<h1>
Controlling data selection.
</h1>
<p>
Grid has built-in selection model, which supports single and multiple rows selection mode.
You can specify if multiple selection is allowed in 'selection/multiple' property:
</p>
<pre>obj.setProperty("selection/multiple", true);</pre>
<p>
The index of the last selected row is stored in 'selection/index' property:
</p>
<pre>var index = obj.getProperty("selection/index");</pre>
<p>
While 'selection/values' property returns an array of all selected rows:
</p>
<pre>var array = obj.getProperty("selection/values");</pre>
<p>
Grid calls 'selectionChanged' action so you can attach an action handler to process selection event.
</p>
<pre>obj.setAction("selectionChanged", myFunction);</pre>
<p>
Multiple selection is activated if the Ctrl key is pressed during mouse clicks.
</p>

obj.setProperty("row/count", 20);
