通过GetLimitedWebPartManager将参数传递给Web部件的特定实例

Question

我将参数从文本框传递给webpart，为一个可个性化的webpart具有更好的UI体验，在这种情况下采用Twitter Feed的形式。

问题我的问题是在用户网站上有多个实例的情况下，单击事件设置参数无法判断哪个WebPart正在进行呼叫。

我可以通过eventargs传递一些参数到getLimitedWebpartManager，它标识WebPart的唯一实例吗？

protected void setTwitterName_Click(object sender, EventArgs e)
{
    string Name = TwitterHandle.Text.Trim();

    if (!String.IsNullOrEmpty(Name))
    {
        using (var webPartManager = SPContext.Current.Web.GetLimitedWebPartManager("default.aspx",PersonalizationScope.User))
        {
            try
            {
                foreach (var twitterWebPart in webPartManager.WebParts.Cast<WebPart>().Where(webPart => webPart.Title == "Twitter").Cast<Twitter>())
                {
                    twitterWebPart.Name = Name;
                    webPartManager.SaveChanges(twitterWebPart);
                    PropertiesWebPart.Name = Name;
                    DisplayTweets();
                }
            }
            catch
            {
            }
        }
    }
}

Casting the control to its type, and then getting the ID of the BindingContainer, which is the WebPart, allows me to match that parameter to the ID of the Web Part being called.

    protected void setTwitterName_Click(object sender, EventArgs e)
    {
        string Name = TwitterHandle.Text.Trim();
        var x = (Button)sender;
        var WebPartID = x.BindingContainer.ID;

        if (!String.IsNullOrEmpty(Name))
        {
            using (var webPartManager = SPContext.Current.Web.GetLimitedWebPartManager("default.aspx",PersonalizationScope.User))
            {
                try
                {
                    foreach (var twitterWebPart in webPartManager.WebParts.Cast<WebPart>().Where(webPart => webPart.Title == "Twitter").Cast<Twitter>())
                    {
                        if(twitterWebPart.ID == WebPartID)
                        {
                            twitterWebPart.Name = Name;
                            webPartManager.SaveChanges(twitterWebPart);
                            PropertiesWebPart.Name = Name;
                            DisplayTweets();
                        }

                    }
                }
                catch
                {
                }
            }
        }
    }
}
