Show Tooltip at specific control position via code

I have a textBox that should display a tooltip with a explanation when the user types something wrong.

But i'm not able to put the tooltip in the correct position.

My text Box is inside a groupBox and a TabControl. I tried this:

Point locationOnForm = new Point(this.Left + tabCon.Left + gbDocs.Left + tbKey.Left, this.Top + tabCon.Top + gbDocs.Top + tbKey.Top);

tooltipError.Show("Test", this, locationOnForm , 3000);

But the position is always nearby, never in the right spot.

This will position your tool tip on the right of your text box

tooltipError.Show("TT Text", myGroupBox, textBox1.Left + textBox1.Width + 5, textBox1.Top, 3000);

Notice - you need to set your GroupBox as window - your tool tip must be displayed in the same coordinates as text box. Works well.

On this note, why not use ErrorProvider, which specifically designed for this?

You can get absolute positioning quite easily. This example puts the ToolTip at the bottom-right corner of the TextBox.

Point pt = new Point(0, 0);
pt.Offset(textBox1.Width - 1, textBox1.Height - 1);
toolTipError.Show("Test", textBox1, pt, 3000);

Remember that the Point you provide to tooltip is relative to the Control you provide, in this case textBox1.
