Set the width of a control or container similar to Parent.Width, but for the children, like Max(Self.Children.Width)

[Waveflux]

I am building a canvas app.  I have several containers, each of which hold various controls.  

the tree view looks something like this

Container1

Label1

Lable2

Lable3

Label4

Container1_1

Label1_1

Label1_2

If I wanted to set the width Label1 to the width of Container1, I would write the formula: Parent.Width within the width attribute for Label1

But, what I actually want to do is set the container width based on the widest control, something like: Max(Self.Children.Width) within the width attribute for Container1

Is this possible?  I don't see any collections that reference Children or Controls within the formulas available.

Hi @Waveflux ,

You could try this formula on Width property of container control.

Max(Label1.Width,Label2.Width, Label3.Width,……,…….)

Please note that the width of the child control cannot exceed the width of the container.

Thanks for replying.  While your method would work, it requires that I list every control individually.  I'm asking to see if there is a relative identifier for the children of a control, much like Parent is the relative identifier for the parent of a control.

If there isn't, I'll have to either use your method or set it manually.
