TcxEditRepositoryCheckGroupItem Class
A repository item that stores check group settings.
Declaration
TcxEditRepositoryCheckGroupItem = class(
TcxEditRepositoryItem
)
Remarks
A check group displays a set of check boxes that correspond to individual options.
The TcxEditRepositoryCheckGroupItem
class overrides the Properties property that allows you to access and customize check group settings.
Edit Repository Items and Standalone Editors
Edit repository items are useful when you need to share the same settings between multiple editors of the same type. To accomplish this goal, you can assign the same edit repository item to RepositoryItem properties of all target editors.
Edit Repository Items and Container Controls
A container control item (such as a toolbar edit item or a column (or any other data item) in a Data Grid, Vertical Grid, or Tree List control) can embed an in-place editor shipped with the ExpressEditors Library. An in-place editor exists (and, therefore, has its own WinAPI handle) only when the target container control item is being edited. Otherwise, the container control item displays a static editor image for resource usage optimization.
Create a Check Group Repository Item at Design Time
To create a check group repository item at design time, double-click a TcxEditRepository component to invoke its collection editor.
The collection editor allows you to manage repository items. Click the Add… button to invoke a repository item creation dialog.
Select the CheckGroup item and click the Ok button to create a check group repository item.
Create a Check Group Repository Item in Code
The following code example creates a check group repository item, defines a list of check boxes, and assigns the created repository item to two existing unbound check groups:
uses cxEdit, cxExtEditRepositoryItems;
// ...
var
ACheckGroupRepositoryItem: TcxEditRepositoryCheckGroupItem;
ARepositoryItem: TcxEditRepositoryItem;
ACheckGroupItem: TcxCheckGroupItem;
begin
ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryCheckGroupItem);
ACheckGroupRepositoryItem := ARepositoryItem as TcxEditRepositoryCheckGroupItem;
// Populates the created repository item with check group items
ACheckGroupItem := ACheckGroupRepositoryItem.Properties.Items.Add;
ACheckGroupItem.Caption := 'Circle';
ACheckGroupItem := ACheckGroupRepositoryItem.Properties.Items.Add;
ACheckGroupItem.Caption := 'Rectangle';
ACheckGroupItem := ACheckGroupRepositoryItem.Properties.Items.Add;
ACheckGroupItem.Caption := 'Ellipse';
ACheckGroupItem := ACheckGroupRepositoryItem.Properties.Items.Add;
ACheckGroupItem.Caption := 'Triangle';
ACheckGroupItem := ACheckGroupRepositoryItem.Properties.Items.Add;
ACheckGroupItem.Caption := 'Square';
// Assigns the created repository item to two existing unbound check groups
cxCheckGroup1.RepositoryItem := ACheckGroupRepositoryItem;
cxCheckGroup2.RepositoryItem := ACheckGroupRepositoryItem;
end;
Check Group Repository Item Deletion
To delete all check group repository items in a TcxEditRepository component, call its RemoveItems procedure and pass a reference to the TcxEditRepositoryCheckGroupItem
class as a parameter.
If you need to delete an individual check group repository item, release it directly in code (call the Free procedure in Delphi or use the delete
keyword in C++Builder).
