List View Control

  • 12 minutes to read

The List View control allows a user to display items vertically or horizontally and arrange them in groups and columns. Each item can show its caption, subitems, images, check box, and hint. The control supports look & feel settings common to all DevExpress VCL controls. These settings allow you to keep the application’s appearance consistent for all UI elements.

List View Control Example

Manage Items in Standard Mode

If the List View’s OwnerData property is set to False, the control displays information in list items (standard mode).

List Items

Manage Items in Code

The control, its list item collection, and items allow you to add, delete, sort, select, and check items at runtime.

Add Items

The List View includes the following methods that allow you to add items:

  • The control’s AddItem procedure

  • The item collection’s Add and Insert functions

The following code appends a new item with the specified caption to the control:

dxListViewControl1.AddItem('New Item', nil);

Delete Items

You can call the following procedures to delete items:

The following code deletes the first item in the control:

if dxListViewControl1.GetCount > 0 then 

Sort Items

The AlphaSort and CustomSort functions allow you to sort items. These functions raise the OnCompare event you can handle to implement a custom item sorting algorithm.

The following code sorts items by their captions:


Select Items

You can also select items in code.

Item Selection

The List View allows a user to select only one item out-of-the-box. Set the control’s MultiSelect property to True to allow a user to select multiple items. To prohibit a user from selecting an item, set the item’s Enabled property to False. You can handle the control’s OnSelectItem event to perform specific actions when a user selects or deselects an item.

The SelectAll and ClearSelection procedures allow you to select and deselect all items, respectively. To select or deselect a specific item, set its Selected property to True or False.

The following code selects all items in the control:


Check Items

Set the List View’s Checkboxes property to True to display item check boxes.

Checked Items

Use an item’s Checked property to check or uncheck the item. To prohibit a user from changing an item’s check box state, set the item’s Enabled property to False.

The following code checks all items in the control:

  AItem: TdxListItem;
  for AItem in dxListViewControl1.Items do
     AItem.Checked := True;

Manage Items at Design Time

You can create, customize, and delete items in the List View Editor. Double-click the control to invoke the editor.

List View Editor

Use the following buttons in the Items tab to add and delete items:



New Item

Appends a new item in the preview box on the left.

New SubItem

Appends a new subitem to the focused item or focused subitem’s owner.


Subitems specify content displayed in additional columns. Subsequent sections describe how to display list columns.


Removes the focused item and all its subitems or the focused subitem.

Manage Items in Virtual Mode

Set the control’s OwnerData property to True to switch the control to high-performance virtual mode. In this mode, the List View reduces memory use and can handle millions of items. Items are not loaded or changed automatically. Instead, you should manage them in dedicated event handlers as shown below.

Set a non-negative integer to the control’s Items.Count property to specify the target item count. Then, handle the following events to manage and display list items:




Allows you to customize an item when it is about to be displayed.


Allows you to update information about a range of items when they change.


Allows you to search list items.

The form’s OnCreate and the control’s OnData event handlers below specify the item count and assign captions, subitems, and images to each item:

procedure TForm1.FormCreate(Sender: TObject);
  dxListViewControl1.Items.Count := 7;

procedure TForm1.dxListViewControl1Data(Sender: TdxCustomListView;
  AItem: TdxListItem);
  AItems: array[0..6, 0..1] of string = (
    ('ToDoList.txt', 'Text Document'),
    ('readme.txt', 'Text Document'),
    ('scan.pdf', 'PDF Document'),
    ('wallpaper.png', 'PNG File'),
    ('myphoto.png', 'PNG File'),
    ('Documents', 'File Folder'),
    ('Images', 'File Folder')
  AImageIndexes: array [0..6] of Integer = (0, 0, 1, 2, 2, 3, 3);
  AItem.Caption := AItems[AItem.Index][0];
  AItem.ImageIndex := AImageIndexes[AItem.Index];

The following image shows the result:

Virtual Mode

Manage Groups

Assign True to the GroupView property of the control in standard mode to display items in groups.

List Groups

Manage Groups in Code

The control allows you to add, delete, and populate groups at runtime.

Add Groups

You can call the group collection‘s Add and Insert functions to add groups to the control.

The following code appends a new group with the default settings:


Delete Groups

The group collection has the Delete and Clear procedures that allow you to remove groups from the control.

The following code deletes all groups:


Populate Groups

You can assign a group to an item’s Group property to add the item to the group. You can also set an item’s GroupID property to a group identifier to do the same. To remove an item from a group, assign nil (in Delphi) or nullptr (in C++Builder) to the item’s Group property or set the item’s GroupID property to -1.

The following code adds the first item to the first group:

  AItem: TdxListItem;
  AGroup: TdxListGroup;
if (dxListViewControl1.Items.Count > 0) and (dxListViewControl1.Groups.Count > 0) then
    AItem := dxListViewControl1.Items[0];
    AGroup := dxListViewControl1.Groups[0];
    AItem.Group := AGroup;

Manage Groups at Design Time

The List View Editor has the Groups tab that allows you to add and delete groups at design time.

Groups Tab

The New Group button appends a new group to the control. You can click the Delete button to delete all selected groups.

You can select a group and specify its properties in the Object Inspector.

Use the Group combo box in the Items tab to specify which group contains the focused item in the preview box on the left.

Group Combo Box

Manage Columns

The List View control in Report mode shows items in columns. Item display modes are explained in subsequent sections.

List Columns

Manage Columns in Code

The control allows you to add, delete, and resize columns at runtime.

Add Columns

You can call the column collection‘s Add and Insert functions to add columns to the control. The first created column shows item captions, other columns display subitems.

The following code appends a new column with the default settings:


Delete Columns

The column collection has the Delete and Clear procedures that allow you to remove groups from the control.

The following code deletes all columns:


Resize Columns

You can call a column’s ApplyBestFit procedure to adjust the width of a column and display all its content. The control’s ApplyBestFit procedure allows you to adjust the width of all columns.

The following code resizes all columns in the control to display all their content:

dxListViewControl1.ApplyBestFit(nil, False);

You can use a column’s Width property to set the column’s width. Each column has the MinWidth and MaxWidth properties that allow you to specify its width constraints.

Manage Columns at Design Time

The List View Editor has the Columns tab that allows you to add and delete columns at design time.

Columns Tab

The New Column button appends a new column to the control. The Delete button allows you to delete all selected columns.

You can select a column and specify its properties in the Object Inspector.

Customize List View Style

The List View allows you to display items in different modes and customize images, fonts, and paddings for all UI elements.

Switch Item Display Modes

The control’s ViewStyle property specifies the active item display mode. The following table lists the control’s item display modes, corresponding ViewStyle property values, and control appearance settings:

Item Display Mode

ViewStyle Property Value

The Control’s Property





Icon Mode




List Mode




Report Mode




SmallIcon Mode


The ViewStyle property’s type is a scoped enumeration. Use the type name (TdxListViewStyle) together with a scope resolution token (. in Delphi or :: in C++Builder) followed by an enumeration value to refer to this value. For example, use TdxListViewStyle.Icon (in Delphi) or TdxListViewStyle::Icon (in C++Builder) to refer to the Icon value in code.

Show Images

The List View can show images in different UI elements.

Element Images

The control’s ImageOptions property allows you to specify image containers for different UI elements. The following table lists UI element image types and the corresponding properties you can use to specify image containers and image indexes of elements:

UI Element Image Type

Image Container

An Element’s Image Index

Column images


A column’s ImageIndex property

Group images


A group’s TitleImage property

Item main images

ImageOptions.LargeImages (in Icon mode) or ImageOptions.SmallImages (in other modes)

Customize Fonts

The control allows you to use custom fonts for different UI elements.

Element Fonts

The List View shows all UI elements with the default font out-of-the-box (that is, the control uses font settings defined in a parent form or panel). You can use the control’s Fonts property to specify custom fonts for the following UI elements:

Adjust Paddings

The control allows you to use custom fonts for different UI elements. The control’s PaddingOptions property allows you to specify padding settings for the following:
