I'm not sure that's true. I think with a MultiView control, only the active View is sent to the user. I just did the following code as a test and can verify only the active View was sent.
<%@ Page Language="C#" %>
<script runat="server">
void Page_Load(object o, EventArgs e)
{
int index=0;
if (Request.QueryString["view"] != null)
index = int.Parse(Request.QueryString["view"]);
mv1.ActiveViewIndex = index;
}
</script>
<html>
<head>
<title></title>
</head>
<body>
<form runat="server">
<asp:MultiView id="mv1" runat="server">
<asp:View id="view0" runat="server">
This is view0.
<asp:TextBox id="txt0" runat="server" Text="View0" />
</asp:View>
<asp:View id="view1" runat="server">
This is view1.
<asp:TextBox id="txt1" runat="server" Text="View1" />
</asp:View>
<asp:View id="view2" runat="server">
This is view2.
<asp:TextBox id="txt2" runat="server" Text="View2" />
</asp:View>
</asp:MultiView>
</form>
</body>
</html>

So when you specify view 0 for example and view the page source in the web browser you don't see the txt1 or txt2 textboxes? I thought they were sent, just hidden at the client end because in many examples they describe showing different views *at the browser* by responding to click events etc. Or did I misunderstand that and they mean *at the server* after a postback?

Hi John. Nope- the hidden views are not sent to the browser at all.
Jon's point too about using a panel with visible=false works the same way. If it isn't visible, it isn't sent to the browser.
The one thing that may be sent would be viewstate for the controls - I'm not sure if viewstate for a hidden View in a MultiView control is sent to the browser or not. But if you try the example I posted for you, you'll see the hidden view controls are not sent to the browser at all.

Thank you Mike I appreciate it, I was making a bad assumption based on a 3rd party component's behaviour and a misunderstanding of some of the docs I was reading on multiview. I should have just tried it right off the start.
Cheers!

Perhaps I'm missing the underlying problem, but can't you just use an asp:Panel to wrap your sections and set Visible=false for the sections you don't want to display?
|
|
|
|
|
I'm trying to cut down on the size of the page sent to the user. Setting Visible=false still sends that panel section to the browser from the web server.

How are you setting it up?
This:

Thanks Jon, I was going by what I saw with a 3rd party component. I appreciate you taking the time to check it out, I should have just tested it with the stock component to begin with.
Cheers!

Don't know what browsers you have to support but couldn't you use iframe and point it to aspx or ascx as necessary?
only two letters away from being an asset

No it's not practical to do that, it's a very complex form with a very complex business object as the source of what's being edited on the form, to break it out into different pages would be a nightmare. There are about 20 controls in each of the three sections for a total of 60-ish and only 20 need to be displayed at a time. (I'm porting from a winform app)

Does anyone know how to get the date to 2 characters ie 2006 would be 06. this has been baffling me for a while now. Any help is much appreciated
|

Use the ToString() method of the DateTime object with a pattern argument that includes "yy" for a two-character year... something like this:
DateTime theDate = System.DateTime.Now;
String dateAsString = theDate.ToString("dd-MMM-yy");

Hi,
(Im new to using 2.0)
Im using Master pages to create the templates for each section of a website i'm developing. Using contentplaceholders i am able to create each unique page and simply pull in the lay-out from the master page as you would expect.
However it is important for each page i create to have its own metatags / title. How do i go about doing this, when this information is to be located in the head-tags and thus in the master page?
Shoul i create placeholders for the data? This doesnt seem to favourable as vis studio considers this to be erroneous.
Thanks
Phill

You can try
using System.Web.UI.HtmlControls;
HtmlMeta meta = new HtmlMeta();
meta.Name = "keywords";
meta.Content = "testing the keywords";
((NameOfMasterPage)Master).Page.Header.Controls.Add(meta);
But I'm not sure if this is the best approach.
Good luck!

Hi,
In Amazon website,When we click on TV,It displays the TVs available one after another i.e side by side.I think for each tv they are using formview or detailsview.I think so.
Whether we have to place one form view for each tv.
How they achieve it.
Thanks in advance.

I have an ASP.NET 2.0 page that generates a ZIP file on-the-fly and sends it to the browser, modifying the content-type to "application/zip" using the method Response.AddHeader().
The content is sent correctly, but the browsers ask to save a .aspx file, that actually contains ZIP data. I mean that if you change the extension to .zip, the file works.
This is obviously not the best way.
So, I'd like to know whether there is or not a way to change the "name" of the file in the Response, without using Response.Redirect(), so the browser actually "sees" a .zip file.
Thanks for any advice.
EDIT: solved, just add the header Response.AddHeader("content-disposition", "attachment;filename=File.zip").

Hi everybody.
I’ve develop a web application by asp.net 2 and I want to release it, via installation package. I can make a setup file for that. But I don’t know how to install internet information service (IIS) in the user’s computer via my setup file and my application needs IIS 4.0 or later to run. I search for that in my operating system cd. But I don’t find any installation file for that.
If anyone knows IIS setup file please send me its url.
Thanks

IIS is distributed by Microsoft and they control the rights. The user's PC must have the appropriate licence and they will then be able to install IIS themselves through the Add/install components section in add/remove programs.
You can't distribute IIS with your app.
|
|
|
|
|
so how other webapplication works in end user's pc. isn't there any better solution?
Thanks

They get installed on a pc with a webserver installed. If your customer wishes to buy and run a web application, then they must be equipped with the appropriate software to serve it...
