View 1 Replies(i) Default.aspx and Default.aspx.cs(ii) MyControl.ascx and yControl.ascx.csTo access MyControl.ascx from Default.aspx, we use following in Default.aspx:
Register
TagName="abc"
TagPrefix="Controls"
Src="Numabc.ascx"%>
But now I am wishing to access in MyControl.ascx.cs from Default.aspx.cs page. By default, I am totally unable to access any control or function exist in MyControl.ascx.cs file or say codebehind.
I was trying to access < script type='text/javascript' ....>< / script > existing within Head tag.
What I was doing to achieve that,
foreach (Control ctrl in Header.Controls)
{
Response.Write(ctrl.GetType() + "<br/>");
}
It gives me the reference of "title", "meta" and "literal" control. How can I get the control and get the "src" attribute of that tag.
im a little bit angry, because i realy don't know how i can access a virtual directory a created in the IIS.

Now how do i access this folder from code behind? I really tried everything but i can't load a image from this virtual directory :

I have a span control which I am filling using Jquery. At the page load I want this span say id1 to be invisible and depending on some conditions I am making it visible via jquery itself.
When I make id1 runat = server and try to access id1 from codebehing, then I get an error in Jquery.
Hence I need a way to make id1 invisble at the load time itself.
I have already set id1 = invisble in HTML, But still I see this control on the page till the time jquery fills the entire data.

While running ItemDetabound upon load of a listivew, I am trying to access the text in a label of the LayoutTemplate of a different Listview. It works fine if I try access the same labels under the same names if they are in the same listview, but not if they are in a different one. It was working for a while, can't figure out what I changed, but now says that object doesn't exist.

I have a problem with ASP.NET web configuration file. I want to deny some users or roles to accessing a specific PDF file. I am using ASP.NET membership and role management system. So I added this lines of codes to a Web.config file:
<location path="myfile.pdf">
<system.web>
<authorization>
<allow roles="admin"/>
<deny users="*"/>
</authorization>
</system.web>
</location>
and put it to the directory witch the file is included in it. Now when I run the project in local system I can not access the PDF file wile I login with "admin" role. But when I publish the project on the web server I can not brows the folder but I can view the PDF file when I browse complete path to the PDF file. So:
I can not access : [URL]
but I can view : [URL]
