Hi Team,

We are evaluating the telerik map features, we don't find any examples for measure the map.
Also we are looking for the rectangular zoom for the map.

is this two  features are  possible in telerik map using openstreetmap. if possible Please provide us some code example so that we can run it and check it the all features.

Also is it possible to have pinpoints onclick infomration in telerik map using openstreetmap.

This is very important for us, so please respond ASAP.

thanks,
vivek.

Hi Team,

1) Measure the openstreemap --> by mouse click you will create tow points, and then on mouse release it should show the distance.

2) Rectangular zoom --> means you will choose some location, suppose you choose Finland and then you will create a Rectangular area by pressing mouse and on release of the mouse the Finland area should zoom in.

We are looking for these two feature, Please respond it.

Thanks,
Vivek

Hello Vivek,

1) You can create the LocationRect instance from two locations and then calculate the distance using Width and Height properties. The LocationRect structure calculates these properties according to the DistanceUnit property of applied MapControl. The sample method is below.
`private` `double` `GetDistance(Location location1, Location location2)`
`{`
`    ``LocationRect rect = ``new` `LocationRect(location1, location2);`
`    ``rect.MapControl = ``this``.radMap;`
`    ``double` `distance = Math.Sqrt(rect.Width * rect.Width + rect.Height * rect.Height);`
`    ``return` `distance;`
`}`

2) The map control contains the "Box Zoom" feature (Rectangular zoom). By default it is enabled automatically when the user holds down the SHIFT key.
- press and hold down the SHIFT key
- press left mouse button
- drag the mouse cursor
You will see the area which will be used for rectangular zoom when you release a mouse button.

Also the RadMap contains the MouseDragMode property.
The property allows using the following values:
- "None"
- "Drag"
- "Select"

When its value is "Select" then the "Box Zoom" feature is enabled for mouse dragging. You can use it to toggle mouse mode between dragging the map and the "Box Zoom" mode.

Best wishes,

Hi Team,

Please let me know if rectangular zoom is possible or not in telerik map.

Rectangular zoom --> means you will choose some location, suppose you choose Finland and then you will create a Rectangular area by pressing mouse and on release of the mouse the Finland area should zoom in.

Thanks,
Vivek

Hi Team,

Somehow your answer not visible. I don't why but I got to know by using view source of the page.

Thanks rectangular zoom is working now.

I got how we can calculate the distance between two points, but how we can put two points on the map and check the distance between these two points.

Please guide in right direction. if you have some sample code please pass over.

Thanks for the help.
Vivek.
