आप संपत्ति ग्रिड के साथ उपयोग के लिए एक कस्टम संग्रह संपादक प्रपत्र कैसे बनाते हैं?

यह ब्रैंडन के सवाल का जवाब देता है। मैंने भी डिफ़ॉल्ट प्रॉपर्टीग्रिड संग्रह संपादक को वास्तव में प्रतिस्थापित करने के तरीके पर लंबी और कड़ी खोज की। नाथन का उत्तर अंतिम समाधान था। ब्रैंडन यहां बताया गया है कि मैं नाथन के समाधान का उपयोग करने और अपने स्वयं के संग्रह संपादक का उपयोग करने में सक्षम था।

using Swfd = System.Windows.Forms.Design;
using Scm = System.ComponentModel; 
using Sdd = System.Drawing.Design;
public class CustomCollectionModalEditor : Sdd.UITypeEditor
{
public override Sdd.UITypeEditorEditStyle GetEditStyle(Scm.ITypeDescriptorContext context)
{
    if (context == null || context.Instance == null)
    return base.GetEditStyle(context);

    return Sdd.UITypeEditorEditStyle.Modal;
}

public override object EditValue(Scm.ITypeDescriptorContext context, IServiceProvider provider, object value)
{
    Swfd.IWindowsFormsEditorService editorService;

    if (context == null || context.Instance == null || provider == null)
    return value;

    editorService = (Swfd.IWindowsFormsEditorService)provider.GetService(typeof(Swfd.IWindowsFormsEditorService));

    //CForm CollectionEditor = new CForm();
    //---  Replaced the Collection from this post with mine which requires an argument that passes the collection
    Ccne.CustomCollection editgcp = new Ccne.CustomCollection();  // Ccne.CustomCollection is my collection
    editgcp = MYGCPS;  // MYGCPS is the actual instance to be edited

    Gcp_Editor.GcpEditorMain CollectionEditor = new Gcp_Editor.GcpEditorMain(editgcp);  // call my editor 

    if (editorService.ShowDialog(CollectionEditor) == System.Windows.Forms.DialogResult.OK)
    {
    MYGCPS = CollectionEditor.ReturnValue1; // update current instance of the collection with the returned edited collection
    THISPG.Refresh();  // calls a method which refreshes the property grid
    return value; // the replaces the statment in the post >> CollectionEditor.Programmed;
    }
    //---
    return value;

    //return base.EditValue(context, provider, value);
}
}
