Hi all,

I have a div tag in my user control, and I want to show/hide this div based on which page I am on. So here is what I have now.

in .ascx page,

....content

in ascx.cs page:
public string ReturnVisibility()
{
string class= "CssShowDiv";
if (Page.Request.Url.ToString().IndexOf("page1.aspx") > 0)
{
class= "CssHideDiv";
}
return class;
}

The result is that it works fine in a normal window. But if I open the page in a popup window using javascript, the div tag content always shows on the page, even though the class is CssHideDiv.

Can anybody give me a hint what's wrong with my code?

Thank you very much!

Half of your code doesn't show up. Use the "Ignore HTML" option when you are posting markup code.

I guess, maybe. the path of CSS file in popup window is wrong??

No, that's not the code that you are using. You can't name a variable "class", so that code doesn't even compile.

Show the code that you are actually using. I can't see what's wrong with the code that you are using by looking at some other code that you are not using.

If you have as condition that the value that IndexOf returns should be greater than zero, that means that if the string is found at the first position in the url, the condition will be false. Not that the url is likely to be only the page name, but you should be aware of it.

The server isn't even aware that the page will be shown in a popup, and none of the code that you have shown would act any different in a popup, so the problem is in some of the code that you haven't shown.

I have the following in .aspx page:

<img src="btn_print.gif" OnClick="javascript:OpenSummaryPage();"/>
<input id="hdShowComment" type=hidden value="0" />

The OpenSuin .js file
function OpenSummaryPage()
{
with(aspnetForm)
{
var url ="summary.aspx?comment=" + hdShowComment.value;
window.open(url);
}
}

The function in ascx.cs page is actually like this:
public string ReturnVisibility()
{
string divCssClass= "CssShowDiv";
if (Page.Request.Url.ToString().IndexOf("page1.aspx") > 0)
{
divCssClass= "CssHideDiv";
}
return divCssClass;
}

In .css file:
.CssShowDiv{DISPLAY: true}
.CssHideDiv{DISPLAY: none}

Thanks for help!

The javascript: protocol is only used if you put the Javascript in an url. If you use it anywhere else, it isn't recognised as a protocol but it becomes a label instead.

As you are using xhtml, argument names have to be lower case.

<img src="btn_print.gif" onclick="OpenSummaryPage();"/>

vicky457 wrote:

Use the getElementById to access elements in the page.

var url = "summary.aspx?comment=" + document.getElementById('hdShowComment').value;

vicky457 wrote:
.CssShowDiv{DISPLAY: true}

"true" is not a valid value for the display style. Use the value "block" to display a block element (e.g. a div) and the value "inline" to display an inline element (e.g. a span).

Have you verified that the css really is used on the page? You can for example add a background color or a border to some element on the page to see if it's used.

Css files are cached longer than pages, so an older version of the css file might be used. Press ctrl+F5 to reload the page and all files it uses.

I just found out the problem is caused by a stupid mistake. There is duplicated CssClass is defined, one is in Master page and is called CssHideDiv, the other is in .css file and is called CssHiddenDiv. The open widnow is not using master page, but is using CssHideDiv. This is a mistake introduced by multiple developers defining the same css class.

Thanks for everybody's help! I appreciate it!

Hello,
I want to create a SOAP message Handler for securing my web services. The .NET plateform offer this possibility with the SOAP extension.

But can this method be used with other plateform web services (java...) and how do it work?
In other words, can we create a SOAP message handler for all web services?

Thank you.

This is a fairly common example used for AJAX books, I know AJAX in Action walks through how to do it.

If you're using ASP.NET, the ASP.NET AJAX library probably has this control in it.

Tx for the solution. Although can it be done using Javascript instead of AJAX.

Are you using Visual Studio 2005? By the way, your questions is not related to "Web development"...
