Hi,
I had a similar requirement. Essentially I was trying to create a web
app, that had a number of default forms where users would enter data,
but I wanted the ability to add new forms on the fly (typically from a
third-party source).
The simplest approach I found was to define my forms with XML. When
the app loads, it gets the XML from the server side and builds the
list of forms.
When a user actually loads a form, a parser goes through the XML and
constructs the appropriate widgets.
e.g.
<form>
<grid col=2 row=1>
<Label Name="test name" rowPos=0 colPos=0>Default Value</Label>
<TextBox Name="mybox" rowPos=0 colPos=1>Default Value</TextBox>
</grid>
</form>
The is obviously a simple version, but the above would construct a new
form and add a 1x2 grid to it hopefully looking something like:
______________________
| |
| test name __________ |
| |__________| |
|_____________________|
To add a new file on the fly a third-party just needs to submit the
forms xml to the server side DB. When a client refreshes their
browser the latest list of forms will be brought over.
