Disabling Checkbox Inside PageBlockTable

Hi All
I had come across in a requirement,the Requirement  was to select one record and disable all the records after selecting in that table. I have done it by using JavaScript, I think it will help you.
This is the page.
<apex:page>
     <apex:form>
            <script>
                   function checkboxuse(tag) {
                        var menus  = document.getElementsByClassName("Teststyle");
                        if (tag.checked == true) {
                             for (var i = menus.length - 1; i >= 0; i--)
                             {
                                    menus[i].disabled = true;
                             }
                            tag.disabled = false;
                        }
                       else {
                             for (var i = menus.length - 1; i >= 0; i--)
                             {
                                     menus[i].disabled = false;
                             }
                         }
                     }     
              </script>
             <apex:PageBlock>
                      <apex:pageBlockTable value = "{!listofRecords}" var = "c" >
                                <apex:column header = "Select" >
                                        <apex:inputCheckBox value = "{!c.selected}" id="tst" styleClass="Teststyle"                             onchange="return checkboxuse(this)"/>
                                </apex:column>
                               <apex:column header = "FieldName"> 
                                         <apex:inputFiled value = "{!c.filedAPIName}" /> 
                              </apex:column>
                     </apex:pageBlockTable>  
             </apex:PageBlock>
         </apex:form>
  </apex:page>

You have to use wrapper class, listofRecords should be a wrapper class List.

Hi,
Good post. I have a requirement where i have to check a checkbox based on condition.
E.g I have 3 objects contact,application and verifier. Verifier is junction object b/w contact and application. In vf page i have a pagebocktable with 2 columns. 1st column has all contacts and 2 column is for verifier and has checkboxes. If a contact is verifier then checkbox should be checked.

Generally we can display list of records of one Object in a pageblock table.For example suppose there are two objects Account and Contact. We can not display list of Accounts records as well as list of Contacts record in one pageblock table.


listofRecords should list of records of one object.

I saw that link,but there only contact name is displayed in one page block table.other one is check box. It is easy we can display.
