如果要将其合并到当前向导中,则需要手动处理ActiveStepChanged
事件,并使用向导历史记录来确定应加载哪个步骤。
这将让你访问过的最后一个步骤:
/// <summary>
/// Gets the last wizard step visited.
/// </summary>
/// <returns></returns>
private WizardStep GetLastStepVisited()
{
//initialize a wizard step and default it to null
WizardStep previousStep = null;
//get the wizard navigation history and set the previous step to the first item
var wizardHistoryList = (ArrayList)wzServiceOrder.GetHistory();
if (wizardHistoryList.Count > 0)
previousStep = (WizardStep)wizardHistoryList[0];
//return the previous step
return previousStep;
}
下面是一些逻辑,我写了,而以前这是类似于你想做什么:
/// <summary>
/// Navigates the wizard to the appropriate step depending on certain conditions.
/// </summary>
/// <param name="currentStep">The active wizard step.</param>
private void NavigateToNextStep(WizardStepBase currentStep)
{
//get the wizard navigation history and cast the collection as an array list
var wizardHistoryList = (ArrayList)wzServiceOrder.GetHistory();
if (wizardHistoryList.Count > 0)
{
var previousStep = wizardHistoryList[0] as WizardStep;
if (previousStep != null)
{
//determine which direction the wizard is moving so we can navigate to the correct step
var stepForward = wzServiceOrder.WizardSteps.IndexOf(previousStep) < wzServiceOrder.WizardSteps.IndexOf(currentStep);
if (currentStep == wsViewRecentWorkOrders)
{
//if there are no work orders for this site then skip the recent work orders step
if (grdWorkOrders.Items.Count == 0)
wzServiceOrder.MoveTo(stepForward ? wsServiceDetail : wsSiteInformation);
}
else if (currentStep == wsExtensionDates)
{
//if no work order is selected then bypass the extension setup step
if (grdWorkOrders.SelectedItems.Count == 0)
wzServiceOrder.MoveTo(stepForward ? wsServiceDetail : wsViewRecentWorkOrders);
}
else if (currentStep == wsSchedule)
{
//if a work order is selected then bypass the scheduling step
if (grdWorkOrders.SelectedItems.Count > 0)
wzServiceOrder.MoveTo(stepForward ? wsServicePreview : wsServiceDetail);
}
}
}
}
感谢您的回复。看起来像我必须手动处理所有事情。我'有点犹豫要做这个方法,因为对我来说,其余的步骤是和完整的,但只有这个简单的步骤,我必须改变和手动处理一切? – Reuben 2013-03-09 17:28:04
它不需要完全手动。上述方法仅用于*当*你需要分支时,否则就让它正常运行。我的例子看起来很复杂,因为该功能需要的所有分支。 – 2013-03-09 18:03:46
真的..谢谢你的回答.. – Reuben 2013-03-09 18:17:43
