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：
[b]repeater绑定数据：
[/b]
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();
}
}
}
[b]删除数据：
[/b]
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());
}
}
[b]前台：
[/b]
