Problem setting Index value on ComboBox

Question

I am running into a problem with setting the index on a
dropdown box. I will try to give as much detail as possible. From
what I can tell, it should be working and does, but only for one
item. If anyone can suggest a different group to post to, let me
know. I can not find a solution anywhere.
I have the following code to show a combobox. The data is
derived from a XML config file. The combobox itself works fine and
does in fact show all of the data from the XML config file.
<mx:HBox>
<mx:Label text="Status" width="55"/>
<mx:ComboBox id="uxstatus" dataProvider="{_xmlVulnStatus}"
labelField="status"/>
</mx:HBox>
The part of the XML config file that is used to populate the
combobox.
<mainconfig>
<vulnstatus>
<status>Open</status>
<status>In Progress</status>
<status>Closed</status>
</vulnstatus>
</mainconfig>
Now, when a user selects an item from a separate datagrid, on
change I have it run the following function. The function reads in
the data, parses it and compares the "status" value from the
datagrid info with the "status" options in the XML config file.
When it matches, it sets the index number for the combobox so it
shows the right data. My problem is below the function.
public function parseMSVulnStatus(evt:Event):void {
var xmlMSV:XML = XML(msdetailed.selectedItem); //the host
dataProvider item
//trace ("MS Vuln status = "+xmlMSV.status);
for ( var MSVi:Number=0; MSVi<_xmlVulnStatus.length();
MSVi++ ) { //loop over the items in the dataProvider
var sDataValueCurMSV:String =
_xmlVulnStatus[MSVi].valueOf(); //get the current item.data value
if ( sDataValueCurMSV == xmlMSV.status ) { //compare desired
value to current item.data value
mx.controls.Alert.show("match found - MS Vuln status =
"+xmlMSV.status +" and MSVi = " +MSVi);
msstatus.selectedIndex = MSVi; //set the seletedIndex of the
combo box
else {msstatus.selectedIndex = -1}
if (msdetailed.selectedItem.falsepos=='Y')
{msfalsepos.selected=true;}
The problem. If the value from the datagrid is "Closed", it
shows the index as being "2" and sets the combobox index
appropriately and displays "Closed". The alert box is displayed
(for testing) to show the values.
If the value from the datagrid is either "Open" or "In
Progress", it does show the proper index as being either 0 or 1,
respectively and shows the alert box. However, the combobox appears
to be set to -1. I have verified the data is set properly in the
database (which is what populates the datagrid).
Any thoughts on this? Based on my alert box, it appears that
the data is seen properly and that it knows how to set the index of
the combobox.... it's just not happening (unless it's "Closed").
Thanks in advance.

Answer 1

you could force a selected index using something like
mydatagrid.selectedIndex=0 or 1 try this pos i made for someone
beacause if you want to cange the value of field based on selection
this could be simpler by using an xml file with all the value for
each record in one object
