Hello. I was called to work on an older .NET legacy web app recently. The performance had recently fallen quite sub-par, as the amount of data in the system had quadrupled. Had been fine for the previous 2 years. It was using a .xsd file to talk to a stored procedure that narrowed the results sufficiently (though no paging) and feeding ...
I have a question related to this one. I don't want to do a calculation (aggregation), but I need to get display values from an association. In my C# code, I can directly reference the value, because the foreign key constraint made Linq generate all the necessary wiring. When I specify the IQueryable as the Gridview datasource property, ...

This is driving me crazy :-) I'm trying to get a ASP.NET 3.5 GridView to show a selected value as string when being displayed, and to show a DropDownList to allow me to pick a value from a given list of options when being edited. Seems simple enough? My gridview looks like this (simplified): <asp:GridView ID="grvSecondaryLocations" ru...

I choose not to display the primary key for user interface purposes, but require that key for basic operations on the grid.

[edit: apparently I'm wrong and parent is not null, weird stuff, is all.] Thing is, there is a checkbox representing a boolean state in relation to a user's relation to an ID. I have to update ...
