Hi All

I have to give a option to the user to select multiple languages from the list.
I have created one container class with textbox and command button. when clicked on command button another form opens whith a list of languages,the user selects it and then selected values get concatenated and displayed in the textbox.
My problem is if the user clicks the command button again, now the previously selected values must appear as selected. This is something i am unable to achieve.

Can any one help me with this

Thanks & Regards
