How to let the cellvalue not changed together when scrolling the wheel of the mouse
posted

There is an ultraGrid(named ultraGrid1) and an ultrDropDown(named DDHeadType), the WSHeadTypeNo column's valus is from DDHeadType, now when in the editmode, when I scroll the wheel of the mouse, How to let the data of the WSHeadTypeNo cell in the ultrGrid not to change together? (below   a little code  to explain the relation and data)

this.DDHeadType.DataSource = datatableDheadtype

  this.ultraGrid1.DisplayLayout.Bands[0].Columns["WSHeadTypeNo"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownValidate;
  this.ultraGrid1.DisplayLayout.Bands[0].Columns["WSHeadTypeNo"].ValueList = this.DDHeadType;

 

 

How to realize it?  Thanks in advance!

    I think you want to handle the MouseWheel event, upcast the MouseEventArgs to HandledMouseEventArgs, and set the Handled property to true. This will prevent the default mouse wheel processing.
