ChildRowHeight can be set on the main table element of the control like this:

this.radGridView1.TableElement.ChildRowHeight = 750;

When the grid is in a hierarchy and a parent row is expanded, the inner child template will create a new table element and its ChildRowHeight is 205 which is the default value. It would be expected that the height of the inner table element is initially set as the height of the main table element of the control.

A possible workaround is to handle the ChildViewExpanded event of the grid this way:

The writing-mode attribute is ignored when rendering RadSvgImage. 
Here is a sample SVG:

<svg width="200" height="200" viewBox="0 0 200 200" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:svg="http://www.w3.org/2000/svg">
<g>
    <text style="font-size:20px;writing-mode:tb;" x="30" y="30">
        Vertical text
    </text>
    <text style="font-size:20px;writing-mode:vertical-lr;" x="50" y="50">
        Text 2
    </text>
</g>
</svg>

Use attached to reproduce.

- In the excel-like filter popup unselect 0.1, 0.2, and 0.3 and then click "Fork"

- When the layout is loaded the values are changed to 1, 2, and 3. 

Workaround:

Change the culture before saving/loading the layout.

- remove the space from the text in the formatting event so the text is empty

How to reproduce: set the ShowIcon property to false.

this.ShowIcon = false;

• Control Structure Pane - For example, RadForm has a RadTitleBarElement, which contains no styles, because they are inherited from the RadTitleBar control. Here we can add a note, which says from which control the styles are inherited:
  
• Design / Preview Pane - Click on an element from the Design view and select it into the control element tree.
• Elements Pane - Add an option to expand all sub-nodes in the Control Structure tree. Save the setting for the filter chosen by the user.
• Find repository usages: Add an option to expand all sub-nodes.
• Repositories - Sort applied repositories on top or in another list. Currently, we can see all the applied only when we click "Show only applied repositories".
• Repositories - Add an option to filter the repositories by type(font, fill, border, image, and so on). Currently, we can filter them only by name.

Add a RadTextBox on the form and open its smart tag:

Open the editor for the font and select the entire text:

Then, press Del:

When you try to close the editor, an error occurs:

However, the Font is already serialized as null:

As a result, the designer can't be opened any more:
