This makes use of two tools, defined in their own files: <a href="ColumnResizingTool.js">ColumnResizingTool.js</a> and <a href="RowResizingTool.js">RowResizingTool.js</a>.
|
|
Each tool adds an <a>Adornment</a> to a selected node that has a resize handle for each column or each row of a "Table" <a>Panel</a>.
|
|
While resizing, you can press the Tab or the Delete key in order to stop the tool and restore the column or row to its natural size.
|
|
</p>
|
|
<p>
|
|
This sample also adds TwoWay Bindings to the <a>RowColumnDefinition.width</a> property for the columns.
|
|
Each column width is stored in the corresponding index of the node data's "widths" property, which must be an Array of numbers.
|
|
The default value is NaN, allowing the column to occupy its natural width.
|
|
Note that there are <b>no</b> Bindings for the row heights.
