有关AlterControl控件的简单应用

AlertControl控件首先是用来在页面上弹出提示框的。在DevExpress.XtraBars.Alerter这个命名空间下。如果用代码来生成altercontrol控件的话，例子如下：

如果我们在form窗体上直接拖一个控件过来，那么对于altercontrol控件的事件就很熟悉了；
private void alertControl1_ButtonDownChanged(object sender, AlertButtonDownChangedEventArgs e) {
if(e.ButtonName == "Flag")
((MailData)e.Info.Tag).Flag = e.Down ? 0 : 1;
if(e.ButtonName == "Read")
((MailData)e.Info.Tag).Read = e.Down ? 1 : 0;
}
private void alertControl1_ButtonClick(object sender, AlertButtonClickEventArgs e) {
MailData data = e.Info.Tag as MailData;
e.AlertForm.OwnerForm.Activate();//激活窗体
if(e.ButtonName == "Attachment") {
e.AlertForm.Close();//弹出窗体关闭
XtraMessageBox.Show(FindForm(), "Open attachment dialog.", string.Format("Mail From: {0}", data.From));
}
if(e.ButtonName == "Delete")
DeleteItem(e, data);
}
void OpenItem(MailData data) {
for(int i = 0; i < gridView1.RowCount; i++) {
if(data.Row.Equals(gridView1.GetDataRow(i))) {
gridView1.FocusedRowHandle = i;
break;
}
}
}
void DeleteItem(AlertClickEventArgs args, MailData data) {
args.AlertForm.Close();
try {
DataTable tbl = gridControl1.DataSource as DataTable;
tbl.Rows.Remove(data.Row);
gridView1.LayoutChanged();
}
catch { }
}
private void alertControl1_AlertClick(object sender, AlertClickEventArgs e) {
MailData data = e.Info.Tag as MailData;
OpenItem(data);
}
下面看下用代码直接生成的例子：
private IAppMain appMainCode;
private delegate void CloseAlert(AlertControl ac);
void createAlterControl()
{
AlertControl ac = new AlertControl();
ac.ShowPinButton = true;
ac.ShowCloseButton = true;
ac.AlertClick += new AlertClickEventHandler(alertControl1_AlertClick);
ac.FormLoad += alertControl1_FormLoad;
AlertInfo info = new AlertInfo("拉停提醒", alertinfo, null, null, equ.id);
ac.Show(appcontrol, info);
}
/// <summary>
/// 点击链接弹出页面
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void alertControl1_AlertClick(object sender, DevExpress.XtraBars.Alerter.AlertClickEventArgs e)
{
CreateAlertControl cr = new CreateAlertControl();
string menucode = GetxmlDoumentByMenuCode();//得到配置文件；
if (!String.IsNullOrEmpty(menucode))
{
appMainCode.OpenApp(cr, menucode);
}
else
{
MessageBox.Show("请配置xml文件中的拉停监控的菜单编号！");
}
}
/// <summary>
/// 窗体加载时锁定页面
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void alertControl1_FormLoad(object sender, AlertFormLoadEventArgs e)
{
e.Buttons[1].OnClick();//弹出页面只放出了锁定和关闭按钮。
}
/// <summary>
/// 弹出窗体关闭
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void alertControl1_FormClose(string equid)
{
lock (diclst)
{
if (diclst != null && diclst.Count > 0)
{
if (diclst.ContainsKey(equid))
{
AlertControl delete = new AlertControl();
delete = diclst[equid];
diclst.Remove(equid);
delete.AlertFormList[0].Invoke(new CloseAlert(AlertClose), delete);//此处由于程序运行时再辅助线程，所以需要通过Invoke回到主线程上去执行；
}
}
}
}
private void AlertClose(AlertControl ac)
{
ac.AlertFormList[0].Buttons[0].OnClick();
}
另一方面，如果我们新建个类，类中的数据需要在别的页面调用。我们就可以通过将类实例化去得到类中的属性；
public static CreateAlertControl Instance
{
get;
set;
}
在页面加载时赋值Instance = this;
在别的页面我们就可以通过CreateAlertControl.diclst去调用类中的属性；
