隐藏asp.net向导上的按钮

Question

网络向导，我试图在某些情况下隐藏下一个按钮。我的问题是，我似乎无法使用向导FindControl（“”）完成按钮，它总是返回null

Answer 1

要使alejandrobog工作，你必须转换为StepNavigation Template

<StepNavigationTemplate>
    <asp:Button ID="StepPreviousButton" runat="server" CausesValidation="False" CommandName="MovePrevious">Previous</asp:Button>
    <asp:Button ID="StepNextButton" runat="server" CommandName="MoveNext">Next</asp:Button>
</StepNavigationTemplate>

然后FindControl工作

Button btnPre = (Button)Wizard1.FindControl("StepNavigationTemplateContainerID$StepPreviousButton");
btnPre.Visible = false;
Button btnNext = (Button)Wizard1.FindControl("StepNavigationTemplateContainerID$StepNextButton");
btnNext.Visible = false;

Answer 2

我最近发现此问题，您需要在控件ID之前添加StepNavigationTemplateContainerID $

Button finishButton = Wizard1.FindControl("StepNavigationTemplateContainerID$FinishButton") as Button;
