I have a quick question about sorting a dataset. I have created a query:
Select top 10 * from authors I have put the results of this query into a
dataset and bound that to a datagrid. I have also enabled the AllowSorting
property on the datagrid. What I have done for sorting is appended "order
by table" with the corresponding table to my original query when the
sortcommand event is fired. However, this executes a brand new query and
returns a different set of data from the db. How can I sort the original
dataset based upon one of the columns being selected?
Thanks.

Instead of binding to the DataSet, create a DataViewManager for the DataSet
and bind to that. You can apply sort orders for each table in the DataSet
(via their corresponding DataView) using the DataViewSettings collection of
the DataViewManager. For example...
DataViewManager myDVM = new DataViewManager(myDS);
foreach (DataViewSetting myDVS in myDVM.DataViewSettings)
myDVS.Sort = "Name";
myGrid.SetDataBinding(myDVM, "RootTable");
Note, for single table binding, you can simply use a DataView instead of a
DataViewManager.

Thanks this works great. I knew there had to be a way that I could do this
and avoid doing it manually.
