这句什么意思？？
this.mygridview.DataSource = "数据源"；
this.mygridview.DataBind();
是这样的，不好意思啊。
string mysql = "select * from table1 where 价格 = "+myaaa;
SqlConnection myconnection = new SqlConnection();
myconnection.ConnectionString = @"data source=.\sqlexpress;attachdbfilename=|datadirectory|\mydb1.mdf;integrated security=true;user instance=true";
var mysss = new SqlDataAdapter(mysql,myconnection);var myvvv = new DataSet();
int counter = mysss.Fill(myvvv, "mytab");mygridview.DataSource = myvvv.Tables["mytab"];
然后是这段代码：
this.mygridview.DataBind();
就可以了吧。
{
if(!IsPostBack)
BindData();
}
protected void mygridview_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
mygridview.PageIndex = e.NewPageIndex;
mygridview.datasource="数据源";
mygridview.DataBind();
}
可使用aspnetpager控件
}
private GridViewDataBind()
{
string myaaa=Request.Form("价格");
string mysql = "select * from table1 where 价格 = "+myaaa;
SqlConnection myconnection = new SqlConnection();
myconnection.ConnectionString = @"data source=.\sqlexpress;attachdbfilename=|datadirectory|\mydb1.mdf;integrated security=true;user instance=true";
var mysss = new SqlDataAdapter(mysql,myconnection);var myvvv = new DataSet();
int counter = mysss.Fill(myvvv, "mytab");mygridview.DataSource = myvvv.Tables["mytab"];this.mygridview.DataBind();
}
然后在
protected void Page_Load(object sender, EventArgs e)
{
GridViewDataBind()；
}
protected void mygridview_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
this.mygridview.PageIndex = e.NewPageIndex;
GridViewDataBind()；
}
全部程序如下。请帮看下。如果不分页是没问题的。分页就提示(在 'and' 附近)中指定了非布尔类型的表达式。（不点击分页可以正常使用的)（程序很差，别笑话我）.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
binddata();
}
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
binddata();
}protected void binddata()
