嗨...

在aspx中 ：

Hi...
In aspx:

<asp:Label ID="lbltxt" runat="server" Text="Select Video file :" ForeColor="Brown" style="font-weight: 700"></asp:Label>

<asp:dropdownlist id="ddlvideo" runat="server" height="25px" appenddatabounditems="true" forecolor="DarkOliveGreen" onselectedindexchanged="DropDownList1_SelectedIndexChanged" width="170px" style="font-weight: 700" autopostback="True" xmlns:asp="#unknown"></asp:dropdownlist>

<asp:literal id="Literal1" runat="server" xmlns:asp="#unknown"></asp:literal>

在aspx.cs中：

In aspx.cs:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                con = new MySqlConnection(cs);
                con.Open();
                //Query to insert images path and name into database
                cmd1 = new MySqlCommand("select * from Videos", con);
                cmd1.ExecuteNonQuery();
                da = new MySqlDataAdapter(cmd1);
                DataSet ds = new DataSet();
                da.Fill(ds);
                con.Close();

                ddlvideo.DataSource = ds;
                ddlvideo.Items.Add("--- Select Video File ---");
                ddlvideo.DataValueField = "VideoNo";
                ddlvideo.DataTextField = "VideoName";
                ddlvideo.DataBind();
            }
        }

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
            string surl = "Videos/" + ddlvideo.SelectedItem.Text;
            if (surl == "Videos/" + "--- Select Video File ---")
            {
                ddllbl.ForeColor = Color.Red;
                ddllbl.Font.Bold = true;
                ddllbl.Text = "Pls Select Video File ";
                Literal1.Visible = false;
            }
            else
            {
                bool isfullsize = false;
                this.Literal1.Text = this.getvideo(surl, isfullsize);
            }
        }

        private string getvideo(string surl, bool isfullsize)
        {

            string sobj = "";
            surl = surl + "";
            surl = surl.Trim();
            if (surl.Length > 0)
            {

            }
            else
            {
                throw new System.ArgumentNullException("surl");
            }
            sobj = sobj + "<object classid='clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6' id='Player1' height='379' width='500' standby='Please wait loading file...'>";
            sobj = sobj + "<param name='url' value='" + surl + "' />";
            sobj = sobj + "<param name='src' value='" + surl + "' />";
            sobj = sobj + "<param name='uimode' value='full' />";
            sobj = sobj + "<param name='AutoStart' value='true' />";
            sobj = sobj + "<param name='ShowControls' value='1' />";
            sobj = sobj + "<param name='ShowStatusBar' value='1' />";
            sobj = sobj + "<param name='ShowDisplay' value='1' />";
            sobj = sobj + "<param name='stretchToFit' value='1' />";
            sobj = sobj + "<param name='enablecontextmenu' value='true' />";
            sobj = sobj + "<param name='fullscreen' value='" + isfullsize.ToString() + "' />";
            //sobj = sobj + "<embed type='application/x-mplayer2' pluginspage='http://www.microsoft.com/Windows/Downloads/Contents/MediaPlayer/' width='624' height='379' src='surl' filename='surl' autostart='1' showcontrols='1' showstatusbar='1' showdisplay='1'></embed>";
            sobj = sobj + "</object>";

            return sobj;
        }

谢谢你。
