Allow your visitors to play YouTube videos on your site, brings your visitors closer to you in a way that is not typical of most websites.

Part 1:
Create a New webpage and name it: Youtube.aspx.
Create a Form with a text field and a Submit button.
Set the Method of the form to [POST] and the action, set to the same page we are on.

<form runat="server"> <label for="">YouTube ID</label> <asp:TextBox ID="YouTube" runat="server"></asp:TextBox> <asp:Label ID="IDLabel" runat="server" Text="Label"></asp:Label> <asp:Button id="YTBut" runat="server" Text="Play YouTube Video" OnClick="YTBut_Click1" /> </form>

Part 2:
Using an [IF STATEMENT] allows us to have the content on the same page and only show it when the visitor supplies a YouTube video ID.
Example: C-FGs18RCwk
And the Submit Button has been fired, with the Value of [Play YouTube Video]

<%// Create our variable String strYouTube = YouTube.Text; String UTube; // Next we call our variable and query it against the value of the input if (strYouTube != null && strYouTube != string.Empty) { UTube = strYouTube.Trim(); UTube = UTube.Replace("\'", "\'"); %>

Part 3:
The YouTube Object Properties.
The Video will be displayed here.
You can change the values of the width and height to the following.

width="560" height="315"
width="640" height="360"
width="853" height="480"
width="1280" height="720"
Going Higher than this can make some visitors' pages too big for their monitor.

<object width="425" height="344"> <param name="movie" value="https://www.youtube.com/v/<%=UTube%>&hl=en_US&fs=1&"></param> <param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param> <embed src="https://www.youtube.com/v/<%=UTube%>&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed> </object> <%}%>
