Today I downloaded and Installed SL 4.0 Beta SDK on my Windows 64 bit Machine. There are many new features added to it,but i wanted to try simple one and see how this works. so In this Blog post i am going to show sliverlight 4.0 new mouse wheel event.
1) First Download and Install SilverLight 4.0 Beta SDK. you can download SL 4.0 SDK from http://silverlight.net/getstarted/silverlight-4-beta/
After installing first create Silverlight 4.0 project in VS.NET 2010 Beta 2
Make sure that you select Silverlight version 4.0 from dropdown list.
Here i am going to create simple UI which has one </TextBlock> with some text . Now i am going to write code for TextBlock MouseWheelEvent.
In MouseWheelEvent args we could capture the delta (change) value and assign to TextBlock FontSize property. so that when you scroll mouse ball up and down the text on the </TextBlock> UI Element will change as well.
UI – Before MouseWheelEvent
