Multicolumn list box, "operate value tool" and "active cell"

If I use the "operate value tool" to select a row
of the multicolumn list box, that row gets a dark blue background.
However, I cannot determine which property will tell me what is that row or let me
change that row number. It is not the active cel or "edit position".
I want to programatically change the selection just as the "operate value tool" does. I can change the background color of the cell but the dark blue of the cells selected by the "operate value tool" take precedence and hide my colors.
Extremely frustrated and wishing for Java or C++...

Hi Alan,
Have a look at event structures and invoke nodes (Point to Row Column) and use property nodes. Here is an attachment.

How do i get the data present in the selected row at run time in Multicolumn list box?

Hi,
I am using multicolumn list box with three columns and i am having OK button.
If the user selects particular row and then press ok then that row datas(that 3 values) has to get update in the file.
Can u tell me how to get that selected row values alone and also how to append the list box value at run time?
Thanks
Meenatchi

You can simply use the Value property of the MLBox to get the row selected & wire it to the Delete from array function with the Itemnames of the MLBox as the Input & Output of the Delate from array function.
See the attached VI.

Your question title & the message you ve posted are contradictory to each other.
Normally a Multicolumn Listbox is a non-editable one, in that while you run you wont get the labeling tool to type some text.
I think you can instead use a Table to achieve your purpose. Also see the below link.

How to add a list box with values for a ztable in SM30

Hello Gurus,
I had created a table maintenance for Ztable and added many extra functionality to that. Now i would like to add a list box or check table for a field. Can i do that with out Regenerating my table maintenance. Please help me its..very urgent.

Have referred this domain to the data element, this should be the Field type in ur table for the particular field.
Eg: <b>SE11 > table name > fields-ZTEST > fieldtype-ZZTEST</b>
ZZTEST in the data element > create a domain for this data element and in that specify teh value range.
Save and activate it.
Make sure that u regenerate teh table maintenance generator else u cant see the changes.
Now if u press F4 u can see only thevalues specified, also u will see only the list box with values in SM30.
Try this,please let me know if u face any difficulties.

How to attach customize symbol in multicolumn list box in labview 7.1?

Hi
I have imported some icons in symbol ring constant but when i want to show them in multicolumn list box by connecting it in the property of ItemSymbol in the form of array,its not showing icons..it takes its default icons placed on that number position ..i want to show my customized icons which i have imported on position 1,2,and 3..i used "import pic" property of the symbol ring constant ...i m using Labview 7.1...
thanks...

u ??
plz???
Please use full words and not text speak.
How did you customize the symbols in your constants? Do the same for the Listbox control.
To programmatically load custom symbols for the listbox control, there are some Invoke nodes that will let you do that such as Custom Items Symbols.Set Symbol Array

A couple of mistakes.
You initialize an array of 5 records with 10 elements instead of vice versa.
Dennis is right, use "spreadsheet string to array" instead. Here's a quick draft (note that the delimiter is set to \'codes, it's a space constant)
Is this loop interactive, i.e. does it need to update the records as the arrive with each iteration? If this is not the case, you should update the ItemNames only once after the loop has finished. For example as follows.

Select multiple items from a list box as values for a parameter of crystal report and Oracle procedure

- I have a Product list box (asp.net) used as multiple selected values for a parameter.
- The Product ID is defined in the Oracle procedure as NUMBER data type.
- In my crystal report, I have a parameter field allow multiple values as p_product_id type as Number. This is the code in my Record Selection Formula for the report:
({?p_product_id}[1] = -1 OR {Procedure_name.product_id} in {p_product_id})
- In C#, this is my code
List<decimal?> productUnit = new List<decimal?>();
int counter = 0;
decimal prod;
for (int i = 0; i < lstProducts.Items.Count; i++)
              if (lstProducts.Items[i].Selected)
                            if (decimal.TryParse(lstProduct.Items[i].Value, out prod))
                                productUnit.Add((decimal?)prod);
                                counter++;
       if (counter == 0)
                   productUnit.Add(-1);
ReportingDAO rDataFactory = new ReportingDAO();
retVal = rDataFactory.GetProductReport(productUnit);
public CrystalDecisions.CrystalReports.Engine.ReportDocument GetProductReport(List<decimal?> productUnit)
          CrystalDecisions.CrystalReports.Engine.ReportDocument retVal = new rptProductDownload();
          ReportLogon rptLog = new ReportLogon();
         rptLog.Logon(retVal, "RPT_PRODUCT_DOWNLOAD");
         retVal.SetParameterValue("p_product_id", productUnit);
I keep having the "Value does not fall within the expected range" when I debug. My question is, is the data type I used for procedure/Crystal report/ and C# correct ? I always have problem with the data type. Any help would be
appreciated
Thank you

List Box showing Value and Display members?

Ok this is a CONCEPT problem (the code is not professional, just read it for the concept, though it does compile and run).
Right, I have asked many people on IRC and no one is giving me a straight answer lol so maybe some professionals can help me.
I am trying to use a Datasource property for my combobox. This is so I can just pass an entire KeyValue pair with indexes and values to be shown in the listbox.
Creating the keyvaluepair as a WHOLE and passing that to datasource property works perfectly.
Creating a keyvaluepair PROCEDURALLY (in a loop or w/e) ends in the datasource property ToString()ing it, list box items show BOTH value AND display members in square brackets as an entire option.
NOTE: Getting the lsitbox.value results in ONLY the valuemember being returned even though the listbox shows both the valuemembers AND the displaymember? it knows they are different?
Now, I dont want any alternatives or comments about the quality of the code, all I want to know is WHY is it doing this, it seems compeltely illogical that the same TYPE and Values and can different Effects within the datasource property? Its like it knows
it was built procedurally?
Anyway here is some code for reference:
// Windows Form
namespace skbtInstaller
public partial class frmMainWindow : Form
public frmMainWindow()
InitializeComponent();
// coxArmaPath = Combo Box (simple drop down)
this.cBoxArmaPath.ValueMember = "Key";
this.cBoxArmaPath.DisplayMember = "Value";
public void addServerPathItem(String Key, String Value)
this.cBoxArmaPath.Items.Add(new KeyValuePair<String, String>(Key,Value));
// This works fine, only the "DisplayMember" is displayed and the "ValueMember" is hidden.
// This acts differently with the same types???
public void setServerPathDatasource(List<KeyValuePair<String, String>> source)
this.cBoxArmaPath.DataSource = new BindingSource(source, null);
public class skbtServerControl
private frmMainWindow frmMainWindowHandle;
public void refreshformWindow()
// Clear Drop Box (empties drop box)
this.frmMainWindowHandle.clearPathBox();
//skbtServerConfig is very simple property object
foreach (KeyValuePair<String, skbtServerConfig> pair in CoreConfig.getServerConfigList())
// Populate Drop Box
this.frmMainWindowHandle.addServerPathItem(pair.Key, pair.Value.getTextualName()); // this works as intended
// cBox gets items like: Some Display Text, Some Display Text, Some Display Text (PERFECT!)
// This works absolutely fine. ValueMembers are hidden.
public void refreshformWindowWithSTATICDatasource()
// Clear Drop Box
this.frmMainWindowHandle.clearPathBox();
var pathDataSource = new List<KeyValuePair<String, String>>()
new KeyValuePair<String, String>("testKey1", "somevalue1"),
new KeyValuePair<String, String>("testKey2", "somevalue2"),
new KeyValuePair<String, String>("testKey3", "somevalue3")
// Populate Drop Box
this.frmMainWindowHandle.setServerPathDatasource(pathDataSource);
// cBox gets items like: Some Display Text, Some Display Text, Some Display Text (PERFECT!)
// ** HERE IS THE PROBLEM?? **
// This creates a type that seems different to the above function which works fine...
public void refreshformWindowWithDatasource()
// Clear Drop Box
this.frmMainWindowHandle.clearPathBox();
var pathDataSource = new List<KeyValuePair<String, String>>();
//skbtServerConfig is very simple property object
foreach (KeyValuePair<String, skbtServerConfig> pair in CoreConfig.getServerConfigList())
pathDataSource.Add(new KeyValuePair<String, String>(pair.Key, pair.Value.getTextualName()));
// Populate Drop Box
this.frmMainWindowHandle.setServerPathDatasource(pathDataSource);
// cBox gets items like [asjAETJQ5785d45,Some Display Text], [asawfgQ5785d45,Some Display Text], [asjAhrrQ5785d45,Some Display Text]
// ????? surely this function should act exactly like the function above??
Thanks!
(I have posted on codeproject too, will condense any replies).

Thanks Michael!
I did debug this and it turns out when i set a new BindingSource to the combo box, indeed the DisplayMember gets reset. Oddly though, the ValueMember stays the same.
I have fixed this with setting the Members before every new bindingSource is set to the combobox, strange that only the displaymember is reset?

public class skbtServerConfig
private String name;
public skbtServerConfig(String name)
this.name = name;
public String getTextualName()
return this.name;
Talking with someone it seems logical that every time I set a new BindingSource the component will not know if I want to keep the same member values so it resets them, but why it only resets displaymember? very strange to me.
Thanks again.

Multicolumn list box selection of Complete Row

Hi guys ,
I want to know that is there a way to select a complete Row from MultiColum List Box Or Table on the Front Penal and then paste on the next row. Its kinda same as microsoft Excel when you select a complete row and coloum and then paste it back to any other row or column and all the values are pasted. The program i am working on requires me to write bunch of values all together in the multi column list box and then copy the same values with jsut a little change(maybe in just one column) and then write them again ..
Thanks
Regards

Multiple Select List Box default value ysing Fx or Code

Hello,
If anybody could help me in figuring out how to set default or customized values (checked) for a multiple select list box in infopath based on a values in a secondary data connection using the fx function or code, instead of manually typing in text in the
default value function, it would be really helpful. Have been stuck for eternity in this
I have a temp table now which has each student name and the subject separtely
something like this
Student Name Subject
AA
English
AA Maths
So that in my infopath form if I choose a student name in a drop
down box the multiple selection list box has the values of the subject chosen by the student checked

Hi,
Please check the link below and see if it can meet your requirement:
http://basquang.wordpress.com/2010/03/29/cascading-drop-down-list-in-sharepoint-2010-using-infopath-2010/
Here is the design for your scenario:
List1 for subject name
List2 for student and subject (just as your temp table)
Then you could create cascading drop-down in InfoPath form.
