Answer 1

您需要使用State Management技术来实现此目的。我使用Session来演示。

在您拥有Submit按钮的页面上，您需要创建property，如下所示：

public string ButtonTextValue  
{
    get 
    {
        if (Session["ButtonValue"] == null)
            Session["ButtonValue"] = "Submit";

            return Convert.ToString(Session["ButtonValue"]); 
    }
    set
    {
            Session["ButtonValue"] = value;
    }
}

在同一页面的pageload上，您需要执行此操作：

protected void Page_Load(object sender, EventArgs e)  
{
    if (!IsPostBack)
    {
        YourButton.Text = ButtonTextValue;
    }
}

在第二页上你需要这样做：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "cmdBind")
    {
        LinkButton lb = (LinkButton)e.CommandSource;
        Session["ButtonValue"] = "Update";
        Response.Redirect("Form.aspx?ID=" + lb.Text + "");              
    }
}
