TdxSaveFileDialog Class
A Save As dialog component.
Declaration
TdxSaveFileDialog = class(
TSaveDialog,
IdxSkinSupport
)Remarks
The TdxSaveFileDialog class implements a non-visual component that displays a Save As dialog that allows users to select and save files in the file system. The TdxSaveFileDialog component is compatible with the standard TSaveDialog component but has additional APIs for file preview customization as well as look & feel settings common to all DevExpress VCL controls. These settings allow you to apply the same skin to all UI elements and maintain appearance consistency for all application components, including shell dialogs.
The Save As dialog can display a preview of the selected file at the right border. You can use the OptionsPreview property to customize preview settings.
Invoke the Save As Dialog
You can call the component’s Execute procedure to invoke the Save As dialog. This dialog allows a user to select and save files. When a user clicks the Save button, the dialog saves the path to the selected file name to the FileName property and closes.

Skinnable Shell Dialogs in DevExpress Components
All DevExpress components with built-in Windows shell navigation functionality (such as Spreadsheet and Rich Edit controls) use skinnable dialogs instead of standard system dialogs. You can change the dxUseStandardShellDialogs global constant value to True if you prefer standard system dialogs.
Create a Custom Save As File Dialog
Inherit a class from TdxfrmSaveFileDialog to create a custom Save As dialog form. Assign a reference to the created class to the SaveFileDialogFormClass global variable to replace the built-in Save As dialog form with a custom implementation.
