Guys!
I got 2 ajaxToolkit:sliderExtenders "SliderExtenderVertical" and "SliderHorizontal" targeting 2 asp:TextBoxes "SliderVertical" (with definition for "SliderVertical_TextChanged") and "SliderHorizontal" (with definition for "SliderHorizontal_TextChanged") respectively.
However, when "SliderVertical" is slided, both "SliderVertical_TextChanged" and "SliderHorizontal_TextChanged" events are triggered!
How to prevent "SliderHorizontal_TextChanged" event from being fired when "SliderVertical" is slided?
As a matter of fact, when I slide the "SliderHorizontal" only "SliderHorizontal_TextChanged" event is triggered!
Please help.
Thanks.
