This sample shows how the different options of the snap grid manager modify how the snapping experience works.
<table>
<tr title="Specifies if the snapping functions are enabled. If not, the original shapes and positions will be returned.">
<td>Enabled:</td>
<td><input type="checkbox" onclick="enabled(this)" checked="checked" title="Enabled" /></td>
</tr>
<tr title="Specifies duplicate sequential positions should be removed when snapping.">
<td>Remove duplicates:</td>
<td><input type="checkbox" onclick="removeDuplicates(this)" checked="checked" title="Remove duplicates" /></td>
</tr>
<tr title="Specifies the size of the snapping grid in pixels. The grid will be square and relative to the nearest integer zoom level. The grid will scale by a factor of 2 relative to physical real-world area with each zoom level.">
<td>Resolution:</td>
<td>
<form oninput="res.value=Resolution.value">
<input type="range" id="Resolution" value="15" min="1" max="100" step="1" oninput="setResolution(this)" onchange="setResolution(this)" title="Resolution" />
<output name="res" for="Resolution">15</output>
</form>
</td>
</tr>
<tr title="Specifies if grid lines should be displayed on the map.">
<td>Show grid:</td>
<td><input type="checkbox" onclick="showGrid(this)" checked="checked" title="Show grid" /></td>
</tr>
<tr title="Specifies if a Douglas-Peucker simplification should occur while snapping to create smoother lines.">
<td>Simplify:</td>
<td><input type="checkbox" onclick="simplify(this)" checked="checked" title="Simplify" /></td>
</tr>

Edit the grid line styles by retrieving the underlying line layer using the <b>getGridLayer</b> function.
The following is an example of how to edit the stroke color.
<table>
<tr title="The color used to outline the line.">
<td>Stroke Color:</td>
<td><input type="color" title="Stroke Color" id="StrokeColor" value="#c3a77e" oninput="editStrokeColor(this)" onchange="editStrokeColor(this)" /></td>
</tr>
