Display No Results in PageBlockTable

Hi,

 

I'm making a pageBlockTable to display a list of custom objects. However, there are times where there won't be any objects to display. Is there any way I can make it show that there are no objects returned in the query, rather than it just being a blank table?

 

I tried this to populate the list with an object that would display 'No records to display', but it returned an error saying : "Error: PartExtension Compile Error: Variable does not exist: Name at line 29 column 52" 

 

(line 29 is the line displayed below)

 

else{
                objectsList.add( new Custom_Object__c (Name = 'No records to display'));
            }

 

What other options do I have?

Hello,

Just want to extend the Starz26 idea.

 

if suppose in Controller you have list name contactList,

then you can check directly if the size of the list is 0 or not.

<apex:pageBlockTable value="{!innerContactList}" var="innerCont" rendered="{!(contactList.size != 0)}">

 hope it helps :)

You can use the rendered attribute to hide the pageblock table if no records are returned and create a message that displays in its place using the rendered attribute if no records are returned....

I've done a little bit of rerender work, but I'm not sure how to do this exactly. How can I rerender if the controlling list has a size of 0?

 

Sorry, I'm pretty new to Visualforce & web design.

In the Controller or extension

 

         Public Integer objSize {get;set;}

 

When you do the SOQL to return the data and assign to a list or whatever, add

 

         objSize = LISTVARIABLE.size(); **This should be what your Pageblock table uses as the Value

 

Then in your pageblock table add

 

        rendered="{!IF(objSize>0,TRUE,FALSE)}"

why not just use innerContactList.size?

 

I normally do something like this:

 

 

<apex:pageBlockTable value="{!innerContactList}" var="innerCont" rendered="{!(innerContactList.size != 0)}">
   (pageBlockTable stuff)
</apex:pageBlockTable>
<apex:outputText rendered="{!(innerContactList.size = 0)}" value="There are no contacts to display." />
