View 2 RepliesI have a page that is using the Ajax asynch file uploader. What I would like to have happen is after the file is uploaded I would like to have it displayed in a list on the page. I am looking for a way to fire a callback event when the file upload is complete. Is it possible using the asynch fileupload control?
View 1 RepliesA 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.
I need to provide the json string as response to the request made using webrequst as : [URL] ....
Above request will come from other application using webrequest ...
How to implement the page(aspnet.aspx) which handles the request and gives the json string as response. I know how to made webrequest. I am struggling at server end. How to receive request and give response as json string.
Is 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 RepliesI 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)
I've created a database table with a bunch of links I'm going to use in my program. All seems fine, except for the onClick even handler, which doesn't work as a string. Anyone got an idea how I can set it? There's no constructor for EventHandler accepting a string...

I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I got an event handler like this, in this event, i wanted to call another button click event. How can I do that?

i have two frames in a page. the fist one contains buttons the second one the form. i want to call an event from the second one after clicking a button in the first one ,
View 3 RepliesThis event handler is not responding at all to the click event. On click, the pagination numbers disappear and I'm not able to trace it in the debugger because the event handle doesn't even fire so I have no idea what's going on.

View 4 RepliesI have a Silverlight control on page which has a upload control. the silverlight exposes some events such as
StartUpload() => To start the file upload,
StopUpload() => To stop the file upload if running,
CheckFileStatus() => to check the status of the file upload.
The page has aspx Submit button with onclientclick event and ocClick event.
<asp:Button ID="btn_upload" Text="External Upload" runat="server" OnClientClick="Javascript:StartUpload();"
OnClick="btn_upload_Click" />
When I click on the aspx Submit Button, the file selected in Silverlight control should be uploaded and after the completion of upload, the Server side event should get called.
Found this question on an interview siteGiven the following methods of the ASP .Net Page class, in which of them would you attach an event handler to an event published by a control on the web page?

View 3 RepliesThe code below creating a button control on my page dynamicly.
I would like to add to the control's Click event a new event handler.
How should I do it?
i'm creating the control on Click-event of one of the pre-defined buttons( btnSubmit) on my the page and
not at the Load event of the page:
[Code]....
My 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)?
I 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?
Currently have Main.MasterPage, a MyNewPage.aspx (with master page file) and a use control with buttons. Should I load the events in the MyNewPage.aspx during the Page_load or during the InitializeComponent() ?
Example: MyNewPages.aspx (HTML)
[Code]....
Or Should I do this??

I 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?

I 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!
