C# how to trigg a key event in a tabcontrol specific tab

ceventskeytabcontrol

I have an tabControl1 in my form with three TabPages named TabPage1, TabPage2 and TabPage3.

When TabPage 2 has focus I need to raise an key event (arrow keys for navigation).
This event should not be raised in the other TabPages.

Anybody know how?

On Selected event handler you can cast the sender to the proper control and check for it's name. If the event is generated from TabPage2 you can fire the key event.

Something like this

private void TabPage_Selected(object sender, EventArgs e)
{
  TabPage source = sender as TabPage;
  if(source.Name.equals("TabPage2"))
    //Do whatever...
}

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

foreach (Suit suit in (Suit[]) Enum.GetValues(typeof(Suit)))
{
}

Note: The cast to (Suit[]) is not strictly necessary, but it does make the code 0.5 ns faster.
