TreeNodeStyle::NodeSpacing Property

Gets or sets the amount of vertical spacing between the node to which the TreeNodeStyle object is applied and its adjacent nodes.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
property Unit NodeSpacing {
	Unit get ();
	void set (Unit value);
}

Property Value

Type: System.Web.UI.WebControls::Unit
The amount of vertical space, in pixels, between the node to which the TreeNodeStyle is applied and its adjacent nodes at the same level. The default is 0 pixels.

ExceptionCondition
ArgumentOutOfRangeException

The selected value is of type Percentage or is less than 0.

Use the NodeSpacing property to control the amount of vertical spacing between a node that the TreeNodeStyle is applied to and its adjacent nodes at the same level. This space is inserted between the upper edge of the current node and the lower edge of the previous node, as well as between the lower edge of the current node and upper edge of the next node. The upper space is not rendered for the first node in the TreeView control, because this would leave an unnecessary gap at the top of the control.

The NodeSpacing and ChildNodesPadding properties are applied independently. Whether or not the node is expanded does not affect the node spacing.

The value of this property is stored in view state.

The following code example demonstrates how to use the NodeSpacing property to specify the vertical spacing between a node and its adjacent nodes at the same level in the tree.
