My friends,
how to implement expandable and collapsible properties for usercontrol?
I request u to help me in sorting out a solution for a usercontrol made up of two panels.I like to implement expandable and collapsable features to usercontrol.So that the child controls or usercontrols placed below it should shift upwards and downwards.
In the same usercontrol,How can i proceed if i like to resize the usercontrol at design time as well as runtime?
