Hi,
ive got a table with these columns
ID,jobid,description,StartTIme and EndTime.

Then I created a stored procedure to return these fields + a calculated column to display the difference in hours from the StartTime and EndTime columns. This column is called TotalHrs.

In my objectdatasource, in the select list, i ve choosen this stored procedure. And in the UPDATE list i selected a stored procedure, that i created, to update those fields ( In the update procedure doesnt appear the column TotalHrs)

Now, the grid it is showing me the correct data with the difference in hours but when i try to update the record it says.( In this grid I added a template field to show the total hours bound to the stored procedure field TotalHrs)

"ObjectDataSource 'ods_timesheet' could not find a non-generic method 'spUpdateTimeSheet' that has parameters: JobID, Description, StartTime, EndTime, original_ID, totalhrs"

If i remove the template field 'TotalHrs' it updates fine.

any thoughts?

i found the answer.

I went back to the XSD file I added an extra column, in this case TOTALHRS.
Then i refreshed my objectdatasource to make the field 'TotalHrs' appear in the bound field list. SO after this, i made it Readonly = true and that worked.
