Force Uppercase

Force Uppercase

  Add this code to the KeyPress event:
  
  

  if (char.IsLower(e.KeyChar)) {     e.KeyChar = char.ToUpper(e.KeyChar); }

  or you could just make whatever the user types in, to uppercase after they press a continue button or something.

  Dim theString as string = Me.theTextBox.Text.ToUpper()

  Not a good solution...

  You're converting all the text to upper case. This makes caracter insertion impossible. The cursor won't move....

  Keychar shound't be read-only!!!!

  e.KeyChar is readonly as passed from the base control. The following works in VB.NET:

  If Char.IsLower(e.KeyChar) Then

  e.Handled = True

  SendKeys.Send(Char.ToUpper(e.KeyChar))

  End If

  Found a solution
  
  Add the following code into the textbox's keyup event
  
  

  txtBTAddr1.Text = txtBTAddr1.Text.ToUpper txtBTAddr1.Select(txtBTAddr1.Text.Length, 0)

  I've tried it on a regular WinForms app, in VS2005.
  
  I don't know, it might be a CF or a version problem...

  I have tried this, however it says the KeyChar is ReadOnly
  
  

  Private Sub txtBTAddr1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtBTAddr1.KeyPress         If Char.IsLower(e.KeyChar) Then             e.KeyChar = Char.ToUpper(e.KeyChar)         End If     End Sub

  hello Barry,
  
  Maybe you could use the OpenNETCF.Windows.Forms.TextBox2 control.
  It has a property that configures the character casing that should be used:
  
  textBox.CharacterCasing = CharacterCasing.Upper;
  
  Greetings,

  Add the below code in a css file and add it to your project. Apply this css to the control say a textbox like :
  <asp:TextBox ID="txtSurname" CssClass="TextBoxUpperCase" runat="server" ><asp:TextBox>
