I have used the code below in the past to sort a data grid column. Now I'm
using a SqlCeResultSet as my DataSource for the grid.



Since the SqlCeResultSet is new to me I was hoping someone could point out
what needs to be converted to support using a resultset instead of a
DataTable.



Thanks!



// Sort grid by column
void SortGrid(int col)
{


if (this.DataSource is DataTable)
this.DataSource = (this.DataSource as
DataTable).DefaultView;


DataView vw = (DataView)this.DataSource;
string sort = vw.Table.Columns[col].ColumnName;

if (vw.Sort.StartsWith(sort))
{
if (vw.Sort.EndsWith("ASC"))
vw.Sort = sort + " DESC";
else
vw.Sort = sort + " ASC";
}

else
{
vw.Sort = sort + " ASC";
}
}

You can not sort/filter RS. You have to get new sorted/filtered RS using
respective SQL query and bind it to the grid.

Don't forget to dispose of an old RS.

Jen,

The ResultSetView, unlike the DataView, does not expose a Sort member, but
does implement the IBindingList interface and exposes an ApplySort method

which you could implement. Sorry I don't have a sample of that handy, but

there are examples of implementing ApplySort on the web.
