Creating a background for GroupElement

TorbjørnDalløkken2 — Mon, 05 Jun 2023 08:28:03 GMT

Hi.

I'm working on an add-in which creates several layout-elements, including a groupelement which contains some text and a scalebar. I'm able to add background / outline for each of the elements in the group, but not on the group itself. How do I do this? I can't see any methods or properties on the GroupElement-object, nor the CIM-definition.

Here's how I've created the GroupElement.

ElementInfo info = new ElementInfo(); info.CornerRounding = 25; GroupElement groupElement = ElementFactory.Instance.CreateGroupElement( elementContainer: Module1.layout, elements: elementList, elementName: "JSRMålestokkGruppe", groupElementInfo: info );

Can anyone help me with this and point me in the right direction?

You might have already done this, but there is a utility called CIM Viewer that you can download from GitHub and builder: GitHub - Esri/arcgis-pro-sdk-cim-viewer

using the CIM Viewer you can then examine the CIMGroupElement in order to come up with a programmatic approach:

Using the objects that i discovered using the CIMViewer i build the following code snippet that gets the CIM Group's graphic frame and changes the width and the color of the group's frame (name MyGroup).

internal class ChangeGroupElement : Button { private static CIMColor Red = new CIMRGBColor { R = 255, G = 0, B = 0, Alpha = 100// 0 for transparent and 100 for opaque }; private static CIMColor Black = new CIMRGBColor { R = 0, G = 0, B = 0, Alpha = 100// 0 for transparent and 100 for opaque }; protected override async void OnClick() { // Find 'MyGroup' and make changes var layout = LayoutView.Active?.Layout; if (layout == null) { MessageBox.Show("No active layout view"); return; } var grp = layout.FindElement("MyGroup"); if (grp == null) { MessageBox.Show("MyGroup not found"); return; } try { await QueuedTask.Run(() => { var cimGrp = grp.GetDefinition() as CIMGroupElement; if (cimGrp != null) { // check the graphic frame (see CIMViewer) if (cimGrp.GraphicFrame != null) { // get the border symbol in the graphic frame var borderSym = cimGrp.GraphicFrame.BorderSymbol as CIMSymbolReference; if (borderSym != null && borderSym.Symbol != null) { // the border symbol is comprised of SymbolLayers // ... change the first SymbolLayer which is a CIMSolidStroke var symbol = borderSym.Symbol as CIMLineSymbol; if (symbol.SymbolLayers != null) { var solidStroke = symbol.SymbolLayers.OfType<CIMSolidStroke>().FirstOrDefault(); if (solidStroke != null) { var width = solidStroke.Width + 1; solidStroke.Color = width % 2 == 0 ? Red : Black; solidStroke.Width = width; } } } } grp.SetDefinition(cimGrp); } }); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } }
