Hi Friends,

I need help in fixing the VF Pages. 
I created a Class and VF Pages where I want to display a Table values. so, I created a Pageblocktable. Now I have 1 issue when I table has values and other table does not have a values it is diplaying both table which looks awkward.
I need to hide the columns if there is no values.

Below is my VF code and Image for your reference. 
<apex:panelGrid columns="3" width="90%">
            <apex:pageblock >
                <apex:pageBlockTable value="{!orderItemsList1}" width="100%" var="div">
                    <apex:column >
                        <apex:pageBlockTable width="100%" columns="1" border="1" cellspacing="0" cellPadding="1" value="{!div.OrderItems}" var="custom">
                            <apex:column headerValue="Body" >
                                <apex:outputField value="{!custom.Product2.Name}"/><p class="onepointfive"/>
                                Blue Plates Required:<apex:outputField value="{!custom.Product2.Blue_plates__c}"/><p class="onepointfive"/>

Hi,

Use conditional statement to hide/show the pageBlockTable as mentioned below.
<apex:outputpanel rendered = "{!IF(v.orderItemsList1.size >0)}">
<apex:pageBlock>
<apex:pageBlockTable value="{!orderItemsList1}" width="100%" var="div">
</apex:outputPanel>

Hope it helps, if it does mark it as solved.

Thanks

Error got rectified but still I could see the empty pageblock table which does not have values.

Thanks

So you are seeing Body and Fridge even when you applied it. Can you check if you are getting orderItemsList1.size() != 0?

Thanks

Hi Meghna,

Still am seeing Body and Fridge after checking !=0.

Could you please let me know if I need anything to change in class apart from VF.

Thanks.

Hi HTANIRS,
Please try the below code and let me know if this works for you. If still need modifications do let me know.

VFPage: 
<apex:page controller="Demo">
    <apex:pageBlock >
        {!con.size }
        <apex:outputPanel rendered="{! IF(con.size > 0, true, false)}">
        <apex:pageBlockTable value="{!con}" var="cn"  >
            <apex:column value="{!cn.Name}"></apex:column>
        </apex:pageBlockTable>
            </apex:outputPanel>
    </apex:pageBlock>
</apex:page>

Controller: 
public Demo {
    public List<Contact> con{get;set;}
    public Demo(){
        con = [SELECT Name FROM Contact where Id=: ''];
    }
}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
Thanks,
Ajay Dubedi
