Sry for the double post my bad (u can remove the other thread),

I looked into the samples and came accross something i  was looking for:

Solution: WebgridSamples > BatchUpdate_CustomObjectUpdate.aspx

I can use codebehind to bind the webgrid to and datasource, however again select query's work fine but when i want to insert/update/delete it gives errors.

I am now trying to insert a record from  an intersoftgrid into an oracle table.  This method looks more likely to work but im getting errors so maybe im doing something wrong ? 

I have added some screenshots. the most important SS is Insert Method for(Webgrid) there  I show the error message with some text. The other screenshots are for additional information to understand my situation.
