Callback Functions For Server-side Controls
Mar 27, 2012
I have an ASP.NET control (a button) in a WebApp. It has an onclick attribute:
onclick="SaveButton_Click"
SaveButton_Click()
is a C# function in the codebehind file. When the user clicks the button, SaveButton_Click() is executed.
What I would like to know is whether there's a way to set up a javascript callback junction. I know how this is done in AJAX, but I'm not sure in ASP.NET (with controls that run on the server) how (or if) this can be done.

Is there a way to run server side functions by javascript? There are two things I need to do:
1. Either emulate clicking a link/button, or calling the OnClick function directly (not OnClientClick)
2. Control the back and forward control of the wizard control by using the keyboard

I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...

HOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.

I have my app running on asp.net 4.0 and IIS 5.1.
I'm having problems running IO functions on my PUBLISHED website, on the server running IIS. I can run everything just fine on my own machine without any issues in debug mode.
I pinpointed the errors to some IO functions Im trying to add.
Example:
StreamWriter sw = new StreamWriter(outputfile, true);
sw.WriteLine(DateTime.Now.Date.ToString());
or
File.Copy(sourceFile, destinationFile), true);
When I add something of this nature.. I get the generic runtime error (since I'm not sure how to make it show more specific errors at this point)
I was thinking it has something to do with a security issue. But, Im not sure where to look.

I have a user control in the sidebar(in my web site) for display title and picture of any of news. his usercontrol in all of the pages is observable. when user click on the picture navigate to the page News.aspx for more details. first time i can but in second time when i click on another picture in the News.aspx i get an error like below:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. but when i reload the page the problem is solved my code is:
[Code]....
and my page directives is
[Code]....

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
