Clicking automatically the result serached by textbox cganged event

Yes, it's possible to automatically transfer the searched value from a TextBox to other textboxes by triggering an event when the text in the TextBox changes.

public MainForm()
{
    InitializeComponent();

    // Attach the TextChanged event handler to the search TextBox
    searchTextBox.TextChanged += SearchTextBox_TextChanged;
}

private void SearchTextBox_TextChanged(object sender, EventArgs e)
{
    string searchedValue = searchTextBox.Text;

    textbox1.Text = searchedValue;
    textbox2.Text = searchedValue;
}
