how to remove programmatically a label dragged from the toolbox?

Valerie Meunier

i dragged a label from the toolbox and i created programmatically another label:

private void button1_Click_1(object sender, EventArgs e)
{
Label lbl = new Label();
lbl.Text = "dynamic";
label1.Text = "toolbox"; // from toolbox
Controls.Add(lbl);
Controls.Clear();
}

I want to remove both labels from the form. When i run it, i don't see anything in the form, but when i go to view designer, the label 'lbl' is removed but the label 'label1' (from the toolbox) is still there. How can i remove it as well (i also tried with Controls.Remove(label1))?

Thanks

Accepted answer
var label = this.Controls.OfType().FirstOrDefault(l => l.Name == "label1");
if (label != null)
    Controls.Remove(label);

// OR

foreach (Control control in this.Controls)
{
    if (control.Name == "label1")
        control.Dispose();
}
By using above two code you can remove any control. But in your case its not remove permanently, its remove the control when you run your appication because its not created dynamically.

It is expected behavior,
creating a control dynamically===> there is no control but on run time controls will be created.

Deleting a control dynamically===> there are controls, but will remove on run time and will again come , then will again remove when you run the app.

so, deleting a control at run time will always temperorily remove the constrols.
