hi petr,
i don't want to disable the matrix....only i want to disable a particular column in matrix on the selection of one combobox event.....
Ex:-In a combobox '2' selections are there & in matrix ''2'' columns are there...if 1st selection(in combobox) is selected then in the matrix second column should be disabled & if 2nd selection(in combobox) is selected then in the matrix first column should be disabled.
i have tried this line...
objMatDet.Columns.Item("col_1").Editable= False
but after this change it work fine....thenagain next time when i stop the debug mode of my project & again when i run my project the '2' columns are ALWAYS UNEDITABLE....(i,e the change occured has became constant)...is there any solution ot make the fields uneditable only on the selection event....
regards,
shangai

How to disable certain columns of a Table?

hi all,
I wish to fill a pattern of 8 digital signals (only 1's & 0's) in a Table.
Is there any way to restrict the user from typing char or num other than a 1 or a 0?
Since the table is a string, I'm having confusion how to do this.
Secondly, the table would have by default 12 columns visible on the Front Panel, excluding both the headers.
But the No. of Columns is based on a parameter called Duration that ranges between 4 & 256.
What I want the user to do is to key in 1's & 0's for the Duration chosen.
Since it'll be tedious to key in for large values of Duration, I've given the option of Set Row(s) & Reset Row(s),
that will fill with either 1 or 0 respectively for the chosen Row Value.
Is there any way to disable the remaining columns of the Table, ie, those unfilled columns,
when the user scrolls horizontally? I don't know how to achieve this.
I went thro' the Properties of the Table, I don't understand some of their functionalities,
like SelStart, SelSize etc.
I wonder why a Property like Disable Array Elements for Arrays is not provided for a Table
to Disable the columns we want to do so, or is it my gross ignorance, I don't know.
Experts pls clarify me & help me out.
Regards,
Partha.

Another option is to do this:
Slightly more elegant, but also more potential for bugs (e.g. the users can tab into the column).

You can lower your overhead by using these "professional" looking indicators and controls. They are limited in functions and properties, thereby causing a smaller VI in file size.
Nice. I didn't think about that. Looks like a VI with a single system boolean takes ~20% less space than one with a standard boolean.
P.S. In general, I would say there are considerably better arguments for using system controls than memory issues.

How to disable JTable column?

Hi! this is archana. Pls suggest me how to disable columns of a table except one, so that no other one can modify its cell values.
Help me.

Hi
i dont know whether u r using TableModel or not.
if ur using a customTableModel for ur entries ..
u can implement the following method of
Table Model Interface.
public boolean isCellEditable(int rowIndex, int columnIndex)then implement in such a way that ..
compare always with ur column number and return false.
as follows.
public boolean isCellEditable(int rowIndex, int columnIndex){if (columnIndex ==4 )return false;elsereturn true;}above code makes all cells in the col=4 uneditable.
even u rearrange the cols in table it works as per documentation.
test this .. and let me know whether u succeeded r not.
note: i think The implementation of this method in AbstractTableModel or defaultTableModel
returns true always.
thanks

How to disable JTable Column Dragging (only single column)

How could i disable a single column from being dragged in JTable?
I need to fix the first column from being dragged in JTable and all other columns except the first can be dragged. how would i accomplish this task ?
well, i know how to fix all column in jtable from being dragged using
table.getTableHeader().setReorderingAllowed(false);But dont know how to fix only a single column. is there any method for doing this. or i have to implement any other logic?
Please help me !
Thanks

The question is why do you have this requirement. I figure if the user wants to reorder the colum, let them, the table won't break.
Maybe something like this would be acceptable:
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class FixedColumnScrollPane extends JScrollPane
    public FixedColumnScrollPane(JTable main, int fixedColumns)
        super( main );
        // Use the table to create a new table sharing
        // the DataModel and ListSelectionModel
        JTable fixed = new JTable( main.getModel() );
        fixed.setFocusable( false );
        fixed.setSelectionModel( main.getSelectionModel() );
        fixed.getTableHeader().setReorderingAllowed( false );
//        fixed.getTableHeader().setResizingAllowed( false );
        fixed.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
        main.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
        // Remove the fixed columns from the main table
        for (int i = 0; i < fixedColumns; i++)
            TableColumnModel columnModel = main.getColumnModel();
            columnModel.removeColumn( columnModel.getColumn( 0 ) );
        // Remove the non-fixed columns from the fixed table
        while (fixed.getColumnCount() > fixedColumns)
            TableColumnModel columnModel = fixed.getColumnModel();
            columnModel.removeColumn( columnModel.getColumn( fixedColumns ) );
        // Add the fixed table to the scroll pane
        fixed.setPreferredScrollableViewportSize(fixed.getPreferredSize());
        setRowHeaderView( fixed );
        setCorner(JScrollPane.UPPER_LEFT_CORNER, fixed.getTableHeader());
    public static void main(String[] args)
        // Build your table normally
        JTable table = new JTable(10, 8);
        table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
        JScrollPane scrollPane= new FixedColumnScrollPane(table, 1 );
        JFrame frame = new JFrame("Table Fixed Column Demo");
        frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        frame.getContentPane().add( scrollPane );
        frame.setSize(400, 300);
        frame.setVisible(true);
}Or maybe you should be using a Row Header. A row header is like the column header of JTable. It remains fixed on the left side of the scroll pane. Search the forum for examples using "setrowheaderview".

How to disable a column in Advance Table

Hi All,
I have an advance table, for which one of the column is MessageTextInput I want to disable this column programatically on certain condition for a particular row, is this should be implemented by switcher else is there a better way.
Thanks in advance

switcher is the best way to implement this problem.
You can also use SPEL expression, which is very easy to implement.
Eg,
Set the SPEL expression for readOnly property as ${ReadOnlyFlag} // where readOnlyflag is a boolean attribute in the VO of respective region.

How to disable a Column for a particular row in Advanced Tables

Hi All,
We are using an Advanced Table for search criteria. Our requirement demands to disable a column (we are using messagechoice item in that column) for only first row. We use standard Add Another Row functionality to add the rows.For the remaining rows it (message choice) should be enabled. Can anyone help me to solve.
Regards,
Sundeep

You can either use a Switcher or OADataBoundVariables for this.
Please see the section OADataBoundVariable in the dev guide. Based on certain View Attribute value, you can set the specific column in the table as Read Only.
Switcher can be very similar too. Decide an Attribute for the Switcher and make sure the first row (which you want to disable) has some specific value. All other rows should have some other value. Decode can help you here. Then you would need to create two cases. Under the specific to first row, have a read only item. For the other case, have an enterable item. A little read through of the Switcher chapter in the Dev guide would clarify the doubts if any.

How to disable some "columns to display"?

Hello!
I have one management pack (it's monitor some our network devices), which was written by contractors for our company. This mp have many unnecessary columns in it's view. I deleted some of these <ColumnInfo>
from mp (.xml file). Then I import mp but these columns
have not disappeared.
Can anybody help me? What should I do to remove these columns?
P.S. I know that I can disable them with "Personalize view", but I want to do it
centralized (all of the console users must see these changes).

Hi,
Since the MP was written by contractors, it is better to contact them edit the column.
Meanwhile, after importing the management pack, please re-create monitor for
a test.

HI
Create three attribute in the node which is bound to the table as data source.
say pro1, pro2, and pro3 of type wdy_boolean.
now bind the enabled property of first four column editors to pro1, last 4 to pro2, and pro3 to first 2 and last 2.
then go to the eventhandler of the dropdown 's on select event and write the code to update the values of these attribute
according to the selected value.
here is the sample code.
DATA lo_nd TYPE REF TO if_wd_context_node.
    DATA lo_el TYPE REF TO if_wd_context_element.
        DATA lv_VAL LIKE ls_dealer1-name.
    lo_nd = wd_context->get_child_node( name = 'DEALER1').
lo_el = lo_nd->get_element( ).
    lo_el->get_attribute(
      EXPORTING
        name = `NAME`
      IMPORTING
        value = lv_VAL ).
     DATA PR1 TYPE WDY_BOOLEAN.
     DATA PR2 TYPE WDY_BOOLEAN.
     DATA PR3 TYPE WDY_BOOLEAN.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
IF LV_VAL EQ 'A'.
PR1 = ABAP_FALSE.
PR2 = ABAP_TRUE.
PR3 = ABAP_TRUE.
   ELSEIF LV_VAL EQ 'B'.
PR1 = ABAP_TRUE.
PR2 = ABAP_FALSE.
PR3 = ABAP_TRUE.
ELSEIF LV_VAL EQ 'C'.
PR1 = ABAP_TRUE.
PR2 = ABAP_TRUE.
PR3 = ABAP_FALSE.
ENDIF.
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO1'
   VALUE = PR1
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO2'
   VALUE = PR2
   LO_EL->SET_ATTRIBUTE(
   NAME = 'PRO3'
   VALUE = PR3
