    DataGrid no showing up

    Ok, I solved the wwwrooot$ issue-thanks!
    I am building a sample app as described in the book "Visual Sudio.Net Walkthroughs" that came with the software.
    I am building the ASP app that starts on page 96. I built the
    data grid over titles dataset on Pub db. When I actually
    run the thing, I get nothing but a blank screen. I added static
    text to insure the form is loading, it is. I checked and rechecked
    the instructions to be sure I did it right. Still it did not return
    ant datagrid. The data is there. Unfortuantly the software
    says that the components to debug are not on the server (???)
    so I cant debug. Any suggestions?

    Without having the book you mention, it's a little difficult to help. I use ASP.NET without VS.Net.

    Real programmers use Notepad.


    OK.....Uhmmmmmmm......

    1) Using IIS local with latest NetFramework installed ?? Other non-data APS.Net pages run ok ?? Using web-hosting co that actually has ASP.Net working ?? (www.brinkster.com officially has it for General members, but it doesn't work)

    2) can you response.write all the data out ??

    3) <% Page debug="true" %> is at the top of page ???

    4) Your actually binding the data ??

    obj.DataSource = DataReader/DataList/whatever
    obj.DataBind()

    5) Can you fill grid using just an array ???

    Dim arr as ArrayList= new ArrayList()
    arr.Add ("test")
    arr.Add ("test2")
    obj.DataSource = arr
    obj.DataBind()

    6) Tracing set on ???

    Using what came out of the box (1.0)

    Yes


    >>> Using web-hosting co that actually has ASP.Net working ??
    what do you mean "co"? We are using a NT 4.0 server as
    an "intranet" sandbox. Nothing in production just yet


    www.brinkster.com officially has it for General members, but it doesn't work)

    >>>>2) can you response.write all the data out ??

    Do not know how to do that. This is my first Foray into anything ASP or .NET for that matter


    >>>>>3) Your actually binding the data ??

    on the page load I am using "datagrid1.databind()" just like
    the book tells me to.

    >>>5) Can you fill grid using just an array ???

    Dim arr as ArrayList= new ArrayList()
    arr.Add ("test")
    arr.Add ("test2")
    obj.DataSource = arr
    obj.DataBind()

    Gonna tryit

    >>>6) Tracing set on ???

    Do not know how to do that (excuse my wet ears)

    Thanks

    Sorry to throw so much at you, but when you post, it's a good idea to include as much info as possible.

    OK......non-data ASP.Net pages run ok so we can assume IIS(your web server) and the NET Framework(sw to run NET code in IIS) are installed ok.

    Just noticed your next post about the arrays....This is just a small sample from a book ??? Post the code. Just replace any details about database names and passwords with "X"'s.

    no data grid. So we got some system bug?

    The same error as before ??

    "components to debug are not on the server " ??

    This sample is as simple as it gets. After this, I would say your setup on the server is hosed in some way.(again, copy to a single file with a ASPX extension)

    If this doesn't work, take any error message and search at

    MSDN at Micorsoft.com


    <html>
    <body>
    <h3><font face="Verdana">Declaring Server Controls</font></h3>

    This sample demonstrates how to declare the &lt;asp:label&gt; server control and
    manipulate its properties within a page.

    <p>

    <hr>

    <asp:label id="Message1" font-size="16" font-bold="true" forecolor="red" runat=server>This is Message One</asp:label>

    <br>

    <asp:label id="Message2" font-size="20" font-italic="true" forecolor="blue" runat=server>This is Message Two</asp:label>

    <br>

    <asp:label id="Message3" font-size="24" font-underline="true" forecolor="green" runat=server>This is Message Three</asp:label>

    </body>
    </html>

    Datagrid

    Yes, I did run your sample and got the same type of results as
    did the app. There is no error message I can see. Everything
    acts "normal" I also tried out the Web service exmple from
    this site and it doesn't work right either. When I try to "view
    with browser" as Karl Moore instructs; I get the OS asking if
    I want to open or save to disk the service. When I say open,
    I get nothing but a source code string. I also can't find the service when I tried to add the Web refernce to the VB app. I suspect my install was bothced. I had to put the stuff on the D: drives because of space limitations on C:. The server was built using FAT so my disk space was only 2GIG. Going to have it rebuilt as NTFS

    NTFS isn't going to help you. I have Windows 2000 and IIS running on a FAT32 system with no problems.

    Instead of trying to "view with browser", just type the local url in. I get the same "open or download" when I try to open an ASPX page because I have an editor set as the default for those files.

    Make sure that ASPX page is in the wwwroot folder and try naming it Default.aspx. The just type in your local url.

    http://yourservername/

    Deafult.aspx should load auto. If not, then IIS isn't setup right.

    Went into the IIS service manager and made sure under "enable
    default document" that the original "default.html" page was keyed
    in. When I key in "http:/tetbox1/" It does not go there, I just get a directory listing. When I select the original default.html from there it displays ok. When I substitute the .aspx sample, I still get the text, no data grid. When I substitute the web service, It want to open/save. Same old same old. So I guess my IIS is not quite right?
    Thanks

    i just did a datagrid yesterday, and i'm just trying to remember off the top of my head what i did as i also got nothing on my screen the first few times. that normally means that there's no data... (so i figured out!)

    did you try to test your sqldataadapter?

    i think if you go to it's page properties or advanced properties, there is somewhere that it shows you the sql statement and all the fields that it will return.

    click on the fill button. did any data appear?

    i will go and check out this example when i have a chance...

    DataGrid

    Yes! As a matter of fact I did find that, and it filled the data A-ok.

    However, I think I go to the root. A co-worker was doing some frontpage ASP on the same server and he got an error message that the server is not set up to run ASP. So I think that is the problem. I would of been nice if I got a message like that. I guess we are runniong IIS 3.0, we will upgrade to 4.0 and see what happens
    Thanks

    should'nt you upgrade to iis 5?

    why don't you try it out on your local machine first?

    AC,

    I think 4.0 is all the guy had at the time.
    There is yet another update. ASP runs fine, but the ASPX is
    what is not running correctly. I found this out when I went
    to a MS help guide installed on the machine. It was executing some ASP pages just fine.

    When you say "run on your local machine", I am not quite sure what you mean. I am developing on a server that has IIS and
    VS.NET loaded. I attempt to execute the ASPX I created on that same machine and am getting these problems. If I try to
    execute the ASPX from my other NT workstation as is it was
    a client with a browser, I am getting the same results.
    However, my workstation has just been upgraded to 2000 professional, the server still remains as NT 4.0


    Thanks again

    Tom

    when i say locally, i mean install vs .net on your own machine. it should install a web server with it i think? (iis 5)

    then first develop and test on your own machine and then go and look why it's not running on the server.

    when you say that vs .net is installed on the server, does that mean that all the development tools are also installed on it? or only the framework?

    what are the error messages that you get?

    DATAGRID

    ac,

    I have the framework and .net development tools installed on the NT 4.0 server. I am executing the developed ASPX pages on that
    same machine. **Everything on one machine**. When I execute the aspx page, I get no error message that I can see. It just shows only the static text, but no DB operations such as the datagrid. I was just told by the NT guy that IIS 5.0 does not work with NT 4.0

    Thanks
    Tom

    PS does AC stand for Allis Chalmers by chance? (I am a AC nut)
