Hiya,

I know that you can edit the columns in an entityCollection when it's bound to a datagridView at design time.

Is it possible to do the same in code / in the LlblgenPro designer?

many thanks,

You can't hide fields for an entity collection in the designer like you would for a datagrid, but you can make typedlist that will only contain the fields you would want to display.

You can also map another entity on the same table and remove fields from that entity from the list of fields.

hiya,

As usual with me, there's a twist :-(

the datagridView contains a column "productConditionId", I want to remove this column, and simply keep the lookup column ("productConditionName"), that I added in the LlblGenpro designer.

The problem: I have a combobox whose selected item is used as a predicate for the entityCollection.

TblReturnProductConditionEntity selectedCondition = (TblReturnProductConditionEntity)cboReturnProductCondition.SelectedItem;
            filtReturnProductCondition.Add(PredicateFactory.CompareValue(TblReturnProductsFieldIndex.ReturnProductCondtionId, ComparisonOperator.Equal, selectedCondition.ReturnProductCondtionId));        

            tblReturnProductsCollection1.GetMulti(filtReturnProductCondition);      

So, how can I:

a) hide the "productConditionId" column in the datagridView? b) yet STILL use this field as a predicate?

many thanks,

yogi

Have you tried setting the visible property of the productConditionId column to false? This column would then still be available, but not shown to your users.

hiya Brian,

the problem is that the entityCollection is bound to the datagridView in code, not via the designer.

Any ideas? thanks,

yogi

use a tablestyle which you design in the grid, or through code (though I'd use the grid's designer) and in there make sure the columns are in the right order, and hide columns there.

right,

This might sound like a stupid question, but how do i get access to a winforms datagridView "tableStyle" at design time?

Obviously, the datagridView doen't contain any columns at design-time, as it gets bound at run-time.

Many thanks,

yogi

Just add a collection to the form and use that to design the grid. You can bind any collection at runtime

hiya,

you're right, I don't know why I ever thought I needed to databind at runtime. ta,

yogi
