Diagramming for JavaScript with jQuery

Posted on by

Diagramming for JavaScript can use jQuery for browser abstraction instead of Microsoft Ajax. If you want to try the new feature, please download this archive containing a pre-release mindfusion.diagramming.js build and a sample page:

https://mindfusion.dev/_beta/jsdiag_jquery.zip

To enable jQuery support, set MindFusionImpl=”JQuery” before loading the diagram script:

Code:

MindFusionImpl = "JQuery";

Instead of MSAjax $create function, use the static Diagram.create(element) method to create a Diagram instance for given Canvas element:

Code:

diagram = MindFusion.Diagramming.Diagram.create($("#diagram")[0]);

MindFusion.Spreadsheet: Formatted Text

Posted on by

Starting with version 1.2, MindFusion.Spreadsheet adds support for formatted text. The control can import, create, display and export formatted texts. In this blog we will demonstrate how to create formatted text in a cell.

Introduction

As with all previous blogs we start off by creating a new Windows Forms Application in Visual Studio and adding a WorkbookView control to the main form. The WorkbookView displays a Workbook with a single worksheet.

Creating the formatted text

Formatted texts are created programmatically by instantiating from the FormattedText class. The class provides a constructor, which can initialize the formatted text from a markup string, similar to HTML. The string supports the following tags: <fontname=”fontname“>, <fontsize=”fontsize“>, <i>, <b>, <u>, <s>, and <color=”#rrggbb“>. The following code creates several formatted texts:

worksheet.Cells["A1"].Data = new FormattedText("The meeting is <color=\"#ff0000\">important</color=\"#ff0000\">!");
worksheet.Cells["A2"].Data = new FormattedText("<fontsize=\"18\">A title <fontsize=\"8\">(1994)");
worksheet.Cells["A3"].Data = new FormattedText("This text contains some keywords that are highlighted.");</fontsize=\"8\"></fontsize=\"18\">

Exporting

The formatted texts are exported to all supported formats, including HTML, PDF, XLSX, ODS, image, and so on. The following image illustrated the formatted texts created earlier exported to HTML:

Diagramming for ASP.NET, V5.2 and Diagramming for ASP.NET MVC, V2.1

Posted on by

MindFusion has released a new version of NetDiagram and of MvcDiagram. Both components boast two new layouts:

Tree map layout
Tree maps represent hierarchies by nesting child nodes within their parents, where the areas of leaf nodes are proportional to their Weight values. Unlike other layout algorithms, TreeMapLayout expects hierarchies to be defined via grouping or containment (see AttachTo method and ContainerNode class), and will ignore any links in the diagram. The diagram area covered by the topmost nodes in a hierarchy is specified via the LayoutArea property. By default, the layout tries to keep the ratio of node sides as close as possible to one.

The tree map layout.

Decision flowchart layout
DecisionLayout arranges simple flowcharts consisting of decision boxes with up to three outgoing links per node and activity boxes with a single outgoing link per node. The nodes are arranged in columns and rows, whose distance depends on the HorizontalPadding and VerticalPadding property values. When links share the same row or column, they are placed at a distance specified via LinkPadding. The layout arranges nodes recursively starting from StartNode.

Miscellaneous

  • Layout algorithms now automatically resize diagram’s Bounds if it’s not large enough to fit the arranged content. To revert to old behavior and keep fixed Bounds size, set GrowToFit to false.
  • A few bugs have been cleared – read details for NetDiagram here and for MvcDiagram here.

The control includes many samples, detailed documentation and step-by-step tutorials. Every features is duly documented and there’s plenty of code to copy. The component is not only powerful and scalable, but easy to learn and fun to use.

About Diagramming for ASP.NET MVC Control: It is a multi-purpose diagramming tool that consists of two parts: a .NET class library running on the server and a client side control implemented in JavaScript. The server side .NET library implements a flow-diagramming object model that lets you define structures such as trees, flowcharts and graphs. Every element in the diagram is easily accessible and the whole diagram is rendered as part of an HTML page by just calling the DiagramView extension method.

On the client the diagram is rendered by a DiagramView JavaScript control that draws its content on an HTML Canvas. The user is able to add nodes and links simply by drawing them with the mouse. There is also a NodeListView control, which lets users create new nodes via drag and drop. MvcDiagram also supports various automatic layout algorithms that will make every diagram easy to understand and nice to look at. The diagram can also be easily serialized in binary or XML format.

Exporting is done in a variety of formats including Pdf, Svg, Visio and more. You can read details about the components at the MvcDiagram features page.

Diagramming for ASP.NET, V5.1

Posted on by

The new version of Diagramming for ASP.NET programming component has just been released. Here is an overview of the most important new features:

Canvas mode improvements

  • undo / redo support: call diagram.setUndoEnabled(true) on client side to start tracking changes.
    Call undo() or redo() methods to restore diagram state. Actions cannot be undone after postback;
  • animations: the Animation JavaScript class can be used to animate values of various properties of
    nodes and links. An example is available at http://mindfusion.dev/_samples/animations/Animations.html
  • clipboard support: call the copyToClipboard, cutToClipboard and pasteFromClipboard methods to copy or paste selected items;
  • the swimlane grid is now rendered in Canvas mode;
  • the magnifier tool is now supported in Canvas mode;
  • as well other new properties and events – check them here.
A typical flowchart built interactively. Some of the nodes support animation. See the sample here.

Intellisense support
The package now includes a MindFusion.Diagramming-vsdoc.js file providing code completion information. To load it in Visual Studio, add e /// tag to the top of your script files. Use the static Diagram.create and Diagram.find methods instead of $create and $find to let Visual Studio infer the type of returned Diagram objects correctly.

Node list control
The NodeListView control is a listbox control that can host any type of objects that derive from DiagramNode. Users can drag objects from the NodeListView onto the Diagram canvas. The control creates a copy of the selected node at the position of the mouse pointer.

Resize of multiple nodes
The new AllowMultipleResize property lets users resize multipleselected nodes simultaneously. When enabled, dragging the corner or side adjustment handle of any node resizes all nodes in the selection.

Export of Visio 2013 files
You can export the content of Diagram and DiagramDocument objects to Visio 2013 VSDX files. First, you should add a reference to the MindFusion.Diagramming.Export.Visio.dll assembly. Currently, the exporter supports shapes from the Visio basic stencil. Support for more shapes will be added upon request.

Improvements in the Visio2013Importer

  • The importer now supports Visio group shapes. Child shapes in groups are no longer lost when importing, and their corresponding diagram nodes are attached to the corresponding group node.
  • Visio NURBS curves are now imported as Bezier-style links.
  • and more – check them here.

Headers and footers in PDF
The PdfExporter can now add headers and footers to the exported pages. Their contents and font are customizable.
