accessing User Controls - URGENT please help!

[Dan Nash]

Hi all,

I've got a page with a user control on, added via VS. I'm trying to get to a
property of the user control (or more precisely, a public var).

Here's the code at the top of my aspx page...

<%@ Register TagPrefix="dI2" TagName="dartsUC_rolodexsearch"
Src="dartsUC_rolodexsearch.ascx" %>

then in the html...

<dI2:dartsUC_rolodexsearch id="dartsUC_rolodexsearch1"
runat="server"></dI2:dartsUC_rolodexsearch>

and the top of the ascx file looks like...

<%@ Control Language="c#" AutoEventWireup="false"
Codebehind="dartsUC_rolodexsearch.ascx.cs"
Inherits="dartsIntranet.WUC_rolodexsearch"
TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>

My question is how do I get to the user control. If I try

protected dartsUC_rolodexsearch dartsUC_rolodexsearch1;

in my page cs file, I get a cannot find type or namespace
"dartsUC_rolodexsearch".

Please, please help. I've been stuck on this for 2wks now - can't find
anything that makes sense!

Cheers
Dan

Hi,

It is mentioned as in ascx file, the Inherits property is,

Inherits="dartsIntranet.WUC_rolodexsearch"

It means that, ur namespace is "dartsIntranet" and your class name is
"WUC_rolodexsearch".

So, if u like to use ur usercontrol in one of the aspx pages, create an
instance of ur usercontrol class and not the one that is given in the Tag
Prefix.

so the actual code be,

protected WUC_rolodexsearch dartsUC_rolodexsearch1;

Kamal T.

Kamal,

Thanks, that'sworked. Sort of. I still cant get access to my variable though.

I added the line you suggested. I also added a label to my page.

Now, the final line in my control is rolodexSQL = "SELECT * FROM ContactsDB";

so, in my aspx page, I'm doing

lblSql.Text = dartsUC_rolodexsearch1.rolodexSQL;

The rolodexSQL part popped up in the drop down list, so that was nice.
However, when I run the program, I get nothing in my label control. Almost
like rolodexSQL is returning "" or null. If I add .ToString() to the line, i
get a "object reference not set to an instance of an object" error.

Any ideas much appreciated :o)

Cheers

Kamal,

Thanks, that looks better, however it's still not working. I wrote the
property as so...

private string rolodexSQL;
public string GetRolodexSQLValue
{
get
{
return rolodexSQL != null ? rolodexSQL : "NA";
}
}

and then in Page_Load of the control..

rolodexSQL = "test";

then, as the last line in my aspx page_load...

PageTitle.InnerHTML = dartsUC_rolodexsearch1.GetRolodexSQLValue;

where PageTitle is the id of the <title> element with a protected var
attached.

Compiles and runs fine, but I always get NA in the title bar. It's like my
statement

rolodexSQL = "test"; statement is being ignored completely.

:(

Thanks for your help

Hi peeps

Further to the earlier post, I've done some more investigating.

It seems that, although I cannot get to the variable from the user control,
I can infact get to it in the aspx page with the following statement...

<%= dartsUC_rolodexsearch1.GetRolodexSQLValue %>

Any ideas why this works and yet I can't get to the UC variable in
code-behind, which is where I actually need it.

Cheers
