Columns Headers of a PageBlockTable not displaying

Hi 

 

Facet not working on my table and I can not find how to make the first column  looks as a saleforce row header...

Thanks for your help

 

 

<apex:pageBlock >


<apex:pageBlockSection collapsible="true" title="table 1" columns="1">
<apex:PageBlockTable columns="{!colLabels.size+1}"
rows="{!rowLabels.size+1}" value="{!LBItems}" var="it">

<apex:column >
<apex:outputlabel value="{!it.rowlabel}" / >
</apex:column>

<apex:repeat value="{!it.rowBoxIt}" var="rbi">
<apex:column >
<apex:facet name="header" >{!rbi.colLabel}
</apex:facet>
<apex:outputlabel value="{!rbi.name}" / >
</apex:column>

</apex:repeat>

</apex:PageBlockTable>
</apex:pageBlockSection>

This sample code might help you:

 

<!-- Shows a two column table of contacts associated with the account.  
The account column headers are controlled by the facets.-->

<apex:page standardController="Account">
    <apex:pageBlock title="Contacts">
        <apex:dataTable value="{!account.Contacts}" var="contact" cellPadding="4" border="1">
            <apex:column >
                <apex:facet name="header">Name</apex:facet>
                        {!contact.Name}
            </apex:column>
            <apex:column >
                <apex:facet name="header">Phone</apex:facet>
                        {!contact.Phone}
            </apex:column>
        </apex:dataTable>
    </apex:pageBlock>
</apex:page>

Hi,

 

The default header value displays only when you use <apex:inputfield/> or <apex:outputfield/> in your columns. If you want to display the header value user headerValue attribute in <apex:column/>. If you are using <apex:facet/>, headerValue will not work.

Hi,

 I tried both but the headers wont display.

 

Also <apex:outputlabel value="{!it.rowlabel}" / >

it.rowlabel  is a header as well but no idea how to get the salesforce header format.

 

Thanks for your answers.

 

 

 

Using Facet

 

<apex:column >
<apex:outputlabel value="{!it.rowlabel}" / > 
</apex:column> 

 


<apex:repeat value="{!it.rowBoxIt}" var="rbi"> 
<apex:column > 

    <apex:facet name="header">"{!rbi.colLabel}"</apex:facet>
    apex:outputlabel value="{!rbi.colLabel}" / >


   <apex:inputcheckbox }" > 

  </apex:inputCheckbox>

</apex:column> 
</apex:repeat>

 

 

using headerValue

 

<apex:column >
<apex:outputlabel value="{!it.rowlabel}" / > 
</apex:column> 

 


<apex:repeat value="{!it.rowBoxIt}" var="rbi"> 

    <apex:column headervalue="{!rbi.colLabel}" >
    apex:outputlabel value="{!rbi.colLabel}" / >


   <apex:inputcheckbox }" > 

  </apex:inputCheckbox>

</apex:column> 
</apex:repeat>

Another thy as I just can not find a way to display the titles of my dynamic table.

Thanks for your help

 

That works well   (coltitle displays well)

apex:repeat value="{!colLabels}" var="colTitle">
<apex:column >

<apex:facet name="header" > {!colTitle}
</apex:facet>
...
</apex:column>
</apex:repeat>

 

this doesn't work (Titles not displayed)

 

<apex:repeat value="{!it.rowBoxIt}" var="rbi">

<apex:column >
<apex:facet name="header" >{!rbi.colLabel }</apex:facet>


</apex:column>
</apex:repeat>

R using standardcontroller or customcontroller?

 

<apex:repeat value="{!it.rowBoxIt}" var="rbi">

<apex:column >
<apex:facet name="header" >{!rbi.colLabel }</apex:facet>


</apex:column>
</apex:repeat>

apex:column has a parameter called Header value, which can be used to provide header information.

Even we faced this issue. In the end we decided to use dynamic visualforce component creating it from apex class in order to populate the correct header value.
  Evenever we were using apex:column tags within apex:repeat tag, we were facing this issue. below is sample code:
  VF page:
  <apex:pageblockSection columns="1" title="Pageblocktable using dynamic visualforce components from Apex">
            <apex:dynamicComponent componentValue="{!MyPageBlockTable}"  invokeAfterAction="true"/>
        </apex:pageblockSection>
 
  Apex Class
  public List<oppwrapper> opplist{get;set;}
  public class oppwrapper{
                public opportunity opp{get;set;}
                public List<CompetitorWrapper> complist{get;set;}
                public oppwrapper(){
                        complist=new List<CompetitorWrapper>();
                }
        }
        public class competitorWrapper{
                public Competitor__c comp{get;set;}
        }
        //populate the opplist with values in apex and then use below method to create dynamic pageblocktable...
        public Component.Apex.PageBlockTable getMyPageBlockTable(){
   Component.Apex.PageBlockTable  table=new Component.Apex.PageBlockTable(var='op');
   table.expressions.value='{!opplist}';
   if(opplist.size()>0){
                    Component.Apex.pageblocksection pgblksec1 = new Component.Apex.pageblocksection ();
                    pgblksec1.columns=1;
                    Component.Apex.inputField inputField1 = new Component.Apex.inputField ();
                    inputField1 .expressions.value = '{!op.opp.stagename}';
                    pgblksec1.childComponents.add(inputField1);
                    Component.Apex.inputField inputField2 = new Component.Apex.inputField ();
                    inputField2.expressions.value = '{!op.opp.nextstep}';
                    pgblksec1.childComponents.add(inputField2);
                    Component.Apex.Column column = new Component.Apex.Column(headerValue=opplist[0].opp.name);
                    column.childComponents.add(pgblksec1);
                    table.childComponents.add(column);
                    if(opplist[0].complist.size()>0){
                        integer count=0;
                        for(competitorWrapper comp:opplist[0].complist){
                            Component.Apex.pageblocksection pgblksec2 = new Component.Apex.pageblocksection ();
                            pgblksec2.columns=1;
                            Component.Apex.inputField inputField3 = new Component.Apex.inputField ();
                            inputField3.expressions.value = '{!op.complist['+count+'].comp.Stage__c}';
                            pgblksec2.childComponents.add(inputField3 );
                           
                            Component.Apex.inputField inputField4 = new Component.Apex.inputField ();
                            inputField4.expressions.value = '{!op.complist['+count+'].comp.nextStep__c}';
                            pgblksec2.childComponents.add(inputField4 );
                           
                            Component.Apex.Column column1 = new Component.Apex.Column(headerValue=opplist[0].complist[count].comp.name);
                            column1.childComponents.add(pgblksec2);
                            table.childComponents.add(column1);
                          
                          
                        }
                    }              
        }
        return table;
    }

The problem is caused by repeat. Same thing happend to me. I change the value in header to be a value in a list and it works
 <apex:repeat value="{! displayColumList}" var="col">                                
                                <apex:column headerValue="{!col}" rendered="{! col=='Action'}" >
                                    <apex:inputCheckbox value="{!l.IsSelected}">
                                        <apex:actionSupport event="onchange" rerender="totalSelected" />
                                    </apex:inputCheckbox>
                                </apex:column>
