I might agree with the first part, but certainly not with the second part of that.

Response.Write in ASP.NET works different than it did in classic ASP. It fires quite late in the life-cycle of a page when used in the markup, and may write to unexpected locations when used in the Code Behind.

I haven't had the need to use Response.Write in ASP.NET for years. Your milleage may vary of course, but it's something to be aware off. Personally, I don't think that using it leads to better or more maintainable applications in the long run. Just my 2 cents....

so if you want to write something from the sql you use the "repetar"?

It all depends on the requirements. You could use a Repeater, a DataList, a GridView, a ListView or any of the other data controls if they suit your needs.

Alternatively, you could loop over your data in code and create new elements on the fly. For example:

Code:

 
Literal literal = new Literal()
literal.Text = someDataFromADatabase;
placeholder1.Controls.Add(literal);

This code creates a new Literal control, populates its Text property and adds the control to a PlaceHolder (which should be defined in the markup or elsewhere in code).

What's your scenario exactly? Any reason why you can't use the data-bound controls?

it be more difficult ,i mean that if i want to post any comment its hard when i try that if pepole press the subject then the body message will open to.
or post a advertisement every 10 post.

Quote:

Literal literal = new Literal()
literal.Text = someDataFromADatabase;
placeholder1.Controls.Add(literal);

i will try it

its not so good,i can only write PlaceHolder1.Controls.Add(lerr)once.
if i try to write it twice is still write it once.
PlaceHolder1.Controls.Add(lerr)
PlaceHolder1.Controls.Add(lerr)
(ler.text="hi")

i got only one hi
"hi"
i want to get "hihi"

It might be the beer I am drinking, but this makes absolutely no sense to me....

PlaceHolder1.Controls.Add(lerr)

i got only one hi

It's because it's the same control. Since it's a reference, it doesn't get duplicated. Either assign hihi to the first Literal, or new up a new one:

Code:

 
Literal literal = new Literal()
literal.Text = "hi";
placeholder1.Controls.Add(literal);
literal = new Literal()
literal.Text = "hi";
placeholder1.Controls.Add(literal);

Now you'll get hihi

Not only that; it's quite complex as well.

You need to dynamically create the control in the Init phase and then hook up its Click event to a method. The control is then recreated after a postback and the Click will work.

This may be a good place to start to learn more about this: http://www.singingeels.com/Articles/...in_ASPNET.aspx

Also, Google knows more: http://www.google.com/#hl=en&q=dynam...ai=&fp=1&cad=b
