ui.igTreeGridResizing

ui.igTreeGridResizing_image

The igTreeGrid includes also the column resizing feature. Users can choose to arbitrarily adjust the width of a column or double-click the right border of the column to expand it to the width of the longest string in the column. Further information regarding the classes, options, events, methods and themes of this API are available under the associated tabs above.

The following code snippet demonstrates how to initialize the igTreeGrid control.

    bool
    Default:
    true

    Resize the column to the size of the longest currently visible cell value.
