C # How to define let PropertyGrid control display [...] button, and then click the drop-down box to display the custom control edit property values

For detailed usage of the PropertyGrid control, please refer to the literature:

1. C # PropertyGrid Control application Experience

2. C # Custom PropertyGrid properties

First define a control to be displayed in the drop-down box:

usingSystem; usingSystem.Windows.Forms; namespaceSimon.WinForms.Examples.PropertyGrid { Public classEditorcontrol:usercontrol { PublicEditorcontrol () { This. Label1 =NewSystem.Windows.Forms.Label ();  This. Label1. AutoSize =true;  This. Label1. Location =NewSystem.Drawing.Point ( +, -);  This. Label1. Name ="Label1";  This. Label1. Size =NewSystem.Drawing.Size ( A, A);  This. Label1. TabIndex =0;  This. Label1. Text ="Name:";  This. ComboBox1 =NewSystem.Windows.Forms.ComboBox ();  This. combobox1.formattingenabled =true;  This. ComboBox1.Items.AddRange (New Object[] {              "Name one",              "name Two",              "name three",              "name Four"});  This. combobox1.location =NewSystem.Drawing.Point ( About, +);  This. Combobox1.name ="ComboBox1";  This. combobox1.size =NewSystem.Drawing.Size (133, -);  This. Combobox1.tabindex =2;  This. combobox1.selectedindexchanged + =NewSystem.EventHandler ( This. combobox1_selectedindexchanged);  This.              SuspendLayout ();  This. Autoscaledimensions =NewSystem.Drawing.SizeF (6F, 12F);  This. AutoScaleMode =System.Windows.Forms.AutoScaleMode.Font;  This. Controls.Add ( This. ComboBox1);  This. Controls.Add ( This. Label1);  This. Name ="Editorcontrol";  This. Size =NewSystem.Drawing.Size ( About, -);  This. ResumeLayout (false);  This.          PerformLayout (); }            PrivateLabel Label1; PrivateComboBox ComboBox1;  Public stringresult =""; Private voidComboBox1_SelectedIndexChanged (Objectsender, EventArgs e) {Result=comboBox1.SelectedItem.ToString (); }      }  }  

Inherit a custom attribute edit manager class from System.Drawing.Design.UITypeEditor, as follows:

usingSystem.Drawing.Design; usingSystem.Windows.Forms.Design; namespaceSimon.WinForms.Examples.PropertyGrid { Public classEditor:uitypeeditor { Public OverrideUitypeeditoreditstyle GetEditStyle (System.ComponentModel.ITypeDescriptorContext context) {//when editing property values, display on the right ... More Buttons            returnUitypeeditoreditstyle.modal; }             Public Override ObjectEditValue (System.ComponentModel.ITypeDescriptorContext context, System.IServiceProvider provider,Objectvalue) {              varEdsvc = provider. GetService (typeof(IWindowsFormsEditorService)) asIWindowsFormsEditorService; if(Edsvc! =NULL)              {                  varPopedcontrol =NewEditorcontrol (); //and ShowDialog this way, you can pop a form to edit it.Edsvc.dropdowncontrol (Popedcontrol); Value=Popedcontrol.result; }              return Base.          EditValue (context, provider, value); }      }  }  

Defines a type that uses the PropertyGrid display property.

usingSystem.ComponentModel; namespaceSimon.WinForms.Examples.PropertyGrid { Public classShowedclass {[DisplayName ("name")] [Editor (typeof(Editor),typeof(System.Drawing.Design.UITypeEditor))] Public stringName {Get;Set; } [Editor (typeof(Editor),typeof(System.Drawing.Design.UITypeEditor))] Public stringDescription {Get;Set; } }  }  

Put PropertyGrid on the form, then instantiate your class and let PropertyGrid display the settings to see the effect.

New Showedclass () {name=" I have no name "};
