How to make a video slide and images with asp.net?

I need to make a slide video and images with asp.net, SlideExtender only works with pictures, the only option left is to make conditional updatepanel with a timer but I ran out of ideas, please some other ideas:

HTML Code:

<asp:ScriptManager ID="ScriptManager1" runat="server">asp:ScriptManager>
<div>
<asp:Timer ID="SlideShowTimer" runat="server" Interval="5000" OnTick="SlideShowTimer_Tick">asp:Timer>
<asp:UpdatePanel ID="SlideShowUpdPnl" runat="server" UpdateMode="Always">
<ContentTemplate>
<div id="DivSlide">
<img id="SlideShowImage1" src="images/logo11.png" runat="server" alt="Sanmina-SCI" visible="true" />
<video runat="server" id="SlideShoVideo" src="Uploads/Avideo1.mp4" controls="controls" autoplay="autoplay" visible="true"/>
<asp:Label ID="LblTitleSlideShow" runat="server" Text="">asp:Label>
div>
ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="SlideShowTimer" EventName="Tick" />
Triggers>
asp:UpdatePanel>
div>

Code Behind:

protected void SlideShowTimer_Tick(object sender, EventArgs e)
{
DateTime later = DateTime.Now.AddSeconds(.5);
while (DateTime.Now < later)
{
LblTitleSlideShow.Text = "Time Later : " + later;
}
this.SlideShowImage1.Src = RandomImageName();
this.LblTitleSlideShow.Text += this.SlideShowImage1.Src.ToString();
}
private string RandomImageName()
{
Random rand = new Random();
int RandomInt = rand.Next(0, 5);
string url = null;
switch (RandomInt)
{
case 0:
url = "../Uploads/Jellyfish.jpg";
break;
case 1:
url = "../Uploads/Lighthouse.jpg";
break;
case 2:
url = "../Uploads/sanmina-logo.png";
break;
case 3:
url = "../Uploads/Tulips.jpg";
break;
case 4:
url = "../Uploads/Koala.jpg";
break;
case 5:
url = "../Uploads/Penguins.jpg";
break;
default:
url = "../Uploads/123.png";
break;
}
return url;
}
