Hi
I've got an update business object method which takes about 80 parameters.
I'm getting the 'could not find a non-generic method' error. I know that the
ObjectDataSourc e UpdateParameter s matches the business object method
signiture. I ran the code below to discover that the InputParameters is in
fact a list of bound values in my FormView control, i.e. not the
UpdateParameter s list.
protected void ObjectDataSourc e_Updating(obje ct sender,
ObjectDataSourc eMethodEventArg s e)
{
foreach (DictionaryEntr y var in e.InputParamete rs)
{
Response.Write( var.Key.ToStrin g() + "\n");
}
}
What is the purpose of the UpdateParameter s if they don't get used? What am
I doing wrong or what do I need to understand about the ObjectDataSourc e
when using in this context?
Many thanks

Hi Andrew,
The new question you mentioned is a good idea. I haven't ever tried it(use
usercontrol as a shared template). However, I do know that you can define a
separate template file (which contains the ascx like markup in it) and
other DataBound control (which use template column) can dynanically
construct the template column by loading the template content from that
separate template file. Here are some articles introducing ASP.NET template
and how to can deal with it(dynamically load it):
#Loading ASP.NET Templates Dynamically http://www.dotnetheaven.com/UploadFi...5112005005542A
M/DynamicTemplate .aspx?ArticleID =6d76b182-d79f-49a3-99d1-f063bae3a930
#Differences in ASP.NET¡¯s LoadControl vs. LoadTemplate http://aspalliance.com/399

Hi Steven
Thanks for the articles about template controls. I've managed to get a
FormView to load templates dynamically. However it appears loading controls
this way is not compatable with 2 way databinding. Do you know if this is
possible without a lot of work?
Many thanks

Hi
Just wondered if this thread was still open and if there is any answer to
the question about using a separate template file in a FormView control with
2 way binding. Please see previous posts.
Thanks
Andrew
Hi Andrew,
Glad to hear from you. For the previous thread, due to some tool problem, I
haven't seen your last reply and I've manually query the web interface and
see it. So the new problem you meet is that you cannot get two-way
databinding work with dynamically loaded FormView template right?
I have also performed some test on my side and did found the problem
behavior you mentioend. It seems the "Bind" based two-way databinding will
not work(the update parameters are not automatically populated) when the
template is dynamically loaded from an separate file. Currently I'll do
some further research on this to see whether this is expected behavior or
not.
I'll update you as soon as I get any new information.
Sincerely,
Steven Cheng

Hi Andrew,
Here is something I've found. This issue does have been recorded since some
other members ever reported it previously. Here is a public web link to the
issue: https://connect.microsoft.com/Visual...ck.aspx?Feedba
ckID=104085
also, due to some design limitation, it is still unfixed in the latest .net
framework. However, the issue link does provide a workaround, you can visit
the following link to get the idea:

Hope this helps some.

The challenge is ObjectDataSource is not able to work with an update method
