This article provides an example of how asp.net implements simple paging.Share it for your reference.
The implementation is as follows:
/// <summary>
/// Paging Content
/// </summary>
/// <param name="size"> Page Size </param>
/// <param name="count"> Number of pages </param>
/// <param name="currendIndex"> Current Page </param>
/// <param name="pattern">url Pattern: demo.aspx?page={0}</param>
/// <param name="target"> Window Mode </param>
/// <returns></returns>
public static string get_pagenation(int size,
int count,
int currendIndex,
string pattern,
string target)
{
//1> Open Window Target
target = string.IsNullOrEmpty(target) ? "_top" : target;
//2> PageCount
int pageCount = count / size;
pageCount = pageCount * size == count ? pageCount : pageCount + 1;
//3> Paging Content
StringBuilder strHtml = new StringBuilder();
strHtml.Append("<span class='pagenation'>");
#region First Processing
if (currendIndex > 1)
{
strHtml.AppendFormat("<a href='1' target='{0}'>[ home page ]</a>", target);
strHtml.AppendFormat("<a href='{0}' target='{1}'>[ upper 1 page ]</a>", string.Format(pattern, currendIndex - 1), target);
}
else
{
strHtml.Append("<span class='disabled'>[ home page ]</span> <span class='disabled'>[ upper 1 page ]</span>");
}
#endregion
#region Middle part
int i = 1;
int right = (currendIndex + 4) > pageCount ? pageCount : currendIndex + 4;
if (currendIndex > 6)
{
i = currendIndex - 5;
}
else
{
right = pageCount >= 10 ? 10 : pageCount;
}
for (; i <= right; i++)
{
if (i == currendIndex)
{
strHtml.AppendFormat("<font class='current'>{0}</font>", i);
strHtml.AppendLine();
continue;
}
strHtml.AppendFormat("<a href='{0}' target='{1}'>[{2}]</a>", string.Format(pattern, i), target, i);
strHtml.AppendLine();
}
#endregion
#region Tail handling
if (currendIndex == pageCount)
{
strHtml.Append("<span class='disabled'>[ lower 1 page ]</span><span class='disabled'>[ Last ]</span>");
strHtml.AppendFormat(" In total ({0}) page ", pageCount);
}
else
{
strHtml.AppendFormat("<a href='{0}' target='{1}'>[ lower 1 page ]</a>", string.Format(pattern, currendIndex + 1), target);
strHtml.AppendFormat("<a href='{0}' target='{1}'>[ Last ]</a>", string.Format(pattern, pageCount), target);
strHtml.AppendFormat(" <label> In total ({0}) page </label>", pageCount);
}
#endregion
strHtml.Append("</span>");
return strHtml.ToString();
}I hope that the description in this paper will be helpful to everyone's asp.net program design.
