How do I create "Page X of Y" like List Views?
I'm stuck trying to actually set the set controller page number - my best try simply refreshes the page, leaving the page unchanged.
VF Snippet:
Page <apex:inputText value="{!pageNum}"> <apex:actionSupport event="onchange" action="{!setPageNum}"/> </apex:inputText> of "{!totalPages}"
Controller snippet:
public Integer pageNum{ get{ return setCon.getPageNumber(); }//get set; }//pageNum public Integer totalPages{ get{ Integer numPages =setCon.getResultSize()/setcon.getPageSize(); if(numPages*setcon.getPageSize()!=setCon.getResultSize()){ numPages++; }//if return numPages; }//get set; }//total pages public void next() { setCon.next(); }//next public void previous() { setCon.previous(); }//previous public void setPageNum(){ setCon.setPageNumber(pageNum); }//setPageNum
Perhaps pageNum does the "get" method when setPageNumber() tries to get the changed value and resets it to the "unchanged" value?
Thx for the help!
//Try the following to get the page number
public String pageParam {
get {
if (pageParam == null) {
pageParam = paramByParamId(PARAM_PAGE, '1');
}
return pageParam;
}
set;
}
//Try the following to get the total number of pages
Integer totalNumPages = Math.round(Math.ceil(controller.getResultSie() / ( 1.0 * controller.getPageSize())));
Let me know if you face any difficulty
Hope this helps you..........
Thanks for the response sravu! I wasn't able to figure out what you meant below though.
What should "paramByParamId" do? This isn't a standard VF, Apex, or HTML method.
My primary issue is trying to set the page of the controller by using an input box, which I haven't been able to figure out yet.
Thanks for the help!
it will give you the current page number
