为什么我datagrid.currentpage总是0呢
//计算页数,这也是由于datagrid.pagecount总是0出现逼的我写了一个函数///
public   int   pcount(int   count,int   pagesize)
{
int   pcount=0;
  if(count%pagesize==0)
  pcount=count/pagesize;
else
  pcount=count/pagesize+1;
return   pcount;
}
//页面切换
public   void   pagechange(string   pagemark,DataGrid   MyDataGrid,int   count,int   pagesize)
{
int   pcount=this.pcount(count,pagesize);  
switch(pagemark)
{    
case   "first ":
MyDataGrid.CurrentPageIndex=0;
break;
case   "next ":
if(MyDataGrid.CurrentPageIndex <pcount-1) MyDataGrid.CurrentPageIndex+=1; break;
case   "pre ":
if(MyDataGrid.CurrentPageIndex> 0)
MyDataGrid.CurrentPageIndex-=1;
break;
case   "last ":
MyDataGrid.CurrentPageIndex   =   pcount   -   1;
break;
}
}
//page_load中的代码
if(this.Request.QueryString[ "type "]!=null)//其中type既first,next...
{
string   type=this.Request.QueryString[ "type "].ToString();
this.pagechange(type,this.DataGrid2,this.DataGrid2.VirtualItemCount,6);
startIndex   =   this.DataGrid2.CurrentPageIndex   *   this.DataGrid2.PageSize;
this.BindGrid();
}
else
{
this.BindGrid();    
}

viewstate禁用了？
