Deleting layer and all shapes that belong to it

Hi,

Is there a way to delete a layer and all shapes belonging to that layer? At the moment when deleting the layer, it will move the shapes over to another layer.

Thanks.

Hi,

Thank you for contacting support. You can delete a layer along with its member shapes by using the layer index as below:

[.NET, C#]

string lyrIndex = “1”;
// Load a Visio drawing

Diagram diagram = new Diagram(@“C:\Diagram\test2069\Drawing1.vsdx”);
// Get Visio page
Aspose.Diagram.Page page = diagram.Pages.GetPage(“Page-1”);
List<long> list = new List<long>();

// get a list of member shapes
foreach (Aspose.Diagram.Shape shape in page.Shapes)
{
LayerMem layer = shape.LayerMem;
bool isMember = layer.LayerMember.Value.Contains(lyrIndex);
if (isMember)
list.Add(shape.ID);
}

// remove member shapes
for (int i = 0; i < list.Count; i++)
{
Aspose.Diagram.Shape shape = page.Shapes.GetShape(list[i]);
page.Shapes.Remove(shape);
}

// remove layer
page.PageSheet.Layers.Remove(page.PageSheet.Layers[Int32.Parse(lyrIndex)]);

// save Visio drawing
diagram.Save(@“C:\Diagram\test2069\Output.vsdx”, SaveFileFormat.VSDX);

Hi Imran,

Thanks for the help. That seemed to do the trick.
