ASP.NET中repeater控件用法实例
本文实例讲述了asp.net中repeater控件用法。分享给大家供大家参考。具体实现方法如下：
repeater绑定数据：
{
if(!ispostback)
bindstudent();
}
private void bindstudent()
{
string str = configurationmanager.connectionstrings["stucnn"].connectionstring;
using (sqlconnection sqlcnn = new sqlconnection(str))
{
using (sqldataadapter da = new sqldataadapter("select * from student", sqlcnn))
{
dataset ds = new dataset();
da.fill(ds);
this.repeater1.datasource = ds;
this.repeater1.databind();
}
}
}
删除数据：
{
if (e.commandname == "delete")
{
string str = configurationmanager.connectionstrings["stucnn"].connectionstring;
using (sqlconnection sqlcnn = new sqlconnection(str))
{
using (sqlcommand sqlcmm = sqlcnn.createcommand())
{
sqlcnn.open();
sqlcmm.commandtext = "delete from student where sid="
+ e.commandargument.tostring();
sqlcmm.executenonquery();
}
}
this.bindstudent();
}
else if (e.commandname == "edit")
{
server.transfer("edit.aspx?sid=" + e.commandargument.tostring());
}
}
