datagrid查询，datagrid设置了分页，可是在查询结果中选择分页 会进入未查询前的对应页面 不是查询后的结果中的该页面 怎么解决
private void DataGrid1_EditCommand(object source,System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
DataGrid1.EditItemIndex=(int)e.Item.ItemIndex;
DataGridDataBind();
}
private void DataGrid1_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{ DataGrid1.CurrentPageIndex=e.NewPageIndex;
DataGridDataBind();
}
private void DataGridDataBind()

{
this.oleDbDataAdapter1.Fill(dataSet1);
recordCount = dataSet1.Tables[0].Rows.Count;
pageCount = (int)Math.Ceiling( recordCount * 1.0 /PageSize);
if(recordCount ==0)
{ this.DataGrid1.CurrentPageIndex = 0;
}
else if(this.DataGrid1.CurrentPageIndex >= pageCount)
{ this.DataGrid1.CurrentPageIndex = pageCount - 1;
}
this.DataGrid1.DataSource =dataSet1;
this.DataGrid1.DataBind();
}
