Page layout

StackPanel layout

<Grid>

<stackpanel orientation= "Horizontal" >//Sub-elements portrait arrangement

<Button.Content>

<image source= "1.jpg"/>

</Button.Content>

</StackPanel>

</Grid>

<textblock verticalalignment= "center"/>//perpendicular to its way: centered

<textblock horizontalalignment= "center"/>//Horizontal centering mode

<textblock margin= "5"/>//width around the distance

Grid layout

<grod >

<Grid.ColumnDefinitions>//define two columns

<columndefinition width= "/>"

<ColumnDefinition/>

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>//define two lines

<rowdefinition height= "/>"

<RowDefinition/>

</Grid.RowDefinitons>

<button grid.row= "1" grid.column= "1"/>

<textbox background= "Red" text= "Hello" grid.column= "2" grid.row= "1" grid.columnspan= "2"/>//Occupy two columns

</Grid>

To add controls to the layout dynamically:

<stackpanel name= "SP1" mouseenter= "sq1_mouseenter/" >

In the container's Mouse move event:

button Btn1=new button (); Dynamically creating controls

Btn1. content= "New Button";

SP1. Children.add (BTN1); Adding a control to the StackPanel of the container's parent control

Automatically add a button control each time you mouse over the container

To dynamically generate rows and columns:

<grid name= "Gridgame" >

</Grid>

In the Window_Loaded event

for (int i=0;i<10;i++)

{

ColumnDefinition coldef=new columndefinition ();

GRIDGAME.COLUMNDEFINITION.ADD (COLDEF);

RowDefinition rowdef=new rowdefinition ();

GRIDGAME.ROWDEFINITION.ADD (ROWDEF);
}

for (int i=0;i<10;i++)

{

for (int j=0;j<10;j++)

{

button Btn=new button ();

Btn. content=i+ "," +J;

Grid.setrow (btn,1);//Modify the control's Grid.Row property by code

Grid.setcolumn (BTN,J);

GRIDGAME.CHILDREN.ADD (BTN);

}

}

Change the button above to a picture:

Image img=new image ();

Img. Source=new BitmapImage (New Url ("1.jpg", urlkind.relative));

Grid.setrow (Img,i);

Grid.setcolumn (IMG,J);

GRIDGAME.CHILDREN.ADD (Image);

Randomly display a picture:

Random random=new random ();

int Imgname=random. Next (1,10); Generates a >=1, <10 random number

Img. Source=new BitmapImage (New Url ("images/" +imagename+ ". jpg", urlkind.relative));

All the controls can be new

About nesting of layouts:

StackPanel and grids can be nested or nested with each other
