When i change the value of a combo box using a property node it displays the value not the item label

I am using a combo box as a select list for text serial commands. I have items like "engineering", "GUI", and "Scan" for the commands "MDE", "MDN", and MDS respectively which i have input as the corresponding value in the combo box. so for example the label "engineering" has the value "MDE" in the combo box items list. when the Vi starts it needs to read the current value MDE, MDN, or MDS and then i want it to display on the front panel the item text corresponding to that command value.
To do this i have tried to read the serial command, ie MDS and then wire that to a "value" property of a property node of the combo-box, but instead of displaying the corresponding item label, "Scan", it displays the value "MDS" on the front panel instead. i want the front panel to use the label text when choosing and displaying but the block diagram to use the serial commands. Can this be done with a combo box? I'm trying to use a combo box so i can keep it all text and avoid having to build a case statement to convert enums or rings from a numerical value to the text command.
The correct text value is wired to the value property and it does exist in the combo-box. I have unchecked "values match items" and selected to not allow undefined values.

Don't use the value property node. Use the Text.Text property node. When creating the property node, select Text, then in the next pop-up box, select Text.

Calling a bean method on select of Combo box item

Hi
On select of Combo box item in a form, text fields in the same form should be populated
dynamically.Is it possible to call a bean method which does this,by calling onSelect() method
of combo box ?
Thanks in advance,
Sridevi

Uff, sorry!
I ment that you write some code for the "onSelect" event which sends a request to the server with the selected value: onSelect="self.location.href='<%= request.getRequestURI()%>?selectedVal= ' + this.selectedIndex;"

How can I display JTextFields correctly on a JPanel using GridBagLayout?

I had some inputfields on a JPanel using the boxLayout. All was ok. Then I decided to change the panellayout to GridBagLayout. The JLabel fields are displayed correctly but the JTextField aren't. They are at the JPanel but have a size of 0??? So we cannot see what we type in these fields... Even when I put some text in the field before putting it on the panel.

Dependent combo boxes using webservice

Hi All,
I'm trying to create a depended combo boxes using af:selectOneChoice, using webservice datacontrol. When i try to change the value of the first combo box which has hard coded values (eg. Continent), The depended combo box (eg.Country) is empty. (which is returned via webservice) When i again change the value of the first combo box, I get the corresponding values(Countries) generated. The very first time when a value is selected is not binded to the model. Why is this happening and how to overcome this issue. I tried using the value change listener and assigned the current value to binding but there was no change in the behaviour.

Thanks for your response Frank. The Sample worked fine. But when i try to implement the same i ran into issues.
First, I created a combo box for continents and a managed bean.
<af:selectOneChoice label="Region" id="soc1" autoSubmit="true"
                              valueChangeListener="#{locateBean.setRegion}">
            <af:selectItem label="Asia" value="Asia" id="si3"/>
            <af:selectItem label="Europe" value="Europe" id="si2"/>
            <af:selectItem label="NA" value="NA" id="si1"/>
          </af:selectOneChoice>Then I created a combo box for countries using the webservice data control.
          <af:selectOneChoice value="#{bindings.Country.inputValue}"
                              label="Country"
                              required="#{bindings.Country.hints.mandatory}"
                              shortDesc="#{bindings.Country.hints.tooltip}"
                              id="soc2" partialTriggers="soc1">
            <f:selectItems value="#{bindings.Country.items}" id="si4"/>
          </af:selectOneChoice>In the managed bean as
    public void setRegion(ValueChangeEvent event) {
        this.region = (String)event.getNewValue();
    }1. When i run and select an continent, the values are not getting populated in the country combo box. If i refresh the page or select another value for the continent, then its is getting populated.
2. When i tried to execute the operation manually at pagedef on value change event,
        OperationBinding operBinding = getBindings().getOperationBinding("GetCountryList");
        operBinding.execute();I'm getting an warning as <FacesCtrlListBinding> <getInputValue> ADFv: Could not find selected item matching value Afghanistan of type: java.lang.String in the list-of-values.Why the value binded to the managed bean or model is not getting updated for the first time. Is this the expected behavior.

Display Record Based on Combo Box Selection

Hi
Using Flash Builder 4.6.
I have a combo box that lists names stored in a mysql database. Once the user selects a name from the combo box, I would like to have the complete record display on a form. Can you please point me in the right direction to accomplish this task?
Thanks

Can't select a combo box?

I'm fairly new to Flash and am having a little problem.
Basically I have a the top of a clipboard visible at the
bottom of the screen. When it is rolled over the clipboard rises up
from the bottom until it is completely visible on the stage. I did
this by creating a movieclip containing the picture of a clipboard
and tweening it to come up, and then reversing it to go back down.
I placed stop actions at the beginning of the movieclip, the fully
visible position, and a gotoAndStop command at the end of the
movieclip to return it to the start. I placed the movieclip on the
stage, and used onRollOver and onRollout events to trigger the
tweens.
To ensure that the bottom of the clipboard isn't visible when
the clipboard is off screen, I added a mask over the stage area so
that only the portion of the clipboard on the stage will ever be
visible.
Here comes the question: Now I need for the clipboard to
display a few questions with combo boxes that the user can select
and choose an answer from when the clipboard is in it's fully
visible position. I can get the questions onto the clipboard by
placing them in their own layer within the movieclip. However, I
can't make the combo boxes selectable. Is this a focus problem? Do
I just have the questions layer in the wrong place? Does any of
this even make sense? Any help would be greatly appreciated.

Hi Dylan2412,
According to your description, you'd like to pass the ComboBox.Text to the second form's TextBox.
In Form1:
private void button1_Click(object sender, EventArgs e)
Form2 f2 = new Form2(this.comboBox1.Text); //pass the comboBox1.Text
f2.Show();
In Form2:
public Form2(string s) //get the string;
InitializeComponent();
this.textBox1.Text = s;
You could get the comBoBox refer to this sample above.
If you have any other concern regarding this issue, please feel free to let me know.

How to populate a list box linked to selection in combo box?

Hi All,
I am a beginner in Xcelsius. I am having problem on how to populate a list box based on the selection on my combo box.
I have a combo box and a list box. The combo box value consist of Countries. Values are:
Singapore
Indonesia
Thailand
When I select, for i.e. Indonesia, I want to populate the list box with all the Postal Code of Indonesia. When I select Thailand, i want to do the same.
Can anyone shed some lights on how to achieve this?
My spreadsheet data is as follow
Country         Postal Code
Singapore     680123
Singapore     680124
Singapore     680125
Indonesia     155123
Indonesia     155124
Indonesia     155125
Indonesia     155126
Thailand       333123
Many Thanks,
Harianto

Hi,
I am detailing the complete steps below:
In the combobox select the entire range of Country while seeing the records from the Combobox, Xcelsius will automatically show the unique values in the selection.
After that in the "Data Insertion" section for Combobox select the "Insertion Type" as "Filtered Rows" (please click on the question mark beside this option and it will show how the selection works).
In the source select the postal code, in the destination select the range which will be used as a data source for the list box.
This will resolve the concern. Please remember to select the question mark beside the "Insertion Type" option, it explains the working in specific details.
Best of luck.

Testing for no selection of combo box - mandatory combo

What si the best way to see if a combo box has not been selected when it does not have a default value?
if (ocombo.Selected.Value="")

Hi,
some solutions
in c#
if (((SAPbouiCOM.ComboBox)(oForm.Items.Item("cmbUID").Specific)).Selected != null) {
in vb6
if (NOT(oForm.Items.Item("cmbUID").Specific.Selected is nothing)) then
you can also try
if( oCombobox.Selected is null)
