Control.Hide(), How to query for hidden.

[Jesper, Denmark]

Hi,

How can I query a Windows.Form control if it is hidden or not.

I would like to toogle Hide/Show and not use a bool as control variable for
this but simply query the form werther or not its hidden.

regards than thanks
Jesper.

How can I query a Windows.Form control if it is hidden or not.

The Visible property of the control.

Two places to look for this information in the future:

1) MSDN:

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.hide.aspx

"Hiding the control is equivalent to setting the Visible property to
false. After the Hide method is called, the Visible property returns a
value of false until the Show method is called."

2) If MSDN doesn't have the information you need, try Reflector:

http://www.aisto.com/roeder/dotnet/

....which will give you this as the reflected method body of Hide()

public void Hide()
{
this.Visible = false;
}

Hi,

How do you set it as Visible or Hidden in the first place?
answer:
The only way is setting Visible to true/false
so you have to check the value of this property
