Disable selecting text in a TextBox

Question

I have a textbox with the following (important) properties:

this.license.Multiline = true;
this.license.ReadOnly = true;
this.license.ScrollBars = System.Win         


        

Answer 1

I came across of this thread for my same issue I faced. Somehow I resolved it as below,

if (sender != null)
                {
                    e.Handled = true;
                    if((sender as TextBox).SelectionLength != 0)
                        (sender as TextBox).SelectionLength = 0;
                }

Verifying if the length changed other than 0, then only set it to 0, resolves the recursive loop.

If you are using XAML / WPF you should use a TextBlock instead of a TextBox.

ONLY IF YOU USE A TEXTBOX AS A DISPLAY AND NOT FOR INPUT - as TextBlock makes it seem as if the text is "engraved" onto the form itself, and not within a textbox. To get a Border around the TextBlock (if you wish), you can either do it :

In XAML such as :

<Border BorderThickness="1" BorderBrush="Gray">
    <TextBlock Background="White" Text="Your Own TextBlock"/>
</Border>

Or dynamically in C# Code:

//Create a Border object
Border border = new Border();
border.BorderThickness = new Thickness(1);
border.BorderBrush = Brushes.Black;

//Create the TextBlock object           
TextBlock tb = new TextBlock();
tb.Background = Brushes.White;
tb.Text = "Your Own TextBlock";

//Make the text block a child to the border
border.Child = tb;

If you put the text into a label and then but the label into a System.Widnows.Forms.Panel control that has AutoScroll turned on you can display the text w/o it being selectable.

Answer 4

Very Easy Solution

Find a Label and into the textbox go to mousedown event and set focus to the label

This is in VB and can be easily converted into C#

Private Sub RichTextBox1_MouseDown(sender As Object, e As MouseEventArgs) Handles RichTextBox1.MouseDown
        Label1.Focus()
    End Sub

Answer 5

private void textBox5_Click(object sender, EventArgs e)
{
    this.textBox5.SelectionStart = this.textBox5.Text.Length;
}

Answer 6

Attach to the SelectionChanged event, and inside the event set e.Handled = true; and the SelectionLength = 0; and that will stop the selection from occuring. This is similar to what it takes to keep a key press from happening.
