Hi everyone. I need to do the following but have been unable. I was wondering if anyone can point me in the right direction.
Something like this in the aspx :
<asp:linkbutton id="bla" runat="server">
<%= getLinkText("bla") %>
or
<asp:linkbutton id="bla" runat="server" text="<%= getLinkText(" bla")="" %="">" />
"getLinkText" is a method define in the codebehind class that returns a string with the text the link should display.
Neither of these work. Is there anyway to make this possible ?
TIA
Marco Cunha

In the page load event on your code behind couldn't you just say myLinkButton.Text = getLinkText("bla")?

I am not 100% sure what you are actually trying to do but here are a few solutions which may help you.
For some odd reason I also cannot define a variable in my Code Behind file and then use it in the aspx, still trying to figure that one out.
But what you can do is use a Label control and set the Label controls Text property to getLinkText("bla"). The Label control just outputs whatever you put in really, does not have any begin or end Tags.
However if you need the getLinkText("bla") result to be the HREF of an A Tag then use the Hyperlink Webform control. Then you can reference it from your Code Behind code easily.
If you fill us in on what you are actually trying to achieve then maybe we can help more

What were you trying to do with it? From what I can tell the code behind uses elements from the ASPX, if those aren't present then the new element needs to be added to the Page's Controls collection.
Is my thinking really far off from what you were trying?

I started typing a reply to you, explaining my problem and what I was trying to do. I even put some code into explain it well...
Then it twigged. Your words "needs to be added to the Page's Controls collection" made me think "Hang on, if I declare a string in the Page class, then maybe I can access it in the ASPX file..." and it worked!
Woohooo, so you solved my problem. Thanks James.
FYI for anyone interested here is the problem and solution:
Initially in my ASPX file I had:
...
<head>
<%string strPageTitle = "Page Editor";%>
<title>Numerica - <%Response.Write(strTest);%></title>
</head>
...
(I used the strPagetitle for other things if you were wondering why I went to all that trouble)
However I wanted to declare that strPageTitle variable in the ASPX.CS (code behind) file, not in the ASPX file. I could not figure it out until James here helped. And this is the solution.
ASPX.CS file:
public class pagemanager : System.Web.UI.Page
{
protected System.String strTest;
private void Page_Load(object sender, System.EventArgs e)
{
strPageTitle = "Page Manager";
}
...
And with that I could reference strPageTitle in my ASPX file just fine.
Woohoo! Ta James, you opened my eyes a bit more to how the whole ASP.NET model works.

I ended up using the Page_Load event to load the LinkButton text like had been suggested.
I'm creating a user web control and needed the ability to let the user configure the link text to whatever he wanted (making localization possible).
Thanks for your replies guys,

I have a form that sends data to a Access Databse. and everything works great. When I click on the submit button, it clears the form and allows me to add another record. I want to have a few fields retain the same data from the previous record. My main question is, should I be doing this with a cookie?
|
|

A cookie is one way, but anyone who has cookies disabled in the browser would be unable to use it, or be forced to put your website in a more trusted zone (where cookies are enabled). A simpler method would be to use hidden fields on the form. When the form is posted, the same fields could be resent to the client as part of the new blank record. If this is user-type information, for instance, the hidden fields could be initialized at the session level to reset them for each user.

You could do it with a cookie but that probably is not the best way.
Here is how I would do it (and I am assuming you are using ASP, not ASP.NET, if not then just message back and I will show you how in ASP.NET):
<%@ Language=VBScript %>
<%Option Explicit%>
<%
Dim strNameFirst, strNameLast, dtmDateOfBirth
strNameFirst = Request.Form("txtNameFirst")
strNameLast = Request.Form("txtNameLast")
dtmDateOfBirth = Request.Form("txtDateOfBirth")
'- Now do your database code to save the record, but only if there is something to save
If Request.QueryString("mode") = "save" Then
'- save to db
End If
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title></title>
<link rel="Stylesheet" href="main.css" type="text/css" media="screen" />
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
</head>
<body>
<form name="frmPerson" method="post" action="tet.asp?mode=save">
<table>
<tr>
<td align="right">First Name:</td>
<td><input type="text" name="txtNameFirst" value="<%=strNameFirst%>" /></td>
</tr>
<tr>
<td align="right">Last Name:</td>
<td><input type="text" name="txtNameLast" value="<%=strNameLast%>" /></td>
</tr>
<tr>
<td align="right">Date of Birth:</td>
<td><input type="text" name="txtDateOfBirth" value="" /></td>
</tr>
<tr>
<td align="right" colspan="2"><input type="submit" value="Save & Proceed" /></td>
</tr>
</table>
</form>
</body>
</html>
So basically when the page loads the first time it tries to retrieve the values of txtNameFirst and txtNameLast from the form POST data. However because this is the first time there is no data, but no worries because no error will be raised.
It then ensures that you don't save any new blanl records to the dB with the If.
Then the HTML and form is returned, if there is a value in the strNameFirst or strNameLast variables then they are shown in the text boxes, if not, then nothing is shown in the text boxes. Once again, no error if blank.
When you submit the form it does this all again but this time with values in the text boxes it can "retain state" and show what was typed in last time.
If you want default values then you can init the variables with a default value.
One nice thing about ASP.NET is that it does this kind of thing automatically! So swap to ASP.NET 
Good luck Kashmir9999

Does anyone know of any resources that compare the .NET framework with J2EE.
I'm interested in examples of which is more robust and scalable etc.
TIA.

Unable to get syntax highlightning and command-completion to work in VS.NET with a regular *.aspx page 
Anyone have any tips on how to accomplish this?! I tried to create a forms-page and separated the code to the file.aspx.cs-source, but it appears i manually have to compile the file and also get 2 files per page (*.aspx and *.aspx.cs).

vs.net only supports intellisense with the codebehind model.

That really sucks!
It makes regular aspx-editing a pain in the ass. Just hope there is a way around it and/or they fix it in the first service-pack.

Yes, you have to handle the OnPageIndexChanged Event and bind the data again with setting the CurrentPageIndex property to the selected page index.
See, OnPageIndexChanged Event help in MSDN documentation. They have a sample also.

Yes you have to add your own code (as the other guy said).
But on that note I was highly disapointed when I tried the DataGrid for the first time and figured out that all it did re: the Paging was put in the link really. What a cheek. It can't take MS more than a few minutes to add in the extra code.
Anyway. I was wondering if it was possible to inherit the DataGrid and make my own ASP.NET Webform Control which had the Paging code built in? I would think it is possible but before I start banging my head away at it I would like some confirmation.

Is is possible to change the cursor shape for netscape4.x ?
If yes, How ?
|
|
|
|
|
Sure, all you need to do is write a custom app that installs a hook on any running instance of NS and subclasses WM_MOUSEMOVE. You can then change the cursor for the app. Don't forget to force all your NS visitors to download and install the program.
Other than that... you're SOL.

While your at it, have your app uninstall NS and force the user to use IE. It will sure make my job (and many, many others) easier.

How can I change browser window title dynamically using javascript in Netscape.
window.document.title = "abc"
does not seem to work with Netscape.
Is there any other way I can change window title dynamically in netscape ?
|
|
|
|
|
Unfortuantely the document.title property is read only in netscape (maybe different in 6+) hence why document.title = 'blah' will not work (pretty not annoying  ).
Anyway I came up with this solution (although it's not ideal as it will nead a page reload).
Add this between the head tags:
<script language="Javascript">
var url = document.location.toString();
var posQry = url.indexOf('?') + 1;
var posTitle = url.indexOf('title=') + 6;
var posEnd;
var strTmp;
var arrSplits = new Array();
var idx = 0;
var strTitle = '';
if(url.indexOf('&') == -1)
{
posEnd = url.length;
strTitle = url.substr(posTitle, posEnd);
}
else
{
strTmp = url.substr(posQry, url.length);
arrSplits = strTmp.split('&');
for(idx = 0; idx < arrSplits.length; idx++)
{
if(arrSplits[idx].indexOf('title=') != -1)
{
strTitle = arrSplits[idx].split('=')[1].toString();
}
}
}
document.write('<title>'+ strTitle + '</title>');
</script>
When you want to change the title of the page you will need to reload it with a querystring key/value pair with a key of 'title'.
e.g.: <a href="myPage.html?title=A%20New%20Title">Change</a>
Your other alternative would be to do the same but server side.
e.g.(asp): <head><title><%=Request.QueryString("title")%></title></head>
hope this helps you.

I have a web form,when it loads,in Page_Load I open a connection to a database,and I use this connection in some functions,I don't know where should I clode this connection?In which functions? Should I open/close it in another place?

That really depends on the purpose of the connection on your web form. If this is the only place that you use your connection, you may consider leaving it where it is. Otherwise, if your application can use the same connection other places you may consider a function to be more adequate.
