    Viewport Layer Freeze Display Issue

    All,

    The following code freezes LayerId in all viewports in all layouts except for LayoutToSkip. This all works well except for the fact that the layers do not correctly display, ie they all remain visible in all viewports. When I check the viewport layer settings they are all correct. If the drawing is saved, closed, and re-opened, then the layers correctly display. As you can see, I have tried vp.UpdateDisplay() and ed.UpdateTiledViewportsFromDatabase() which have no effect. Manually trying regen or regenall does not correct the display. Any thoughts? Thanks, Dale

    <code>

    // this works, but the display is not correct until dwg is re-opened

    publicstatic void LayerFreezeAllViewports(ObjectId pLayerId, string pstrLayoutToSkip)

    {

    Document doc = AcadApp.DocumentManager.MdiActiveDocument; 

    Editored = doc.Editor; 

    Databasedb = doc.Database; 

    using(Transaction tr = db.TransactionManager.StartTransaction())

    {

    ObjectId[] ids = new ObjectId[1] { pLayerId }; 

    DBDictionary layoutDict = tr.GetObject(db.LayoutDictionaryId, OpenMode.ForRead) as DBDictionary; 

    // get current layout

    string lstrCurrentLayout = LayoutManager.Current.CurrentLayout; 

    foreach(DBDictionaryEntry entry inlayoutDict)

    {

    if(entry.Key.ToUpper() != "MODEL")

    {

    Layout lay = tr.GetObject(entry.Value, OpenMode.ForWrite) asLayout; 

    // new layouts must be initialised - done at create

    //if(lay.LayoutName.ToUpper() != lstrCurrentLayout.ToUpper())

    //setCurrentLayoutTab(lay.LayoutName);

    // check for layout matching param to leave layers on

    if(lay.LayoutName.ToUpper() != pstrLayoutToSkip)

    {

    foreach(ObjectId vpId inlay.GetViewports())

    {

    Viewport vp = tr.GetObject(vpId, OpenMode.ForWrite) asViewport;

    vp.FreezeLayersInViewport(ids.GetEnumerator());

    // DESPERATE TRY

    vp.UpdateDisplay();

    // ??? save/close/open and all is correct

    }}}}

    tr.Commit();

    }

    // ed.UpdateTiledViewportsFromDatabase();

    }

    Hi,

     

    IMHO, this is not due to your code but to the current value of LAYOUTREGENCTRL while switching between tabs after you run your code.

    Thanks, I'll try that.

    Regards, Dale
