I have an application where i need to show 2 frames. the top frame shows 2 windows media players, one that shows the video of a lecture and the other shows the video of images for the same lecture. In the lower frame i want to show all the imagesassociated with the lecture, so that when the user clicks on one image the video chunk associated with that image is shown in the upper frame.
The video main file (that houses the 2 frames is as follows)
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
if (!IsPostBack)
{
string flcode = Request.QueryString["f"].ToString().Trim();
string cpcode = Request.QueryString["c"].ToString().Trim();//image code
string cpPath = Request.QueryString["p"].ToString().Trim();//image path
lblflcode.Text = flcode;
lblcpcode.Text = cpcode;
lblcpPath.Text = cpPath;
if (cpcode == "" || cpcode==string.Empty || cpcode==null && cpPath=="" || cpPath==string.Empty || cpPath== null)
{
GetTopFrame();
GetBottomFrame();
}
}
}
public string GetTopFrame()
{
string flcode = lblflcode.Text.ToString().Trim();
string cpcode="";
string cppath ="";
return "<frame name=\"top\" src=\"TopVideoMain.aspx?f="+flcode+"&c="+cpcode+"&p="+cppath+"\">";
}
public string GetBottomFrame()
{
string flcode = lblflcode.Text.ToString().Trim();
return "<frame name=\"top\" src=\"BottomVideoMain.aspx?f="+flcode+"\" >";

}I am able to see the top video frame and the bottom when the videomain page loads, but when i click on an image- The top frame video doesnt stop but a new windows media player get created in the bottom frame and all the images are lost.
I want the upper frame to start playing the video associated with the image selected.
Thank you in advance.
