Web Forms :: How To Detect Which Control Caused A Postback
Dec 16, 2010Is there a way to determine which control on a page caused a post back? I need to be able to make the determination since the _DataBound event of a FormView that I'm working with needs function differently based on which control caused the postback.

View 5 RepliesRedirect - Identify The Postback From Login Control?
Oct 6, 2010I have a <asp:Wizard> that is only applicable for a logged-out user. If the user is currently logged in, he/she is redirected to another page. On one of the wizard steps, as part of the wizard, I ask for credentials via the <asp:Login> control and log in the user. This presents a problem.
According to MSDN: "When a user uses the Login control to log in to a Web site, all data in the view state and all post data is lost. Do not perform actions in the LoggedIn event that rely on the view state."
Because of this, my Wizard control forgets the step it's on after the login process. MSDN recommends: "If you embed the Login control in a WizardStep object, explicitly set the ActiveStepIndex property in a Page_Load event handler if the user is authenticated. The Wizard control does not automatically advance to the next WizardStep object in this scenario."
However, because all view state is lost, the redirect for logged-in users kicks in, sending the user away from the page. What's the best way to determine, at page load, which of the states the user is in?
Already logged in some time ago; needs to be redirected. Was just logged in from inside the wizard; needs to reach the next wizard step.
MVC :: How To Determine Which Event Caused The Postback
May 13, 2010Currently I have two events in my view that can trigger the post back (A dropdownlist and a submit button).
1. <%= Html.DropDownList("List", ViewData["Days"] as SelectList, "--Choose Day--", new { onchange = "this.form.submit();" })%>
2. <input type="submit" value="Submit"/>
When either of these are used, it they both call the [AcceptVerbs(HttpVerbs.Post)] Index() method.
What I want to know is how can I know which event caused the postback, because I need to process each one differently.

View 2 RepliesDetermine Which Control In Window.onbeforeunload In Javascript Caused Event
Mar 7, 2011I have set up in javascript:

{
if(window.event){
if(!onBeforeUnloadFired) {
onBeforeUnloadFired = true;
window.event.returnValue = 'You will lose any unsaved changes!'; //IE

windows.setTimeout("ResetOnBeforeUnloadFired()", 1000);

//Need this variable to prevent IE firing twice.
onBeforeUnloadFired = false;
}
I'm trying to achieve an edit screen where the user is warned before navigating away. It works fine except I get the pop up for normal post backs of button clicks. I'm hoping to avoid this so I'm figuring if I could determine which button was pressed it would work. Does anybody know how to determine which button was pressed in the indows.onbeforeunload? Alternatively anyone know a better approach to what I'm trying to achieve?
C# - Identify Callback Control Id?
Oct 26, 2010I have a masterpage that contains a user control. The usercontrol uses callbacks for various operations. However, every time a callback is issued from the user control it is propagated down to the pages that inherit from the master page. How do I determine the id of the control that issued the callback so that I can stop these callbacks from destroying the state of the pages?

Setting the panel's visibility to false gives me all sorts of issues and I don't know where to go now to get rid of this annoying space!

Configuration :: AllowDefinition='MachineToApplication' Beyond Application Level. Error Can Be Caused By A Virtua
Mar 11, 2010I am using VS 2008, IIS 7, .NET 3.5 on a vista machine. I created a new web-site using "HTTP", thus to use IIS. The application being created by VS 2008 created the virtual directory.
There are only two objects created initially with a new website "Default.aspx" and "web.config" file. I've made no changes and choose to view in browser and receive the following error:
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
I've removed and reinstalled IIS 7. None of the sites previously created work. I've validated that a duplicate webconfig doesn't exist.

My problem is I can't use the SelectedIndex to identify the Access Row because when the user uses paging/sorting the SelectedIndex is not the AccessRow. Somehow I have to identify the selected row the user chooses with the PrimaryKey in Access ("Number").
