Overridden Control and IntelliSense

[Andrew Robinson]

I have an overridden control:

public class DJGridView : GridView { }

All works great except that I loose IntelliSense for all of the child
elements while editing the HTML file from within VS2005. Any suggestions on
what I could include within my control to enable this functionality?

Thanks,

Hi Andrew,

As for the Intellisense, it is controlled by the certain XML schema setting
of Visual Studio IDE. ASP.NET built-in server controls have internal XML
schema associated with them. For custom web server control, you may add
your custom schema:

Also, for ASP.NET 2.0, the schema generation of web control seems vary from
ASP.NET 1.x, you can have a look at the following blog entry:

Steve,

Thanks for the info but I am still pretty stuck. My issue is pretty specific
in that it involves inheriting from an existing control. Nikhil Kothari
stuff is very informative and I am sure he could solve my issue but I don't
see him specifically addressing it.

In my case, I am inheriting form a GridView and all of the top level sub
elements are available such as Columns, but the asp:templateField within the
columns fails to format or expand with intelli sense. The same goes for all
the 2nd level sub tags.

I kind of wounder if this is possibly a VS bug?

Thanks for your reply Andy,

For the case that you derive your custom control from an existing well
encapsulated one(like GridView), I've tested and the design-time
intellisense does work abit strange(only top level property will show
intellisense). I'll do some further research to see whether there is any
particular things we've missed.

Steve,

Any updates on this? Smells like a Visual Studio bug to me.

Thanks,

Hi Andrew,

I've replied your mail and currently based on some further discussion with
some engineer, this does likely be an issue of the Visual Studio
design-time intellisense engine as it doesn't correctly reflect the sub
inner properties of overrided custom GridView control. According to the
complexity of further troubleshooting on this issue, if this is an urgent
and high priority problem, I suggest you contact CSS for continue
assistance:

Meanwhile, if there is still anything we can help, please feel free to post
here.
