You’ll need to write a labelFunction
Maybe something like this:
function mapCdms(item) : String
{
Return item.accessMap.cdms;
}
…
<mx:DataGridColumn labelFunction=”mapCdms”
… />

Subject: [flexcoders] Re: how to
display the HashMap data in flex <mx:Data Grid>?
matt,Manish Jethani
thank you
the detail what to do is below:
1.the Java method:
public ArrayList
findAllUsers(){
ArrayList list =
new ArrayList();
try{
PreparedStatement pstmt = getDB
().getConnection().prepareStatement(QUERY_ALL);
ResultSet rs = pstmt.executeQuery();
HashMap map = new HashMap();
while(rs.next()){
UserVO user = new
UserVO();
map.put(new
String("crm"),new
Integer(rs.getInt("crm")));
map.put(new String("cdms"),new Integer
(rs.getInt("cdms")));
map.put(new String("farnet"),new Integer
(rs.getInt("farnet")));
map.put(new String("par"),new Integer
(rs.getInt("par")));
map.put(new String("onyx"),new Integer
(rs.getInt("onyx")));
map.put(new String("promo"),new Integer
(rs.getInt("promo")));
user.setNetworkId(rs.getString("network_id"));
user.setFirstName(rs.getString("firstname"));
user.setLastName(rs.getString("lastname"));
user.setLoggedOn(rs.getString("loggedOn"));
user.setActive(rs.getString("active"));
user.setAccessMap(map);
list.add(user);
}
}
catch(Exception
e){
}
finally{
db.close();
}
return list;
}
2.the related flex page:
the object userList is return from the above
method
and I want to display the Object
<mx:DataGrid
id="dgContact" change="selectContact
(dgContact.selectedIndex)" dataProvider="{userList}"
width="100%"
height="100%" toolTip="Contact
List">
<mx:columns>
<mx:Array>
<mx:DataGridColumn columnName="networkId" headerText="Network
ID" marginLeft="4"
width="50"/>
<mx:DataGridColumn columnName="firstName"
headerText="First Name"
marginLeft="4" width="60"/>
<mx:DataGridColumn columnName="lastName"
headerText="Last Name" marginLeft="4"
width="60"/>
<mx:DataGridColumn columnName="active"
headerText="Active"
marginLeft="5" width="50"/>
<mx:DataGridColumn columnName="loggedOn"
headerText="Status" marginLeft="5"
width="50"/>
<mx:DataGridColumn columnName="??????" headerText="crm"
marginLeft="5"
width="70"/>
</mx:Array>
</mx:columns>
</mx:DataGrid>
how to write the ??? and the related actionscript
after got the userList and make the attribute
hashmap to Array? is it ?
