Container in Grid

[Kent]

I have problems while showing the content of the container in the grid.
My datasource has two field. First field is the id of type string and the second of type container.

Which problems do you have?
Stack trace or just wrong displaying?

I have problem with displaying. Axapta tray display it as image and I got an error. That is the problem.
I have code: I collect data from ListView and insert it in container, and container I post in table. 'Field' have extended data type "Container".

    container    con;
    Set          set = new Set(Types::String);
    ;

    idx = ListSelected.getNextItem(FormListNext::All);
    while (idx != -1)
    {
        item = ListSelected.getItem(idx);
        set.add(item.data());
        idx = ListSelected.getNextItem(FormListNext::All, idx);
    }
    con = [set.pack()];
    table.Field= con;
    table.insert();

After this, in table in container field I got this result: The question is - how to display this in Grid ?

[plumbum]

This is not a problem - system doesn't know how to display your container, that's why it populates it it the tree view.

This is redundant:

con = [set.pack()];
table.Field= con;

You need only this:

table.Field= set.pack();

As I can see you don't know for sure, how many rows you'll get selected in List view
If you want to display selected items in grid, you will have to create child table and join it with parent using specified key. Child table will contain records with selected list view items.
Also you can display rows, creating another list view or tree view, depending on what you need.

If you describe the purpose of displaying container in grid in detai, solution can be more obvious

I don't use child table, because I have more ListViews with different data. Example, I select 3 rows from ListView 1, and example 1 row from ListView2. And than I get in table following:

id     Field 1.....................Field2
1      ListView1<field>       
2      ListView1<field> 
3      ListView1<field>
4..................................ListView2<field>

If I have example 6 ListViews, this table looks terrible. Therefore I wanted post selected fields in containers, to insert all info in one row.

Maybe are different way to solve this?

May be convert your container to string with using function Global::con2str? And then use display method for showing result string in grid. Before showing result string can be arranged with some additional chars, just like LF, CR etc.

[plumbum]

You can provide table with the next structure:
Field 1 - Type of list view (enum), for instance, ListView1, ListView2
Field 2 - Value (string) - selected item text

Thank You plumbum and Gustav. I will try this ways.
