On a check box check changed I want to test some conditions and based on that I want to display a confirmation message. Based on the user action, OK or Cancel I want to proceed or stop the process. How can I do that. I tried this,
Even I click Cancel the rest of the code also executed. How can I handle this?
All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:
So how can i just return ViewData["SqlError"] message in page.
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.

I need some jquery code in my application I have a button on the page and I want to handle it by jquery when the user click on it to show a confirmation dialog for example Are you sure? yes|no buttons but this is an asp.net button inside the updatepanel and in the other side I have some server side code to delete a record from database but my question is how I can handle both of them? server side and jquery inorder to when "yes" button clicked it runs server side and delete recorde from database and if the button is no it stop running ?
I have a customvalidator to validate the sum of 2 drop downs.. the validation code is working, because if the sum doesnt match my logic the page is not submitted, but if i select values that match my logic, the page is submitted.. so i know the logic is working, but the error message is not working.. and not sure why..
Some background, last week i had this working based on additional controls, but the business decided they wanted less questions on the form, so all i did was remove the controls from the validation and updated the logic to make sure it was only calculating against the existing controls. reminder that the validation is working( meaning that the page is not being submitted because it failed ) but the error message doesnt display on the page, so no one knows what is happening..
i ahve one custvalidator control in that i have used OnServerValidate="ValidateDateRange" ValidateDateRange is function i have written in serverside now i want raise error message without postback operation like (clientside validation) if that ValidateDateRange function returns false .
I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here?
I have textboxs that define requiredfield validator for them..I want when I click on button if users don't type text in textbox it shows popupmenu some thing like ModalPopupExtender that I can define div on it and it shows just this text" please fill required field".
