How to code confirm message box after code-behind logic
Hello, all  In a GridView, when the user, after making changes in a row, clicks the Update button, I need to query a database table to determine if I need to display a message box. Basically, I need to inform the user that they are about to change other records as a result of the change they want to make in the currently edited row. And give the user the opportunity to cancel the update. A simple client side return/confirm button won't work, as depending on the particular changes the user makes in the record, the change may or may not cause an update ...

Hi, The web forms designer keeps adding things in a generated InitializeComponent() method.

Using App_Code shared code in page code-behind AND code-front
Hi all, I've only just come across what seems to be the 'correct' way of making use of shared code in my .Net sites: I code some classes in a .cs (in my case - i'm using c#) file. I then put them inside namespaces. To make use of the classes in the code-behind of my web pages, I simply add a "using MyNamespace;" line at the top, and then I can make use of a class' contents like so: "MyClass1.MyString1(SomeVariablesToSend)". Now that works fine when working in the codebehind, but what happens when I want to call the class/string from my code-fron...

Call javascript function from C# code behind using html source code output
I have three tabs on a Main.aspx page(tabs 1, 2, and 3) created using javascript.  When the user leaves the main page and returns to it (if postback) I need the tab selection to remain in session.  In other words, if the user picks tab "2" then leaves that page (but doesn't close the browser) then returns I want that same tab "2" to be active for them.  That way they don't have to reselect the last tab they were on.  How do I call the function from my code behind page using C# ?  here's some of my javascript code I need help with...

what about the code-behind (code behind)
One MAJOR difference between AJAX.NET and Atlas.NET seems to be that AJAX.NET is able to expose methods in your codebehind to the client. Why doesn't Atlas do this? Or am I mistaken? With AJAX.NET it's just a simple line or two:  Ajax.Utility.RegisterTypeForAjax(GetType(myClass)) <Ajax.AjaxMethod()>Public Function myFunction PLEASE tell me Atlas has something comparable to this. I don't have the time to rewrite all my code-behind methods in javascript or atlas script. All you need to do in Atlas to expose a method on your page (or its code behind class) is to put a [WebMet...

Code Behind or not Code Behind
Ok i am confuse now.... A lot of books are showing pages without code behind (the code is integrated in the .aspx) Is it better to use the code behind or not. Is there any difference between using VB.NET or C#.NET except for the code synthax. Thank you and come again. A lot of samples show inline code just for simplicity.. i personally use code-behind because I like to seperate my code from presentation. As for VB.NET or C#, its your preference.. there is no difference really when its all said and done. From a purely mathematical sense, having everything in a single file would s...
