请问为什么DataGrid修改后刷新不了?

[life923]

Button1_Click修改后刷新不了数据,要点击浏览器的刷新 ,数据才会更新
protected void Page_Load(object sender, EventArgs e)
{

if (!Page.IsPostBack)
{
BindGrid();
}


}
private void BindGrid()
{

String conn_str = "provider=Microsoft.Jet.OLEDB.4.0;Data Source="
+ Server.MapPath("../") + Constants.conn_string;
String sql = "select count(*) from [reg] ";
OleDbConnection conn = new OleDbConnection(conn_str);
conn.Open();
OleDbCommand cmd = new OleDbCommand(sql, conn);
this.Pager.RecordCount = (int)cmd.ExecuteScalar();
int pageIndex = this.Pager.CurrentPageIndex - 1;
int pageSize = this.Pager.PageSize = 20;
int firstPage = pageIndex * pageSize;

sql = "select * from [reg] order by regdate desc";
cmd = new OleDbCommand(sql, conn);
DataSet ds = new DataSet();
OleDbDataAdapter dataAdapter = new OleDbDataAdapter();
dataAdapter.SelectCommand = cmd;


dataAdapter.Fill(ds, firstPage, pageSize, "kk");
DataGrid.DataSource = ds.Tables["kk"];
DataGrid.DataBind();
}

protected void Button1_Click(object sender, EventArgs e)
{
String conn_str = "provider=Microsoft.Jet.OLEDB.4.0;Data Source="
+ Server.MapPath("../") + Constants.conn_string;
OleDbConnection conn = new OleDbConnection(conn_str);
conn.Open();
String sql = "update [reg] set [level]='11' where [uusername]='22' ";
OleDbCommand cmd = new OleDbCommand(sql, conn);
cmd.ExecuteNonQuery();

BindGrid();

}

[程序漫步]

if (!Page.IsPostBack)
{
BindGrid();
}
这个的问题！

[life923]

还是不行啊

设置断点..看看BindGrid()函数会不会跑进去

[mengxj85]

有点怪
protected void Button1_Click(object sender, EventArgs e)
{
String conn_str = "provider=Microsoft.Jet.OLEDB.4.0;Data Source="
+ Server.MapPath("../") + Constants.conn_string;
OleDbConnection conn = new OleDbConnection(conn_str);
conn.Open();
String sql = "update [reg] set [level]='11' where [uusername]='22' ";
OleDbCommand cmd = new OleDbCommand(sql, conn);
cmd.ExecuteNonQuery();

BindGrid();

}
跟踪BindGrid()看看

你里面写的代码我没看,只看方法就是那样的了.
不行的话你就写句这吧:

 if (.......)
        {
            ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "onclick", "location.href='../Index.aspx';", true);
        }

你的问题说的不是很详细 ，建议 BindGrid()方法
加个断点 或者些个javascriot测试一下！

去掉if (!Page.IsPostBack) 后

我页面的DropDownList值,选择后不会改变
Request["chkSelect"]; 还是初始值啊

[tong_xing]

BindGrid()函数试一下！

把if (!Page.IsPostBack) 去掉

[Adechen]

去掉if (!Page.IsPostBack)
让页面每次加载时bind下grid
