Sorting & BindingContext

[Guest]

I have a DataGrid (DG) and adjacent TextBoxes (TB) that are all bound to the
cells of the DG. If you move the DG row left indicator (arrowhead) the TB's
update to agree with the row of the DG. All this is done with the
CurrentCellChanged() event

However, if I sort a DG column (allowsorting == true), the TB's don't
update with the new data of that sorted row (I have to reselcted a different
row to rebind). So, when I sort a DG column, the TB still show the data for
that previous row location

How can I solve problem?

There may be an easier way, but one way I did this was to create a hash
table with the position of each row as it comes in originally and the key
value. THen I could always use that original position after I sorted to
find whatever record I wanted by setting the BindingContext's position to
it. DataBinding isn't my strong suit so there is probably a more
elegant/simple way to do it, but in a pinch I know this will work.

Steve,

Probably are you missing the knowledge of the currencymanager. That manages
not money, however the current position in the datatables (as well using
dataviews)

I hope this helps,
