Public Property AllowSplitters As Boolean?

Property Value

Type	Default	Description
Nullable<Boolean>	`true`, for Dock UI; `false`, for Layout UI	true, to allow users to resize the LayoutGroup’s child items; false, to restrict users from resizing the LayoutGroup’s child items; null, to allow users to resize the LayoutGroup’s child items only when Customization Mode is enabled.

Remarks

If a LayoutGroup’s AllowSplitters property is true, users can resize the LayoutGroup’s child items with the mouse:

When the AllowSplitters property is null, users can resize a LayoutGroup’s children in the following cases:

• The LayoutGroup combines dock items.
• The LayoutGroup combines layout items and Customization Mode is enabled.

You can use the LayoutGroup.IsSplittersEnabled property to get whether users can resize the LayoutGroup’s child items.
