"control size get changes automatically", because that is what it is supposed to do. If you want to limit yourself to a bad design in WPF then use a canvas.

Basically, a good point. But not always. Quite certainly, some controls should never be resized. Please see my answer.

Please see the comments to the question, by Wes Aday and mine.

Short answer: you need to use one of the most practically important XAML attribute value strings: "Auto". If you have a row definition with Height="Auto", its actual height will be defined by the content's controls; if you have a column definition with Width=Auto", its actual width will be defined by controls. Other width/height definitions give more complex behavior.

Background:

In WPF layout, there are too opposite approaches: ether the size of the content defines the size of the controller, or the size of the controller defines the size of the content (if it even fit, but it also can be scaled to any size). Here, by "container", I mean some Panel (Grid is also a Panel) or Window (System.Windows.Controls.ContentControl). The choice is independent for horizontal and vertical direction.

So, the whole behavior will also depend on the Window property SizeToContent:

Solution 1

First Give the Fixed Height and Width to your Controls, which are added that grid. Do not set Alignment Properties to "Stretch" .

Really, really bad advice. It would screw up a fixed-size control, because — how do you know that fixed size? Did you ever tried to solve such problem yourself?
Sorry,
