Display mediaFolderIds in a usercontrol
I found this nice razorscript that looks in after a specific folder (1132 ) in the Media Libary and gives me the names and Ids of its Children... the script works as it's intended - however it's rather dirty and straight forward... - my point is that I need to do the very same in a usercontrol using a dynamic feed asp.net:DropDownList in order to get the SelecdedIndex... - I've NO clue hov to write something simular in a usercontrol
```
@inherits umbraco.MacroEngines.DynamicNodeContext
@using umbraco.MacroEngines;
@using umbraco.cms.businesslogic.media;

@{
    var folderId = 1132;
    var media = Model.MediaById(folderId);
    var folders = media.Children;
    <form method="post">
        <select id="folderId" name="folderId" onchange="window.location.href = 'http://@Request.Url.Host/galleri/' + this.form.folderId.options[this.form.folderId.selectedIndex].value">
        @foreach(var item in folders)
        {
            <option value="@item.Id">@item.Name</option>
        }
        </select>
    </form>
}
```
It does'ne nessecary need to redirect though - it's just a feature... :-)

***Update***

After a few (lots of) Googlesearches I finally succeded in creating above macroscript as a usercontrol... - the final resault looks as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using umbraco.cms.businesslogic.media;

public partial class usercontrols_galleryTeaser : System.Web.UI.UserControl
{
    private int _pathTo;
    public int PathTo
    {
        get { return _pathTo; }
        set { _pathTo = value; }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            int mediaId = PathTo;
            Media node = new Media(mediaId);
            var childrenNodes = node.Children;

            folderid.DataSource = childrenNodes;
            folderid.DataValueField = "Id";
            folderid.DataTextField = "Text";
            folderid.DataBind();          
        }
    }

    protected void folderid_SelectedIndexChanged(object sender, EventArgs e)
    {
        Response.Redirect("/gallery/" + folderid.SelectedValue);
    }
}

Feel free to use anytime you whant... :-)
