grid.selection.getSelected().length on selecting one row - dojo

Question

I have created a dojox.grid.DataGrid and i want to perform some operations on the rows selected by the user, so, i have placed an alert to get the no. of rows selected by the user.
I am using :
var noofrows=grid.selection.getSelected().length;
alert(noofrows);
to get the number of rows selected by the user in the grid.
When the user selects one row the above statement alerts 0 but it should pop-up 1 as 1 row is selected by user.
When user selects multiple rows it pop-ups the correct number of rows selected by the user.
After selecting multiple rows(right result is getting poped-up) when user selects one row it pop-ups the correct output i.e.: 1.
So, basically the issue is when user selects one row for the first time it pop-ups the wrong output(i.e :0).
Here is the grid creation code :
<table id="AA.FavouritesGrid" dojoType="dojox.grid.DataGrid"
region="center"
jsId="table"
id="table"
store="AAFavouritesStore" style="font-size:30px;width:100%;padding:0px;display:0px;">
<thead>
<tr>
<%
String userCode ="";
userCode = request.getUserPrincipal().getName();
try {
Map<String,String> columnNameLabelMap=model.getDynamicNameLabelmap("Favourites", userCode, locale);
// Loop round columns ordered by user
for (Map.Entry<String, String> entry : columnNameLabelMap.entrySet()){
int width = columnDataById.get(entry.getKey()).getWidth();
columnDataById.remove(entry.getKey());
%>
<th field=<%=entry.getKey() %> width="<%=width%>" height="22px" nowrap="nowrap"><%=entry.getValue()%></th>
<%
}
} catch (Exception e) {
System.out.println(e);
}
// Present any left over columns in default order
for (ColumnData entry : columnDataById.values()){
%>
<th field=<%=entry.getId() %> width="<%=entry.getWidth()%>" height="22px" nowrap="nowrap"><%=entry.getName()%></th>
<%
}
%>
<th field="path" hidden="true"></th>
<th field="underwritingYear" hidden="true" ></th>
<th field="lpRCTLobDesc" hidden="true" ></th>
<th field="lpRCTLob" hidden="true" ></th>
</tr>
</thead>
</table>
favContextMenu = dojo.connect(dijit.byId("AA.FavouritesGrid"),"onCellContextMenu", favouritesGridOnContextMenu );
function favouritesGridOnContextMenu(e) {
alert(table.selection.getSelected().length);
}
Please help to resolve the problem
Thanks

Answer 1

Try below 2 ways to get selected item and items.
var e = dijit.byId("addressMapStoreGrid");
if (e.focus.rowIndex < 0) {
alert('Please select one row!');
return;
}
-
var items = grid.selection.getSelected();
