OpenLayers, Bing, continuous map layer - javascript

I'm trying to get the Bing layer continuous in OpenLayers, but I cannot find any solution.
As we can see on example (http://openlayers.org/dev/examples/bing.html), when we scroll the map horizontally or vertically, layer is not continuous as the Google map is (http://openlayers.org/dev/examples/google.html). It's quite weird when we zoom out and the map doesn't fit into viewport leaving blank white background on the left and right side.
Any ideas?
Thank you.

This example shows how to achieve horizontal repeat:

Not sure how to solve the white background when zoomed out, I do not think Openlayers supports this.

Add a back button in google maps

My current implementation is, when I open the html via browser it zooms to North America map with 4 markers. On click of the markers, the maps is zoomed to that location with few more markers added. Now I would like to add a back button so when the button is clicked it should take me to the initial maps page with 4 markers.
Your help is much appreciated.
Thanks,
Chitra
The features of Google Maps API that you will need to use are bounds. For a rough understanding, imagine providing a top left corner point and a bottom right corner point and just telling the viewport to zoom and track to fit them in. There is a good answer here: Google Map API v3 — set bounds and center
As for how you implement the actual button to trigger the feature, that is a separate question and there are many potential solutions. Again, it has already been discussed here: Put a button on top of a google map

Mapbox not drawing all tiles, when inside a Telerik splitter

We have a legacy website from which the powers-that-be have decided we need to remove all of our Google maps, replacing them with maps provided by MapBox. So I'm in the middle of a crash project to swap out the old for the new.
And here's my problem: the old site is written in ASP.NET, making heavy use of Telerik's controls. In this page we have a RadSplitter, and a Google map being drawn in a RadPane.
Swapping out the Google map with the MapBox map was simple enough, except that the MapBox map isn't rendering correctly. Only the tiles along the left edge of the pane are drawing. But - when I resize the browser window, the rest of the tiles draw.
The div is defined with position: absolute, and top, bottom, right, and left set to 0. Which Google maps worked with.
My guess is that Telerik is doing something that is confusing the MapBox rendering code about the actual size of the div. And that when the window resizes, MapBox re-evaluates things, and gets it right.
I've been playing around with this for a couple of hours now, and getting nowhere:
I've tried triggering a resize event in code, and the tiles didn't draw.
I've tried placing the map in a fixed-size div, inside the pane, and the map drew to the edges, and then the div sat inside the pane with scrollbars, which confirms, to me, that I'm dealing with a sizing issue, but I can't have the scrollbars, so
I've tried setting the width and height of the div to the size of the pane, in code, and that didn't trigger the map to draw the missing panes.
I'm running out of ideas.
Is there some event or function on the MapBox renderer that will cause it to redraw the way it does when the browser resizes?
Turns out the answer was pretty simple:
map.invalidateSize();
Edited - a few days layer
Turns out that only works in IE. In Chrome, invalidateSize() doesn't cause the map to properly resize itself.
so the map is being drawn in a pseudo-frame, which is probably throwing off the calculations for what's "visible"...
do you have a way of sharing the actual output HTML? like jsfiddle?
are there any console errors? maybe it's something as simple as you've met your quota for the map tile server...
try a different tile server?

Google Maps: Custom Tiles being pushed up

I'm working on creating custom map tiles (.PNG) which I can show with ImageMapType from the Google Maps API range. In general, the tiles are shown fine and I get the tiles I want with no real problems.
However, an issue which I can not seem to solve at all, is a weird upwards push of the tiles at a single specific zoom level (9). My original tiles do have many gaps for the ocean in them, so I generate blank tiles to fill in the gaps by surrounding my original map tiles with transparent points in a grid.
For testing purposes, and to show you the exact issue, i've made the grid points visible, and quickly taken a snapshot of the upwards push during the transition phase. The top left of the dark region is where the corner was for the previous layer, and after zooming in, the top marked section is where the corner moved it.
After I go past this layer, into layer 10, the corner goes back down a level, to where it would have been if layer 9 wasnt so buggy.
Hope I've provided enough information and I'll be grateful of any advice.
For zoom problem keep one transparent div with z-index and then set map zoom on 9 also hide its zoom control from map By this no one can zoom your map and for tile problem I need its demo page for more information but with this answer i attached a url for your help with full tutorial just check it : https://developers.google.com/maps/documentation/javascript/v2/overlays#Custom_Map_Types

Maps API v3, markers not clickable with user defined tiles

In November 2010 I modified a minecraft-world-map-site for showing huge panorama photos.
My solution for markers worked in November 2010. But now some markers are no more clickable.
Example with JavaScript code inside:
http://dl.dropbox.com/u/6059427/panorama/beispiel/index.html
The markers on the right side of the photo are not clickable.
I have made a test with Firefox 3.6 and Firebug for exploring this map. There are html-canvas-elements with a fix size of 256x256 pixels. Markers on the right outside of this canvas element are not clickable. Markers on the border of this canvas element have the unexpected property, that only the left half of the marker is clickable, but not the right half.
A single tile is not a perfect square: width 337px, height 323px. I use this rectangle size for displaying broad, expanded panorama photos with a quad tree data structure.
I have tried a lot of solutions/improvements - unfortunately without any success.
What is my mistake? How can I resize this html-canvas-element?
Any help would be appreciated. Thank you. - Bye. Georg
since the you claim that the code worked in November, you can try to set an older version (e.g. 3.2) of the maps api. It might fix it. For versioning see: http://code.google.com/apis/maps/documentation/javascript/basics.html#Versioning

OpenLayers zoom style like GoogleMaps

In GoogleMaps when users zooms In/Out using mouse wheel the point under cursor stays the same (its coordinates), but OpenLayers map has different approach - when zooming center of the map is constant. Can one use GoogleMaps zoom style in OpenLayers map?
EDIT:
Actually current behaviour in my OpenLayers is that when I zoom in with some position under the cursor it moves that position to map center on the next zoom level. Probably it is some issue related to my map specific settings (like projection).
I guess you are using OpenLayers.Control.MouseDefaults control for navigation. Well, you shouldn't, because this control is replaced with OpenLayers.Control.Navigation and will be deprecated in OpenLayers 3.0.
A quick look at source code for MouseDefaults shows that it definitely centers map on the cursor position:
defaultWheelDown: function(evt) {
if (this.map.getZoom() > 0) {
this.map.setCenter(this.map.getLonLatFromPixel(evt.xy),
this.map.getZoom() - 1);
}
},
While cursor stays at the same position the map will centered to new location every time you zoom in/out, which is confusing.
OpenLayers.Control.Navigation uses the same approach as Google Maps. OpenStreetMap uses it and you can see that it works the same way here
Actually, when looking at the Basic Example at OpenLayers, it seems like the map zooms around the mouse pointer, just as Google Maps does. Or am I missing some detail in your question?
