Textbox validation border - wpf

I currently have the following red Border, signifying invalid entry, around TextBoxes in an application.
It just doesn't look right to me, it has square borders around rounded corners and the drop shadow is the wrong colour.
What is the best way of achieving a decent looking border around the text boxes?

Extract the TextBox template using Expression Blend and modify the ValidationStates to suit your desires.

This doesn't directly answer your question, but as a user, I almost prefer that the Background color change to a shade of red, with a low opacity value. It catches the eye well without being too "in your face".
That said, can you get the desired Border effect to look better simply by specifying the red border's CornerRadius value, while changing the TextBox's BorderThickness to 0?

How to set text-positions of different controls inside a FlowLayoutPanel, so that they are on a straight line?

In this WinForms-App (not my choice, they made me use WinForms) there is a FlowLayoutPanel filled with a NumericTextBox, a Label and a CheckBox.
Each control has a text which is displayed. The text of the Label is about 3 pt lower than the other texts (image).
Changing the margin of the Label is not an option, because the outcome after changing the font could be unwanted.
Has anyone an idea of how to fix this without changing the margin?
I tried to change the anchoring and docking for the controls in the FlowLayoutPanel, and the outcome that came closest to my expectations was the one in the image.

Label CornerRadius

I have a dockpanel which contains an array of Label (Rectangles) inherited from Border class, which contains CornerRadius property. So, everything is good, but when I start resizing the window, or add the labels to the dockpanel, their size narrows and the Corner remains the same as it was with the bigger label size!! For example, I have a big size label 300*300 with CornerRadius 30. It looks good, but when I resize the window (make it much smaller) it turns into circle.
I tried to implement the special coefficient but nothing helps. Maybe i have made mistake.
Border is "keeping" it's corner radius regardless of it's actual size. And that's usually a good thing.
In your case, I'd use a Path (NOTE: not a Rectangle).
Using Expression Blend, you can draw a Rectangle of a certain size, set it's RadiusX and RadiusY properties and then make a path out of it (there's an option in the menus, under 'Tools', IIRC). The path will scale (and warp) it's corner radius.
Having said that, what do you need this functionality for? Maybe ViewBox will do the job without inheritance?

Silverlight 4: how to highlight control on mouse over

My aim is to get fine control "animation" when it is mouse-over-ed. For example, I have a "map" of controls (game map that represent different type of terrain), each of them is an image with trees/rocks/hills on the green grass or water (lake or see) image of blue/cyan color. When user point any image with mouse it should get shiny: either get more bright background or get a shiny border.
It is hard to say what exactly I want to have (either background change or border), I would like to try each of them and see what is the most appropriate for me.
I am going to have a custom control (MapTile) that will represent a map tile. I know how to catch MouseEnter/MouseLeave events, but not sure how to change control style and if it is a good idea to work with control style in CodeBehind, probably there are better XAML-based solutions.
Could you please help with a solution that provide few goals:
Goal1: Add highlighted border around the control (it will be squares/rectangles, or circles; use what is easier) on mouse enter, remove border on move leave;
Goal2: Change some properties of my CustomControl (for example, background color).
Thank you very much!
1. How to han
You might find it easiest to get hold of Expression Blend and use it to create a custom template for your control.
The Learn Expression Blend page would be a good place to start. Look for tutorials on customising buttons and this is the same sort of thing that you want to do.
You need to use an attached behavior on your control. You don't need to learn Blend for this.
Check this one as an example, but you can search the site for Mouse Over for other examples.

WPF: Changing the look of a Surface Listbox "click-effect"

I'm changing the look of some Controls that I use in my Microsoft Surface Application at the moment. And today I'm working on a SurfaceListBox.
I have the template for it and already changed background and borders and other stuff.
But I really cannot find where I can change the color of the rectangle that appears on the ListBoxItem when you touch the ListBox. At the moment it's just white and I want to change that.
It's not something like the effect that you can see when the item is selected. I already found that and changed that so my selected item now appears in a different color. But the effect in the second when you touch the item stays white.
So where can I change this effect?
If you mean the bright, white highlight that happens when you press your finger against an item you should look into the SurfaceShadowChrome. It's used by (almost) all surface controls to give feedback when the user is pressing on a control.
It does have a Color property that you can modify to suit your needs. Apart from the color, and the tweaking of corner radius and shadow offset, it's not a very flexible decorator. But hopefully, you'll be able to make it do what you need.

DropShadowBitmapEffect Doesn't work on TextBlock

Does anyone know why the DropShadowBitmapEffect and the EmbossBitmapEffect won't work on a TextBlock (not textBOX) in WPF? OuterGlow, Blur and Bevel seem to work fine.
The transparent background brush is apparently not the answer because you can get a dropshadow with a null background brush. The default softness on a dropshadow is 50% and if you have a small font, the softness dissipates the shadow too much. There seems to be a steep drop off around softness of 39% (at which point the shadow more or less disappears). Try setting it to 0 and slowly moving you're way up until you find a number that still shows the shadow.
Yet another note: the softness is definitely a factor, but be aware in Xaml the valid values are really only 0 to 1, but in Blend it shows it as a percentage up to 100. So if you set the value to 100 in Xaml, it will be completely dissipated.
The background brush = transparent solution still may work for the embossing effect
Bitmap effects work by looking at the post-rendered pixels and running standard image manipulation on them. It should only be dependent on the color of the pixels. I wonder if their algorithms don't work well on white. Try changing the color to see if that has an effect -- if it does, you might want to try putting a black panel underneath with drop shadow set on it.
Edit: The questioner found the answer
"Thanks for pointing me in the correct general direction. It wasn't the color of the text or the DropShadow that mattered, what is needed is to make the Background Brush on the TextBlock the Transparent Brush (Alpha = 0) instead of null."
Important Sidenote: you shouldn't really be using BitmapEffects any more. Use the Effect property based on ShaderModel effects introduced in .net 3.5 SP1, it uses hardware rendering and has far better performance.
