Windows Datagrid Column Sorting

[Carl Tribble]

After a user has clicked a column header to sort, how can I tell which
column header he clicked? In other words, how can I tell what order the
list is in after user changes it by clicking a column header?

Thanks,

Hey Carl,

the way this actually works is that when you bind to a datatable/dataset the
grid actually binds to the DefaultView property of the datasource. So, when
you click on the clolumnheaders, the sort property of this underlying
DefaultView is reset (based on which header you click).

that is the long of it just to give you an understanding of how the datagrid
works...

the short answer is to use the bindingcontext. something like...

ctype(me.myData Grid.BindingCon text(myGridsDat aSourceTable).C urrent,
DataRowView).Ro w

this line will get you the actual datarow that is currently selected in the
grid, regardless of the sort. (beware typos, it's late...)

hope this helps,

jim

If you want to know which column is sorted, I think you can retrieve the
dataView.Sort property for the DataView associated with your datagrid. You
can get this dataview through the CurrencyManager .

Dim cm as CurrencyManager =
CType(Me.DataGr id1.BindingCont ext(Me.DataGrid 1.DataSource,Me .DataGrid1.Data M
ember), CurrencyManager )
Dim dv as DataView = CType(cm.List, DataView)
' dv.Sort should hold the sorted column(s)

Thanks Clay, that is exactly what I was looking for.

Thanks also to Jim, your input was useful too.

I have only been using this newsgroup a short time, but I love it!
