Calling an event to determine whether there is text on a RichTextBox control

[TechSupportGeek]

Hello world of DaniWeb. If the title of this thread kinda looks complicated, believe me, it's not. This'll be a simple and straightforward question along with a piece of code attached to it. So, how can I determine whether a RichTextBox control contains text or not when functions such as Cut, Clear etc. are used? You'll first notice the Clipboard check, which I got to work. It basically checks whether text is saved on the Clipboard. Just don't worry about that. What I would like to make work is the feature to enable/disable options such as "Cut" and "Clear" when no text is in the RichTextBox control. Hope you know what I mean. Please, I repeat, take a look at the code I wrote myself which apparently doesn't work right (that's why I'm posting on here after all). Thank you in advance.

Private Sub FunctionCheck()
        If Clipboard.ContainsText Then
            PasteToolStripMenuItem.Enabled = True
            ToolStripButton5.Enabled = True
            PasteToolStripMenuItem1.Enabled = True
        End If

        If RichTextBox1.Text Is "" Then
            UndoToolStripMenuItem.Enabled = False
            CutToolStripMenuItem.Enabled = False
            CopyToolStripMenuItem.Enabled = False
            DeleteToolStripMenuItem.Enabled = False
            FindToolStripMenuItem.Enabled = False
            ReplaceToolStripMenuItem.Enabled = False
            SelectAllToolStripMenuItem.Enabled = False
            ToolStripMenuItem2.Enabled = False
            ReadSelectedTextToolStripMenuItem.Enabled = False
            ToolStripButton1.Enabled = False
            ToolStripButton3.Enabled = False
            ToolStripButton4.Enabled = False
            ToolStripButton6.Enabled = False
            ToolStripButton11.Enabled = False
            ToolStripButton12.Enabled = False
            ToolStripDropDownButton1.Enabled = False
            UndoToolStripMenuItem1.Enabled = False
            CutToolStripMenuItem1.Enabled = False
            CopyToolStripMenuItem1.Enabled = False
            DeleteToolStripMenuItem1.Enabled = False
            SelectAllToolStripMenuItem1.Enabled = False
            DeselectAllToolStripMenuItem.Enabled = False
            ReadSelectedTextToolStripMenuItem1.Enabled = False
        ElseIf RichTextBox1.Text IsNot "" Then
            UndoToolStripMenuItem.Enabled = True
            CutToolStripMenuItem.Enabled = True
            CopyToolStripMenuItem.Enabled = True
            DeleteToolStripMenuItem.Enabled = True
            FindToolStripMenuItem.Enabled = True
            ReplaceToolStripMenuItem.Enabled = True

            ToolStripDropDownButton1.Enabled = True
            UndoToolStripMenuItem1.Enabled = True
            CutToolStripMenuItem1.Enabled = True
            CopyToolStripMenuItem1.Enabled = True
            DeleteToolStripMenuItem1.Enabled = True
