    paging enhancement needed

    Hello

    I have PagerHelper class created as follows which will show prev, next buttons and in between all page buttons.

    e.g. Prev - 1 - 2 -3 - 4 - 5 - 6 -7 - Next

    But I now need some thing like ... Prev - 1 - 2 -3 - ... - Next

    On clicking "..." it should show next 3 numbers say for e.g.     Prev - 4 - 5 - 6 - ... - Next

    My current code is as follows....

    public class PagerHelper
    {
    @helper GeneratePaging(int currentPage, int totalPages)
    {

    string url = HttpContext.Current.Request.Url.AbsoluteUri;

    string link = "/";

    if (totalPages > 1)
    {
    //<ul class="paging">
    if(currentPage-1 > 0)
    {
    int prev_p = currentPage-1;

    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", prev_p.ToString());
    //<li>
    <a class="pager-btn" href="@link">Prev</a>
    //</li>
    }
    else
    {
    <span class="aspNetDisabled pager-btn">Prev</span>
    }
    for (int p = 1; p < totalPages + 1; p++)
    {
    //string selected = (p == currentPage) ? "selected" : String.Empty;
    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", p.ToString());
    if(p == currentPage)
    {

    //<li>
    <a class="pager-btn current-pager-btn" href="@link" title="Go to page @p of results">@p</a>
    //</li>
    }
    else
    {
    //<li>
    <a class="pager-btn" href="@link" title="Go to page @p of results">@p</a>
    //</li>
    }
    }
    if(currentPage < totalPages)
    {
    int next_p = currentPage+1;

    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", next_p.ToString());

    //<li>
    <a class="pager-btn" href="@link">Next</a>
    //</li>
    }
    else
    {
    <span class="aspNetDisabled pager-btn">Next</span>
    }
    //</ul>
    }
    }
    }

    Also, I have one more file Pager.cs as follows to return nodes.

    public static class Pager
    {
    public static DynamicNodeList Paged(this DynamicNodeList nodes, int page, int pageSize)
    {
    return new DynamicNodeList(nodes.Items.Skip((page - 1) * pageSize).Take(pageSize));
    }

    }

    So, can anyone tell now how to implement the same?

    var skipPage = currentPage + 3;

      for (int p = currentPage; p <= totalPages && p < skipPage; p++)
                                    {
                                            /
    /string selected =(p == currentPage)?"selected":String.Empty;
                                            link
    =GlobalRazorHelpers.AddOrReplaceParam(url,"page", p.ToString());
                                           
    if(p == currentPage)
                                           
    {
                                                   
                                             
    //<li>
                                                   
    <a class="pager-btn current-pager-btn" href="@link" title="Go to page @p of results">@p</a>
                                             /
    /</li>
                                           
    }
                                           
    else
                                           
    {
                                             
    //<li>
                                                   
    <a class="pager-btn" href="@link" title="Go to page @p of results">@p</a>
                                             /
    /</li>
                                           
    }
                                   
    }  

    @if (skipPage <= totalPages)

    {

        <a class="pager-btn" href="@[email protected]" title="">...</a>

        }

    Thank you for the response. It was helpful. But I made few changes and finally following code works fine for me.

    public class PagerHelper
    {
    @helper GeneratePaging(int currentPage, int totalPages)
    {

    string url = HttpContext.Current.Request.Url.AbsoluteUri;

    string link = "/";

    int ButtonsCount = 3;

    if (totalPages > 1)
    {
    int cur_page = currentPage - 1;
    //finding the first linkbutton to be shown in the current display
    int start = cur_page - (cur_page % ButtonsCount);

    //finding the last linkbutton to be shown in the current display
    int end = cur_page + (ButtonsCount - (cur_page % ButtonsCount));

    if (currentPage-1 > 0)
    {
    //specify the position of prev button changed to -1

    int prev_p = currentPage - 1;

    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", prev_p.ToString());

    <a class="pager-btn" href="@link">Prev</a>


    }

    if (start > ButtonsCount - 1)
    {

    int dot = start - 1;
    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", dot.ToString());
    <a class="pager-btn" href="@link">...</a>

    }

    int i = 0, j = 0,page=0;

    for (i = start; i < end; i++)
    {

    if (i < totalPages)
    {
    if (i+1 == currentPage)
    {
    page = i + 1;
    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", page.ToString());
    <a class="pager-btn current-pager-btn" href="@link">@page</a>
    }
    else
    {
    page = i + 1;
    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", page.ToString());
    <a class="pager-btn" href="@link">@page</a>

    }
    }
    j++;
    }

    if (totalPages > end)
    {

    int dot2 = i + 1;
    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", dot2.ToString());

    <a class="pager-btn" href="@link">...</a>

    }

    //condition added to keep the next button till the click of last button
    if (currentPage < totalPages)
    {
    int next_p = currentPage + 1;

    link = GlobalRazorHelpers.AddOrReplaceParam(url, "page", next_p.ToString());

    <a class="pager-btn" href="@link">Next</a>
    }


    }
    }
    }
