Infragistics UnboundCheckBoxField

Infragistics WebDataGrid重新绑定数据时，All Selection不听使换：

设置：UnboundCheckBoxField HeaderCheckBoxMode="TriState"

cs添加：

((Infragistics.Web.UI.GridControls.UnboundCheckBoxField)this.wdgOrder.Columns["chkSelect"]).HeaderChecked = false;

Html:

<ig:UnboundCheckBoxField HeaderChecked="False" HeaderCheckBoxMode="TriState" Key="chkSelect" Width="15">

Code Behind:

this.wdgOrder.ClearDataSource();

this.wdgOrder.DataSource = ds.Tables[0].DefaultView;

((Infragistics.Web.UI.GridControls.UnboundCheckBoxField)this.wdgOrder.Columns["chkSelect"]).HeaderChecked = false;
