Can't get TagPrefix to work for custom Web control

[Michael Skelton]

Hi

I've created a new custom Web control. I have tried to customize the assembly attribute TagPrefix . However, each time I drag my custom control onto a form, it's TagPrefix is still "cc1". What am I missing here

My control is nested within two namespaces: for example, OuterNamespace and InnerNamespace. Taking that into account, the AssemblyInfo.cs of my custom control's solution contains the following additional lines

..
using System.Web.UI
..
[assembly: TagPrefix("OuterNamespace.InnerNamespace", "mas")
..

I build my custom control, add it to the VS Toolbox, and test it by dropping it on a form. Alas, instead of being prefixed by "mas", the control is still prefixed by "cc1". Any advice on this one

Thanks in advance
-Michael

Hi,

Your approach is perfect. I have done the same thing with my custom
control and I get the custom prefix. My doubt is on some typo on your
namespace. Try changing the namespace of your custom control to something
different and copy and paste the same onto the attribute and see what
happens, to rule out this possibility.

Thanks for the advice, I'll try that.
