Question

I have about 60 textboxes and it’s a mess when each one has its own code section. For some events actions are the same and for others there can be a dictionary with actions. Problem is I don’t know how to iterate through textboxes, get current textbox reference and run some methods which will change current textbox’s text.

UPD: What I’m trying to do is make all textboxes run AllTextboxesEnter method which will change their text according to textbox’s name, run AllTextboxesLeave method which will perform some action from action dictionary according to textbox’s name.

Answer 1

Assuming I understand the question correctly, here’s my answer to the interpretation of the question

private void Form1_Load(object sender, EventArgs e)
{
    foreach (TextBox tb in this.Controls.OfType<TextBox>())
    {
        tb.Enter += new EventHandler(textBoxAll_Enter);
        tb.Leave += new EventHandler(textBoxAll_Leave);
    }
}

private void textBoxAll_Enter(object sender, EventArgs e)
{
    ((TextBox)sender).Text = "textbox gained focus";
}

private void textBoxAll_Leave(object sender, EventArgs e)
{
    ((TextBox)sender).Text = "textbox lost focus";
}
