Question

I have the following onclick event for a button. once this event is ftonired i want to disable the button. Can anyone help me to understand how to do it?

Here is the code i execute on buttonclick event.

protected void Button3_Click(object sender, EventArgs e)
{

    if (Session["login"] != null && Session["db"] != null)
    {

        digit b = new digit();
        String digitformed = b.formdigit(this.DropDownList1, this.TextBox1, this.TextBox2);

        chekcount c = new chekcount();
        int count = c.getmaxcountforjud_no(digitformed);
        int addtocount = count + 1;

        String name = Session["login"].ToString();
        String databs = Session["db"].ToString();
        String complex_name = name + databs;

        if (DropDownList2.SelectedItem.Text != "New")
        {
            update u = new update();
            u.update1(this.Editor1, digitformed, this.TextBox3, complex_name, name, this.DropDownList2);
            Response.Write(@"<script language='javascript'>alert('Updated')</script>");

        }
        else
        {
            save d = new save();
            d.dosave(this.Editor1, addtocount, digitformed, this.TextBox3, complex_name, name);
            Response.Write(@"<script language='javascript'>alert('Saved')</script>");

        }
    }
    else
    {
        Response.Redirect("log.aspx");
    }
}

Here is the Button which i want to disable.

<asp:Button ID="Button3" runat="server" Text="Save" onclick="Button3_Click" 
                    Visible="False" />
