Hi !

How can I hide columns (properties) when I bind the collection to the grid. I have properties like ID or createUser, createDat. Where do i have to set those properties. I am new to llblgen. In mygeneration i just made new abstract classes. Can I change the entityclasses to set these properties using methods ? Your examples with the northwind are to easy. All columns used in the grid. No hidden columns with calculated values . Maybe you can give me a short example the best way doing this. How can I filter, sort the grid ? cancel update, undo a row ?

Thanks for your help.

Create a table style and only define a couple of columns. (doesn't work in infragistics, there you have to hide the columns manually) Sorting: set SupportsSorting to true and the grid will allow you to sort. Cancel update: press ESC.

Hi Otis,

when I try to bind a collection at design time to the datasource property of an infragistics grid, the columns will not show up!

The same with the standard grid, works!

What can I do?

Greetings Herwig

I noticed that too (at least in teh webgrid), and I have no idea why it doesn't work, I'm sorry.

Herwig: Are you using WinGrid or WebGrid? I have some experience with WinGrid and the entity collections...You won't be able to use the designer to bind the entity collection to the grid, but setting the datasource property of the grid to the entity colllection and calling DataBind() should work without a problem.

Jeff...

BTW,

The Infragistic grid will traverse the entire entity collection. To prevent this, set the MaxBandDepth to 1.

Hi Jeff,

I use both IG webgrid and the IG wingrid. The infragistics wingrid works perfectly, (MaxBandDepth set to 1) but the webgrid does not have any MaxBandDepth-option!

No solution yet!

Found it (I think). Try setting DisplayLayout->ExpandableDefault (in the designer) to "No". It prevents the grid from traversing the datasource, but there's an extra little box now to the left of the row selector boxes...
