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

Steps    Set the textboxes to multiline Change the height Change the font size   so it fit into the big textboxes  Set the textboxes back to non-multiline

The Simplest Way to do that   Right click on the TextBox  Go to properties  Set Multiline   True   Now you will be able to resize the TextBox vertically as you wish

Some of you were close but changing designer code like that is annoying because you always have to go back and change it again    The original OP was likely using an older version of  net because version 4 autosizes the textbox height to fit the font  but does not size comboboxes and textboxes the same which is a completely different problem but drew me here    This is the problem I faced when placing textboxes next to comboboxes on a form  This is a bit irritating because who wants two controls side-by-side with different heights  Or different fonts to force heights  Step it up Microsoft  this should be simple   I m using  net framework 4 in VS2012 and the following was the simplest solution for me    In the form load event  or anywhere as long as fired after InitializeComponent   textbox AutoSize   false Then set the height to whatever you want  For me I wanted my text boxes and combo boxes to be the same height so textbox height   combobox height did the trick for me   Notes   1  The designer will not be affected so it will require you to start your project to see the end result  so there may be some trial and error   2  Align the tops of your comboboxes and textboxes if you want them to be aligned properly after the resize because the textboxes will grow down

The following code added in your constructor after calling InitializeComponent   will make it possible to programmatically set your text box to the correct height without a  changing the Multiline property  b  having to hardcode a height  or c  mucking with the Designer-generated code  It still isn t necessarily as clean or nice as doing it in a custom control  but it s fairly simple and robust   if  txtbox BorderStyle    BorderStyle None        txtbox BorderStyle   BorderStyle FixedSingle      var heightWithBorder   txtbox ClientRectangle Height      txtbox BorderStyle   BorderStyle None      txtbox AutoSize   false      txtbox Height   heightWithBorder      I decided to make it cleaner and easier to use by putting it in a static class and make it an extension method on TextBox   public static class TextBoxExtensions       public static void CorrectHeight this TextBox txtbox                if  txtbox BorderStyle    BorderStyle None                        txtbox BorderStyle   BorderStyle FixedSingle              var heightWithBorder   txtbox ClientRectangle Height              txtbox BorderStyle   BorderStyle None              txtbox AutoSize   false              txtbox Height   heightWithBorder

for me  the best approach is remove border of the textbox  and place it inside a Panel  which can be customized as you like

AutoSize  Minimum  Maximum does not give flexibility  Use multiline  and handle the enter key event and suppress the keypress  Works great   textBox1 Multiline   true    private void textBox1 KeyDown object sender  KeyEventArgs e                        if  e KeyCode    Keys Enter                                e Handled   true                  e SuppressKeyPress   true

All you have to do is enable the multiline in the properties window  put the size you want in that same window and then in your  cs after the InitializeComponent put txtexample Multiline   false  and so the multiline is not enabled but the size of the txt is as you put it   InitializeComponent    txtEmail Multiline   false  txtPassword Multiline   false

There are two ways to do this     Set the textbox s  multiline  property to true  in this case you don t want to do it so  Set a bigger font size to the textbox   I believe it is the only ways to do it  the bigger font size should automatically fit with the textbox

User · Answer

You can set the MinimumSize and or the MaximumSize properties of the textbox  This does not affect the size immediately  but when you resize the textbox in the forms designer  the size will automatically be adjusted to satisfy the minimum maximum size constraints  This works even when Multiline is set to false and does not depend on the font size

You can put it inside a panel that has the same back color with your desired height  This way has this advantage that the text box can center horizontally  which is not provided by other solutions   You can make it even more natural by using the following methods      private void textBox1 Enter object sender  EventArgs e                 panelTextBox BorderStyle   BorderStyle FixedSingle             private void textBox1 Leave object sender  EventArgs e                panelTextBox BorderStyle   BorderStyle None

So after having the same issue with not being able to adjust height in text box  Width adjustment is fine but height never adjusted with the above suggestions  at least for me   I was finally able to take make it happen  As mentioned above  the issue appeared to be centered around a default font size setting in my text box and the behavior of the text box auto sizing around it  The default font size was tiny  Hence why trying to force the height or even turn off autosizing failed to fix the issue for me   Set the Font properties to the size of your liking and then height change will kick in around the FONT size  automatically  You can still manually set your text box width  Below is snippet I added that worked for me        textBox   New-Object System Windows Forms TextBox  textBox Location   New-Object System Drawing Point 60 300   textBox Size   New-Object System Drawing Size 600 80   textBox Font   New-Object System Drawing Font  Times New Roman  18  System Drawing FontStyle   Regular   textBox Form Font    textbox Font   Please note the Height value in   textBox Size   New-Object System Drawing Size 600 80   is being ignored and the FONT size is actually controlling the height of the text box by autosizing around that font size

This is what worked nicely for me since all I wanted to do was set the height of the textbox  The property is Read-Only and the property is in the Unit class so you can t just set it  So I just created a new Unit and the constructor lets me set the height  then set the textbox to that unit instead   Unit height   txtTextBox Height  double oldHeight   height Value  double newHeight   height Value   20    Added 20 pixels Unit newHeightUnit   new Unit newHeight   txtTextBox Height   newHeightUnit

set the minimum size property  tb 01 MinimumSize   new Size 500  300     This is working for me

User · Answer

Go into yourForm Designer cs Scroll down to your textbox  Example below is for textBox2 object  Add this  this textBox2 AutoSize   false    and set its size to whatever you want  this textBox2 Size   new System Drawing Size 142  27     Will work like a charm - without setting multiline to true  but only until you change any option in designer itself  you will have to set these 2 lines again   I think  this method is still better than multilining  I had a textbox for nickname in my app and with multiline  people sometimes accidentially wrote their names twice  like Thomas nThomas  you saw only one in actual textbox line   With this solution  text is simply hiding to the left after each char too long for width  so its much safer for users  to put inputs

Just found a great little trick to setting a custom height to a textbox   In the designer view  set the minimumSize to whatever you desire  and then completely remove the size setting  This will cause the designer to update with the new minimum settings
