Hi guys,
We have discovered a bug in RadSlider in
Q1
2010 release (version 2010.1.309).
PROBLEM
A server error "
Specified cast is not valid." can occur after postback, when you have an invisible RadSlider control (either the slider, or one of its parents, has "
display:none" applied) with items, defined on the page.
SOLUTION
As a workaround, you can execute the following code, when the RadSlider control fires its
load event:
What is Next
The problem is already fixed and the fix will be available in the next
Latest
Internal Build and the first
service pack.
Please accept our sincere apologies for the caused inconvenience.
