Hi all,

I'm trying to write a related list button on a master record that opens a table that you can edit certain fields of the masters child records.

My visual force page works but gets ALL child records in the system not just those relating to the master record I am on.

My Apex coding is:

public class EditAllButtonForTimeSheetController
{
    //This will store the Id from the URL i.e., the Id of the Record that belongs to the Master Object
    public String TSRecordId        {get; set;}
    public List<Time_Sheet_Items__c> TSiRecords  {get; set;}
    public Time_Sheet__c TSRecord                 {get; set;}
    //Constructor. This would build everything for our VF Page.
    public EditAllButtonForTimeSheetController()
    {
        TSRecordId = ApexPages.CurrentPage().getparameters().get('id');

        //Make sure we have the Id in the URL
        if(!String.isBlank(TSRecordId)){

            //Fetch the Time Sheet Record Details
            TSRecord =
            [SELECT ID,Name,Time_Sheet_Week_Ending__c FROM Time_Sheet__c WHERE Id = :TSRecordId ];

            //Fetch all the Time_Sheet_Items Records with respect to the Time_sheet Record. 
        //Note: Child_To_Parent_Lookup__c  is Lookup/M-D field on my Child SObject to the Parent – Master
            TSiRecords =
                [SELECT Id,Time_Sheet__c,D_Type__c,D_Product_manager__c,D_Project__c,
        Day_Monday__c,Day_Tuesday__c,Day_Wednesday__c,Day_Thursday__c,Day_Friday__c,Day_Weekend__c
                FROM TIme_Sheet_Items__c WHERE Time_sheet_ID__c = :TSRecordId ];
                
        }
    }
}


VF PAGE

<apex:page standardController="Time_Sheet_Items__c"
              Extensions="EditAllButtonForTimeSheetController">
  <apex:form >
    <apex:pageBlock >
      <apex:pageMessages />
      <apex:pageBlockButtons >
        <apex:commandButton value="Save"
                            action="{!save}"/>
      </apex:pageBlockButtons>
      <apex:pageBlockTable value="{!Time_Sheet_Items__c}"
                           var="TSi">
        <apex:column style="width:5%" value="{!TSi.D_Project__c}"/>
        <apex:column style="width:5%" value="{!TSi.D_Type__c}"/>

    <apex:column style="width:5%" headerValue="Monday">
          <apex:inputField value="{!TSi.Day_Monday__c}"/>
        </apex:column>
    <apex:column style="width:5%" headerValue="Tuesday">
          <apex:inputField value="{!TSi.Day_Tuesday__c}"/>
        </apex:column>
    <apex:column style="width:5%" headerValue="Wednesday">
          <apex:inputField value="{!TSi.Day_Wednesday__c}"/>
        </apex:column>
    <apex:column style="width:5%" headerValue="Thursday">
          <apex:inputField value="{!TSi.Day_Thursday__c}"/>
        </apex:column>
    <apex:column style="width:5%" headerValue="Friday">
          <apex:inputField value="{!TSi.Day_Friday__c}"/>
        </apex:column>
    <apex:column style="width:5%" headerValue="Weekend">
          <apex:inputField value="{!TSi.Day_Weekend__c}"/>
        </apex:column>
      </apex:pageBlockTable>     
    </apex:pageBlock>
  </apex:form>
</apex:page>

Any help would be great.
