ItemDataBound主要是用来最后改变一次repeat在客户端加载的数据主要用来设置 ItemCommand主要是利用repeat的按钮控件的CommandName和CommandArgument
1.ItemCommand实例
protected void Repeater3_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "启用")//CommandName主要使前台代码和后台代码打交道
{
T_UsersTableAdapter adapter = new T_UsersTableAdapter();
long id= Convert.ToInt64(e.CommandArgument);//CommandArgument主要使后台与数据库打交道
adapter.AlterjiyongById(id);
Repeater3.DataBind();
}
else if (e.CommandName == "禁用")
{
T_UsersTableAdapter adapter = new T_UsersTableAdapter();
long id = Convert.ToInt64(e.CommandArgument);
adapter.AlterqiyongByID(id);
Repeater3.DataBind();
}
else {
throw new Exception("有错");
}
}
2. ItemDataBound实例
protected void Repeater3_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)//指触发对象的类型是DadaList里的基本行或是替换行（简单的说是Repeater里的所有数据项内容）
{
DataRowView drv = (DataRowView)e.Item.DataItem;
var row = (WebApplication1.ObjDateScr.DAL.DataSetPerson.T_UsersRow)drv.Row;
if (row.state == "禁用")
{
HtmlTableRow trRow = (HtmlTableRow)e.Item.FindControl("trRow");
trRow.Attributes["class"] = "trRow";//给<tr runat="server" class="trRow">的行添加属性
Button btn = (Button)e.Item.FindControl("disable");
btn.Visible = false;
Button btn2 = (Button)e.Item.FindControl("able");
btn2.Visible = true;
}
else if (row.state == "启用")
{
HtmlTableRow trRow = (HtmlTableRow)e.Item.FindControl("trRow");
trRow.Attributes["class"] = "";
Button btn = (Button)e.Item.FindControl("disable");
btn.Visible = true;
Button btn2 = (Button)e.Item.FindControl("able");
btn2.Visible = false;
}
else
{
throw new Exception("非法的状态");
}
}
}
