Disable datagrid sorting

[Mike]

Hi,

I would like to disable sorting in a winform datagrid when a column header
is clicked.
The following does *not* seem to disable sorting and clicking the column
header still sorts the grid:

After loading data into the dataset:

{
....
this.dataGrid1. DataSource = this.ds1.tableA ;

System.Data.Dat aView dv = this.ds1.tableA .DefaultView;

dv.AllowNew = false; // no append row

dv.AllowDelete = false; // no delete row

dv.Sort = ""; // no sort string <------- ????

dv.ApplyDefault Sort = false;

....

}
Also in the mouse down/up events:

{

....

Point pt = new Point(e.X, e.Y);

DataGrid.HitTes tInfo hti = dataGrid1.HitTe st(pt);

if( hti.Type == DataGrid.HitTes tType.ColumnHea der )

return; // don't sort: don't call baseclass !!!

base.OnMouseUp( e); // ... or OnMouseUp
}
Thanks in advance

Have you set the AllowSorting property in the DataGrid class to false ??
e.g.

this.dataGrid1. DataSource = this.ds1.tableA ;
this.dataGrid1. AllowSorting = false;
System.Data.Dat aView dv = this.ds1.tableA .DefaultView;
....
....
....

Hope it helps,
