How to enable a button on click of an adjoining list box

Hi,
I have a requirement that :
the button "Add to the list" should be enabled only when the user clicks on the list box "product list". This is to ensure that the user is looking at the list before adding a new product.
I tried that the button is disabled by default and then wrote the following line in the list box
onChange="document.forms(0).ADD_TO_LIST.disabled=false;"
But it is not working.
Please guide me
Appreciate your help.
Thanks,
Gary

I question either your competence or the veracity of this claim. A Google search for JavaScript forum returns 19,000,000+ results.
Please reply if you can help.
Thanks for enlightening me that Java script is different than Java.This is the third time now you have been so enlightened.
I am not sure how is it harming you if I post the Java script question here.Please don't be a wank. It is inappropiate for anyone, including you, to ask off topic questions on this, or any other forum. This forum is NOT for JavaScript questions and that is all there is to it.
So now go to Google. Type JavaScript Forum into the search box and find yourself a JavaScript forum and ask your JavaScript question there.
This isn't rocket science and your excuse as to why you haven't done so is at best flimsy but more likely just a lie.

How to enable a button only when a tilelist item is selected

Simple question but it seems quite awkward to me. How do I enable a button only when an item within a tilelist is currently selected?
For example lets say if I have a button called button1 that is disabled by default and a tilelist called tilelist1 what would I have to add into the brackets of the following code (enabled property of the button) to ensure that the button is only enabled when an item in the tilelist is currently selected but disabled when no items are selected:-
enabled="{}"

enabled="{tilelist1.selectedItem}"
that should do it, it's making an implicit comparision with null (tilelist1.selectedItem == null) which will result in a boolean.
SelectedItem is null when nothing is selected , not null when something is.

How to build a button on click of which opens a list below it

Hi,
I have a requirement wherein onclick of button I want to open/close list/popup (which is displayed below button, just like in select list) and can select any item from list to do some action.
It is required urgent. Can anyone guide me please?
Thanks!

This is the wrong place for urgent requests.
Just like select list? Why not select list?
What version are you? If >= 4.x, you can hide a region on entry, then show/refresh region on click of button using dynamic action.

How to Enable a Button

Hello,
I have a little problem to Enable a Button.
I have a Text-Item and a Button in my Form-Modul. I want to write a Code which checks if the Text-Item is Null. If it is then the Button must be enabled.
But which Form-Trigger must I use to do this.

This question is definitely more clear then Sven's;-)
I would use the when-validate-item-trigger on your text field,
and in addition the post-query-trigger if you want to set the
property already when retrieving records from the database.
IF :MY_BLOCK.EINGABE IS NULL THEN
SET_ITEM_INSTANCE_PROPERTY('MY_BLOCK.MY_BUTTON', :SYSTEM.TRIGGER_RECORD, ENABLED, PROPERTY_FALSE);
ELSE
SET_ITEM_INSTANCE_PROPERTY('MY_BLOCK.MY_BUTTON', :SYSTEM.TRIGGER_RECORD, ENABLED, PROPERTY_TRUE);
END IF;

How to identify which button is clicked in an action

Hi,
I am just checking whether it is possible to build calculator or not in webdynpro for abap.
I have some buttons and i have associated same action for all the buttons and in that action i would like to know which button is clicked.
Please let me know the code for that
Thanks
Bala Duvvuri

Hi Bala,
Its possible. Just go to the action handler for the button & read the attribute ID of the WDEVENT which is passed by the framework. This id will contain the id of the button which triggered the event. Consider the code fragment below:
method ONACTIONACTION .
DATA: lv_button_name type string.
lv_button_name = wdevent->get_string( name = 'ID' ).
endmethod.
At the end of execution lv_button_name will have the ID of the button which triggered the event.

Uday

How to determine wich button is clicked?

... and so on. If you have the time the whole thing is
downloadable
here.. Greetings
from Sweden. Here's some of the code...

that is very easy to do that.
First u assign a separate variable for each button (or) keep
an array where its length is total no of buttons instead of
variables.Store 0 as values for all buttons.
When one button is clicked make the index for that button to
1 and if another button is clicked make the index for that button
to 1 and remaining values to 0.
So,write a function to check the values in array and if 1 is
there change the color of that button to grey and other buttons to
black.
Try this and tell me whether it works or not.

How Do I Filter a Report Using a Multi Select List Box and Specifying Date Between Begin Date and End Date

Hope someone can help. I have tried to find the best way to do this and can't seem to make sense of anything. I'm using an Access 2013 Database and I have a report that is based on a query. I've created a Report Criteria Form. I
need the user to be able to select multiple items in a list box and also to enter a Begin Date and End Date. I then need my report to return only the records that meet all selected criteria. It works fine with a ComboBox and 1 selection but can't
get it to work with a List Box so they can select multiple items. Any help is greatly appreciated while I still have hair left.

The query should return all records.
Let's say you have the following controls on your report criteria form:
txtStart: text box, formatted as a date.
txtEnd: text box, formatted as a date.
lbxMulti: multi-select list box.
cmdOpenReport: command button used to open the report.
The text boxes are used to filter the date/time field DateField, and the list box to filter the number field SomeField.
The report to be opened is rptReport.
The On Click event procedure for the command button could look like this:
Private Sub cmdOpenReport_Click()
Dim strWhere As String
Dim strIn As String
Dim varItm As Variant
On Error GoTo ErrHandler
If Not IsNull(Me.txtStart) Then
strWhere = strWhere & " AND [DateField]>=#" & Format(Me.txtStart, "yyyy-mm-dd") & "#"
End If
If Not IsNull(Me.txtEnd) Then
strWhere = strWhere & " AND [DateField]<=#" & Format(Me.txtEnd, "yyyy-mm-dd") & "#"
End If
For Each varItm In Me.lbxMulti.ItemsSelected
strIn = strIn & "," & Me.lbxMulti.ItemData(varItm)
Next varItm
If strIn <> "" Then
' Remove initial comma
strIn = Mid(strIn, 2)
strWhere = strWhere & " AND [SomeField] In (" & strWhere & ")"
End If
If strWhere <> "" Then
' Remove initial " AND "
strWhere = Mid(strWhere, 6)
End If
DoCmd.OpenReport ReportName:="rptMyReport", View:=acViewPreview, WhereCondition:=strWhere
Exit Sub
ErrHandler:
If Err = 2501 Then
' Report cancelled - ignore
Else
MsgBox Err.Description, vbExclamation
End If
End Sub
If SomeField is a text field instead of a number field, change the line
strIn = strIn & "," & Me.lbxMulti.ItemData(varItm)
to
strIn = strIn & "," & Chr(34) & Me.lbxMulti.ItemData(varItm) & Chr(34)

How to extract information in cells of a mult-column list box?

I have multi column list box. At run time this listbox allow me to select entire row (this is fine), how to extract the data from each cell along the selected row? It seems to me that the Multi column Listbox (MCL) is merely a 1D array (I guess index of this 1D array corresponds to row index of the MCL and value of the element corresponds to column index of MCL.)

To extract cell values of the selected row, you can create a property node for the MCL. From this property node, choose "Item Names". This is a 2D array containing all cell values. Index this array with the MCL terminal. Note that you must choose the scalar data type for the MCL. To choose the scalar data type, right click on the MCL and go to "Selection Mode"->"Data Type"->"Scalar".
See attachment written with LabVIEW 6.
I hope it will help you.

How do I select a cell in a multicolumn list box and use scroll horizontal on th

From an event structure, how do I select a cell in a multicolumn list box and use scroll horizontal on the front panel at the same time. I can select a cell from the multicolumn in an event structure, but I cannot move the scroll bar on the front panel when the program is running.
Solved!
Go to Solution.

I'm assuming you're referring to the scrollbar in the multicolumn listbox. What is your code doing when you select a cell? Can you please post your code so we can see the behavior you're describing? It's possible that you're blocking the event structure, as in performing some long operation in the event that's handling the cell selection. In this case the event structure has to wait until the event completes before being able to respond to the next event. You can configure the event to not lock the front panel while waiting for the event to complete.

Twist How to enable Scrolling and Middle Click (open in new tab)

I'm trying to find out if there is a way I can enable the ability to both scroll and middle click on the Twist. On my T420 I have "scrolling smooth" enabled under trackpoint properties (this setting doesn't exist on the Twist). When this is enabled a quick click of the middle button will open a link in a new tab, but pressing the middle button and moving the trackpoint allows me to scroll as expected. On the Twist, pressing the middle button only seems to bring up the scrolling prompt, and there seems to be no way to click.
