什么是PropertyGrid控件

什么是PropertyGrid控件?很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。

PropertyGrid是一個很強大的控件,使用該控件做屬性設置面板的一個好處就是你只需要專注于代碼而無需關注UI的呈現,PropertyGrid會默認根據變量類型選擇合適的控件顯示。但是這也帶來了一個問題,就是控件的使用變得不是特別靈活,主要表現在你無法根據你的需求很好的選擇控件,比如當你需要用Slider控件來設置int型變量時,PropertyGrid默認的模板選擇器是不支持的。網上找了許多資料基本都是介紹WinForm的實現方式,主要用到了IWindowFromService這個接口,并未找到合適的適合WPF的Demo,后來在參考了DEVExpress的官方Demo之后我做了一個基于WPF和DEV 16.2的PropertyGrid Demo,基本實現了上述功能。

為了實現這一點,需要自定義一個DataTemplateSeletor類,這也是本文的核心代碼。

1.創建一個CustomPropertyGrid自定義控件:

該控件使用的資源字典如下:

3.編寫一個可用于構建模板的屬性 CustomUIType:

using System;namespace PropertyGridDemo.PropertyGridControl
{public class CustomUIType
    {

    }public enum CustomUITypes
    {

            CustomUI = uiTypes;
            DataContextPropertyName = dataContextPropertyName;
        }
    }

4.編寫對應的DataContext類 TestPropertyGrid:

5.將以上的CustomPropertyGrid丟進容器中即可,這里我直接用Mainwindow來演示:

以上就是自定義PropertyGrid控件的實現代碼,本人只實現了簡單的Slider和ComboBoxEdit控件,實際上可以根據自己的需要仿照以上的方法擴展到其他控件,這個就看需求了。

個人感覺以上方案還是有所欠缺,主要是自定義控件的模板是由代碼生成的,如果可以直接從資源文件中讀取將會更加方便,不過本人嘗試了幾次并不能成功的實現數據的綁定,如果大家有什么好的解決方案歡迎在評論區留言,也歡迎大家在評論區進行討論。
