Update,Remove Fields

Update Field

Aspose.Diagram for .NET lets you update and remove field to Microsoft Visio diagrams from within your own applications, without Microsoft Office Automation.

The Field object represents text field in a text run. The field property, exposed by the Shape class supports a collection of Aspose.Diagram.Field objects.

Programming Sample

The following piece of code update field in shape.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_UpdateField();

// Create a new diagram
// Load source Visio diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get Visio page
Aspose.Diagram.Page page = diagram.Pages.GetPage("Page-1");

//Get Visio Shape
Shape shape = page.Shapes[0];
//Get field
Field fld = shape.Fields[0];
//Update format of field
fld.Format.Val = "";
fld.Format.Ufev.Unit = MeasureConst.Undefined;
fld.Format.Ufev.F = "";

//Update value of field
fld.Value.Val = "1";
fld.Value.Ufev.F = "";
fld.Value.Ufev.Unit = MeasureConst.Undefined;

// Save diagram 
diagram.Save(dataDir + "UpdateField_out.vsdx", SaveFileFormat.VSDX);

Remove Field

The following piece of code remove field in shape.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_RemoveField();

// Create a new diagram
// Load source Visio diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
// Get Visio page
Aspose.Diagram.Page page = diagram.Pages.GetPage("Page-1");

//Get Visio Shape
Shape shape = page.Shapes[0];
//Get field
Field fld = shape.Fields[0];
//Remove field
shape.Fields.Remove(fld);

// Save diagram 
diagram.Save(dataDir + "RemoveField_out.vsdx", SaveFileFormat.VSDX);
