Hello,

I'm implementing "select all" feature for column chooser on the grid.   But the code I wrote is not working.  Here it is :

                  private void Handle_ColumnChooserSelectAll_Click( object sender, EventArgs e )

                  {

                        var visibleColumn       = _columnChooser.ColumnChooserControl.DisplayLayout.Bands[ 0].Columns[ “Visible” ];

                        if ( visibleColumn == null )

                        {

                              return;

                        }

                        // A precaution

                        if ( _columnChooser.ColumnChooserControl.DisplayLayout.Rows.Count == 0 )

                        {

                              return;

                        }

                        // Remember the current row

                        foreach ( var thisRow in _columnChooser.ColumnChooserControl.DisplayLayout.Rows )

                        {

                              // If checked, take no action

                              if ( ( bool )( thisRow.Cells[ visibleColumn.Index ].Value ) )

                              {

                                    continue;

                              }

                              thisRow.Cells [ visibleColumn.Index ].Value = true;

                        }

                        // Go back to the top; hard to reach the old "current row"

                        _columnChooser.ColumnChooserControl.DisplayLayout.Rows[ 0 ].Activate();

                  }

We use this statement  to make the column selected :   " thisRow.Cells [ visibleColumn.Index ].Value = true;",     But after this statement,   the value is still false !   Can anyone help  ?
