Uppercase Method for Metroframework

Question

I need help in TextBox, where I work in c# using Metroframework.

I need to turn all the typed text into TextBox in capital letters. How can I do?

Answer 1

To make life easier and not need to create the method at all Forms, you can create a new control that inherits from this TextBox that you are using and in it you include the method indicated in the response of our friend jbueno.
Example:

class TextBoxEx : TextBox 
{
    protected override void OnKeyPress(KeyPressEventArgs e)
    {
        base.OnKeyPress(e);

        if (char.IsLetter(e.KeyChar))
            e.KeyChar = Convert.ToChar(e.KeyChar.ToString().ToUpper());
    }
}

If the Framework were to Xaml/WPF:

In the Xaml where the button is, there is the property CharacterCasing which accepts the following values: Upper, Lower and Normal.

Setting this property to the button directly on xaml

<TextBox  CharacterCasing="Upper" /> 

At the moment the user is typing, the letters already appeared in uppercase.
And when you go to recover the value of TextBox in the codebehind he had already seen in capital letters.

Another way to set it would be in the codebehind:

public MainWindow()
{
    InitializeComponent();
    NomeTextBox.CharacterCasing = CharacterCasing.Upper;
}

The MetroFrameWorkdoes not really support this property. So go some suggestions:

1 - You can use the ToUpper(), to capitalize the letters before throwing the dice to the BD.

2 - Start using WPF, is more advanced than WinForms, and gives you more freedom to create. Website recommended to start.

3 - In visual studio 2015, you can create apps/programas with metro style already by default, dispensing with use of frameworks. - News story talking about it.

4 - Framework for WPF Mahapps.

5 - I don’t know your level of knowledge, but if you’re starting out, learn how it works and then use frameworks, and start with WPF, because microsoft itself recommends the use, because WinForms is lagging behind.

An alternative is to change the event KeyPress of your TextBox to capitalize all letters.

private void textBox_KeyPress(object sender, KeyPressEventArgs e)
{
    if (Char.IsLetter(e.KeyChar))
        e.KeyChar = Convert.ToChar(e.KeyChar.ToString().ToUpper());
} 

Perhaps the most viable thing in your case would be to create a new component that inherits the MetroTextBox, then you can overwrite (override) this function and even create a property with the same intention of CharacterCasing so that it is possible to choose Property window if you want him to be case sensitive or not.
