What do I have to do so that a property will show at the datasource?

This is a windows forms question. forgive me if I explain what I do with too much detail but I asked with less detail before and it seems nobody read, because answers were completely off mark and I wasted bouty.

I have a Linq object called XX. It was created when I dropped my table on the .dbml file in visual studio.

Then, to make my interfaces easier to program I go to Data->Show Data Sources on visual Studio and create a object data source. All properties of the object appear at the data source.

But the linq class is partial, so i do:

partial class XX
{
    private int _myValue;
    public int myValue
    {
        get { return _myValue; }
        set { _myValue = value; }
    }
}

are you following so far ?

Then i go and recreate the object data source.

The property myValue does not show on t开发者_Go百科he data source.

I tried decoratin it like this:

        [Bindable(true)]
        public int myValue

to no avail. This usualy does the trick for "non-linq" Plain classes.

So, the question is: What do I have to do so my property will show at the data source ?
