Strange behavior when resizing with Horizontal splitter items added at runtime

[Luc]

Hi,

I'm using the lastest version of telerik version 2015.2.623.45 with implicit theme.

I'm able to add items to outlookbar at runtime by adding view in the Items collection of OutlookBar. But when the items are added or when i'm playing with the outlookbar horizontal splitter, the control never accept my first resizing and i'm always mandatory to do operation twice to be able to resize correctly the area.

You can found a sample here.

To reproduce :

1- Click many times on the button in the right side. It adds view to the outloobar in the left side.

2- Try to collapse new header with the horizontal splitter. For samples collapse two rows and release the mouse button.

3- The area is automatically resize to original size. 

4- Repeat exactly same operation works.

 

Can you help me ?

Thanks

Regards

Luc

Hi Luc,

Thank you for sharing the sample and for the steps to reproduce the issue. I was able to do so. Looking at the code it seems there is an issue and this is why I will forward this to our developers for further investigation. In the meantime there is a workaround you could use.

Add a single item to the outlookbar at first - in the MainWIndow constructor for instance. Then remove it by attaching to the Loaded event. This would look like the snippet below:

public MainWindow()
{
    InitializeComponent();
    AddItem();
    this.outlookBar.Loaded += outlookBar_Loaded;
}

void outlookBar_Loaded(object sender, RoutedEventArgs e)
{
    this.outlookBar.Items.Clear();
}

This is will prevent the breaking of the outlookbar minimization when using the splitter.

Hope this helps.
