Hello

In my design.aspx page i am taking an object to display youtube link:Iam entering the youtube link in textbox and when i click the button i need to play that video.

<asp:TextBoxID="txt1"runat="server"Width="600px"></asp:TextBox>
<asp:ButtonID="btn1"runat="server"Text="youtube"Width="114px"onclick="btn1_Click"/
<objectwidth="480"height="385"><paramname="movies"value='<%# urllnk%>'/>
<paramname="allowFullScreen"value="true"/>
<paramname="allowscriptaccess"value="always"/>

in my code behind class

protectedvoid btn1_Click(object sender, EventArgs e)
{
string url = txt1.Text;
if (url.Contains("youtube.com"))
{
string urllnk = GetYouTubeID(url);
}
else
{
Response.Write("This URL is not a valid YOUTUBE video link because it does not contain youtube.com in it");
}
}
privatestring GetYouTubeID(string youTubeUrl)
{Match regexMatch = Regex.Match(youTubeUrl, "^[^v]+v=(.{11}).*",
RegexOptions.IgnoreCase);
if (regexMatch.Success)
{
return"http://www.youtube.com/v/" + regexMatch.Groups[1].Value +
"&hl=en&fs=1";
}
return youTubeUrl;
}

how to bind the textbox value to param and how to display the video

getting error:The name urllnk doennot exist in the current context

Hi,

the name urllnk indeed does not exist in the current context because you need to declare urllink either as a public property or protected variable with page scope.
Once you've done that you could use it as an inline expression.
