I found a solution. Steps as follows:
a. Created config file "MediaBrowser.config" and added into folder App_Config/Include (configuration xml below):
<configuration xmlns:patch= "http://www.sitecore.net/xmlconfig/">
<sitecore>
<commands>
<command name="example:MediaBrowser" type="SitecoreTraining.HelperClasses.MediaBrowser,SitecoreTraining" />
</commands>
</sitecore>
</configuration>
b. In my ascx control markup added the following to open the media browser:
<A class="scChromeCommand" title="Open Media Browser" onclick="javascript:Sitecore.PageModes.ChromeManager.postRequest('example:MediaBrowser(id=<%# Sitecore.Context.Item.ID.ToString() %>)',null,false)" href="#"><IMG alt="Open Media Browser" src="http://localhost:2438/temp/IconCache/applications/16x16/photo_scenery.png" width="16" height="16" /></A>
c. Created a MediaBrowser class that inherits the sitecore Command class with the following main methods used:
public override void Execute(CommandContext context)
{
Item item = context.Items.Length == 0 ? Context.Item : context.Items[0];
contextItem = item;
var parameters = new NameValueCollection();
wizardPipeline = Context.ClientPage.Start(this, "Run", parameters);
}
protected virtual void Run(ClientPipelineArgs args)
{
Database masterDb = Factory .GetDatabase("master");
if (args.IsPostBack)
{
var itemID = args.Result;
}
else
{
UrlString url = new UrlString (UIUtil .GetUri("control:Sitecore.Shell.Applications.Media.MediaBrowser" ));
Item folderItem = masterDb.GetItem("/sitecore/media library/Images" );
url["ro" ] = folderItem.Uri.ToString();
SheerResponse.ShowModalDialog(url.ToString(), true );
args.WaitForPostBack(true );
}
}
