View 1 RepliesForms Data Controls :: (event Handler) To Clear Everything Behind DetailsView In Insert Mode
Jun 16, 2010A DetailsView in Insert mode has all fields cleared after events such as the following:
1. Clicking New.
2. Clicking Cancel.
3. Clicking Insert (if the default mode is Insert).
I have some fields linked to ViewState and they are populatd at PreRender event handler. I am wondring if there is a single place where all relevant ViewState elements can be cleared instead of doing this in all possible relevant handlers such as ItemCreated, ItemCanceled, ItemInserted, etc.

Difference Between Adding Code In The PreLoad Event Handler And At The Top Of The Load Event Handler?
Oct 3, 2010Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?
View 2 RepliesCannot Set Textbox Value In Callback Handler In C#
Mar 16, 2010I am using ASP.NET Callbacks (that implements the ICallbackEventHandler) and in the handler, I try to set a value of the text box:
txtName.text = "Test";
but this value is not set. Is this a limitation with callback? It appears I cannot do much in a callback handler other than sending back a string to the client side (ofcourse I can access the Session etc)

Apr 24, 2010Using vb.net/asp.net 2005.
I have a page books.aspx that has a control named authors.ascx.

Web Forms :: Event Handler Used In BLL When Building A PlaceHolder
Mar 3, 2010My goal is to move as much code from the code behind page to the business logic layer. I'm having trouble with an event handler because the code can't see the method it will call (because the method is on the code behind page and the code in question is in a class in the BLL). CS0103: The name 'ButtonClick' does not exist in the current context (the error) b.Click += new EventHandler(ButtonClick); (the line)
Right now I'm considering to try it by adding the EventHandler from the code behind page after the PlaceHolder has been sent to the code behind page, but I'm wondering if I'm missing a better way. Is there a best practice for how to deal with this? Do I throw in the towel and just let the PlaceHolder be built on the code behind page (where it works fine)?
Web Forms :: Event Handler For LinkButton Is Not Called
May 26, 2010I have LinkButton as the submit button in the web page. The problem I am facing is it is not calling servr side event handler.
The js function for 'onclientclick' is returning true but the method mapped to 'onclick' is not being called.
I tried putting alert message in onsubmit event also, that is also coming.
How to diagonise the issue? What are the possible reasons for this?

Web Forms :: Rewiring Up Event Handler Of User Control?
Jul 16, 2010I have a web page where I'm dynamically loading one of a series of user controls. In each user control I call a general-purpose event to inform the web page that data on the user control has changed and/or new data is available. On the user control I define the Event Handler like this: public override event EventHandler DataOut_Handler; and then I force the event to occur like this:
DataOut_Handler(sender, e); On the web page I reload the previously loaded user control and wire up the event handler like this:
protected void Page_Init(object sender, EventArgs e)
{
DataEntryUserControlBase userControl = (DataEntryUserControlBase)LoadUserControl();
if (userControl != null)
userControl.DataOut_Handler += new EventHandler(UserControl_DataOut_Handler);
}
Note: It's "DataEntryUserControlBase" rather than "UserControl" because I constructed an intermediary base class to making casting simpler. Everything seems to work fine but I do have a question: When I step through my code, after the last line in Page_Init is executed I move the mouse cursor over top of userControl.DataOut_Handler but it reads null. The code is working fine but I'm most curious why I don't see any object associated with that item immediately after wiring up the event handler?

Web Forms :: Event Handler Not Subscribed To Content Page
Jan 6, 2011I have a master page that contains a navigational menu, made up of nested databound repeaters. Buttons are created for the outer-most repeater's items. When the user clicks on one of these buttons, the content page loads and a label within this content page changes to reflect the text from the button that was clicked. In other words - click a button, load the page, change the label on the page to the text on the button. I have tried also changing the initialization on the content page from Page_Load to Page_PreInit to Page_Init, and nothing seems to matter as I'd like to move on in this project! Code follows:
Master Page (Site.Master):
[Code]....
Content Page (BatchView.aspx):
[Code]....
The problem is, whenever a button is clicked, it changes the title of the master page to 'Not Working', which lets me know that the TeamChosen eventhandler is null!
