How to Use DevExpress 10.2.4 to Create Stunning Dashboards and Reports
DevExpress 10.2.4 is a powerful suite of UI components and tools that can help you create professional-looking dashboards and reports for Windows, Web, and Mobile platforms. Whether you need to visualize data, analyze trends, or monitor performance, DevExpress 10.2.4 has everything you need to get started quickly and easily.
In this article, we will show you how to use DevExpress 10.2.4 to create a dashboard designer and then use it to set up a dashboard with various data visualization elements, such as charts, maps, grids, and gauges. We will also show you how to customize the appearance and behavior of the dashboard items, apply conditional formatting, and bind the dashboard to a data source.
Step 1: Create a Dashboard Designer
A dashboard designer is a control that allows you to design and edit dashboards at runtime. To create a dashboard designer, you need to add the DashboardDesigner control to your project. You can do this by dragging it from the Toolbox onto the design surface of your form or window.
The DashboardDesigner control provides a user-friendly interface that lets you add, arrange, and configure dashboard items using drag-and-drop operations. You can also use the ribbon toolbar to access various commands and options for editing the dashboard layout and content.
Step 2: Add Dashboard Items
A dashboard item is a UI element that displays data in a specific way. DevExpress 10.2.4 supports many types of dashboard items, such as charts, maps, grids, gauges, cards, pies, treemaps, etc. You can add dashboard items to your dashboard by dragging them from the Toolbox onto the design surface of the DashboardDesigner control.
Each dashboard item has its own settings that allow you to customize its appearance and behavior. For example, you can change the type of chart (bar, line, area, etc.), adjust the map zoom level and projection, set the grid column width and sorting order, choose the gauge style and scale range, etc.
Step 3: Bind Dashboard Items to Data
To display data in your dashboard items, you need to bind them to a data source. A data source is an object that provides data for your dashboard. DevExpress 10.2.4 supports various types of data sources, such as databases, Excel files, XML files, Entity Framework models, etc.
To bind a dashboard item to a data source, you need to select the item and then use the Data Source Wizard to specify the data source and the data fields that correspond to the item's dimensions (categories) and measures (values). You can also use expressions to calculate custom dimensions and measures based on existing data fields.
Step 4: Apply Conditional Formatting
Conditional formatting is a feature that allows you to highlight specific values or ranges of values in your dashboard items based on certain conditions. For example, you can use conditional formatting to change the color of bars or cells that exceed a certain threshold, or to display icons or text labels that indicate positive or negative trends.
To apply conditional formatting to a dashboard item, you need to select the item and then use the Conditional Formatting dialog box to define the rules that determine how the values are formatted. You can use predefined conditions (such as greater than, less than, between, etc.) or custom expressions to specify the criteria for formatting.
Step 5: Preview and Save Your Dashboard
Once you have finished designing your dashboard, you can preview it in different modes (designer mode, viewer mode) and platforms (desktop browser mode). You can also export your dashboard to various formats (PDF, Excel, Image) or print it directly from the DashboardDesigner control.
To save your dashboard for future use or distribution, you can use the Save As command from the File menu of the DashboardDesigner control. You can save your dashboard as an XML file (.xml) or as a stream object in code. 061ffe29dd
