Hi,
I am using TypedDataset in my appliaction, It has 3 tables and those tables have some relations among them. In the second datatable there are some computed columns(even it has some aggregate functions). When I am trying to set the one of the computed column as a parameter to my update storedprocedure it is raising an exception when i am calling dataadapter.update() method on the ssecond table.
It is giving {"The column mapping from SourceColumn "XXX" failed because the DataColumn "XXXX" is a computed column." }, How to resolve this. Is there any possibility that we can use the computed columns in the datatable for updating. If not is there any workaround for this.
Thanks in advance

If the computed columns are based on the data in your dataset, surely you can just put the computations into your update sql...

there is a good article here on CP somewhere.
Can't find it right away, but if you try several keywords you'll get there (also try MSDN)
(keywords you can try, dynamically create datagrid, datagrid at runtime, ...)
Coulda, woulda, shoulda doesn't matter if you don't.

I have a question about the Post Back, I dont think Ive really got it yet. I have a form with checkboxes and a submit button. I put in a break point in the page load method and my onClick method of the button. First time, page loads, grand. Checkbox values are populated from a DB grand. Then I change the values of the check boxes and click submit. The first breakpoint i encounter is the one in page load, which reloads the checkbox values from the DB and then these go into the onClick method. So my question is why is the order pageload, click submit, page load, onClick method? Ive tried putting the generation of the checkboxes in a if(!page,ispostback) but then in the submit method i call FindControl and it cant find them because I guess they were never created. What I want to know is why is this second pageload in there? I dont want it and its wrecking things. Thanks in advance,

You mean you want to place some settings in an external file, and refer to it from the web.config? If so, you can check out the file[^] attribute of the appSettings element.
