ImageView in the Designer

[alfcen]

When I add an ImageView in the Designer it shows up correctly
but any attempt to assign it a bitmap fails. However, when I add
the ImageView programmatically, for instance

Activity.AddView(ImageView1, 60%x, 8%y, 100dip, 100dip)

then it does load the bitmap formidably in either way:

ImageView1.Bitmap = Bitmap, or ImageView1.Bitmap = LoadBitmap(...)

Did I miss something?

It needs a declaration in Globals to be seen by the application. Designer -> Tools -> Generate Members will do this for you to avoid typing it in yourself.

Thanks Andrew. I did declare the ImageView under Globals and also tried "Generate Members" - no change. Anyway, it is easy to work around.

Do you mean in the Designer? It works fine for me

You need to add the image to the image pane with the "Add Images" button and it should then show up for selection up in the "Image File" dropdown in "ImageView properties".

Right, Andrew, it does work in the Designer. Perhaps, if you add an ImageView in the Designer you must add an image to it in the Designer, too.

If you want to assign an image to an ImageView in the code, you should not create the ImageView in the Designer, but in the code only, such as with

Dim ImageView1 As ImageView
Activity.AddView(ImageView1, 0, 0, 100dip, 100dip), and then,
ImageView1.Bitmap = (...)

So, I believe you can either work with the Designer or in the code. In a way, that would make sense.

You can add the same image to both the file manager and the designer. It will work properly.

No, you can add the ImageView in the Designer, without an image, and assign images to it in code as long as you have declared in it Globals so the compiler knows it is there. The Designer Generate Members will do that for you but you need to tick the ones you require.

Haha I just know I can insert image by Designer, I'm so stupid
