}

public System.Data.DataSet ds(string Sql,string TableName)

SqlConnection MyConnection = CreateCon();
MyConnection.Open();
SqlDataAdapter MyCommand=new SqlDataAdapter(Sql,MyConnection);
DataSet ds=new DataSet();//定义一个数据集
MyCommand.Fill(ds,TableName);

}

这个绑定不了数据，什么原因呀！
我知道应该是字段问题，但应该怎么修改呢！希望各位大哥能相助!!!

DataGrid的相关操作

++++++++++++++++++++++++++datagrid绑定显示数据+++++++++++++++++++++++++++++++++
/*
============方法一===============================================
this.SetDataGridStyles("temp",this.dataGrid1);
this.dataGrid1.DataSource=ds;
this.dataGrid1.DataMember="temp";

this.SetDataGridStyles("temp",this.dataGrid1);
this.dataGrid1.SetDataBinding(ds.Tables["temp"].DefaultView,"");
============方法三=================================================
this.SetDataGridStyles("temp",this.dataGrid1);
this.dataGrid1.DataSource=ds.Tables["temp"].DefaultView;

this.SetDataGridStyles("temp",this.dataGrid1);

这个，我咋找不到呢？

SetDataGridStyles

一个函数，下面有，自己去研究吧

++++++++++++++++++++++++++++定制显示列datagrid++++++++++++++++++++++++++++

pageLoad下

if(!ispostback)
{
BindData();
}

建议把SQL语句创建一个试图，然后在帮顶 。最后要问一句那个上面的bs是怎么来的
GridView1.DataSource = bs.ds("SELECT A.newID, A.title, B.type, B.newID AS Expr1, B.Pconent,B.Pid B.Ptime, B.Pname, B.pIP FROM dbo.tb_new A INNER JOIN dbo.tb_pingl B ON A.newID = B.newID", "pinglun");

应该改为这样不更好GridView1.DataSource = ds("SELECT A.newID, A.title, B.type, B.newID AS Expr1, B.Pconent,B.Pid B.Ptime, B.Pname, B.pIP FROM dbo.tb_new A INNER JOIN dbo.tb_pingl B ON A.newID = B.newID", "pinglun");直接绑？
最后按楼上的这个大哥说的这样帮顶在load中
pageLoad下

if(!ispostback)
{
BindData();
}

SELECT A.newID, A.title, B.type, B.newID AS Expr1, B.Pconent,B.Pid B.Ptime, B.Pname, B.pIP FROM dbo.tb_new A INNER JOIN dbo.tb_pingl B ON A.newID = B.newID

这是我创建视图后,跑出来的!

不知道这么调用视图,所以就直接放出代码里了!

好象不能直接绑定吧!

倒......
你创建一个试图名啊.哎......然后直接插入一句试图语句就可以了啊
然后在调用这个方法啊
pageLoad下

if(!ispostback)
{
Binddata();//这个方法是你自己写的那个啊
}

楼主啊。bs.ds("SELECT A.newID, A.title, B.type, B.newID AS Expr1, B.Pconent,B.Pid B.Ptime, B.Pname, B.pIP FROM dbo.tb_new A INNER JOIN dbo.tb_pingl B ON A.newID = B.newID", "pinglun");传回来的是一个DataSet,不是一个DataTable
建议：先定义一个DataSet来接收这个方法传回的值，再去绑定 .DataSource=DS.Table[0];

这个与是DataSet,DataTable有什么大的关系嘛?

其它的,我都是用dataset绑定的,这次我只是加了tb_new A ,tb_pingl B .才显示有问题!

我想应该是他对字段不认识吧!
