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:

复制代码 代码如下:
protected void page_load(object sender, eventargs e)
{
        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:

复制代码 代码如下:
protected void repeater1_itemcommand(object source, repeatercommandeventargs e)
{
        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());
        }
}
