WinForm DataGridView分頁功能

winform 裡面的datagridview不像webform裡面的gridview那樣有自帶的分頁功能，需要自己寫**來實現分頁，效果如下圖：

.cs:

;        
private
string strconn = @"

";         
private
string strprocedure = "

//////

void binddatawithpage(int
index)
//////

try                
catch
(sqlexception err)
finally}}
private
void allenpage1_pageindexchanged(object
sender, eventargs e)}}
