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); |
