Spread for WinForms 提供的ComboBoxCellType单元格类型,为我们暴露了 ListControl 属性,通过该属性我们可以为 ComboBoxCellType 指定自定义的 ListBox 控件。
下面就演示以下如何设置自定义的ListBox控件,并为ListBox添加键盘事件,在窗体的Load事件中添加以下代码:
- private void Form1_Load(object sender, EventArgs e)
- {
- FarPoint.Win.Spread.CellType.ComboBoxCellType cmbocell = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
- ListBox list = new ListBox();
- list.Items.AddRange(new Object[] { "One", "Two", "Three" });
- list.KeyDown += new KeyEventHandler(list_KeyDown);
- cmbocell.ListControl = list;
- cmbocell.Items = (new String[] { "One", "Two", "Three" });
- fpSpread1.ActiveSheet.Columns[0].CellType = cmbocell;
- }
复制代码
指定ListBox的KeyDown事件:
- void list_KeyDown(object sender, KeyEventArgs e)
- {
- System.Diagnostics.Debug.WriteLine(e.KeyValue);
- }
复制代码
