public class ColumnTemplate : ITemplate
{
   private string strControlType,strControlID,strColumnName;
   
public ColumnTemplate (string ControlType,string ControlID,string ColumnName)
      {
            
         this.strControlType=ControlType;
this.strControlID=ControlID;
this.strColumnName=ColumnName;
       }
    public void InstantiateIn(Control container)
    {
        switch(strControlType.ToLower())
         {
   case "checkbox":
                     CheckBox checkbox=new CheckBox();
                     checkbox.ID=strControlID;
                     checkbox.DataBinding+=new System.EventHandler(OnDataBinding);
                     container.Controls.Add(checkbox);
                     break;   case "label":
                     Label label=new Label();
                     label.ID=strControlID;
                     label.DataBinding+=new System.EventHandler(OnDataBinding);
                     container.Controls.Add(label);
                     break;
default:
     break;
}
    }
private void OnDataBinding(object sender,EventArgs e)
        {
            DataGridItem container;
            switch(strControlType)
            {
                case "label":
                    Label label;
                    label=(Label)sender;
                    //控件发送绑定请求 
                    container=(DataGridItem) label.NamingContainer;
    label.Text=(DataBinder.Eval(container.DataItem,strColumnName)).ToString();
                    break;
case "checkbox":
                    CheckBox checkbox;
                    checkbox=(CheckBox)sender;
                    //控件发送绑定请求 
                    container=(DataGridItem) checkbox.NamingContainer;
                    checkbox.Checked=(bool)((DataRowView)(container.DataItem))[strColumnName];
                    break;
default:
    break;
   }
}
