Hello,
I have two RadListBoxes and a button in my page, my requirement is after clicking the button the selected items in RadListBox1 should move to RadListBox2.
My problem is every time I click the button its removing already present item in RadListBox2 and adding the the currently selected item of RadListBox1. I want it to append the item to the already existing items of RadListBox2.
Can anyone help me here please.
Thanks,
Saquib
