Prevent Multiple Templates

Question

User-626088549 posted

I have a custom server control that will looks something like this:

<abc:MyControl ID="MyControl1" runat="server">
    <ContentTemplate>
        Blah blah blah
    </ContentTemplate>
</abc:MyControl>

How can I detect if more than one <ContentTemplate /> template is present and throw an error?

by default it supports only one contentTemplate

While this is true, it simply overwrites the previous template. I want something that is a bit more obvious to let the developer know that they can't have more than one template.

Intellisense will tell the user that when he/she inputs the 2nd tag of that, no intellisense will be pop-up……

It doesn't. It let me put a second tag and the second tag's output overwrote what was in the first tag. Maybe I'm missing an attribute?

Hi,

As far as I see, I think if the intellisense cannot show that you've got a duplicated tag, I'm afraid you cannot recognize it……
