I have no clue, how can I resize my Window.

Question

Hi Folks,

I just walking around my app. and have no clue how can I implement resizing there.

min size of window should be 800x600
max size of window should be 1680x1050

So, I have a window with AllowsTransparency="True" , but that's not a point.

I need to know how can I re-size my window by using below method for instance:

 private void Button_Maximize(object sender, RoutedEventArgs e)
        {
            if (this.WindowState == WindowState.Maximized)
            {
                this.WindowState = WindowState.Normal;
            }
            else
            {
                this.WindowState = WindowState.Maximized;
            }
        }

thank u in advance,

Answer 1

and what I need to do with all my grids and all other controls, that have hard-coded size ?

Answer 2

Hi Julian,

you can set the min-/max-size directly in XAML. To do so, set the MinHeight/MinWidth/MaxHeight/MaxWidth properties on the window level (i.e. the root node).
As for what the other controls do when your window is being resized - the properties I mentioned can be applied to those in just the same way.
If that doesn't help, try to be more specific.

I can set min/max size directly in xaml, but it's not the point of my question, sorry if it was written not understandable.

My question is, how can I set min/max size directly in code behind.

 private void Button_Maximize(object sender, RoutedEventArgs e)
        {
            if (this.WindowState == WindowState.Maximized)
            {
                //TODO: here should be code that specify MinHeight and MinWidth
                this.WindowState = WindowState.Normal;
            }

            else
            {
                //TODO: here should be code that specify MaxHeight and MaxWidth
                this.WindowState = WindowState.Maximized;
            }
        }

 thanks

Hi Julian,

I'm still uncertain what you might be after. If you don't want users to be able to maximize your window then apply a ResizeMode="NoResize" to your window.
If you want (parts of) your window's content to be of a fixed size regardless of the window's size, you can setup your content accordingly, i.e. you could wrap your content in a grid. Assuming that you have a control that you always want to have a fixed size of 150 by 150, then I'd wrap this in a 9-cell grid and place the content in the fixed size center cell, i.e.:

            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition/>
                    <RowDefinition Height="150"/>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition/>
                    <ColumnDefinition Width="150"/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
               <Button Grid.Row="1" Grid.Column="1" Content="I'll always be 150 by 150"/>
            </Grid>

This way, the button would always be centered in your window. That said, you'd probably want to set the MinHeight/MinWidth to 150 as well, in this case.

If this isn't what you're after, try to describe your scenario or what you'd like to end up with.

Olaf

Hi Julian,

> My question is, how can I set min/max size directly in code behind.

You can set the MaxHeight, MaxWidth, MinHeight and MinWidth property of the Window in code as follows:

 private void Button_Maximize(object sender, RoutedEventArgs e)
 {
      if (this.WindowState == WindowState.Maximized)
      {
                //TODO: here should be code that specify MinHeight and MinWidth
                this.MinHeight =600;
                    this.MinWidth = 800;
                this.WindowState = WindowState.Normal;
      }
      else
      {
                //TODO: here should be code that specify MaxHeight and MaxWidth
                this.MaxHeight = 1050;
                    this.MaxWidth = 1680;
                this.WindowState = WindowState.Maximized;
      }
  }

As rearrange the child controls in the Window when the Window is resized, you can use layout control, e.g. Grid, StackPanel, DockPanel, UniformGrid, etc, to arrage the child controls.

Hope this helps.

Sincerely,
Linda Liu
