一把umbraco用户控件：用户控件本身获取usercontrol.property.Id？ [英] Umbraco usercontrol: Get usercontrol.property.Id within the usercontrol itself?

问题描述

我遇到一些麻烦与一把umbraco用户控件..
我试图建立一个照相馆..我有上有一个mediapicker一个用户控件，并保存我想产生拾取文件夹中所有mediafiles的缩略图。到目前为止好..

i'm having some trouble with the umbraco usercontrol.. I'm trying to develop a Photo Gallery.. I have a usercontrol with a mediapicker on it, and on save i would like to generate thumbnails of all mediafiles in the picked folder. So far so good..

这可能是1号文件中包含的图片库属性的不止一个，因此，确定用于存储缩略图我必须做这样的事情的路径：

It is possible that 1 document contains more than one of the Photo Gallery properties, so to determine the path for storing the thumbnails i have to do something like this:

PhotoGalleryStorageFolder / {DocumentID} / {} UsercontrolPropertyId

'PhotoGalleryStorageFolder/{DocumentID}/{UsercontrolPropertyId}'

检索文档编号很简单：

_currentNodeId = int.Parse(Request.QueryString["id"]);

问题是我不知道的别名，我不想硬code在我的用户控件可以有它的多个实例。

The problem is that i do not know the alias and i dont want to hardcode it in my usercontrol as there can be more instances of it..

code：

    private Int32 _currentNodeId = -1;
    private Int32 _currentPhotoGalleryId = -1;
    private String _value = ""; // Holds MediaPickerValue;

    protected void Page_Load(object sender, EventArgs e)
    {
        initialize();
    }

    #region Initialize
    private void initialize()
    {
        _currentNodeId = int.Parse(Request.QueryString["id"]);

        /////// PROBLEM \\\\\\\\\
        _currentPhotoGalleryId = -1; // How to retrieve this?!?!
        \\\\\\\ PROBLEM /////////

        Document d = new Document(_currentNodeId);

        if (!Page.IsPostBack)
        {
            this.setMediaPickerValue(_value);
            this.setPrevMediaPickerValue(_value);
        }
        else
            _value = this.getMediaPickerValue();

        Response.Write("_currentNodeId: " + _currentNodeId.ToString() + "<br />");
        Response.Write("_value: " + _value + "<br />");
    }

    void Document_AfterSave(Document sender, umbraco.cms.businesslogic.SaveEventArgs e)
    {

    }

    #endregion

    #region MediaPickerValue
    private String getMediaPickerValue()
    {
        return mediaPicker.Value;
    }

    private void setMediaPickerValue(String value)
    {
        mediaPicker.Value = value;
    }

    private String getPrevMediaPickerValue()
    {
        return prevMediaPickerValue.Value;
    }

    private void setPrevMediaPickerValue(String value)
    {
        prevMediaPickerValue.Value = value;
    }
    #endregion

    #region OnSave
    private void onSave()
    {
        String currentValue = this.getMediaPickerValue();
        String prevValue = this.getPrevMediaPickerValue();

        if (currentValue != prevValue) HttpContext.Current.Response.Write("Hergenereer thumbs.<br />");
        else HttpContext.Current.Response.Write("Thumbs hoeven niet opnieuw te worden gegenereerd.<br />");

        this.setPrevMediaPickerValue(currentValue);
    }
    #endregion

    public object value
    {
        get
        {
            onSave();
            return this.getMediaPickerValue();
        }
        set
        {
            Response.Write("Set triggered<br />");
            String val = string.IsNullOrEmpty(value.ToString())  || value == null ? "" : value.ToString();
            _value = val;
        }
    }

任何帮助将是巨大的..日Thnx提前！

Any help on this would be great.. Thnx in advance!

推荐答案

我最终增加一个额外的文本框（仅管理员可见）到用户控件，所以开发人员现在可以定义一个子文件夹中图片集锦的每个实例。日Thnx反正所有帮助。

I ended up adding an extra textbox (only visible to admins) to the usercontrol, so the developer can now define a subfolder for each instance of the PhotoGallery. Thnx for all the help anyway.
