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?

Hello,

To process your recent post more efficiently, I created a separate ticket on your behalf: T306639: The 'TabRegion' is removed from regions in the E3339 example when TabbedGroup is unpinned. This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.

This method is terrible. you are creating an IsEdited_ column for every column created and hiding that column. Just to store a Boolean. DevExpress doesn't have a better way of changing the color of a modified cell?

Indeed, this approach implies that you don't have many columns or you wish to highlight cells only for specific fields. Otherwise, I suggest that you choose one of the approaches described in the following links:

Dear support. I have been trying for several days now to export custom cell templates of a pivotgrid but with no luck. From my previous posts, I understand that the exporting of pivotgrid custom cells is not supported, nor are there any plans to support this in the future. This is a serious shortfall for us and could mean that we are just not able to use your controls if we are not able get the data out to the users.

I then came across this post which appears to be doing exactly what we need to do, although this is doing it against a ASPXGridView and not against a ASPXPivotGrid.

I have been trying to "translate" the C# code so that it instead works off of the ASPXPivotGrid but have not been able to.

Is there any chance that somebody there could provide the equivalent sample that will take a ASPXPivotGrid and create a report out of it which includes the templated cells? As an ideal example, if you are able to show how this code would work against your own templated example found here: http://demos.devexpress.com/aspxpivotgriddemos/Templates/CellTemplates.aspx

I have seen several posts now where users are requesting the ability to export templated cells from the pivotgrid, so I am sure any assistance/sample code you can provide along the same lines as what you have done here will be very useful for quite a few of us.

Thanks in advance

Hello,

To export an ASPxPivotGrid control with custom templates use an approach from : http://www.devexpress.com/Support/Center/CodeCentral/ViewExample.aspx?exampleId=E2686 example.

Hi,

this example works fine and it was very good to my application. But i need the same to excel, and when i did the changes i lost the header. Do you have the same example or just the part to export to excel?

Hi,
This example is great. Can we export GridviewBand column also in this approach.  we are using devexpress 2014 v1.2

In ReportHelper.vb, in InitDetailsandPageheader cell.Text is set to the FieldName where I think it should really be set to the ColumnCaption to make use of the work done in GetColumnsInfo which selects the ColumnCaption to be the Caption if there is one or FieldName if there isn't.  It certainly works better for me.  This affects C#,  VB and the MVC example code.
                  
cell.Width = columns(i).ColumnWidth
cell.Text = columns(i).ColumnCaption  'Better to show the Caption than the examples columns(i).FieldName
row.Cells.Add(cell

I was able to replicate this example, to my needs, but unfortunately there is a problem with the tables label headers, because it does not use the one in the grid caption
How can I change this, since its using the class name, not the grid caption
