I am using Bing Maps v7 and created a draggable pushpin. i have taken code from here.
http://www.garzilla.net/vemaps/Draggable-Push-Pins-with-Bing-Maps-7.aspx
I need to restrict the drag outside of visible map area.
I have a defined map area with zoom pan disabled and with draggable pin where user can put there pin.
issue: pushpin is draggable outside of map then no option to get that back.
On the Pushpin class, you have several events to manage the action that are done on drag start, drag and drag end, see on MSDN: http://msdn.microsoft.com/en-us/library/gg427615.aspx
So, to be simple, all you have to do is to handle the event of your choice (in your case, I would recommend to use drag on the pushpin) and cancel the event or just modify by yourself the location of the pushpin.
See a live example where the pushpin is restricted to a minimal latitude value (you can update the drag event to be able to restrict to a specific area based on your current map view):

Goal:
Update the visual position in bing map.
Problem:
If I add new latitude and logitude coordinate in the textbox, the bing should be displayed but it doesn't work.
Info:
*You need to use your own api key code.

You've added no code to do anything when the text box values are updated. Add events to them. Which event you use is up to you, some to consider, keyup, unfocus, or add an update button. In the event handler, get these values and convert to floats using parseFloat, then set the map view like this map.setView({ center: new Microsoft.Maps.Location(lat, lon) })

I am looking add custom Html elements such as textbox, textarea to bing map pushpin therefore it can be editable when it placed.
problem is can be place push pin with textbox or textarea but it cannot be editable.
This is a limitation of the default infobox class. You can work around this by using the custom infobox module found here: https://bingmapsv7modules.codeplex.com/wikipage?title=Custom%20Infobox%20Control
If you press "Upload your file" in the test code below, the button text should change to "Uploading...", although in Safari it doesn't. Selecting a sufficiently large file should just give you time to observe the button. Comment out map div and it all works fine.
Here's the isolated test code, it took half a day to find that the map could be the cause, but I need to dig deeper. Interestingly, when copying the same code to JSfiddle it will not reproduce the bug, so you'll need to create your own html file.

There were similar questions on SO before, but no solutions.
I'm working on a product that will show information about individual counties in Wisconsin. Is it possible to programmatically write the county's name on the map? The only option I've seen to do this is by creating a tile layer.
I've written a blog post on how to achieve this here: http://rbrundritt.wordpress.com/2012/03/31/label-pushpins-in-bing-maps-v7/
Here is the code sample:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title></title>

<script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script>
<script type="text/javascript">
var map = null;
function GetMap()
{
// Initialize the map
map = new Microsoft.Maps.Map(document.getElementById("myMap"),
{
credentials:"YOUR_BING_MAPS_KEY"
});
var labelPin = new Microsoft.Maps.Pushpin(new Microsoft.Maps.Location(0,0),{
text : 'Custom Label', //The text for the label
typeName : 'labelPin', //Assign a CSS class to the pin
anchor : new Microsoft.Maps.Point(0,0), //Reset the anchor point of the pin to make aligning the text easier.
textOffset : new Microsoft.Maps.Point(-45,0) //Adjust textOffset point for better label positioning
//Adjust the x value as you see fit for better centering of text
});
map.entities.push(labelPin);
}
</script>
<style>
/* Allow div of pushpin to display overflowing content */
.labelPin{
overflow:visible !important;
}
/* Hide the default pushpin, Alternatively point the icon property of the pushpin to a transparent image */
.labelPin img{
display:none;
}
/*Use this to style the text*/
.labelPin div{
white-space:nowrap;
color:blue !important;
}
</style>
</head>
<body onload="GetMap();">
<div id='myMap' style="position:relative; width:800px; height:600px;"></div>
</body>
</html>
Just use a Pushpin with a custom image, and set the custom image to a transparent image, so all you see is the Pushpin text. To make it real easy, you can even specify a base64 encoded transparent image inline directly, as shown below:
var pushpinOptions = {
icon: "data:image/gif;base64,R0lGODlhAQABAIAAAP///////yH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==",/* Transparent 1px x 1px gif with a 1bit palette, created with gimp and encoded with base64 tool in linux.*/
text: 'Your county name goes here',
draggable: false,
visible: true,
};
var pushpin = new Microsoft.Maps.Pushpin(new Microsoft.Maps.Location(47.6, - 122.33), pushpinOptions);
I am not sure what you are using for the back end but the way I would accomplish this is by doing the following:
ajax call back to the server, get an object that returns the following or something similar
{CountyName = 'Iron', latitude = '23', longitude = -100}
on the call back iterate though that and populate custom info boxes.
How to do add multiple pushpins to the Bing map v7 through Ajax API.. ?
They could be loaded from a array, list, json or anywhere else..
could someone provide a small example? Thank you
You can use EntityCollection to add several pins at the same time.
Example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0&mkt=de-de" type="text/javascript" charset="UTF-8"></script>
</head>
<body onload="init()">
<div id="map" style="position: relative; width: 800px; height: 300px;"></div>
<script type="text/javascript">
function init(){
// Initialize the map
var map = new Microsoft.Maps.Map(
document.getElementById("map"),
{
credentials: "YOUR-BING-KEY",
mapTypeId: Microsoft.Maps.MapTypeId.road
}
);
// Creates a collection to store multiple pins
var pins = new Microsoft.Maps.EntityCollection();
// Creates 5 random pins
for (var i = 0; i < 5; i++){
// A random position
var position = new Microsoft.Maps.Location(Math.random() * 45, Math.random() * 90);
// Creates a Pushpin
var pin = new Microsoft.Maps.Pushpin(position);
// Adds the pin to the collection instead of adding it directly to the Map
pins.push(pin);
}
// Adds all pins at once
map.entities.push(pins);
}
</script>
</body>
</html>
Also, here another example using JSON and jQuery.
