title: Unable to select multiple rows on infragistics ultrawingrid with a check box column
body: <p>I am having below code that successfully adds a check box column to the ultrawingrid, my problem is that when I make a selection by checking a check box on the Select column the count of selected rows of ultrawingrid is not updated and it still shows the count as zero, and also I want to know how to enable multi checkbox selection i.e multiple rows selected...</p>
  
  <p>Below is the code...</p>
  
  <pre><code>private void grdPayVis_InitializeLayout(object sender,InitializeLayoutEventArgs e) 
   var gridBand = grdPayVis.DisplayLayout.Bands[0]; 
      if(!gridBand.Columns.Exists("Select"))
      gridBand.Columns.Add("Select", "Select");
  gridBand.Columns["Select"].Header.VisiblePosition = 0; 
  gridBand.Columns["Select"].Hidden = false; 
  gridBand.Columns["Select"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.CheckBox; 
  gridBand.Columns["Select"].AutoSizeMode = ColumnAutoSizeMode.AllRowsInBand; 
  gridBand.Columns["Select"].CellClickAction = CellClickAction.Edit; 
  </code></pre>
