It will display watermark text on image

Animation : Moving label text up/down continuously in asp.net

Animation using code


Here i am using updatepanel and timer to refresh page 

in .aspx


<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <Triggers>
    <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
    </Triggers>
        <ContentTemplate>
            <asp:Timer ID="Timer1" runat="server" Interval="1000">
            </asp:Timer>


            <asp:Label ID="Lblanimation" runat="server" Text="Move Text"></asp:Label>


        </ContentTemplate>
  </asp:UpdatePanel>


in .cs page

if (ViewState["hit"] == null)

        {

            top = 1;

            top1 = 0;

           

        }

        else

        {

                     

           top = Convert.ToInt32(ViewState["hit"]);

           top1 = Convert.ToInt32(ViewState["hit1"]);

          

            if (top > 300 || top1>300)

            {

                top = (int)ViewState["hit"] - 1;

                top1 = (int)ViewState["hit1"] + 1;

                if (top == 1)

                {

                    top1 = 0;

                    left =Convert.ToInt32(ViewState["left"]) + 10;

                }

            }

            else

            {

                top = (int)ViewState["hit"] + 1;

                top1 = (int)ViewState["hit1"] + 1;

            }

        }

        lx.Attributes.Add("style", "top:"+top+"px;position:absolute;left:100px");

        ViewState["hit"] = top;

        ViewState["hit1"] = top1;

      

I have used viewstate to store the value generated when page get refresh

Label text move up and down continuously in every page refresh.

I have fixed the position up to 300 pixel.
