You can simply use custom pagination here and bind your wrapper class list to add the pagination functionality
this is pagination class which you should implement from your controller
public abstract class paginator1 {
public Integer FirstPage {get; set;} // first row number in the list.
public Integer PageSize {get; set;} // number of rows per page. //previously currentPageCount
public Integer LastPage {get; set;} // row index of the first record the in the last page
public Integer TotalRows; // total rows in all pages.
public Integer page{get; set;}
//navigates to previous page
public void previousPage()
{
if(FirstPage - PageSize >= 0)
{
FirstPage -= PageSize ;
page--;
}
}
//navigates to last page
public void lastPage()
{
FirstPage = calcLastPage();
}
//calculates page number of last page
private Integer calcLastPage()
{
if(TotalRows >= PageSize )
{
page=Math.mod(TotalRows, PageSize) == 0 ? TotalRows/PageSize : TotalRows/PageSize + 1;
return ((page-1)*5);
}
else
{
return 0;
}
}
//navigates to next page
public void nextPage()
{
if(TotalRows== 0 || PageSize == 0) return;
if(FirstPage + PageSize < TotalRows)
{
FirstPage += PageSize ;
page++;
}
}
//navigates to first page
public void firstPage()
{
page=1;
FirstPage = 0;
}
}
===============================
This is page code to add this on page and bind your wrapper class, please modify and add your wrapper class
