DataSource Controls :: Getting Rows From Object Data Source?
Jan 7, 2010I have an object data source that is being used by an rdlc report, and the object data source uses a filter that is built from session variables passed to the page.
The report displays correctly, with the filter applied; however, I want to mark each of the rows as "printed" in a bit field in the database table.
In the table adapter, I have the following Update command that is used by the object data source:
UPDATE dbo.WorkOrder
SET boolWorkOrderPrinted = 'True'
WHERE (WorkOrderID = @Original_WorkOrderID)
And in the Page Load event, I run:
ObjectDataSource1.Update();
However, no records are updated.

DataSource Controls :: How To Use A Data Table As A SQLDataSource Control Source
Aug 4, 2010I know this sounds odd. I have a SQL DB that I am pulling data from. I have to some math functions to get a percentage. So I am pulling all the data in my code and building a data table with the results. I am then trying to pass this into a chart control that I have, but it fails because the data source is not correct for the chart control. I know that the chart control will accept a SQLDataSource control as a data source because a built a example with it before using it in my project.So my question is how can I use the Data Table as a data source for a SQLDataSource Control? Or is there a way I can pull the data from my DB andapply the math needed in a stored procedure or something similar that I could create the procedure on my SQL server then add a SQLDataSource control to my page and use the stored procedure as the source for the SQLDataSource Control.
