Question

求教ASP.NET里 datalist的问题

 protected void dgList_ItemDataBound(object sender, DataListItemEventArgs e)    {        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)        {            HiddenField hidInfoTypeID = (HiddenField)e.Item.FindControl("hidInfoTypeID");            DataList dgInfoView = (DataList)e.Item.FindControl("dgInfoView"); 求高手每行注释一下。尤其object sender datalistitemeventargs e那点

Answer 1

//这里没办法解释，请自己看“C#事件处理”相关资料
protected void dgList_ItemDataBound(object sender, DataListItemEventArgs e)
{
//判定行类型是否是数据行 以及 交错行
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//查找行内ID为 hidInfoTypeID 的HiddenField控件
HiddenField hidInfoTypeID = (HiddenField)e.Item.FindControl("hidInfoTypeID");
//查找行内ID 为 dgInfoView的datalist，这里看样子是一个嵌套的datalist
DataList dgInfoView = (DataList)e.Item.FindControl("dgInfoView");
｝
