How do I change the height of a textbox ?
Neither of the below work:
this.TextBox1.Size = new System.Drawing.Size(173, 100);
I know this is a kind of old post, but I found myself in this same issue, and by investigating a bit I found out that the Height of a WinForms TextBox is actually calculated depending on the size of the font it contains, it's just not quite equal to it.
This guy explains how the calculation is done, and how you can set it on your TextBox to get the desired Height.
Cheers!
