GGC: Delay when adding relation before new columns are available

[Sigurd Ringbakken]

I''m having trouble when trying to access columns that are added to my table through a ForeignKeyReference-relation.

Example:
I add a relation to a child table containing the field "Message". The relation is named "rel".

//Add relation
myGrid.TableDescriptor.Relations.Add(myRel);

//Remove all visible columns
myGrid.TableDescriptor.VisibleColumns.Clear();

if( myGrid.TableDescriptor.Columns.Contans("rel_Message") )
{
myGrid.TableDescriptor.Columns["rel_Message"].HeaderText = "Message";
myGrid.TableDescriptor.VisibleColumns.Add("rel_Message");
}

If I put a break-point in the first line and steps over it, the new column is added and available in the TableDescriptor.Columns - collection. If I don''t put a breakpoint there, the column is not available immediately.

What is the solution to this problem?

After adding the columns, try setting

this.gridGroupingControl1.Table.CountersDirty = true;

to see if that takes care of this problem.

Unfortunately it didn''t.
Same behaviour.

Does calling
myGrid.TableDescriptor.Columns.LoadDefault()

help?
