Diagramming for Java, V4.0.4

Posted on by

MindFusion has released Diagramming for Java 4.0.4 Here is an overview of the new features:

Import of Visio 2013 files

You can use the new VisioImproter class to import *.vsdx files, created by Visio 2013. In order to use it, you must import the com.mindfusion.diagramming.importers namespace. The Import method has several overloads, which let you choose whether to import the diagram as a single Diagram whose content is merged from all imported pages or as a DiagramDocument whose pages correspond to the Visio pages. At this time VisioImporter supports the basic flowchart and data flow Visio stencils.

Import of OpenOffice Draw files

The new DrawImporter class can import .odg files, created by the OpenOffice Draw vector graphics editor. In order to use it, you must import the com.mindfusion.diagramming.importers namespace. DrawImporter supports shapes from the General and Flowchart shape palettes in Draw. You can choose among several overloads of the Import method to import the OpenOffice drawing into a DiagramDocument whose pages correspond to the Draw pages, or into a single Diagram whose content is merged from all imported pages.

Miscellaneous

  • The AutoSnapToNode property allows links to be snapped to nodes from a distance
  • Use the new RoundedLinks and RoundedLinksRadius properties to draw arcs at the joints of Cascading and Polyline links’ segments.
  • Several new shapes for better compatibility with Visio 2013 basic stencil were added: RightTriangle, Decagon, Trapezoid, Star4Pointed, Star5Pointed, Star6Pointed, Star7Pointed, Star16Pointed, Star24Pointed, Star32Pointed, Donut, Plaque.

WinForms Spreadsheet Databinding

Posted on by

In this blog we will discuss how to display the information from a database inside MindFusion.Spreadsheet for WinForms, how to validate and edit the data and how to write back any changes.

Introduction

We start off by creating a new Windows Forms Application in Visual Studio, adding a WorkbookView control to the main form and adding the Northwind database (nwind.mdb) as a data source. For simplicity we only add the Categories table. After compiling the application we can add the DataSource and the CategoriesTableAdapter as components to the main form.

Loading the data

We traverse the rows in the data source and populate the spreadsheet by assigning the data to the Data property of the respective worksheet cells. To prevent certain columns from being edited (for example auto-increment keys and image fields), we mark these columns by setting their Tag property. All columns and rows beyond those that actually display data are hidden by setting their IsHidden property to true. The column titles are set to the names of the corresponding database columns. Finally, the columns are resized to fit their contents through the ResizeColumnsToFit method of the view. The complete code of the data loading can be found in the LoadData method.

Note, that during the data loading, the loading flag is set to true. This is done to prevent some unnecessary operations in the CellChanging and CellChanged event handlers.

Setting up the view

To resemble a data grid, we need to disable certain functions in the view. More specifically, we need to hide the tabs, the formula bar, the auto-fill handle and the hidden header indicator.

workbookView1.ShowHiddenHeaderIndicators = false;
workbookView1.AllowAutoFill = false;
workbookView1.ShowTabs = false;
workbookView1.ShowFormulaBar = false;

Performing validation

We want to prevent the users from changing the values of certain cells – for example, the cells in the auto-increment column and the cells representing pictures. To do this, we will handle the InplaceEditStarting event of the WorkbookView and the WorksheetCellChanging event of the Workbook. In the event handlers we check the Tag value of the related column. If the column is marked as read-only, we set the Cancel property of the event argument to true, to prevent the edit or change.

Adding new rows

When we populated the data from the dataset, we left an empty row at the bottom of the spreadsheet. The intent is that this empty row should be used to add new rows to the table. When the user edits a cell of the empty row, the row key is automatically calculated and a new empty row is added at the bottom of the spreadsheet. To implement this functionality, we handle the WorksheetCellChanged event of the Workbook. In the event handler, we inspect the row of the edited cell. If this is the last visible row in the spreadsheet, we calculate a key for this row and reveal another row at the bottom of the spreadsheet by setting its IsHidden property to false.

Saving changes to the database

Changes are immediately reflected back to the database from within the WorksheetCellChanged event handler. New rows are added via the Rows.Add method of the Categories data table. Existing rows are updated directly through the respective DataRow object. The changes are effectively performed by calling the Update method of the table adapter.

The following image shows the running sample:
