I need to generate some controls dynamically.So i code as belows:
using System;
using System.Web;
...
namespace MyProject
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
TableRow row = new TableRow();
TableCell cell = new TableCell();
Button btn = new Button();
btn.ID = "btnCreated";
cell.Controls.Add(btn);
row.Cells.Add(cell);
this.Table1.Rows.Add(row);
btn.Click += btn_Click;
}
protected void btn_Click(object sender, EventArgs e)
{
this.TextBox1.Text = "test";
}
}
...
when i run it,the table(include the new button) can be show after i click the button1 .But when i click the new button(ID as btnCreated),it doesnt work.And the worse is the created table disappears after i click the new button.
How to solve it??

Dynamically added control have to be added each time the page is posted back
I think you must add them in the preinit event
Try that and see what happens

thank you,I tried adding code in Preinit event,it really worked.
I still have some question,I need to add control by clicking the assigned button,but if i add this code in preinit event,it always add control whenever any button clicked.If i got 2 or more buttons on the page ,how to identify which button cause the adding event?
The second is,how to save the dynamically added control's property (for example:textbox) ,if i change the text of the textbox,after page posted,the dynamically added control re-builded,how can i get the changed text.

Hi,
I currently have a site and I do have an SSL key, but I am not forcing the main page to be run in SSL. However, this main page has a few options that anonymous users can use as well as a login/password text box using ASP.NET's built in login functionality.
Is it possible for me to have it so that, when the user enters data into the username/password and submits it, it goes through SSL for the postback here regardless of if they are logging into the site via HTTPS or HTTP? I am trying to avoid forcing the main page to be always run in SSL and I am assuming that if I don't do anything and the user logs in over HTTP, their username/password is sent around in clear text.
Thanks,
Steve

You could always just use a one-way secured crypto hash of the password. Why not just use SSL?

How about a box for the user's username which is on the main HTTP page which then goes to a separate HTTPS page where the user then enters their password which is then encrypted. I've seen banks do this with Internet banking, where the user enters an ID or other insensitive piece of data then they are redirected to an encrypted page to enter the sensitive information like sort code and security number.

Hi,
I have my ASP.NET web application in C:\inetpub\wwwroot\NewsModule
Now in the production server, I need the files to in a News folder in the existing application, but the web.config should be outside this folder. In my application I am using relative path (~) to access user controls and style sheets. But when I uploaded these to production server and created a similar structure, I get the error "HTTP 404 , resource cannot be found"
What am I doing wrong here?
Regards,
Blumen

Can i change the position of the column. and
can i insert the new column in first position if table has been already created
|

Actually there is no good solution for this.
I think that if your application depends on the column order, its better for you to rethink your code. It's almost sure it will give you trouble in the future.
Even though, I think the easiest way to do that is to create a View, with the columns in tha order you want (but not for insert new column in different order...)
Intelligence is almost useless for those who have nothing else!

Perhaps Crystal Report provide property WindowShowPrintBtn . You can set true/false as your requirement.

Add the first group of controls inside a panel and set the panel's defaultbutton to the corresponding button
Do the same for the other group of controls
