Close, here's my Sort Proecdure:
Private Sub DataGrid1_SortCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridSortCommandEvent Args) Handles
DataGrid1.SortCommand
Dim dtParam As DataTable = DsChanges1.Tables(0)
dvwParam = dtParam.DefaultView
dvwParam.Sort = e.SortExpression
DataGrid1.DataSource = dvwParam
DataGrid1.DataBind()
End Sub
dvwParam is a dataview that binds to the above datatable
(dtparam.defaultview) as above. So, whenever I actually click on one of the
datagrid1's headhers to sort by that column it sorts just fine, but if I
click on a record, it gives the 'original' value (presorted record) not the
now-sorted-value (record).
The sub that's called when I click on a record is:
Private Sub DataGrid1_EditCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs ) Handles
DataGrid1.EditCommand
'This should be the value of the cell(1) a.k.a. Primary key value
"Change_ID" in the datagrid
propChange_ID = CType(e.Item.Cells(1).Text, String)
'Pass this ID to the Details form
Server.Transfer("frmChange_Details.aspx")
End Sub
I hope this makes sense. It looks like although the dataview is getting
sorted (which makes it appear the datagrid is sorted as well) the underlying
data table (or whatever is underlying to a dataview/grid) isn't being sorted
which is what my 'DataGrid1_EditCommand' is pointing to.

I'm assuming you are doing something like this....
yourObj.View.Sort = this.dataGrid1.SortOrder;
this.dataGrid1.DataKeyField = "PrimaryKeyFieldName";
this.dataGrid1.DataSource = yourObj.View;
this.dataGrid1.DataBind();
?

I've set a DataKeyField in the binding but when I click on a datagrid
item after a sort it still returns the wrong value. Does it matter that I'm
sorting using a dataview of the datagrid?

news:ue**************@tk2msftngp13.phx.gbl... make sure to set a DataKeyField in the binding, then use
myValue = dataGrid1.DataKeys[this.dataGrid1.SelectedIndex].ToString();
