Hi to all !
I'd like to understand, where in the resulting ..._aspx class goes inline code,
found on the page inside code brackets.
I want to create the dynamic page, where the existence of controls is managed by parameters,
say, from querystring.
Is the following the best way to do it:
<asp:inbox runat="server" ID="box1" .../>
<% if (Request.QueryString.Get("par")=="2"){ %>
<asp:inbox runat="server" ID="box2" .../>
<% } %>
Or I have to get rid of designer and create the page programmaticaly in whole?
Thanks in advance.
Regards,
Gennady

You could do it that way, but I would suggest looking at the Placeholder control and something to use to hide or show your controls. On you page load even you can check the query string and show or hide the correct placeholders that have the controls in them.
Hope that helps.

Hi !
Thank you for your reply. I'll look at this control (I'm new enough in ASP.NET).
But my question was not exactly "how to do", but rather "how it works".
The thing is that I have to create the new .NET version of the existing site that is on high demand (about a million visitors per month). So performance is THE issue. I'd like not to squander resources on creating hidden controls and emitting the javascript code that will never work.
That's why I'm trying to understand what is going on under the hood.
Thanks once more.
Regards,
Gennady

With the placeholder control, when it is set to false, that html is not rendered in the page. I don't think you would see any performance issue. The code that you had for your example could have some performace issues since it is parsed.

Hi !
So, if I've understand right, the inline code goes to the Render method
of the resulting class?
As for Placeholder control, I have to learn it in comparison to Panel
or simply adding controls to the page collection in the Load event handler.
From the glance I cannot see great difference between these three options for my case.
May be in the event propagation model?
Thanks.

I don't think that is true. The panel and the placeholder control are similar. The difference is that the panel control can still take up some space in the html. The placeholder control will not.
The example code you used has the <% these tags are parsed later and take more time. Since speed is a concern I think you would be much better off using the placeholder control.

Thanks, Ben !
This is exactly what I'd like to understand - when and where.
But think, even the placeholder will not be a good alternative.
More I think about it - more I incline to the idea, that the best decision in my case would be
to write the kind of page generator, that will create "static" aspx pages (about 100)
on the base of page template and type definitions from the DB.
This has to provide the performance benefit, yet supporting the desired level of flexibility and
managability. I hope ...
Thanks.

For your simple example panels would be good. If you're doing anything really complex though you could take a look at an article I wrote about handling views here: http://www.codeproject.com/useritems/ViewManagerTutorial.asp
Just one more option. I'm honestly not sure how much of a performance impact this would have versus panels. Because of the simplicity of the class though I would have to lean towards that it may be a leaner solution.
If anyone has any discrete data to the contrary please correct me!

Hi !
Thank your for reply.
Concerning viewmanager, and also multiview and view controls - suppose I can use them,
say, to implement the tabs. But not in the case in question.
I think, it's not a good idea - generate 100 views per user request to always show him only one.
Or I didn't understand something?
To understand what type of site I mean - two links to the same site:
emap/English[^]
gj[^]
Thanks.

Gennady

Ahh I see what you're going for. Honestly in that situation I would use the view manager. The reason for that is that the purpose of the class is always to show just one view. The ViewManager only stores references to the controls which I believe should be pretty inexpensive and the time it would take to initialize it should be trivial.
Also when you have such a complicated view it seems like it would be nice to be able to initialize it with a single call.

Whenever I am composing a new email whenreading it in Outlook 2007 the words don't wrap at the end of a line on the right hand side of the screen. I used to use float=right and used to work in outlook 2003.
There is probably a really easy fix but I 'm drawing a blank on this one. Can anyone tell me how to make the make this happen?
Thanks!

Does your ISP allow sending mail from any server? Some ISPs only allow sending mail through their SMTP server, to prevent spamming.

Hi,
IMO the easy way is that you view the html source code of the page..then to detect where is the problem...

I am inserting data from one form into two linked tables "Student" and "Grade" linked together by the Grade_ID column which is a primary key in the Grade table and a forgien key in the Student table. After i insert the data i go to the database to see that the primary key
in the Grade table is inserted and its ok but the forgien key in the student table is still null. How can i link them together so that the forgien key in the Student table can take the same value as that in the grade table.

How to do updation of two tables in gridview?(asp.net2/c#)
|
|
|
|
|
Hi there,
Tell you what. That's a very good question. I have a clue about how you can do it. Maybe you can try it out. Here is how you do it.
Edit the Gridview template so that you get all the columns you want to update. To actually update it you can have an "instead of" trigger or a stored procedure which updates the values in the two tables.
Hope that helps.......
You don't have to be AFRAID!
