DataBind to current row of a datagrid

Hi all

As DataGrid is readonly I decided to add an UpDown control to the bottom of
my form in order to allow the user to edit a numerical value of the selected
row.

I have done this in code, but I suspect that there must be a way to do this
via databinding. So my question is this, how can I databind the Value
property of my UpDown control to the CurrentRow.RecordedAmount, but when the
selected row changes the UpDown will be editing the newly selected row
instead?

Thanks

Pete
 
Peter,

I don't know of a way to do this automatically using data binding. Since you
have a coded solution already, I'd just go with that. It will give you more
control than an "automatic" one would if it were available anyway.
 
In fact this scenario is automatically handled by CurrencyManager class in
data binding engine.

If you have DataTable bound to the grid and bunch of simple controls bound
to the same DataTable, CurrencyManager would bind simple controls to the
current row in the grid.



So, there's nothing to code besides setting up bindings like this:



dataGrid.DataSource = dataTable;

upDown.Bindings.Add("Value", dataTable, "RecordedAmount");



Best regards,

Ilya

Thanks, Ilya. I misread what he wanted to do and thought he wanted to change
the selected row in the grid based on the up/down control. But in any case,
as long as he has a working solution...
 
Ah, I can databind to the datagrid then? I will try that, thanks!
