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" + e.CommandArgument.ToString());
        }
}

前台：
复制代码代码如下:<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

        <asp:Repeater ID="Repeater1" runat="server"
            onitemcommand="Repeater1_ItemCommand">
        <HeaderTemplate><table>
        <tr><td style="width:100px">编号</td><td style="width:100px">姓名</td>
        <td style="width:100px">图片</td><td> </td><td> </td></tr>
        </HeaderTemplate>
        <ItemTemplate>
        <tr>
        <td><%# Eval("sid") %></td><td><%# Eval("sname") %></td>
        <td><img width="60px" height="60px" src='<%# "images/" + Eval("photo") %>' /></td>
        <td><asp:LinkButton ID="btnDelete" runat="server" Text="删除" CommandName='Delete' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td>
        <td><asp:LinkButton ID="btnEdit" runat="server" Text="编辑" CommandName='Edit' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td>
        </tr>
        </ItemTemplate>
        <AlternatingItemTemplate>
        <tr style="
        <td><%# Eval("sid") %></td><td><%# Eval("sname") %></td>
        <td><img width="60px" height="60px" src='<%# "images/" + Eval("photo") %>' /></td>
        <td><asp:LinkButton ID="btnDelete" runat="server" Text="删除" CommandName='Delete' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td>
        <td><asp:LinkButton ID="btnEdit" runat="server" Text="编辑" CommandName='Edit' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td>
        </tr>
        </AlternatingItemTemplate>
        <SeparatorTemplate>
        <tr><td colspan="5"><hr /></td></tr>
        </SeparatorTemplate>
        <FooterTemplate></table></FooterTemplate>
        </asp:Repeater>

</div>
</form>
</body>
</html>

启用，禁用：
复制代码代码如下:protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
        //string status = e.CommandName;
        if ((e.CommandName == "true")||(e.CommandName == "false"))
        {
            string str = ConfigurationManager.ConnectionStrings["stucnn"].ConnectionString;
            using (SqlConnection sqlCnn = new SqlConnection(str))
            {
                using (SqlCommand sqlCmm = sqlCnn.CreateCommand())
                {
                    sqlCnn.Open();
                    sqlCmm.CommandText = "update student set status=@status where sid="
                        + e.CommandArgument.ToString();
                    sqlCmm.Parameters.AddWithValue("@status",e.CommandName);
                    sqlCmm.ExecuteNonQuery();
                }
            }
            this.BindStudent();
        }
}

            onitemcommand="Repeater1_ItemCommand">
        <HeaderTemplate><table><tr><th>编号</th><th>姓名</th><th>状态</th><th> </th></tr></HeaderTemplate>
        <ItemTemplate>
        <tr><td><%# Eval("SID") %></td>

        <FooterTemplate></table></FooterTemplate>
        </asp:Repeater>
    </div>
