Composite Controls and INamingContainer

bmains · April 15th, 2004, 07:42 AM

Hello,

I was working with a composite control, that for the life of me wasn't working at all. I added "Implements INamingContainer" and it works fine. Any ideas why that is? That really peaked my curiosity.

Thanks,

Brian Mains

Hi Brian,

Where you working with nested controls?
The INamingContainer takes care of generating unique names within the entire page scope. So, if you have a TextBox inside a Repeater, this class makes sure that each TextBox gets a unique name in each Repeater item by prefixing the TextBox with the Repeater name / ID.

Simply implementing INamingContainer enables this behavior for your own controls.

HtH,

Hey,

Thanks for the response. I had a control that had a label, two textboxes, two labels, and a link button. However, after reading your response, it dawned on me that I used several LiteralControls to output HTML for a table element that would format these controls, and I bet that is what is causing the problems.

Thanks,

Brian

You can take a look at the source of the page in the browser. If you see ID values with a colon, e.g.: myDataGrid:_ctl8:btnDelete you can be sure you had the INamingContainer at work.

Cheers,
