下面的示例演示了如何把不同的内置编辑器指派到列,它们分别被用于显示模式和编辑模式。
假设一个网格列显示整数值,在显示模式中应该使用进度条来呈现数据。 在编辑模式中,单元格的取值必须通过一个微调编辑器来编辑。 要实现此任务,必须通过 GridColumn.ColumnEdit 属性,把一个 ProgressBar 内置编辑器指派作为列的默认编辑器。 此编辑器被用于在显示模式中呈现数据。 为了提供一个用作内置编辑的自定义编辑器,接管了 GridView.CustomRowCellEditForEditing 事件。
下面的插图举例说明了运行结果:

using DevExpress.XtraEditors.Repository; // In-place editors used in display and edit modes respectively. RepositoryItem editorForDisplay, editorForEditing; private void Form1_Load(object sender, EventArgs e) { // Initialize the editors and assign the default editor to a column. editorForDisplay = new RepositoryItemProgressBar(); editorForEditing = new RepositoryItemSpinEdit(); gridView1.GridControl.RepositoryItems.AddRange( new RepositoryItem[] { editorForDisplay, editorForEditing }); gridView1.Columns["Quantity"].ColumnEdit = editorForDisplay; } // Provide the editor for in-place editing. private void gridView1_CustomRowCellEditForEditing(object sender, CustomRowCellEditEventArgs e) { if (e.Column.FieldName == "Quantity") e.RepositoryItem = editorForEditing; } |
