Change the Textbox height?

Question

How do I change the height of a textbox ?

Neither of the below work:

this.TextBox1.Size = new System.Drawing.Size(173, 100);
         


        

Answer 1

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;
            }
        }

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.

Try the following :)

        textBox1.Multiline = true;
        textBox1.Height = 100;
        textBox1.Width = 173;

Answer 4

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.

Answer 5

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;

Answer 6

set the minimum size property

tb_01.MinimumSize = new Size(500, 300);

This is working for me.
