public class MyGridView : GridView
{
    protected GridViewRow _footerRow = null;

    public override GridViewRow FooterRow
    {
        get
        {
            if (_footerRow == null)
            {
                return base.FooterRow;
            }
            else
            {
                return _footerRow;
            }
        }
    }
    public MyGridView()
    {
    }

    protected override int CreateChildControls(System.Collections.IEnumerable dataSource, bool dataBinding)
    {
        ...


        ...
    }



    [System.ComponentModel.Category("Behavior")]
    [Themeable(true)]
    [System.ComponentModel.Bindable(System.ComponentModel.BindableSupport.No)]
    public bool ShowHeaderWhenEmpty
    {

        set
        {
            this.ViewState["ShowHeaderWhenEmpty"] = value;

We'd need to know something about what you wanted your GridView to support that isn't possible in the standard one.

我们需要了解您希望GridView支持的内容,这在标准版本中是不可能的。
