Bunifu Framework TextBox是否缺失SelectAll函数？点击后如何调用该函数？

Hey there! Let's break down your two questions about Bunifu Framework's TextBox clearly:

Question 1: Does Bunifu Framework's "Text Box" lack the SelectAll() function? #

Good question! The Bunifu TextBox doesn’t actually lack the SelectAll() function. It’s built on top of the standard .NET WinForms TextBox, so this core capability is fully intact.

In most recent versions of Bunifu Framework, you can call SelectAll() directly on your BunifuTextBox instance. If you’re working with an older version and the direct call doesn’t work, you can access the underlying native TextBox control via the TextBoxCore property and invoke SelectAll() on that instead.

Question 2: How to call SelectAll() when clicking a Bunifu TextBox to select all text? #

To make all text in the BunifuTextBox select automatically when you click it, you’ll need to use the control’s event handlers. Here’s a straightforward way to do it:

• Designer setup steps:

  1. Select your BunifuTextBox control in the form designer.
  2. Open the Properties window, switch to the Events tab (marked by a lightning bolt icon).
  3. Double-click the Click event to generate an event handler in your code file.

• Code implementation:
  Add this code to the generated handler:

  private void bunifuTextBox1_Click(object sender, EventArgs e)
  {
      // Try direct call first (works for recent Bunifu versions)
      bunifuTextBox1.SelectAll();
      
      // Fallback for older versions
      // bunifuTextBox1.TextBoxCore.SelectAll();
  }
  

  A quick alternative: If you want the text to select whenever the control gains focus (like when tabbing into it), use the Enter event instead of Click—it’s more reliable for broader focus scenarios. The code would be nearly identical:

  private void bunifuTextBox1_Enter(object sender, EventArgs e)
  {
      bunifuTextBox1.SelectAll();
  }
  

Just make sure you’re using a relatively recent version of Bunifu Framework, as older releases might have minor differences in property names or method exposure.
