Gets or sets a value indicating whether the TreeGrid directive can accept data during drag&drop operation.
A Boolean value. The default is true, stating that TreeGrid accepts rows or other objects to become dropped into its space during HTML5 drag&drop operation.
This property is accessed through 'allow-drop' attribute of TreeGrid directive.
Other objects that are not row objects, can still drop into TreeGrid space as long as the data set in the HTML5 is of 'Text' type. This will automatically create an row object with text set to the value of dropped object text.
Supported in: v1.0.
