The Data Repeater is a Form Control that shows the data in a tabular format directly from the user-defined Data Structure. Data Repeater can be configured to give users full control over the data, allowing them to create new rows, modify existing ones, and delete rows as required. This flexibility ensures efficient data management and customization within the Data Structure, enhancing the overall user experience and data manipulation capabilities.

The following video demonstrates the core functionality of Data Repeater, where the user adds a new Row to add an Item.

Data Repeater Use-Case in an Inventory Management System

In an inventory management system, the Data Repeater control can be used to handle product inventory data, providing users with comprehensive control over their inventory.

View Inventory Data: The Data Repeater will display a list of products in the inventory, with each row representing a specific product's details, such as name, SKU, quantity, and price. Users can quickly scroll through the list to view and analyze the available inventory.

Update Product Information: Users can edit and update product details by selecting a row within the Data Repeater. They can modify fields like quantity, price, or product description, ensuring real-time synchronization with the underlying data structure.

Add New Products: The Data Repeater allows users to add new product entries on the fly. Users can click an "Add Product" button or similar control, which generates a blank row within the Data Repeater. They can input the necessary information for the new product, such as name, SKU, and price.

Delete Products: Users can remove product entries directly from the Data Repeater. Selecting a row and utilizing a "Delete" button or similar functionality removes the corresponding product's information from the data structure, ensuring accurate inventory management.

Data Repeater Settings

The following table describes all the settings available in the Properties Panel for the Data Repeater Form Control.

Data Repeater Setting Name		Description
Selection Type		Modifies the visual indicator that separates a selected line item from the unselected. It is highly recommended to use a Selection Type for easier reading of the Data Repeater by the end-user, especially if the Designer anticipates large data. None: No visual indicator separates the selected line item. Visual Indicator: A bar to the left of the Repeater appears next to each item, and its color changes to the assigned color when selected. Line Number: Each line number added is successively enumerated. Highlight Row: The selected row gets highlighted with the assigned color.
Is Read Only		Displays the data within the Repeater as an uneditable list.
Auto Add New Row		When enabled, it opens a new field to specify a Form component. Once the end-user hits the Tab key on the specified component, a new line item is added in the end.
	Insert Row on FocusOut From	Specifies which component spawns new rows if the user enters the Tab key.
Show Separator		Enabled by default, this setting automatically generates a line break between line items when adding a new line item. Disabling this removes these line breaks.
Override Required Message		Allows the Designer to customize the error text displayed when an end-user attempts to submit missing required data in the component.
Short Key Set-Up		Promotes smoother navigation and accessibility of the Repeater by assigning hotkeys for movement between line items. Up and Down arrow keys are usually assigned for their respective movements.
Add Button		If the ‘Data Repeater Add Button’ control is used in the Form. This will allow you to pick the button for this specific Data Repeater.
Remove Button		If the ‘Data Repeater Remove Button’ control is used in the Form. This will allow you to pick the button for this specific Data Repeater.

Form Controls Used in Conjunction with Data Repeaters

Data Repeaters can be configured to let end users add or remove a data row. This can be done using the following Form controls in conjunction with the Data Repeater.

Control Name	Description
Data Repeater Add Button	This is a Form control button which, when clicked by the end users, will add a new row to the Data Repeater. This Form control will not add a new row in between of two rows, this will only add at the bottom of the data view.
Data Repeater Remove Button	This is a Form Control Button which, when clicked by the end users, will remove any of the selected rows from the Data Repeater.
Remove Data Repeater Row	This control is availbale in v8.18 and above This is an alternative option to the ‘Data Repeater Remove Button’. The only difference is this Form Control works independently of the row selection. This is a button type control that gets added with each row of the data repeater where users can click on this button to remove that respective row from the data repeater. This control is not located in the toolbox of the Form which host the Data Repeater, but it is located in the toolbox of the source of the Data Repeater. Click on the Edit Source → Toolbox → User Controls → Remove Data Repeater Row.
