I am trying to implement image as checkbox.
I have a list with 2 columns and I want to display checbox image on right side, as a third column.On clicking that image ,the image will be changed to a different one.
In which way I can do this?
One way to do this would be to create a custom Field that extends BitmapField. This custom field could contain two Bitmap images (one for each state). You might even consider having four images, so that you can indicate when it has focus as well. For example: unchecked-non-focused, unchecked-focused, checked-non-focused, checked-focused.
When you want to change the image (i.e. on a touch event or trackball click) just have your custom Field call setBitmap() with the appropriate bitmap.

I am developing a win32 application and I want to use my own images instead of default + and - signs in tree view.
I also found here that I can use images in four cases-
1)An image, such as an open folder, displayed when the item is selected.
2)An image, such as a closed folder, displayed when the item is not selected.
3)An overlay image that is drawn transparently over the selected or nonselected image.
4)A state image, which is an additional image displayed to the left of the selected or nonselected image. You can use state images, such as checked and cleared check boxes, to indicate application-defined item states.
I found some examples like this one(uses state images) but it seems it is not related to my query.
But I can't find how to replace default + and - signs of tree view with my images.
Please help me out of it. Thanks in advance.
The "expansion" buttons are not drawn using an assigned image list; instead they come from the current theme (or in XP/non-themed, are hard-coded glyphs).
The only way to customize them is to use Custom Draw and draw the tree items yourself.
I'm using the Ajax v.7 version of Bing Maps and want to change the pushpin icon.
I don't want to create new icons nor I want to draw on the canvas.
Is there a way to get some predefined puspins or to change the default one color.
the default one is: http://ecn.dev.virtualearth.net/mapcontrol/v7.0/7.0.20140904153057.64/i/poi_search.png
so i assume there must be others, but how to get them?
thanks
To change the icon you need to either use a URL to an image. Or hide the icon all together and use HTML instead (HTML 5 Canvas, SVG, and symbol fonts all work well). If you have a specific type of pushpin icon you want to create and/or function (i.e. be able to change color), let me know and I'll provide ore details.
I am new to wp7. I want to add three images to my page. But not on a single page. It should be on three pages. When i move the image, at that time, the image is changed and i am on the secong page keeping my header and footer fixed.
So how to add three image in one page?
Why do you want to use scroll-viewer?
1) Try using a pivot control without any pivot headers. Add your images to three different pivot items. In pivot the header and footer you specify will remain fixed, only the content will change.
2) Also you can create a single page. Add three images to a list. Bind it to your image control. On flick gesture, change the image URL hence changing the image being displayed but keeping every thing else constant.
I gave you two approaches, try using any one of them which suits you the best. For further information try studying pivots and flick gestures.
I met a limit with quite typical operation. Simple document:

As you can see, image has right and bottom margins. But... CKEditor image dialogue provides VSpace and HSpace parameters which influence together to Top-Bottom or Left-Right twin values and adds unnecessary top and left margins:

Of course, users won't use pure code to define this in style="..." attribute. So, how to allow users insert images as shown on the first image? Maybe exists CKEditor plugin or patch... and i just can't find it.
Another, maybe even a simpler way, to achieve what you want would be to use a predefined set of styles for images and use the "Styles" combo to apply one of preselected classes. This way the styles used for images could be more consistent.
To see what I mean you can check the "Standard" demo - click on an Image and in the "Styles" combo select "Object styles -> Styled image (right)"
How to check some place is already reserved by some controls before adding a new control to the view.
I have added some buttons in the UIImageView and I want to display some images in a label which I'm getting in a random size from the server.I want to place those images over the empty places in the same view.
After adding the first image in some empty place,how could I know that this place is reserved and I have to place the second image in some other placeand the images and buttons should not overlap over each other.
Can somebody please help me ?
Try using CGRectIntersectsRect on the control's frame property (which it inherits from UIView).

I don't believe this will work for rotated views though...hm.
