I have a MainMaster Page. I created SubMaster page using the above MainMaster page.
I creted a Content Page called MyContentPage using this SubMaster Page. I have a Label
inside the SubMasterPage. I want to Grab the Value of the Label in my MyContentPage.
This is what i did for this
I have a label like this in SubMaster Page.
asp:Label ID="Label1" runat="server"
In SubMaster Page cs file i just assign a string called Test to the Label1
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Label1.Text = "Test";
}
}
In MyContentPage i did this below
protected void Page_LoadComplete(object sender, EventArgs e)
{
string test = (Master.FindControl("Label1") as Label).Text;
}
The above one is throwing up an null point exception error
Object reference not set to an instance of an object
Now i Created a content page using the MainMaster Page and repeated the above process
and it seems to work fine(i.e able to pass the label value from MainMaster Page to Content Page)
Can you guys tell me what iam doing wrong with the first case as soon as possible

Are you using the nested Master Pages? In this case, the simple way to figure out the way to get reference to the Label is to look at the control tree of the web page. You can simply set the Trace="true" in the Page directive or run your application in debug mode. When you see the control hierarchy, you will see that you need to first get reference to the PlaceHolderControl placed in the Main MasterPage, then keep using the FindControl method to access the Label control in the Sub MasterPage. Also you should remember that the Page_Load of the Master Page runs after the Page_Load of the content page, so the value you get in the content page is not what you assign in the Master Page.

This is such an easy question that I'm embarrassed to ask.
I have a css stylesheet and an asp.net page written in vb.net - how do I apply the stylesheet to the vb.net page ?
Is there a way that I can assign it at a project level so I dont have to set it for each page ?
Thanks, Digsy

You will have to put this in the <head> of each page:
<link href="Path To Your Style Sheet" rel="stylesheet" type="text/css" />
You could always use a MasterPage, but the style sheet in that, then have all your pages use the MasterPage. It is what they're for.
|
|
|
|
|
Also, you can just drag your stylesheet from solution explorer onto the designer and it puts the link in there automagically.

Well, master pages can be used that way, but they are more about separating page content from site content.
Themes are made for applying style to pages. Create a theme, put the css file in the theme folder, and a link tag will automatically be added to the head of each page that uses the theme.

I would argue that a site's style and content go together and both fall under the purview of the MasterPage.

Hello,
I cannot see ASP.NET TAB in my IIS. I am running .NET 2.0 on Windows Server 2000. It is having IIS 5.0
Any clues?

My experience is that the installation of the 2.0 framework, provided that IIS is already installed, will hook the IIS manager with the ASP.NET configuration tab. Are you certain 2.0 is installed on that server? (is it possible it is 1.1 instead?)
|
|
|
|
|
I have .NET 2.0 installed. I have also added .NET Management Extensions in MMC, but still I do not see the ASP.NET TAB.
Note: The server is Windows 2000 and IIS is 5.0

comm.CommandText = "select distinct BrandID,Brand as PictureFileName" +
" and BrandID = @BrandID";
comm.Parameters.Add("@BrandID", BrandID);
SqlDataReader dr10 = comm.ExecuteReader();
CatName.Text = dr10;
dr10.Close();
the above code is SUPPOSS to query BrandID from the database table Brand and show it out in the label.
pls some one debug this i think it went wrong somewhere >.<

Your query doesn't appear to be valid SQL. I'd recommend checking this[^] quick reference on basic SQL syntax.
Hope that helps.

What is it that you are trying to do, really?
I have seldom seen a piece of code with so many errors... 
Let's have a look at your code:
comm.CommandText = "select distinct BrandID,Brand as PictureFileName" +
" and BrandID = @BrandID";
Why are you using distinct? Can there more than one record with the same BrandId?
You have forgotten the keyword "from" before the table name.
You are creating the alias "PictureFileName" for the table, but you are not using this alias anywhere.
You have forgotten the "where" keyword.
You have the operator "and", as if you were trying to combine conditions, but you only have one condition.
If you fix the query so that it works, it's still pointless. There are only two different results that you can get from it; either the exact same value that you put in the parameter if there is a matching record in the database, or an empty result if there is no matching record.
comm.Parameters.Add("@BrandID", BrandID);
Looking good. You might consider to specify the data type of the parameter once you get it up and running, though, to save a round trip to the database.
SqlDataReader dr10 = comm.ExecuteReader();
Nothing wrong here.
CatName.Text = dr10;
You can't put the entire DataReader object in the label. You have to read a value from the DataReader, perhaps using the GetInt32 method.
Before you try to read anything from the DataReader, though, you have to call the Read method.

Another correct line.

comm.Parameters.Add("@BrandID", BrandID);
SqlDataReader dr10 = comm.ExecuteReader();
CatName.Text = dr10;
dr10.Close();
is this how it should be done?

That's a lot closer.
You are still not calling the Read method before you try to read from the DataReader, and you are still trying to put the entire DataReader in the label.

i think i understnd where you are going but could you show an example or something since i have never used the read method or the GetInt32 method before
and the webpage about the sql syntex doesnt seems to have it as well >.<

please help me evaluate >.<
the sql database consist of 3 attributes BrandID,Brand,Brandlogo
comm.CommandText = "select Brand from Brand where BrandID = @BrandID"; //select which data i want from the database
comm.Parameters.Add("@BrandID", BrandID); //add parameters to query
SqlDataReader dr10 = comm.ExecuteReader();
dr10.Read(); // Call Read before accessing data.
int id = dr10.GetInt32(0); //<== this part i dont quite get it becoz my result was supposs to be an string
CatName.Text = id.ToString();
dr10.Close();
if the above code have anything wrong please tell me where cause i tryed to run it and it still cant work
(p.s thansk to all those who have been helping me)

Then you use the GetString method instread.
Do you remember that the very first thing I asked you was what you were trying to do? You never answered that, so I still have no idea if the code is even remotely close to what it is that you are actually trying to do.

Hi,
I have a web application and users can register themselves on it.
I would like to have special URLs for each client that is a registered user, much like a friendly URL.
a good example would be the way myspace.com works...
a registered user can have www.myspace.com/joebloggs as their myspace url.
i have tried to get this to work but can only manage to get www.mywebsite.com/joebloggs.aspx to work.
I do this by having a custom 404 page then perform a database lookup based on the name and redirect to their page.
If i drop the aspx off the end IIS kicks in and shows its own 404 page.
Is their any way i can have it without the aspx on the end? so it would be www.mywebsite.com/joebloggs
I am using asp.net 1.1 with visual studio.net 2003.
Thank you in advance for any help.
Regards,
Guy

It sounds like you'll want to look into url rewriting. To get you started, here are a couple of articles that Google spit out for me:- Richard Birkby's article[^] here at CodeProject
- Robert Chartier's article[^] at 15 Seconds
- Jesse Ezell's blog post[^] on working around some common problems
Just for completeness, here[^] is the search that gave me those results. I hope that helps to get you started.

Have the real address be www.mywebsite.com/joebloggs/default.aspx and you can just do www.mywebsite.com/joebloggs/ and if you have the default document set to default, it works. You can even do query strings: www.mywebsite.com/joebloggs/?sec=2&page=3

surely that means i would need to have a pre-created directory with the name 'joebloggs' though???
i dont really want directories for each user i just want it to be dynamic.
Because there is only ever really one page called viewclient.aspx this accepts an ID as a parameter and shows the clients content based on the ID.
So to view joe bloggs client page i want to type www.mywebsite.com/joebloggs
Is this actually possible in asp.net?
im wondering if i could do it by changing the IIS error page for 404.
then checking the url asked for (the query) and then looking this up in the database.
anyone know if this type of technique would work and how to achieve it?

It is possible through the use of url rewriting, and in a much more efficient way then using a 404 error as flow control. I linked several articles to get you started in my initial reply.
