Form1.cs

devexpress中 xtratabbedmdimanager和xtratabpage区别是什么？

常用：

1.TextEditor(barEditItem)取文本

string editValue = barEditItem1.EditValue.ToString(); //错误，返回null

string editValue = ((DevExpress.XtraEditors.TextEdit)barEditItem).EditValue.ToString(); //正确，返回文本框内容

2.ComboBoxEdit(barEditItem)添加Item

string item = "comboboxItem1";
((DevExpress.XtraEditors.Repository.RepositoryItemComboBox)this.barEditItem.Edit).Items.Add(item);

3.ComboBoxEdit(barEditItem)取文本

string itemValue = this.barEditItem.EditValue.ToString();
