<h2>Demonstrates:</h2>
|
||
|
|
<ul>
|
||
|
|
<li>a filtered Model (DataView) as a data source instead of a simple array</li>
|
||
|
|
<li>grid reacting to model events (onRowCountChanged, onRowsChanged)</li>
|
||
|
|
<li>
|
||
|
|
<b>FAST</b> DataView recalculation and <b>real-time</b> grid updating in response to data changes.<br/>
|
||
|
|
The grid holds <b>50'000</b> rows, yet you are able to sort, filter, scroll, navigate and edit as if it had 50
|
||
|
|
rows.
|
||
|
|
</li>
|
||
|
|
<li>adding new rows, bidirectional sorting</li>
|
||
|
|
<li>column options: cannotTriggerInsert</li>
|
||
|
|
<li>events: onCellChange, onAddNewRow, onKeyDown, onSelectedRowsChanged, onSort</li>
|
||
|
|
<li><font color=red>NOTE:</font> all filters are immediately applied to new/edited rows</li>
|
||
|
|
<li>Handling row selection against model changes.</li>
|
||
|
|
<li>Paging.</li>
|
||
|
|
<li>inline filter panel</li>
