Open/Save File Dialog (CTP)
This version introduces a skinnable copy of DevExpress for the standard VCL open/save file dialog. It inherits the dialog from the standard VCL open file dialog, making it as easy to replace the standard dialog as changing the class name.
Enhanced UX
Smooth scrolling
This version adds smooth scrolling support to the following DevExpress VCL components:
- Grid Control
- TreeList Control
- Vertical Grid Control
- Layout Control
- NavBar Control
- PDF Viewer
- Flow Chart Control
- Org Chart Control
- Image Slider Control
- Scroll Box Control
- Image Editor
- Print Preview
Use the newly introduced options in the appearance (or appearance) controller or the appearance settings of the control to activate the desired scroll mode. The dxScrollAnimationTime global constant in the source code allows you to adjust the smoothness of the scroll animation.
Content filling options
In this version, the VCL Grid, TreeList, Pivot Grid and Vertical Grid controls introduce a quick way to fill their in-place editor and/or title, and adjust the spacing between certain UI elements, using the new TdxVisualRefinements .Padding and TdxVisualRefinements.HeaderPadding class attributes to specify the padding on each side of the element.
Delphi
TdxVisualRefinements.Padding := TRect.Create(3, 5, 3, 5);
TdxVisualRefinements.HeaderPadding := TRect.Create(2, 2, 2, 2);
New display style of filter conditions
Now, the filters available in the VCL Grid, TreeList, and Vertical Grid controls support the new visualization style shown in the figure below. This style can help end users easily distinguish color filter items and modify or clear individual filter conditions.
New styles are also provided in the built-in Filter Builder dialog box and the independent Filter Controls.
Grid control
Custom row layout (CTP) in table view and striped table view
The custom row layout allows users to arrange cells in a manner similar to that provided by Layout View, and provides many customization options during design and runtime.
Performance enhancement
- Content rendering speed increased twice
- The layout calculation speed in Banded Table Views can be increased up to three times
- The OnGetFilterValues event handler fills the filter drop-down list with items almost immediately
- Sorting speed of lookup column values increased by 30%
