_EditCommand not firing...

jef · Mar 18, 2005

I realize this should be simple... but I'm at my wits end. I'm new to
ASP.NET (.NET in general) but have many years experience with VB6. I
have a very simple Datagrid with 2 columns bound to a datasource. I
have a ButtonColumn in the grid (my grid is called grdShow). My code
behind has a grdShow_EditCommand() function which handles
grdshow.EditCommand... but it doesn't fire when I click the Edit
button. I've searched for days on this and everything I find eludes to
adding an "OnEditCommand=xxxxxx" attribute to the grid in the .aspx
file. I can't find anything documented to show me how to do this... Am
I naive to think that I shouldn't have to "hard-wire" all of the
events... this is beginning to feel like a step back in technology...
not forward...

Without seeing more code, I can't quite be sure what your problems is, but
a comment about something you mentioned:

this is beginning to feel like a step back in technology...
not forward...

HTML/browser based applications *are* a step backwards from the deskstop
style applications you're used to in terms of presentation and responsiveness.
But it's the price to pay for a no-client install since "all they need is
a browser". If someone (your boss) asks you to reproduce 100% of the functionality
from your VB6 app in ASP.NET you need to have a nice long chat with them...
This isn't the same environment. Now... having said that, as long as expectations
are set properly, you can (and I'm sure you will) build great apps in ASP.NET.
Just be aware that it's a different paradigm with its own pros and cons.
