How to close dojox.grid.DataGrid - dojo

Question

I have a grid that populates from a search event and I'd like the option of being able to close the grid by simply adding an X in the top right corner, similar to how you close any browser or window. I thought it would be as easy as adding the X, styling it to my liking and then creating an onclick event that would close or hide the grid... but I can't seem to get that working. Any help would be appreciated.
My JS is:
dojo.require("dojox.grid.DataGrid"); //FindTask
dojo.require("dojo.data.ItemFileReadStore"); //FindTask
dojo.require("esri.tasks.find"); //FindTask
var findTask, findParams;
var grid, store;
var searchExtent;
function doFind() {
//Show datagrid onclick of search button and resize the map div.
esri.show(datagrid);
dojo.style(dojo.byId("content"), "height", "83%");
searchExtent = new esri.geometry.Extent ({
"xmin":-9196258.30121186,"ymin":3361222.57748752,"xmax":-9073959.055955742,"ymax":3442169.390441412,"spatialReference":{"wkid":102100}
});
map.setExtent(searchExtent);
//Set the search text to the value in the box
findParams.searchText = dojo.byId("parcel").value;
grid.showMessage("Loading..."); //Shows the Loading Message until search results are returned.
findTask.execute(findParams,showResults);
}
function showResults(results) {
//This function works with an array of FindResult that the task returns
map.graphics.clear();
var symbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([98,194,204]), 2), new dojo.Color([98,194,204,0.5]));
//create array of attributes
var items = dojo.map(results,function(result){
var graphic = result.feature;
graphic.setSymbol(symbol);
map.graphics.add(graphic);
return result.feature.attributes;
});
//Create data object to be used in store
var data = {
identifier: "Parcel Identification Number", //This field needs to have unique values. USES THE ALIAS!!!
label: "PARCELID", //Name field for display. Not pertinent to a grid but may be used elsewhere.
items: items
};
//Create data store and bind to grid.
store = new dojo.data.ItemFileReadStore({ data:data });
var grid = dijit.byId('grid');
grid.setStore(store);
//Zoom back to the initial map extent
map.setExtent(searchExtent);
}
//Zoom to the parcel when the user clicks a row
function onRowClickHandler(evt){
var clickedTaxLotId = grid.getItem(evt.rowIndex).PARCELID;
var selectedTaxLot;
dojo.forEach(map.graphics.graphics,function(graphic){
if((graphic.attributes) && graphic.attributes.PARCELID === clickedTaxLotId){
selectedTaxLot = graphic;
return;
}
});
var taxLotExtent = selectedTaxLot.geometry.getExtent();
map.setExtent(taxLotExtent);
}
and my HTML is:
<div id ="datagrid" data-dojo-type="dijit.layout.AccordionPane" splitter="true" region="bottom"
style="width:100%; height:125px;">
<table data-dojo-type="dojox.grid.DataGrid" data-dojo-id="grid" id="grid" data-dojo-props="rowsPerPage:'5', rowSelector:'20px'">
<thead>
<tr>
<th field="Parcel Identification Number" width="10%">
Parcel ID
</th>
<th field="Assessing Neighbornood Code" width ="20%">
Neighborhood Code
</th>
<th field="Property Class Code" width="10%">
Property Class
</th>
<th field="Site Address" width="100%">
Address
</th>
</tr>
</thead>
</table>
</div>
This is my best guess at what to add:
<tr>
<td align="right">
<div class="divOk" onclick="dijit.byId('tocDiv').hide();">
OK</div>
</td>
</tr>

Answer 1

I wound up creating a work around for what I want by creating a new column and putting a close icon within the header. I connected it to an function so that when I click it, the grid closes and the map resizes:
function closeGrid() {
esri.hide(datagrid);
dojo.style("map", {"height": "100%"});
}
HTML
<th field="" width="2%"> <div class="GridCloseIcon" title="Close Grid" onclick="closeGrid();"></div>

Answer 2

How about this?
(assuming the OK line actually appears)
HTML
<tr>
<td align="right">
<div class="divOk" onclick="hideGrid();">OK</div>
</td>
</tr>
JS
function hideGrid() {
var widget = dijit.byId('datagrid');
dojo.fadeOut({
node: widget.domNode
}).play();
dojo.style(widget.domNode, 'display', 'none');
}
