C# – how to set a TabControl tab to be invisible

ctabcontrolwinforms

In C# using VS2005 I have a Winforms TabControl with 7 tabs, but I want the last tab to be only visible if a certain configuration option is set.

How to make the TabControl only show the first six tabs? In other words, how do I make the seventh tab not visible?

Best Answer

private void HideTab(object sender, EventArgs e)
{
    this.tabControl1.TabPages.Remove(this.tabPage2);
}
private void ShowTab(object sender, EventArgs e)
{
    this.tabControl1.TabPages.Add(this.tabPage2);
}

this.tabPage2 is your 7th tabpage, whatever name you give it.

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)))
