Self modifying code is very rarely needed in programming.
What is it that you think would be best solved using this?

In this case you have to wite Inline script for this page. Simply create a string and save it as ASPX.
Note that in page directive Codebehind attribute should not be there and do write all the login in
tag

Hi everyone,
I have a situation where I must add ImageButtons dynamically on a page. This I managed to do, but I need them to respond to the Click event and they won't.
Here's a snippet which represents what I'm doing:
public partial class _Default : System.Web.UI.Page
{
ArrayList imagenes = new ArrayList();
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
ImageButton ib3 = new ImageButton();
ib3.ID = "ib3";
ib3.ImageUrl = "Puesta de sol.jpg";
ib3.Click += new ImageClickEventHandler(ImageButton_Click);
ib3.Width = new Unit(100, UnitType.Pixel);
ib3.Height = new Unit(100, UnitType.Pixel);
form1.Controls.Add(ib3);
imagenes.Add(ib3);
Session["Imagenes"] = imagenes;
}
else
{
imagenes = (ArrayList)Session["Imagenes"];
foreach (ImageButton ib in imagenes)
form1.Controls.Add(ib);
}
}
protected void ImageButton_Click(object sender, ImageClickEventArgs e)
{
Page.ClientScript.RegisterStartupScript(GetType(), null, "alert('HEY');", true);
}
}
After clicking on the ImageButton, the page reloads, enters the Else clause, the ImageButton is restored, but it won't enter the Click handler.
Also, I tried setting the handler manually inside the Else clause after the control has been added to the form but it won't enter the handler either.
My guess is this is happening because asp.net is actually assigning the handler, but the call to the handler is simply 'lost' during the restoration of the controls since it appears asp.net expects to fire events for 'static' controls only.
I've checked that when a Click event is fired for a 'static' ImageButton, the execution path goes through the Page_Load first and ends into the handler. That's why i re-create the control in the Else clause in Page_Load.
It's not as important for me to get every delegate for each control restored(which i guess it actually is) and working, as it is getting all of them getting into one handler as expected, since I'll possibly assing all of them the same handler.
Thanks a lot in advance for any help you could provide,
Oxi

Ok, strangely enough, when I set the handler now, after re-creating the controls, its working. I'm sorry, i thought i had tested this yesterday already.
I guess I can go on now.
Nonetheless, I'm still interested in a way of storing and retrieving the delegates just in case i stumble uppon a situation where I actually need to use different event handlers for different controls.
Thanks for your support,
Oxi.

Hello All,
I'm trying to develop an application where, i have a flash file running in an ASPX page and that page contains an aspx save button. I need to capture a portion of the screen(i 've filled a rectangle with color and an image in flash-- this need to be captured) and save that as a jpg file in the server on an aspx button click. Code behind is C#.net.
Can anyone help me.
Regards,
jeeva

You can't do that using ASP.NET. As the graphics is shown on the client computer, you will need a component that runs in the browser that captures the graphics and sends it to the server.
You can't even use a server control to trigger the process, as doing so will cause a postback, and when the browser returns from the postback, the page that you wanted to capture is gone.

Thanx for the reply.
can u figure out a possible solution for this?
i somehow want that portion of the screen to be saved on the server.
(Is it possible with javascript or vbscript).
regards,
jeeva

You can't access the graphics of the client using client script. You need something like an ActiveX component or a Java applet.

That is because you haven't set write permission on the database file for the account running the code.

Right click the mdb file and go to the security tab, make sure the .net worker process has access (write) to it.

I want to show data in comments in excel sheet and worksheet will be created in asp.net
Thanks in Advance

I've been developing with c# and forms and I use the Split Container heavily because it automatically resizes when in full-screen. What is the recommendation with asp.net to accomplish this? What control should I use to lay out the various panels on the screen.
|
|
|
|
|
It's not maybe a question of controls - there are a number of ways of laying out a web page - you might want to have a look at www.csszengarden.com[^] or http://www.alistapart.com/[^].
There are many more things to think about when laying out a web form (e.g. cross browser capability) than when laying out a win form.
Hope that helps.
