[CLOSED] Gridpanel with ImageCommandColumn: show Image just if row is selected

[stupp]

Hello everyone,

I have a gridpanel with two imagecommandcolumns.
I just want to show the images, if the row is selected. Otherwise the images should not be shown.

I found something like

var prepareCommand = function (grid, command, record, row) {
            command.hidden = !grid.getSelection().isSelected(record);
        };

        var refresh = function (selModel, rowIndex, record) {
           App.tourSubscriptionGridPanel.view.refresh(App.tourSubscriptionGridPanel.store.getAt(rowIndex));
        };

but it didn't work for me.

Thank you for an advice,
stupp
