Locking/checking out

Question

Hi,

I have an application which controls schedules....
I need locking/checking out logic on these schedules (people schedules).
Does anyone know of any C# components or .Net components that could help in doing this?

I dont want to have these locks in the database itself, I want this to reside in the application/business logic layer.

Thanks in advance,

Person.

You can use cookies if you don't want to store any data in database
Here's just a sample code to enable and disable a textbox, you can modify it to lock your schedule. Though this won't reside anywhere within the application but be a client side setting.

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.Cookies["State"].Value == "Locked")
        {
            TextBox1.Enabled = false;
        }
        else if (Request.Cookies["State"].Value == "Unlock")
        {
            TextBox1.Enabled = true;
        }

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        TextBox1.Enabled = false;
        Response.Cookies["State"].Value = "Locked";
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        TextBox1.Enabled = true;
        Response.Cookies["State"].Value = "Unlock";
    }

Hope this helps
