Problem with mouseWheel Zoom

[Santiago Dávila]

Telerik Staff

We are working in an application with a radMap with fix size in width and height, empty provider and some information layers on it.
The option IsMouseWheelZoomEnabled is set to true and the clickMode set to none and the zoom is not working with the mouse wheel.
Can you tell me if that´s a known issue or if there´s a way to do that, or maybe a tip and possible solution of why it´s not working.


Thanks in advance

Santiago

What is the Web browser you are testing you Silverlight application in? I also had this problem when testing in Firefox, but the functionality would be fine when I used it in IE8.

I fixed this problem in Firefox by removing the IsMouseWheelEnabled and subscribing to the MouseWheel Event which might also have some problems with Firefox such as firing multiple times rather than just once. If you use a single DispatchTimer similar to the main demo Telerik has provided, that should fix your problems completely.

Hey there

I am working with IE8, and using the MouseWheel Event event it is working fine, but it became a manual procedure, I suppose the property IsMouseWheelZoomEnabled will work in the future.

Thanks.

I have the mouse zoom problem, only with a second map window.  And also doesn't work at all with firefox.

I have a main map window in a xaml page.   zoom in/out works fine with the mouse.   I then have a button which opens a child window which allows some geocoding searching, a datagrid with the results, and another map windows displaying the selected geocode location.  the mouse zoom doesn't work in this case.
IE8.

 

 

<Telerik_Windows_Controls:RadMap Grid.Row="2" Name="GeocodeMap" IsMouseWheelZoomEnabled="True"/>

 

    public partial class GeocodePage : ChildWindow
    {

Hi Damian,

I believe you can use the RadWindow instead of the ChildWindow in your application. I have tested it on IE8 and firefox 3.6.2 and mouse wheel zoom works as expected.

I have attached a sample solution that uses RadWindow for showing the second map to get you started.

Hi Flemming,

We've created a PITS issue #1649. We will fix the problem with mouse wheel zoom on ChildWindows in future releases.
