embedding flash in server control

yussi ariefiyono — Mon, 29 Jun 2009 14:10:00 +0000

Problem:

When you got your website (aspx website), especially when you already put url rewriting, you want to embed flash ( doesnt matter if its swf or flv)
You need to have relative path, starting with ("~/" ) in the url.

Solution:
you can put the code in your server control, so it will be easier to integrate

FlashPlayer.ascx




    ' quality="high" bgcolor="#ffffff" width="745" height="181" name="header" align="middle" allowScriptAccess="sameDomain" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer_nl" />

and in the FlashPlayer.ascx.cs

protected void Page_Load(object sender, EventArgs e)
{

        Literal1.Text = Page.ResolveUrl("~/yourpath");
        Literal2.Text = Page.ResolveUrl("~/yourpath");
   }

and you will got flash playing! enjoy ^_^

================================

thank to Marc Neeft, hereby his input :

it would be even more powerful when you add the movieUrl, width and height as properties of the usercontrol:

private string movieUrl = String.empty;

private int movieWidth = 0;

private int movieHeight = 0;

protected void Page_Load(object sender, EventArgs e)

{

// todo: check if url, width and height are set, if not, throw exception

Literal1.Text = Page.ResolveUrl(movieUrl);

Literal2.Text = Page.ResolveUrl(movieUrl);

Literal3.Text = movieWidth;

Literal4.Text = movieHeight;

}

public string MovieUrl

{

get { return movieUrl; }

set { movieUrl = value; }

}

public string MovieWidth

{

get { return movieWidth; }

set { movieWidth = value; }

}

public int MovieHeight

{

get { return movieHeight; }

set { movieHeight = value; }

}

Of course you need to add the 2 extra literals and the errorchecking yourself but you get the general idea.

/movie.flv
" MovieWidth="300" MovieHeight="150" />

yussi ariefiyono — Tue, 09 Jun 2009 17:28:00 +0000

Putting repeater inside repeater and take ID of parent repeater to bind the datasourse.

Solution:
hereby the example of code:

in .aspx
    onitemdatabound="Repeater2_ItemDataBound">




            ()

in .aspx cs

private DataTable getDataTableforRepeater2(int TagID)
    {
        SqlConnection conn = new SqlConnection();
        conn.ConnectionString = ConfigurationManager.ConnectionStrings["yourconnectionName"].ConnectionString;

        SqlCommand command = new SqlCommand();
        command.Connection = conn;
        command.CommandText = "sql command";
        DataTable t = new DataTable();
        SqlDataAdapter adapter = new SqlDataAdapter();

adapter.SelectCommand = command;
adapter.Fill(t);

        return t;
    }
    protected void Repeater2_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater Repeater1 = e.Item.FindControl("Repeater1") as Repeater;

int TagID = int.Parse(DataBinder.Eval(e.Item.DataItem, "TagID").ToString());

            if (TagID != null)
            {
                DataTable t = getDataTableforRepeater2(TagID);
                if (t.Rows.Count > 0)
                {
                    Repeater1.DataSource = t;
                    Repeater1.DataBind();
                }

LOL.. long huh

Solution:
put this code in your .cs page

//overwrite the SavePageStateToPersistenceMedium and LoadPageStateFromPersistenceMedium
protected override void SavePageStateToPersistenceMedium(object viewState)
{

    }

    protected override object LoadPageStateFromPersistenceMedium()
    {

        return null;

}

// Remove completely after rendering html code
protected override void Render(HtmlTextWriter output)
{

        System.Text.StringBuilder stringBuilder = new System.Text.StringBuilder();

        System.IO.StringWriter stringWriter = new System.IO.StringWriter(stringBuilder);

        HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);

        foreach (Control ctrl in this.Controls)

            ctrl.RenderControl(htmlWriter);

        String html = stringBuilder.Replace("/>", ">").ToString();

        int intViewStart = html.IndexOf("
        int intViewFinish = html.IndexOf(">", intViewStart) + 1;

        string strViewTag = html.Substring(intViewStart, intViewFinish – intViewStart);

        System.Diagnostics.Debug.WriteLine(strViewTag);

        html = html.Replace(strViewTag, "");

        output.Write(html);

}

and WALA! its gone!!

find value in repeater asp net

yussi ariefiyono — Mon, 04 May 2009 17:18:00 +0000

Problem:
find value in repeater

Solution:
write this code in itemdatabound on your repeater:

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Label title = e.Item.FindControl("Label1") as Label; // depend on what component you r searching for

          Response.Write(title.Text);   // just check
        }
    }
