Problem with F# and Pro WPF in C# 2008
f#wpfc#

I had a problem with F#. The lbl1 and txt1 would not appeared.

#light

open System

open System.Windows

open System.Windows.Controls

open System.Windows.Media

let grid1 =

let temp = Grid(Margin=new Thickness(3.0),

Background=Brushes.LightYellow,

ShowGridLines=true)

let col1 = new ColumnDefinition(

Width=new GridLength(1.0, GridUnitType.Auto),

SharedSizeGroup="TextLabel")

let col2 = new ColumnDefinition()

temp.ColumnDefinitions.Add(col1)

temp.ColumnDefinitions.Add(col2)

let lbl1 = new Label(Margin=new Thickness(5.0),

Content="A very long bit of text.")

Grid.SetColumn(lbl1, 0)

let txt2 = new TextBox(Margin=new Thickness(5.0),

Text="A text box.")

Grid.SetColumn(txt2, 1)

temp

let grid =

let temp = Grid(Margin=new Thickness(3.0))

Grid.SetIsSharedSizeScope(temp, true)

let row1 = new RowDefinition()

let row2 = new RowDefinition(

Height=new GridLength(1.0, GridUnitType.Auto))

temp.RowDefinitions.Add(row1)

temp.RowDefinitions.Add(row2)

temp

grid.Children.Add(grid1) |> ignore

[<STAThread>]

do

let window = Window(WindowStartupLocation=

WindowStartupLocation.CenterScreen,

Title="Grid Panel - Shared Size Group",

Width=450.0, Height=300.0, Content=grid)

window |> (Application()).Run |> ignore

.

What I think you're missing is, before you call Grid.SetColumn(lbl1, 0), you need to make lbl1 a child of grid1- in other words, call

temp.Children.Add(lbl1) |> ignore

before

Grid.SetColumn(lbl1, 0)

and do the same thing for txt2.

(And then you'll probably do the reverse when you add grid1 to grid, since it looks like you plan to add another Grid to the second row in grid. You have the child relationship set up, but no row is set.)
