I have one problem regarding changing the Index of the Dropdownlist.
I have one Asp:Dropdownlist. And on the change of the Index of the dropdownlist, I am using Rad - Loading Panel. And according the field selected from the dropdownlist, my other controls like Textbox, Radiobutton & Date Pickers are being visible and Invisible.
But the prolem is the loading panel is seen along with the control which is already seen right now.
My requirement is when I change the value in the dropdownlist, the loading panel only should be visible and after the loading panel disappers, the controls should appear. How can I do this.
