Description

Expand/Collapse image

The expansion indicator image shown above is the built-in image used with the Default visual style. To use a different image for expanding, set the ExpandedImageUrl property to the path of the image. To use a different image for collapsing, set the CollapsedImageUrl to the path of the image. Note that if the CollapsedImageUrl or ExpandedImageUrl are not specified, the default expand/collapse image is used instead.

Node image

You can specify an image to display next to the node text by using the ImageUrl property.

Node text

The node text is the text that appears on the C1TreeViewNode object. The node text can behave like a hyperlink when the NavigateUrl property is set or like a button when the C1TreeViewNode is in selection mode. When an image and text are used for the C1TreeViwNode the text appears to the right of the image.

Checkbox

Check boxes allow the user to select a node or multiple nodes at once which is helpful for interfaces like a newsgroup tree. To enable check boxes set the ShowCheckBoxes to True.

Hierarchical lines

The ShowLines property is useful when you would like to see the hierarchical relationship between the objects. By setting the ShowLines property to True you get a clear picture of the hierarchical relationship for each object.
