示例1: SetFormItemListControl
/// <summary>列表框</summary>
/// <param name="entity"></param>
/// <param name="field"></param>
/// <param name="control"></param>
/// <param name="canSave"></param>
protected virtual void SetFormItemListControl(IEntity entity, FieldItem field, ListControl control, Boolean canSave)
{
if (control.Items.Count < 1 || !String.IsNullOrEmpty(control.DataSourceID))
{

// 这个赋值会影响RequiresDataBinding，而RequiresDataBinding会导致列表控件在OnPreRender阶段重新绑定，造成当前设定的值丢失。
//control.AppendDataBoundItems = false;
}
if (control.Items.Count < 1) return;
String value = String.Empty + entity[field.Name];
try
{
control.SelectedValue = value;
if (control.GetType() == typeof(DropDownList) || control.GetType() == typeof(ListControl))
{
/*
* 对于ListControl和DropDownList,仅PostBack时有可能抛出异常,初次打开有可能在PerformDataBinding中抛出异常,所以要做额外检测
*
* 因为DropDownList.SelectedIndex get时有可能修改Items[0].Selected, 所以下面代码最好避免访问SelectedIndex,SelectedValue
*
* 对于XControl.DropDownList始终没问题
* */
