Primary key problem for tables
posted

I have an application that has parent and child tables.  The user selects a shipping terminal and clicks GO to display a list of workers and their information.  The hierarchy goes down three levels.  Terminal Summary - Worker Summary - Worker Detail.  The application always works fine on the first pass.  But when the user changes terminals the application always returns the following error "Table (tablename) doesn't contain a row with the specified PrimaryKey value" on the following line of code:

whdg.ExpandAll()

Any help will be greatly appreciated.

Thanks

    Hi Joseph,

    Are you changing the WHDG’s datasource when the user picks a new terminal?

    If you are not changing the datasource try calling Clear() on the GridView’s Rows, right before you assign a new datasource.  Whdg.GridView.Rows.Clear(); That may fix the issue.  If that does not fix the issue you are seeing, can you provide a small sample that functions similarly to your application (using some made up datasources).

    Thank You,
