Freeze integration into custom pages

Overview 
 The DEXPRO Freeze extension provides document archiving functionality that lets users store and retrieve documents, attachments, and related data for any Business Central record. This guide explains how to integrate the Freeze functionality into custom pages. 
 Core components 
 1. Quick Freeze infobox 
 The central component is the "DXP FRZ Quick Freeze FB" page, which provides the following: 
 
 Drag-and-drop file upload functionality 
 Display of archived records related to the current record 
 Quick access to Freeze operations 
 
 2. Management codeunits 
 
 "DXP Extension Mgt." - Manages Freeze queue operations and background processing. 
 "DXP Freeze Search Mgt." - Manages search functionality for archived records. 
 "DXP FRZ Result Mgt." - Manages result display and archive viewing. 
 
 3. Key tables 
 
 "DXP Frz Recent Record" - Stores recent Freeze entries. 
 "DXP Freeze Setup" - Configuration settings. 
 "DXP Freeze Record Type" - Available record types for archiving. 
 
 Implementation steps 
 Step 1: Add the infobox 
 Add the Quick Freeze infobox to the layout area of your page: 
 layout
{
 addfirst(factboxes)
 {
 part("DXP Quick Archive"; "DXP FRZ Quick Freeze FB")
 {
 ApplicationArea = All;
 SubPageLink = "Record System ID" = field(SystemId),
 "Record Table No." = const(Database::"Your Table Name");
 SubPageView = sorting("Entry No.") order(descending);
 }
 }
}
 
 Important notes: 
 
 Replace Database::"Your Table Name" with the appropriate table constant. 
 
 Step 2: Add navigation actions 
 Add Freeze-related actions to the actions area of the page: 
 actions
{
 addfirst(navigation)
 {
 action("DXP Freeze")
 {
 Caption = 'Open Freeze';
 ApplicationArea = All;
 Image = Archive;
 ToolTip = 'Opens the Freeze archive and shows attachments linked to the selected record.';
 ShortcutKey = 'Ctrl+Alt+F';
 trigger OnAction()
 var
 ResultMgt: Codeunit "DXP FRZ Result Mgt.";
 begin
 ResultMgt.SubmitSearchAndShowResults(Rec.RecordId(), FrzSearchMgt.GetSearchCombinationForTable(Rec.SystemId, Rec.RecordId.TableNo()));
 end;
 }
 }
}
 
 Step 3: Add promoted actions 
 actions
{
 addfirst(Category_Category16)
 {
 actionref("DXP Freeze_Promoted"; "DXP Freeze")
 {
 }
 }
 modify(Category_Category16)
 {
 Caption = 'DEXPRO Freeze', Locked = true;
 }
}
 
 Step 4: Add the page trigger 
 trigger OnAfterGetCurrRecord()
begin
 CurrPage."DXP Quick Archive".Page.SetSourceRecord(Rec.RecordId());
end;
 
 Step 5: Declare the variables 
 var
 ExtMgt: Codeunit "DXP Extension Mgt.";
 FrzSearchMgt: Codeunit "DXP Freeze Search Mgt.";
 
 Complete example 
 Here is a complete example for a custom document page: 
 pageextension 50000 "My Custom Doc. Ext." extends "My Custom Document"
{
 layout
 {
 addfirst(factboxes)
 {
 part("DXP Quick Archive"; "DXP FRZ Quick Freeze FB")
 {
 ApplicationArea = All;
 SubPageLink = "Record System ID" = field(SystemId),
 "Record Table No." = const(Database::"Your Table Name");
 SubPageView = sorting("Entry No.") order(descending);
 }
 }
 }

 actions
 {
 addfirst(navigation)
 {
 action("DXP Freeze")
 {
 Caption = 'Open Freeze';
 ApplicationArea = All;
 Image = Archive;
 ToolTip = 'Opens the Freeze archive and shows attachments linked to the selected record.';
 ShortcutKey = 'Ctrl+Alt+F';
 trigger OnAction()
 var
 ResultMgt: Codeunit "DXP FRZ Result Mgt.";
 begin
 ResultMgt.SubmitSearchAndShowResults(Rec.RecordId(), FrzSearchMgt.GetSearchCombinationForTable(Rec.SystemId, Rec.RecordId.TableNo()));
 end;
 }
 }

 addfirst(Category_Category16)
 {
 actionref("DXP Freeze_Promoted"; "DXP Freeze")
 {
 }
 }
 modify(Category_Category16)
 {
 Caption = 'DEXPRO Freeze', Locked = true;
 }
 }

 trigger OnAfterGetCurrRecord()
 begin
 CurrPage."DXP Quick Archive".Page.SetSourceRecord(Rec.RecordId());
 end;

 var
 ExtMgt: Codeunit "DXP Extension Mgt.";
 FrzSearchMgt: Codeunit "DXP Freeze Search Mgt.";
}
 
 Setting up additional search queries 
 To also display archive entries based on records that are not directly linked via the system ID / table number (archived via BC), you can set up additional search queries. This is documented here: https://docs.squeeze.one/books/freeze-for-dynamics-365-bc-de-de/page/zusatzliche-suchabfragen 
 Testing your implementation 
 
 Navigate to your extended page. 
 Verify that the Quick Freeze infobox appears. 
 Test the "Open Freeze" action (Ctrl+Alt+F). 
 Upload test files by drag-and-drop. 
 Verify that archived records appear in the infobox. 
 
 This integration pattern ensures consistent Freeze functionality across all Business Central pages while preserving the user experience established by the DEXPRO Freeze extension.
