Problem with textbox responding to the same mousedown event

miracle2121

It's about the previous bunch of textboxes responding to the same mousedown event.

What I change in mousedown is the value of the current textbox. How do I pass parameters? ? ?

Set a variable, give the content to the variable before changing

I post the code. .
Definition of 2 textbox mousedown events
this.a1.MouseDown += new System.Windows.Forms.MouseEventHandler(this.textbox_MouseDown);
this.a2.MouseDown += new System.Windows.Forms.MouseEventHandler(this.textbox_MouseDown); use the same event
The event code is as follows
private void textbox_MouseDown(object sender,System.Windows.Forms.MouseEventArgs e)
{if(a1.Text=="")
                                      {
a1.Text="1";}
}
You should know this when you see this. . I want to change a2.text instead of a1.text when I click a2. How can I modify the code?

private void textbox_MouseDown(object sender,System.Windows.Forms.MouseEventArgs e)
{
TextBox temp = (TextBox)sender;
temp.Text = "1";
}
