set tooltip text to textbox

Question

Picture:

I want my tooltip to show the text that is set in a textbox, how can I do this exactly? Yes I know the Tooltip property but textbox.Text does not work, I just want to show textbox text in tooltip (dynamic).

Thanks for your help

Answer 1

if you want to change the Tooltip each time the TextBoxText has changed you can put the SetToolTip() Function into the OnTextChanged() Callback.

ToolTip toolTip1 = new ToolTip();

public Form1() {
    InitializeComponent();
    toolTip1.ShowAlways = true;
    toolTip1.ToolTipTitle = "TextBox Text";
    toolTip1.SetToolTip(textBox1, textBox1.Text);
}

private void OnTextChanged(object sender, EventArgs e) {
    toolTip1.SetToolTip(textBox1, textBox1.Text);
}

To add the TextChanged Event you need to open the TextBoxs Property page, click on the Thunderbolt and add the Function Name to the TextChanged Row.
