如何在下面加一个分页的功能？
[解决办法]
加一个控件
<webdiyer:AspNetPager ID="AspNetPager1" runat="server"
onpagechanged="AspNetPager1_PageChanged">
</webdiyer:AspNetPager>
后台代码：
if (!IsPostBack)
{
//绑定菜单类别
ax09_dishCatesBll bll = new ax09_dishCatesBll();
ddlcate.DataSource = bll.GetCates();
//显示的文本字段
ddlcate.DataTextField = "dishcate_name";
//隐藏的值字段
ddlcate.DataValueField = "dishcate_id";
ddlcate.DataBind();
//增加请选择项
ddlcate.Items.Insert(0, new ListItem("--请选择--", ""));
Bind();
}
}
private void Bind()
{
//获取查询条件
string cateid = ddlcate.SelectedValue;
string name = txtname.Text;
if (Check_Request(name))
{
MsgBox("提交的数据中包含危险字符，请重新输入！");
return;
}
string isshow = ddlshow.SelectedValue;
ax09_dishesBll dbll = new ax09_dishesBll();
//获取当前页数据
Repeater1.DataSource = dbll.GetDishes(AspNetPager1.CurrentPageIndex, 10, cateid, name, isshow);
Repeater1.DataBind();
//设置页码控件
AspNetPager1.RecordCount = dbll.GetCount(cateid, name, isshow);
AspNetPager1.PageSize = 10;
AspNetPager1.DataBind();
}
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
Bind();
}
protected void btnSearch_Click(object sender, EventArgs e)
{
//将页码设置为1
AspNetPager1.CurrentPageIndex = 1;
Bind();
}
