RadDocking Serialization/SaveLayout not properly working

[Andreas]

Hello there,

I got a problem with saving and loading the current state of my RadDocking generated with a dynamic DataSource.

I bind the list of a data class to the RadDocking or a custom inheritance of it. You can see a few samples in the project assembly.
I have included the Telerik Persistance Framework and the SharpSerializer to save the grid in a data storage (for example: IsolatedStorage)

You can start the project to see what happens, you can change the custom docking elemetn in the MainPage.xaml with the commented one.


------------------------------
In case that you still not get what i mean, the minimum requirements on the product are:
- A list of data (filled with dynamic values) in the ViewModel
- It should save and load the states of the RadDocking if required (e.g.: with 2 dynamic ChartViews and 1 GridView or with 1 GridView and any other Control in RadPanes) and provide it to the ViewModel
- In every RadPane there should be the DataTemplate for the kind of view the customer want (e.g.: A ChartView or a GridView of the data)

The key thing is, that the content of the RadPane depends on the DataTemplate and on the data itself collected in a data class.
A List of Both are bound to the ItemSource Property of the RadDockingExtension which creates a RadPane for every data class and applies the ContentTemplate of it.

If you load the RadDocking it should get back the last state or one of many saved in a DataStorage. The data class should get updated. For testing purposes we will fix the list of the data class to a specific amount of elements (e.g: 3 items) and the same element with new information will always be on the same index, later we could use a Dictionary or something similar.

It is really nessecary to save the state of the RadDocking to a database or a File, the IsolatedStorage is only a example for testing purposes.

There is a simple failure in the ElementSerializationDocking:
        private static void OnByteArrayChange(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            ...
                (d as SharpSerializationDocking).LoadLayout(ms);
            ...
        }

should be:
        private static void OnByteArrayChange(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            ...
                (d as ElementSerializationDocking).LoadLayout(ms);
            ...
        }

Then you get what i mean with your recommended approach for saving and loading states, if its possible, you have to skip the OnByteArrayChange the first time it will be called, i will fix this later.

I will get the other examples also to work as far as i can. because nothing works all the time.

Hi Andreas,

RadDocking provides its own method for saving and loading its layout - SaveLayout and LoadLayout. Into your case the PersistanceFramework can help you to save and load the headers of RadPanes, because they are complex object. I prepared a sample project that demonstrates how to save and load RadDocking's layout and the headers of RadPanes using PersistanceFramework.

Greetings,

Hello,

thank you, I have worked with the sample and it worked as expected! I'm very satisfied with it.

Best regards
