Method to reset members inside groupBox

Question

is there any method for groupBox to clear all properties of objects inside groupBox. for example clear all textboxes, deselect all checkboxes etc. and set them to default. o

Answer 1

You would have to make a function like this:

private void ClearControls(Control control)
{
    var textbox = control as TextBox;
    if (textbox != null)
        textbox.Text = string.Empty;

    var dropDownList = control as DropDownList;
    if (dropDownList != null)
        dropDownList.SelectedIndex = 0;

    // And add any other controls
    // ...

    foreach( Control childControl in control.Controls )
    {
        ClearControl( childControl );
    }
}

Just call it like this:

ClearControls(this);

This will work recursively, so if you have any panels, for example, with their own set of controls to clear, this will clear those too.
