Does anyone knows how to select a specific viewport by selection filter, I tried with viewport number Dxf code but its selects the first created viewport always.

Entity entvp1 = trans.GetObject(PsrVp1.Value[0].ObjectId, OpenMode.ForWrite)as Entity; Viewport vp1 = entvp1 as Viewport; vp1.Locked = false; Vp1RefNum = vp1.Number; tv1.SetValue(new TypedValue((int)DxfCode.Start, "Viewport"), 0); tv1.SetValue(new TypedValue((int)DxfCode.ViewportNumber, Vp1RefNum), 1); SelectionFilter vp1filter = new SelectionFilter(tv1); PromptSelectionResult psr2vp1 = edt.SelectAll(vp1filter); SelectionSet vp1ss = psr2vp1.Value; Entity entvp1nxt = trans.GetObject(vp1ss[0].ObjectId, OpenMode.ForWrite) as Entity; Viewport vp1nxt = entvp1nxt as Viewport;

Finally, I fixed the issue by adding the CVPORT system variable.

Autodesk.AutoCAD.ApplicationServices.Application.SetSystemVariable("CVPORT", Vp1RefNum);
