How to select a row in JTable

Hello,
I have a problem selecting a row in a JTable.
I use
mytable.getSelectionModel().setSelectionInterval(row, row);
to select a row, but after that this row is only highlighted. After calling this method I cannot change the selection using the arrow keys.
Can anybody give me a hint, how I can get the row selected, so that I can use the arrow keys immediately after selecting the row?
Any help is welcome.
Thanks,
Fritz

Hi Sahoo,
If you are using the class CL_GUI_ALV_GRID. In methods SET_TABLE_FOR_FIRST_DISPLAY.
in layout structure you will find field SEL_MODE
pass :
LS_LAYOUT-SEL_MODE = 'A'.
In PAI.
CALL METHOD GRID->GET_SELECTED_ROWS
    IMPORTING
      ET_INDEX_ROWS = T_ROWS
      ET_ROW_NO     = T_ROWID.
Hope these will solve your problem.

Urgent : how to select the rows in the ALV Grid Control

How to select the rows in the ALV Grid control,
I am facing the situation where i need to select the row/rows in the Grid control and then to lock the entries,
If anyone have the solution please help me out
<b>Its very Urgent</b>

Hi Bharath,
Go through this hope u can understand.
SEL_MODE. Selection mode, determines how rows can be selected. Can have the following values:
A Multiple columns, multiple rows with selection buttons.
B Simple selection, listbox, Single row/column
C Multiple rows without buttons
D Multiple rows with buttons and select all ICON
Setting and getting selected rows (Columns) and read line contents
You can read which rows of the grid that has been selected, and dynamic select rows of the grid using methods get_selected_rows and set_selected_rows. There are similar methods for columns.
Note that the grid table always has the rows in the same sequence as displayed in the grid, thus you can use the index of the selected row(s) to read the information in the rows from the table. In the examples below the grid table is named gi_sflight.
Data declaration:
DATA:
Internal table for indexes of selected rows
gi_index_rows TYPE lvc_t_row,
Information about 1 row
g_selected_row LIKE lvc_s_row.
Example 1: Reading index of selected row(s) and using it to read the grid table
CALL METHOD go_grid->get_selected_rows
    IMPORTING
      et_index_rows = gi_index_rows.
DESCRIBE TABLE gi_index_rows LINES l_lines.
IF l_lines = 0.
    CALL FUNCTION 'POPUP_TO_DISPLAY_TEXT'
         EXPORTING
              textline1 = 'You must choose a valid line'.
    EXIT.
ENDIF.
LOOP AT gi_index_rows INTO g_selected_row.
     READ TABLE gi_sflight INDEX g_selected_row-index INTO g_wa_sflight.
    ENDIF.
ENDLOOP.
Example 2: Set selected row(s).
DESCRIBE TABLE gi_index_rows LINES l_lines.
IF l_lines > 0.
    CALL METHOD go_grid->set_selected_rows
        exporting
          it_index_rows = gi_index_rows.
ENDIF.
Reward points if helpful.

How to select multiple rows from List Of Values

Hello,
I use ADF 11g to create my list of values (LOV). I want to select multiple rows from it. but i can't.
so how i can select many rows to set them in my adf table.
Thank in advance

Hi,
LOV is map to an attribute in the viewObject so it will return only one value or more values from selected row. You can't select multiple rows from LOV.
But you can do this by using popup which you can select multiple rows and insert the selected rows to another table.
This blog post explain how to achieve this :

How to select a row in a single-select table view?

Hello folks,
I have a table view with a 'details' button. When a row is selected and 'details' is pressed, the table view disappears and a form view is displayed (like the toggle button in PCUI). I have implemented this using a navigation link. When I press 'cancel' in the form view, another navigation link takes the user back to the table view.
My problem is, when the table view reappears, there is no row selected (the row that was selected previously, is de-selected). How do I make sure that the row remains selected?
I tried using the collection_wrapper->mark() method in the inbound plug of the table view, but it works only for multi-select table.

Hi Masood,
Thanks for your reply.
I had already tried using MARK ( iv_index = lv_index ), but it did not work because the first statement in the MARK method is
check ME->MULTI_SELECT = ABAP_TRUE.
Mine is a single-select table. So, using the MARK of the iterator object, with either the IV_BO or the IV_INDEX parameter also does not work. Is there any other way for a table with single row selection?
Thanks!!!
Rohan.

How can i add rows to a JTable at run time ??????

hi there
how can i add a row to a JTable at run time? and display the table after the change? thank you.

For adding or removing the rows from the JTable, you have to use the methods on the table model. I would show you a simple implementation of table model.
public class MyTableModel extends AbstractTableModel {
private ArrayList rowsList = null;
private String [] columns = { "Column 1" , "Column 2", "Column 3"};
public MyTableModel() {
rowsList = new ArrayList();
public int getRowCount() {
return rowsList.size();
public int getColumnCount() {
return columns.length;
public void addRow(MyRow myRow) {
//MyRow is any of your object.
rowsList.add(myRow);
fireTableDataChanged();
public void removeRow(int rowIndex) {
rowsList.remove(rowIndex);
fireTableRowsDeleted(rowIndex, rowIndex);
public Object getValueAt(int row, in col) {
MyRow currentRow = (MyRow)rowsList.get(row);
switch (col) {
case 0:
//return the value of first cell
break;
case 1 :
//return the value of second cell
break;
case 2 :
//return the value of third cell
break;
}Then create the table using the TableModel using the constructor new JTable(TableModel) and then when you want to add/remove a row from the table, call myTableModel.addRow(MyRow) or myTableModel.removeRow(rowIndex)....I hope that this solves your problem.
