In a USA map, I want to enable highlighting and selection in only few states. How I can do that? Do I need to customize something in the map shape file? Or I can handle in code itself? Please help me.
Hey sorry. Its working :). I was misinterpreted by the mouse over event. Thanks.
Which version of the control are you using? The elements are present during the imported event for me. How are you loading the layer?
As to disabling the hover effect, the control doesn't currently support this functionality. If you would like to request this feature you could go here: http://devcenter.infragistics.com/protected/requestfeature.aspx
No. Its not working. In Map_Imported event, always the Elements count is zero. So all states are always clickable and selectable.
I tried the same code in map_LayoutUpdated event, the IsClickable property is working, but when I mouseover the not allowed states, it should not highlight. But it highlights all the states.
How I can disable highlighting of a state? I dont find any properties for this. Like I want to disable some states.
Do you mean something like this?
