Answer 1

You need to use a State Management technique to implement this. I have used Session to demonstrate.
On your page where you have the Submit button you need to create a property like this:
public string ButtonTextValue
{
get
{
if (Session["ButtonValue"] == null)
Session["ButtonValue"] = "Submit";
return Convert.ToString(Session["ButtonValue"]);
}
set
{
Session["ButtonValue"] = value;
}
}
On pageload of the same page you need to do this:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
YourButton.Text = ButtonTextValue;
}
}
And on the second page you need to do this:
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 + "");
}
}
