Introducing High Contrast Theme in WinForms Theme Studio

With the Essential Studio 2019 Volume 2 release, Syncfusion has included a Microsoft Windows 10-like high contrast black theme for WinForms controls. With the help of our Theme Studio application, users can change the primary control colors based on their needs. Then, export the required theme as a theme library, and include it in their application to apply the same appearance to other WinForms controls. To know more about the Theme Studio application and how it works, refer to this blog post or the online documentation.

In addition to the high contrast theme, we have also made the following updates in our Theme Studio:

• Theme support is extended to these controls: Spreadsheet, Pivot Grid, Menu, ToolBar, Popup, DomainUpDownExt, NumericUpdown, FontComboBox, Gradient Panel, GradientPanelExt, Gradient Label, and Rating Control.
• We have replaced most of the images(*.bmp, *.png, and so on) with icon fonts in the controls for better clarity and efficient usage when it comes to DPI and new theme inclusion. To learn more about this, refer to this blog.

Generating high contrast theme

In Theme Studio, you can apply the high contrast theme using the Choose Theme option. This will apply dark colors to the showcase controls. The users can change the color codes of the following brushes if they wish.

Theme Studio with High Contrast Black Theme

Once after applying colors to the controls, export the theme in library format(*.dll). To do so, click the Export button in the bottom of the left pane. In the export dialog that appears, all the controls are showcased based on their category. Click Select All to select all the listed controls, or choose individual controls as desired. The size of the output assembly is proportional to the number and size of the selected controls.

IMPORTANT NOTE: The name used when saving the theme in library format (*.dll) should be used for applying the theme to the controls in a WinForms user application. In this example, we have named the theme library “HighContrastBlackTheme.dll”.

Applying high contrast theme to Syncfusion WinForms controls

To apply the high contrast theme to Syncfusion Windows Forms controls:

1. Add the reference of the exported theme library in the application.
2. Load the assembly using the SkinManager.
3. Set the ThemeName property of the controls to the name given to the theme library.

Theme Library Added into User Application

The following code demonstrates the high contrast black theme set to the DataGrid control.

//Load theme assembly into application using SkinManager
SkinManager.LoadAssembly(typeof(HighContrastBlackTheme).Assembly);

SfDataGrid sfDataGrid = new SfDataGrid();
//Other code blocks to bind a data source and define columns for DataGrid
//Apply high contrast theme to SfDataGrid
sfDataGrid.ThemeName = "HighContrastBlackTheme";
this.Controls.Add(sfDataGrid);

Now, run the application and experience the control’s rich user interface.
