?
