I have a page with formview, the page contains a lot of input fields and a lot of validators and when I press "Save" button (in which I perform insert procedure) the form is validated, but button click event and page load happens. Validators and button belong to the same validation group. How to avoid button click and page load events happening when some validators aren't correct? In page without formview everything works ok, I click "Save" button and when all validators are correct only then happens button click event. How to fix that with form view?

ValidationGroup="req" runat="server" AutoPostBack="true">
validations summary: button save: OnClick="ButtonSave_Click" TabIndex="6" />
how to validate this in the button save also two popup box should be shown
I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards.

Is there a way to control gridview sorting by using a dropdown box rather than than just clicking the headers of a column? Any pointers in the right direction

when i use it on a empty webform it works nicely, however when i use it in a ListViews InsertItemTemplate it does not.get an error aying document.GetElementById is null and stops elowdocument.getElementById("CheckBoxListStr_0").checked = false
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?

I have a search page. Based on the user that is logged in, a link will display if they have saved any previous search criteria. If you have any, the link will open a modalpopup with a list of all your saved searches. I have it setup so when you select the search you want to perform, it will take those values and populate the search form for you. What i would like to do is if you select something from the list, after the fields are populated(which is already working) i would like that searches button event to be executed so the search values are passed in and the results are shown instead of having them press the search button again.
I tried adding this to my select event but thats not correct i know.. so is it possible to execute another buttons event?

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).

Background:
I am setting up an intranet site (ASP .NET) where users from our local user group (who are also added in our user table) will have access to web applications they are given access to. Right now I am developing from my PC and using SQL Server 2005 Express as the database, but the final site will be hosted on an application server with IIS 6.0 and the database on an instance of SQL Server 2005. I am a .NET newbie and it's a daunting task, but the experience is worth a million dollars.
Details:
We are using Windows Athentication for our intranet site. Therefore I am not using ASP .NET's membership data sources. Rather all the user information will be stored in two tables tblEmployee (all employees in my company) and tblUser (all users of the intranet site).
tblEmployee has fields - EmployeeID, FirstName, LastName, CostCentre, Role, ManagerName, UserID
tblUser has fields - EmoployeeID, UserID, ApplicationID, AccessLevel, AddedBy, DateAdded
(I have set up these tables and I can change them any time).
What I need to accomplish - When an user goes to the intranet site, I can get his/her domain username. I need to check if this user exists in tblUser (domain username is same as UserID in tblUser). If user exists, we display all the applications he/she has access to, else display a "no access" page.
Specific questions:
What are some of the things I need to "learn"? (as I said before, I am a .NET newbie, but a fast learner too) I need to use URLAuthorizationModule for validating a page request. How do I hide the username from the URL? I was thinking along the lines of using a session ID... but then how do I know who the user is? I am sure these is a way to encrypt the UserID, just can't find it.
I realize that this question can start a discussion but that's really not my intention. We've created a Flex Application to take tests from candidates. The advantage of the Flex Application is that all state can be stored in the application running in the browser of the client. Things like time limits, navigation, scoring, ... can all be handled within the application without us having to worry about a back button for instance. Even running the app offline with Adobe Air isn't that hard.My question now is if such an application could easily be made with HTML, Javascript, Ajax, ... ? The reason I'm asking is because an application in HTML would be much easier to distribute on Mobile devices for instance. Also, our domain model for instance is mostly implemented in AS3 (Flex) so using it along the server side means porting it to C#.NET. (with two codebases as a result).

View 3 RepliesI have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.

View 1 RepliesI have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.

View 2 RepliesI am working on an ASP.NET web application, we are a small team (4 students) and we do not have access to a dedicated server to host the database instance. So for this web application we decided just to put the database file in the App_Data folder.
The problem is that our project is source controled on TFS, so every time you open the solution and try to launch the web application, we get an expcetion saying that database is read-only. That is logical because the databse file is not automatically checked-out.
