为winform应用程序开发寻呼机c＃ [英] Developing pager for winform application c#
问题描述
$
我首先搜索谷歌获取任何现成的数字寻呼机样本以获取胜利形式但不幸的是我没有找到。许多存在用于Web应用程序。所以我决定发展自己的。我有一个用户控件，我想在运行时在用户控件
上添加一些标签来模拟数字寻呼机链接。
喜欢<< ; < 1 2 3 4 5> >>

这里是我的代码到目前为止

}
}

public bool HasNextPage
{

{
return（CurrentPage + 1< = RecordsPerPage）;
}
}
int pagecount = 0;
public int PageCount
{
得到
{
pagecount = TotalRecords> 0？ （int）Math.Ceiling（TotalRecords /（double）RecordsPerPage）：0;
;&NBSP;&NBSP; return pagecount;
}
}
public void BuildPager（int CurrentPage）

否则为

}
}
}
我的第一个上一个，下一个& prev按钮将被修复。我不会在运行时生成这些按钮。我想在用户控制的运行时只生成像1 2 3 4 5等数字链接。
有一件事我需要修复那个寻呼机条的数量是在我的情况下固定，即5.我想显示总是5个寻呼机链接，如1 2 3 4 5或6 7 8 9 10等。
假设总数记录是36，我希望每页显示10条记录，因此我需要在运行时生成4个寻呼机链接。如果记录数为110则应该正确处理所有内容，我认为正确的逻辑不会以这种方式生成寻呼机链接。
如果总记录为110且每页记录为10，则总页面栏应为11但我想一次只显示5个。第一次1 2 3 4 5当用户点击第5个寻呼机栏并且下次点击下一个按钮然后寻呼机链接将是6 7 8 9 10.这样
i想要显示寻呼机链接但是正确的逻辑不会来介意生成我想显示寻呼机链接的方式。如果有人帮我总是处理5个寻呼机链接的生成，那将会很有帮助。

i search google first to get any ready made sample for numeric pager for win form but unfortunately i found none. many exist for web application. so i have decided to develop my own. i have take one user control and i want to add some label on the user control
at run time for simulating numeric pager link.
like << < 1 2 3 4 5 > >>
here is my code so far
public partial class PagerBar : UserControl
{
public PagerBar()
{
InitializeComponent();
}
int totalrecords = 0;
public int TotalRecords
{
get { return totalrecords; }
set { totalrecords = value; }
}
int recordsperpage = 0;
public int RecordsPerPage
{
get { return recordsperpage; }
set { recordsperpage = value; }
}
int curpage = 0;
public int CurrentPage
{
get { return curpage; }
set { curpage = value; }
}
int maxpagerlink = 0;
public int MaxPagerLink
{
get { return maxpagerlink; }
set { maxpagerlink = value; }
}
public bool HasPreviousPage
{
get
{
return (CurrentPage > 1);
}
}
/// <summary>
/// Gets the boolean value of next page
/// </summary>
public bool HasNextPage
{
get
{
return (CurrentPage + 1 <= RecordsPerPage);
}
}
int pagecount = 0;
public int PageCount
{
get
{
pagecount = TotalRecords > 0 ? (int)Math.Ceiling(TotalRecords / (double)RecordsPerPage) : 0;
return pagecount;
}
}
public void BuildPager(int CurrentPage)
{
if (CurrentPage >= MaxPagerLink)
{
}
else
{
}
}
}
my first prev,next & prev button will be fixed. i will not generate these button at run time. i want to generate only numeric link like 1 2 3 4 5 etc at run time on user control.
one thing i need to fix that number of pager bar is will be fixed in my case and that is 5. i want to show always 5 pager link like 1 2 3 4 5 or 6 7 8 9 10 etc.
suppose total records is 36 and i want to show 10 records per page so 4 pager link i need to generate at run time. the right logic is not coming to my mind to generate pager link in such a way if number of records is 110 then everything should be handle properly.
if total records is 110 and records per page is 10 then total pager bar should be 11 but i want to show only 5 at a time. first time 1 2 3 4 5 when user click on 5th pager bar and next time click on next button then pager link will be 6 7 8 9 10. this way
i want to show pager link but right logic is not coming to mind to generate the way i want to display pager link. it will be great help if some one help me to handle generation of 5 pager link always.

===================
Drag the pager control on to the form and set some properties like below one
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
bbaPager1.RecordCount = 53;
bbaPager1.MaximumNumberofLinks = 5;
bbaPager1.PageClicked += new PagerControl.BBAPager.PageClick(bbaPager1_PageClicked);
}
void bbaPager1_PageClicked(object sender, PagerControl.PageClickEventHandler e)
{
MessageBox.Show("Page " + e.SelectedPage.ToString());
}
}
