I want to understand how RowDefinition in XAML works. Is the Height label a percentage or a pixel size?

0	Rowdefinition is used to set the height of a row in a grid. This value can be an exact value or a ratio. <RowDefinition Height="50"/> <RowDefinition Height=""/> <RowDefinition Height="3"/> In the above case 1st row value is absolute or fixed, them from the remaining space 2nd row height will be 25% and 3rd row will be 75%. By default it is pixel but you are free to use other units like in , cm , pt. <RowDefinition Height="50 in"/> <RowDefinition Height="50 pt"/> <RowDefinition Height="50 cm"/> Zhang JingChu, if this helps please login to Mark As Answer. \| Alert Moderator

Rowdefinition is used to set the height of a row in a grid.
This value can be an exact value or a ratio.

<RowDefinition Height="50"/>

<RowDefinition Height="*"/>

<RowDefinition Height="3*"/>

In the above case 1st row value is absolute or fixed, them from the remaining space 2nd row height will be 25% and 3rd row will be 75%.
By default it is pixel but you are free to use other units like in , cm , pt.

<RowDefinition Height="50 in"/>

<RowDefinition Height="50 pt"/>

<RowDefinition Height="50 cm"/>

0	Can height of a row and width of a column be changed dynamically at runtime? Zhang JingChu, if this helps please login to Mark As Answer. \| Alert Moderator

0	Yes you can change those in runtime XAML <RowDefinition x:Name="row1" Height=""></RowDefinition> You can choose different unit type from the GridUnitType enum with a value. C# row1.Height = new GridLength(200); row1.Height = new GridLength(200, GridUnitType.Pixel); row1.Height = new GridLength(3,GridUnitType.Star); Thanks, Debata Zhang JingChu, if this helps please login to Mark As Answer*. \| Alert Moderator

Yes you can change those in runtime
XAML

<RowDefinition x:Name="row1" Height="*"></RowDefinition>

You can choose different unit type from the GridUnitType enum with a value.
C#

row1.Height = new GridLength(200);

row1.Height = new GridLength(200, GridUnitType.Pixel);

row1.Height = new GridLength(3,GridUnitType.Star);

Thanks,
Debata
