  Use the read only property:

  txtCodeNumber.ReadOnly = true;

  Hi,

  Use one of the following lines of code:

  textBox1.Enabled = false; or
  textBox1.ReadOnly = true;

  Each of these lines of code will lock the text box in a different way. Use the Enabled property if you want the user to have no access to the contained text, and use the ReadOnly property if you want to allow the user to highlight and copy the text. In either case, the user will not be able to edit the text.

  Best Regards,
  Amy Peng

  Hi caulson,

  As far as I understood your problem you want your textbox to be locked when text changed in textbox and focus moved to next control here is solution if above is what you looking for.

  Add TextChanged event with textbox you want to lock, make sure textbox AutoPostBack property must be true.

  default.aspx

  <asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"
  ontextchanged="TextBox1_TextChanged"></asp:TextBox>

  code behind C#: default.aspx.cs

  protected void TextBox1_TextChanged(object sender, EventArgs e)
  {
  TextBox1.Enabled = false;
  }
  
  mark as answer and help others 

  If(This is what u looking for)
  Mark Answer Help Others;
  else
  I am sorry I didn't understand your problem;
