I have created two visibilities VisibilityState0 and VisibilityState1 for a blockreference, now if i want to change the visibility of that block using c# code, how can i do it if I have a blockreference object?

Hi,

You can use this method:

public static void SetDynamicPropertyValue(BlockReference block, string propName, object value) { if (block.IsDynamicBlock) { var props = block.DynamicBlockReferencePropertyCollection; foreach (DynamicBlockReferenceProperty prop in props) { if (prop.PropertyName.Equals(propName)) { try { prop.Value = value; } catch (System.Exception ex) { var ed = Application.DocumentManager.MdiActiveDocument.Editor; ed.WriteMessage($"\n{ex.Message}"); } break; } } } }

My blockreference is not dynamic, then what to do?

Visibility states only work with dynamic blocks. Other than attributes, non-dynamic blocks cannot have insertions that have a differing appearance.
