WPF禁用窗口自动调整大小

Question

Currently I have

    SizeToContent="WidthAndHeight" 
    ResizeMode="NoResize"

because I want to take advantage of WPF's auto resize. But when I hide some buttons the window width shrinks, this is expected behavior but I would like to disable that. Basically I want the window size to stay as it is after it is rendered. Is there a nice way to do that instead of calculating the width on start up and set it in code behind?

Answer 1

There is nothing wrong with code behind.

But you might want to set your buttons' Visibility to Hidden instead of Collapse to achive the desired behaviour.

Answer 2

You can set the size (fix size) of your window in its load event when the window got its width and height based on the size of its content. You should can use something like this.Width = this.ActualWidth and this.Height= this.ActualHeight, in the load event.

Here is what i do : For Window Set:

 SizeToContent = SizeToContent.WidthAndHeight
 ContentRendered += DisableSizeToContent

Finally disable SizeToContent there:

private static void DisableSizeToContent(object sender, EventArgs e)
{
    if (sender is Window win)
    {                
        win.SizeToContent = SizeToContent.Manual;
    }
}

Still looking a solution for Async Bindings!
