Hello,

 I'm populating an UltraWinGrid with a DataSource:

sourceDataTable = new DataTable("Client");
OleDbDataAdapter adaptation = new OleDbDataAdapter("select * from Client", strConn);
adaptation.Fill((System.Data.DataTable)sourceDataTable);

this.SuspendLayout();
((System.ComponentModel.ISupportInitialize)(this.memberGrid)).BeginInit();
 this.memberGrid.DataSource = ((System.Data.DataTable)sourceDataTable);
((System.ComponentModel.ISupportInitialize)(this.memberGrid)).EndInit();
this.ResumeLayout(false);

And then immediately afterwards, I want to group by a particular column:

this.memberGrid.DisplayLayout.Bands[0].SortedColumns.Add("Surname", false, true);

This fails. My debugger shows that this.memberGrid.Rows.Band.Columns.Count evaluates to 0. However, after some "time", the UltraWinGrid is succesfully populated by the the datasource.

How can I force the UltraWinGrid to be populated by the DataSource? Is there something that I'm forgetting?

 Thanks in advance,

Indika
