Repository files navigation

This example demonstrates how to implement a UI Type Editor (FilteredFileNameEditor) and use it within the PropertyGridControl.

1. Create aFilteredFileNameEditor class and implement theUITypeEditor interface:

   internalclassFilteredFileNameEditor:UITypeEditor{privateOpenFileDialogofd=newOpenFileDialog();publicoverrideUITypeEditorEditStyleGetEditStyle(ITypeDescriptorContextcontext){returnUITypeEditorEditStyle.Modal;}publicoverrideobjectEditValue(ITypeDescriptorContextcontext,IServiceProviderprovider,objectvalue){ofd.FileName=value.ToString();ofd.Filter="Text File|*.txt|All Files|*.*";if(ofd.ShowDialog()==DialogResult.OK){returnofd.FileName;}returnbase.EditValue(context,provider,value);}}

2. Apply theSystem.ComponentModel.Editor attribute as follows:

   publicclassFile{[System.ComponentModel.Editor(typeof(UIEditors.FilteredFileNameEditor),typeof(System.Drawing.Design.UITypeEditor))]publicstringPath{get;set;}publicstringPath2{get;set;}}

3. Assign a ButtonEdit to a cell as shown in the Assigning Editors to Editor Rows topic.

   privatevoidForm1_Shown(objectsender,EventArgse){RepositoryItemButtonEditedit=newRepositoryItemButtonEdit();edit.ButtonClick+=edit_ButtonClick;(this.propertyGridControl1.Rows[0]asCategoryRow).ChildRows["rowPath2"].Properties.RowEdit=edit;}

4. Handle the Button Editor's ButtonClick event.

   voidedit_ButtonClick(objectsender,DevExpress.XtraEditors.Controls.ButtonPressedEventArgse){this.openFileDialog1.ShowDialog();}
