Как изменить размер текстового поля

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 ThomasnThomas (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.

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

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!

Steps:

1. Set the textboxes to multiline
2. Change the height
3. Change the font size. (so it fit into the big textboxes)
4. Set the textboxes back to non-multiline

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;
            }
        }

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;
        }
    }
}

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.

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;

I think this should work.

TextBox1.Height = 100;
