panning range and zoom range

[Christopher]

Is there a way to set a panning range for left, right, bottom and top.  I want to restrict a user to only pan to the edge of the map and not off the map.  Also, is there a way to restrict on how far a user can zoom down or up.  I instantiated the event handlers for zooming and panning  but wondering if there is an easier way to set a range.

void

 

 

RadMap1PanningFinished(object sender, RoutedEventArgs e)

 

{
    // TODO: Check if center is within panning range?

 

}

 

 

void RadMap1ZoomChanged(object sender, EventArgs e)

 

{

 

 

    if (this.RadMap1.ZoomLevel > 6)

 

 

 

        this.RadMap1.ZoomLevel = 6;

 

 

 

    if (this.RadMap1.ZoomLevel < 3)

 

 

 

        this.RadMap1.ZoomLevel = 3;

 

}

Please let me know. Thanks

Hi Christopher,

Unfortunately, there is no other way to limit zooming and panning in the current version of the RadMap control. This feature is planned for the future releases.

I'm interested to know when it will be fixed. Because I want to limited the ZoomLevel.
 thanks,

Hello Hayula,

Unfortunately these features aren't highly demanded and will not be included to the 2010.Q3 release. You can check its availability using our PITS:

Hi,

I succeeded to do this partially with RadMap.Provider.MinZoomLevel and RadMap.Provider.MaxZoomLevel .
but now my problem is only with the zoom slider that it is longer than my range.
will it be fixed in the next releases ?

Hi hayula,

Yes, it will be fixed, but I am afraid, not in the 2010.Q3 release. You can check its availability using our PITS:

If you want to limit the zoom levels on your zoom slider, you can create a custom control class that inherits the MapZoomBar like below--

public

 

 

class CustomMapZoomBar : MapZoomBar

 

{

 

 

public bool isTemplateUpdated;

 

 

 

public override void OnApplyTemplate()

 

{

 

 

if (!this.isTemplateUpdated)

 

{

 

 

this.isTemplateUpdated = true;

 

 

 

var slider = this.GetTemplateChild("PART_ZoomSlider") as RadSlider;

 

 

 

if (slider != null)

 

{

 

 

//slider.TickFrequency = 0.5;

 

slider.Minimum = 2;

slider.Maximum = 4;

}

 

 

var btnZoom = this.GetTemplateChild("PART_MapNavigationDropDown") as RadDropDownButton;

 

 

 

if(btnZoom != null)

 

{

btnZoom.ClickMode =

 

ClickMode.Press;

 

}

}

 

 

base.OnApplyTemplate();

 

}

}
