starting in version 12.1 I get an exception, in version 11.2 the sample did work
(I based my application on this)

  InnerException:

Hello, we have an issue with your sample E3339 (related to the use of regions and adapters). The sample is successfully working with the 11.2.11 version in one of our testing computers. But we’re now integrating the last version of DevExpress (12.1.4) in our sandbox computer and it doesn’t work: the project is compiling but it doesn’t work (the adapters aren’t working: the flow execution isn’t entering in the adapters, in the function Adapt). We’re experiencing the same problem than K.Wessing: System.ArgumentException was unhandled by user code
  Message=This RegionManager does not contain a Region with the name 'LeftRegion'.
We have been checking your technical support and it seems there was another issue between the 11.1.x and the 11.2.x, and your teams adapted the sample project for the new DevExpress version. Is it possible that it’s happening the same?
Thanks,
       Juan Lopez

I am using the LayoutGroupAdapter
I would like to be able to switch from one view to an other within the same LayoutGroup region.
I 've added the Remove action:
 if (e.Action == NotifyCollectionChangedAction.Remove)
            {
regionTarget.Items.Clear();
}
Scenario:
in region : <dxd:LayoutGroup cal:RegionManager.RegionName="{x:Static Infrastructure:RegionNames.DetailsRegion}" />
#1 Add a viewA - OK
#2 Remove viewA - OK
#3 Add viewB - OK
#4 Remove viewB - OK
#5 add viewA - Getting ERROR below
Please advice.
Thank you

The Remove event is not handled in the documentgroup adapter which does not reclaim the memory when tab is closed.

Hide the leftregion, the navbar be removed, and hide leftregin again, throw error.

Why this example is so bugged?
After detaching a panel - disappears a content, please try detach Toolbox...
And why this example craches every time, when attach-detach event happening...

Please, supply Working example.

private void OnItemsCollectionChanged(IRegion region, LayoutGroup regionTarget, object sender, NotifyCollectionChangedEventArgs e)
        {
            if (lockItemsChanged)
            {
                return;
            }
            if (e.Action == NotifyCollectionChangedAction.Remove)
            {
                lockViewsChanged = true;
                var lp = (LayoutPanel)e.OldItems[0];
                var view = lp.Content;
                //lp.Content = null;
                region.Remove(view);
                lockViewsChanged = false;
            }
        }

Cause of removing content is "lp.Content = null;" row...
Why was existing this row in example?

Can you complete the code for remove action. We have something as below to remove any tabs that are floating or in the default layout group. it does not find tabs in newly created layout groups.

  case NotifyCollectionChangedAction.Remove:
                    List<DocumentPanel> panelToRemove = new List<DocumentPanel>();
                    List<FloatGroup> floatGroupToRemove = new List<FloatGroup>();
                    DockLayoutManager managerRemove = regionTarget.GetDockLayoutManager();
                    foreach (DocumentPanel panel in regionTarget.Items)
                    {
                        foreach (IPanelInfo oldItem in e.OldItems)
                        {
                            if (panel.Caption.Equals(oldItem.Title))
                            {
                                panelToRemove.Add(panel);
                            }
                        }
                    }

                    foreach (DocumentPanel pnl in panelToRemove)
                    {
                        regionTarget.Items.Remove(pnl);
                    }

                    panelToRemove.Clear();

                    foreach (var floatGroup in managerRemove.FloatGroups)
                    {
                        foreach (DocumentPanel panel in floatGroup.Items)
                        {
                            foreach (IPanelInfo oldItem in e.OldItems)
                            {
                                if (panel.Caption.Equals(oldItem.Title))
                                {
                                    panelToRemove.Add(panel);
                                }
                            }
                        }

                        foreach (DocumentPanel pnl in panelToRemove)
                        {
                            floatGroup.Items.Remove(pnl);
                        }

                        if (floatGroup.Items.Count == 0 )
                        {
                            floatGroupToRemove.Add(floatGroup);
                        }
                    }

                    foreach (FloatGroup floatGroup in floatGroupToRemove)
                    {
                        managerRemove.FloatGroups.Remove(floatGroup);
                    }

                    break;

Unfortunately this example doesn't support selection/activation of the views. A call to IRegion.Activate(view) will have no effect.

There is an error when the Region (TabbedGroup) is unpinned and you try to open a new view in that region.

The situation is that when de TabbedGroup is unpinned also it's removed from the regions in the region manager, so the error is: This RegionManager does not contain a Region with the name 'TabRegion'.

The DockLayoutManager creates an AutoHideGroup and moves all the items from the TabbedGroup unpinned to this new AutoHideGroup but doesn't maintain the relation with the Region.

I'm using the v14.2 version. How is possible to manage this behavior?

I'm having issues with this approach. I have a DirType Entity that has many DirParam Entities each. If I bind to grid as mentioned below, I get the desired drilling but in the child view, If I enter a value for any cell and move to another cell, the value disappears. This is not happening on main view but sub views only.

Just take care of the .net type specified in xml ResourceId, that match the type of property corresponding the Id in your object.

Hello,

The Type property in an XML string that represents Ids of resources associated with an appointment should match the type of the data field mapped to Resource.Id.  In this example, a CustomResource business object has the ResID property of the System.Int32 type. So, the Type property should be set to System.Int32.

While researching this subject, I noticed that the data field  mapped to the AppointmentMappingInfo.ResourceId property is of the System.Object type. It is recommended to use a data field of the string type to store XML text with information on assigned resources. So, I will update the example accordingly.

Should you have additional questions in this regard, let me know. I will be happy to assist you.

This example is not working! Could you please fix it.

Hello Daniel,
Thank you for your attention. We will fix it soon.
However, you can do this right now on your side. Please open the Project properties, navigate to the Application tab and change Target Framework to 4.0. Then, navigate to the Build tab and change Platform Target to x86.

Question Comments

I have a XAF application and require the same of what is asked here (https://www.devexpress.com/Support/Center/Question/Details/T216541) by Yasir 9 months ago, to create a timesheet with a UX friendly interface like this one here (https://www.devexpress.com/Support/Center/Attachment/GetAttachmentFile/badaed21-c3f3-11e4-80ba-00155d624807). Even if I would choose to go down this (from a XAF perspective) hackery route of implementing what I want in this application, how would I even seamlessly integrate that under a clickable navigation item in my XAF application? I have tried to approach my problem from several perspectives with my multi-platform knowledge and I have a very hard time coming a acceptable solution. My timesheet reporting tool also has several association to different tables for its projects and users and a bunch of other stuff and this solution would basically make the application error-prone when somebody makes a change to this part of the program, not knowing that he has to modify all kinds of SQL-code in a ASPx page somewhere else. I am even volunteering for the job to write a nice XAF extension for this, but also this seems like it would be a living nightmare to do in comparison to other platforms, like nodejs, for instance, or even PHP or what have you.

As I said. I am willing to volunteer for the task, but then I obviously will need youur help on how to write a nice controller for this that would support both web and win modules.

I hope to hear from somebody.

Best,
B

Question Comments

GridControl grid = sender as GridControl;
grid always null ???

Thanx Dear fro reply me i'll do it

1. Can you copy instead from the original grid rather than deleting the row being dragged? In other words, after dragging a particular row, let the original grid still have the row, as opposed to the row disappearing.
2. Can you modify the code such that the row being dragged can be captured and displayed, modified before it is dropped?

David,

Just change the DragDrop handler to not import and delete the source and instead create a copy of the DataRow and import that into the second grid.
