c# winform中自定义的翻页控件，自己设计，供大家参考，具体内容如下
1.主要是使用控件绑定点击事件
用到的控件分别为picturebox lable 上一页pbpage_prev 下一页 pbpage_next 首页 pbpage_begin 尾页pbpage_end 是picturebox控件加背景图
[第 页/ 共 页] 是一个lable [labpageinfo] 在lable上面加了一个隐藏的textbox 控件 [txtpageinfo]
2.将这个翻页的功能单独写在用户控件 ucpageturn 里面 然后在每个页面直接应用就可以了
下面只是把ucpageturn写了出来
还需要在winform页面上应用上

3. 你在资源管文件里面创建的control 文件夹里面，创建了一个用户控件ucpageturn ，那么在工具栏里面会自动显示你刚刚写的ucpageturn组件，把它拖到页面上 ，将这个组件的名字叫做ucpages，这样ucpageturn里面的控件就可以进行编辑
//在initcontrols里面添加textbox输入框的事件
private void initcontrols()
{
ucpages.inputtextbox.keypress += new keypresseventhandler(ucpages_keypress);
ucpages.pagechanged += new pku.cfm.controls.ucpageturn.pagechangedhandle(ucpages_pagechanged);
}
private void ucpages_keypress( object sender, keypresseventargs e)
{
if (13 == e.keychar)
{
int intreturn = sysdefine.nothing;
string strinputtext = ucpages.text.toupper();
if (sysdefine.failed == intreturn)
{
messagebox.show( this .errortext, "信息" , messageboxbuttons.ok, messageboxicon.warning);
}
string pageinputtext = ucpages.inputtext;
int page = 0;
try
{
page = int .parse(pageinputtext);
}
catch
{
page = 1;
}
ucpages.curpageindex = page;
if (sysdefine.failed == refreshlist(page, strinputtext))
{
messagebox.show( this .errortext, "信息" , messageboxbuttons.ok, messageboxicon.warning);
}
}
}
private void ucpages_pagechanged( int oldpage, int newpage, eventargs e)
{
int intreturn = sysdefine.nothing;
string strinputtext = ucpages.text.toupper();
intreturn = refreshlist(newpage, strinputtext);
if (sysdefine.failed == intreturn)
{
messagebox.show( this .errortext, "信息" , messageboxbuttons.ok, messageboxicon.warning);
return ;
}
}
