Without seeing the code it is very hard to say. From the information you have provided I would say that you need to leave the CommandName attribute on your Update button in the EditItemTemplate i.e.

<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" CommandName="Update" Text="Update" />

I would add the following event to your FormView that will execute when the record has been updated:

<asp:FormView ID="FormView1" runat="server" OnItemUpdated="FormView1_ItemUpdated"...

In your code behind for the FormView you should have the following:

protected void FormView1_ItemUpdated(object sender, System.Web.UI.WebControls.FormViewUpdatedEventArgs e)
{
    if (e.Exception == null && e.AffectedRows > 0)
    {
        Response.Redirect("manage-darkhast-maghale.aspx");
    }
}
