You can customize the Header Template. You can easily find out the header template in Blend.

I doubt there's any samples available in WPF. Typical applications that do this tend to use fractal mathematics to generate random heightmaps which get transformed into terrains. You might want to google terrain mapping directx to get started.

I'm sorry, but that's your problem. If you can't write the code for yourself, why do you think we will help you cheat? Your homework isn't a test to see if we can write code, it's to see if you can. When I used to do my homework, I did it myself - I didn't expect somebody else to do it for me.

Hi,
I want to cal my event handler when my custom wpf control is deleted from the designer. I want to know which event I need to override? or for which event I should attach my event handler?

Please give some input.

*maybe* the dispose event if you check in there that the control is being run inside the designer. I wouldn't hold my breath tho.

It could almost defitely be checked that way with WinForms, however WPF designers load controls in a much different way (hence Expression Blend), so I don't believe it will work.

Hi,

Dispose event is not implemented for WPF controls. please check this list this gives better explanation for that.

The first event that comes to my mind is Unloaded.

Don't know about that getting raised from the designer(s) though....try it
and let us know!

Hi,

Unloaded will be called in 2 cases in design time.
1. when window is closed
2. when we delete the control in designer.

But in both the cases the even argument values are same. this will not help me to identify which event is occurred, is it deletion or closing of the window.

So I want to know is there any event handler is called when we delete a control from desinger

WPF crop image help!!

Hello,

I recently got a project and I need help how to crop an image, i got all the way where you get the image from browsing to your local disk, and it comes up on the image viewer, but now I need help on this part, I want the user to click on the button to start cropping it, after the user has made a rectangle around the part of the image he wants to crop, click on the button below the start cropping where i guess the button can say "crop it", or just change the start cropping and it turns into "crop it" which i think would be nice. But anyways, after the user clicks on the "crop it" it is now displayed on the imageviewer. How can this be done? hopefully I explained myself clearly, again, just need help on how to do a basic crop image, i looked at a couple of examples:

http://www.codeproject.com/KB/WPF/ImageCropper.aspx#HowItWorks

and

http://www.codeproject.com/KB/WPF/CropAdorner.aspx

but they are no help, they say in there examples its easier... YA right!!! there code doesnt look easy, can anyone give me an easier example and explain in jr. programming terms : )

also I guess a good example about the croping would be like windows paint, how the user presses the button to start cropping then they can save it. etc.

Thank you

Well, some tasks are just more complex than can be explained in 'jr programming terms'. Having said that, all you need to do, is work out where the user clicked on the image and create a new image to that size, doesn't seem that hard to me ?

Hey chris,

Ok i guess that shed some light, but I am wondering how microsoft paint did it, how when you click on the zoom button, the rectangle box appears and when you click on the image with that rectangle box, it zooms in or enhances that part of the image, I am putting it together in my mind that it creates a new image with that size, is that right? if so, just getting it how to do it is a little hard, but correct me if I am wrong, do I figure out how to get that rectangle box to appear, then when the user clicks on that part of the imgae, which i called the image a variable called imageviewed, i just declare a new image or a new instance of the image that will replace the original with the zoom in one correct?

Mark Salsbery22-Dec-08 6:42

It doesn't look like Paint creates a new zoomed image, although that is
a possible approach.

It looks like Paint just stretches the "area-of-interest" designated by the rectangle
to a larger area of the window. There's no interpolation either - looks pretty pixelated.

Sorry,

UPDATE:

Got somewhat the image to expand, but I made a button to do that, which is below, problem is, I want the user to be able to click on the button and it zooms in closer and closer and closer etc until its a spec, same with zoom out. I am doing something wrong because everytime i press the button, it stays that size and doesnt go smaller or bigger. what am i doing wrong : (

buttonzoomin
{
photoviewer1.height = +200;
photoviewer1.width = +200;

}

buttonzoomout
{
photoviewer1.height = 100;
photoviewer1.width = 100;

}

I know i am close but if someone can tell me what am i doing wrong that would be great and save me from pulling any more hair!!

Thank you

What is photoviewer1?

Is that the actual way you coded it?

If you are wanting to increment the size of the image, you need to put the + before the =, i.e. +=. What you have said here is that you want the width and height to be 200.
