Accessing User Controls

[michael234]

Hi All,

Before i get into things I'm writing in C# using VS2003 with framework 1.1.

I am having a problem accessing a user control in the code behind.

I'm using the user control for some repetitive code and i need to access a public property.

.aspx

<%@ Register TagPrefix="uc" TagName="Activity" Src="includes\inc_Activity.ascx"   %>
 
<uc:ACTIVITY id="Activity1" runat="server" src="blank.html"></uc:ACTIVITY>
 

.aspx.cs

public class client : System.Web.UI.Page
{
protected ACTIVITY Activity1;
//...
 
private void Page_Load(object sender, System.EventArgs e)
{
Activity1.sPage = "Client";
//...
 
 

.ascx.cs

private string _sPage;
public string sPage
{
    get    {
        return _sPage;
        }
    set {
        sPage = value;
        }
}
 
 

Error when compiling;

The type or namespace name 'ACTIVITY' could not be found (are you missing a using directive or an assembly reference?)


Any help would be much appreciated!

I think this should have been under the .NET forum and not in C++ forum

I am moving this to the .NET forum.

Hi there!

When you register your user control:
[code=asp]

<%@ Register TagPrefix="uc" TagName="Activity" Src="includes\inc_Activity.ascx"   %>
 
<uc:ACTIVITY id="Activity1" runat="server" src="blank.html"></uc:ACTIVITY>
 

Make sure that your referencing the proper directory.
For starters you should be using forward-slash "/" instead of back-slash "\" in your Src string:

<%@ Register TagPrefix="uc" TagName="Activity" Src="includes/inc_Activity.ascx"   %>
 
<uc:ACTIVITY id="Activity1" runat="server" src="blank.html"></uc:ACTIVITY>
 

Make sure that you have a directory in your project "includes".
If need be refer to it using reference notation....eg:

<%@ Register TagPrefix="uc" TagName="Activity" Src="~/includes/inc_Activity.ascx"   %>
 
<uc:ACTIVITY id="Activity1" runat="server" src="blank.html"></uc:ACTIVITY>

Thanks for the response.

I have changed the / as you recommended and i do have the folder structure setup.

The user control does compile and run, the only problem i am having is accessing the public property from the code behind in the page that "includes" the user control.

If you have any ideas why this may be happening or a direction i could look to it would be much appreciated!

Cheers,
Michael

Hi Guys,

I have found a work around for my problem. The purpose of my behind code reference needs was to find out what page was using the user control through the public property. I found that i can set the value of the property through the aspx page.

<uc:inc_Activity id="inc_Activity1" runat="server" src="blank.html" sPage="Client"></uc:inc_Activity>

in doing this i now have no need to reference the user control through the code behind.

Cheers,
Michael
