我正在根據數據庫中的某些條件從代碼隱藏創建嚮導控件。我需要從代碼中應用佈局模板。我檢查了MS示例,其全部基於設計時間,而不是在運行時。以編程方式設置嚮導佈局模板
請幫我設置asp.net嚮導控件的佈局模板。最好是一些代碼示例。
更新:
我想我應該已經有點更復雜。其實我沒有看到我從模板中添加的嚮導中的控件。這裏是我的示例代碼
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);
}
}
我在頁面init上這樣做。我沒有看到我在其中創建的控件。想知道這裏出了什麼問題。
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);
最後,我希望向導使用下面的佈局,但在代碼
<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>
