WPF Auto height in code

Question

How could I set the value of the Height property of a WPF control in C# code to \"Auto\"?

Answer 1

Perhaps this link will help you.

At times, you may want to programmatically set the Height or Width of a WPF element to Auto in code. To do this, just use the Double.NaN (Not a Number) value.

For example, in C#:

this.txtName.Width = Double.NaN;

Answer 2

You can use

RowDefinition rd = new RowDefinition();  
rd.Height = GridLength.Auto;  
ContentGrid.RowDefinitions.Add(rd);
