我正在根据数据库中的某些条件从代码隐藏创建一个向导控件。我需要从代码中应用布局模板。我检查了 MS 示例,它全部基于设计时,而不是在运行时。
请帮助我设置 asp.net 向导控件的布局模板。最好是一些代码示例。
更新:
我想我应该更详细一点。实际上,我没有看到从模板添加的向导中的控件。这是我的示例代码
public class WizardTemplate:ITemplate
{
public void InstantiateIn(Control container)
{
PlaceHolder header = new PlaceHolder();
header.Controls.Add(new LiteralControl("I am from Header"));
header.ID = Wizard.HeaderPlaceholderId;
PlaceHolder displaySideBar = new PlaceHolder();
displaySideBar.Controls.Add(new LiteralControl("I am from displaySideBar"));
displaySideBar.ID = Wizard.SideBarPlaceholderId;
PlaceHolder wizardStep = new PlaceHolder();
wizardStep.Controls.Add(new LiteralControl("I am from wizard step"));
wizardStep.ID = Wizard.WizardStepPlaceholderId;
PlaceHolder navigation = new PlaceHolder();
navigation.ID = Wizard.NavigationPlaceholderId;
container.Controls.Add(header);
container.Controls.Add(displaySideBar);
container.Controls.Add(wizardStep);
container.Controls.Add(navigation);
}
}
我正在页面初始化上执行此操作。我没有看到我在其中创建的控件。想知道这里出了什么问题。
Wizard testWizard = new Wizard();
testWizard.LayoutTemplate = new WizardTemplate();
for (int i = 0; i < 4; i++)
{
WizardStep step = new WizardStep();
step.Title = "Step" + i.ToString();
step.ID = "Step" + i.ToString();
step.Controls.Add(new LiteralControl("<b> Step" + i.ToString() + "</b>"));
testWizard.WizardSteps.Add(step);
}
pnlRunTimeWizardContainer.Controls.Add(testWizard);
最终我希望向导使用下面的布局,但在代码中
<asp:Wizard ID="Wizard1" runat="server" EnableViewState="true">
<LayoutTemplate>
<div>
<asp:PlaceHolder ID="headerPlaceHolder" runat="server" />
</div>
<div style="float: right">
<asp:PlaceHolder ID="navigationPlaceHolder" runat="server" />
</div>
<div>
<asp:PlaceHolder ID="sideBarPlaceHolder" runat="server" />
</div>
<div>
<asp:PlaceHolder ID="WizardStepPlaceHolder" runat="server" />
</div>
</LayoutTemplate>
<WizardSteps>
</WizardSteps>
</asp:Wizard>
