Hello Everyone,

              <apex:facet name="header">
              <apex:inputCheckbox onclick="selectAllCheckboxes(this,'inputId')"/>
              </apex:facet>
              <apex:inputCheckbox value="{!cont.Oppflagvalue}" id="inputId" immediate="true" >

          public Boolean Oppflagvalue{get; set;}
           public  boolean submitInitial{get; set;}
          public wrapperContact (contact cnt) {
              this.cnt = cnt;
              if(cnt.Id != ApexPages.currentPage().getParameters().get('id'))
              {
                   Oppflagvalue= false;
                   if(Oppflagvalue==false)
                   {
                   submitInitial=true;
                   }
                   
               }
                        else
                        {

So basically you want to disable next if none of the checkboxes are selected, there are few ways you can achieve it, 

1. Via Javascript, 
2. or via controller method, 

Via controller, 
You can add a flag isButtonEnabled which you can set to true and re-render the commandButton, something like 

 

public boolean isButtonEnabled {get;set;}

public void checkButton() {
     
    isButtonEnabled = false; // Set to false and check wrapper list if any flag is true

    // Check the wrapper class to see if any checkboxes are checked
     for (WrapperContact wc : contactWrapperList ) {
         if (wc.Oppflagvalue) {
           isButtonEnabled = true;
           break;
         }
     }

}
 

In the visualforce page, the actionSupport will call this method and rerender the button
 

<apex:inputCheckbox value="{!cont.Oppflagvalue}" id="inputId" immediate="true" >
     <apex:actionSupport event="onclick" action="{!checkButton}"reRender="buttonId"/>
 </apex:inputCheckbox>

....
...
<apex:commandButton id="buttonId" value="Next>>>" action="{!submitInitial}" rendered="{!initialStep}" rerender="fid" disabled="{!NOT(isButtonEnabled)}"/>
 

Hope this helps.

You can use the disabled attribute on inputcheckbox, something like this
  
<apex:inputCheckbox value="{!cont.Oppflagvalue}" id="inputId" immediate="true" disabled="{!NOT(cnt.Oppflagvalue)}"/>
