我需要知道这是否可能，我有一个向导，当我进入第5步时，我需要将按钮从"下一步"更改为"完成"按钮，因为向导的"完成"步骤没有显示步骤，我需要它显示，所以我想办法做一些事情，但我需要一个按钮在到达第5步后变为可见，但问题是它必须在activeStepChanged上完成（我认为）。

这是代码：

protected void wizard1_ActiveStepChanged ( object sender, EventArgs e ) {
    ((Button)(wizard1.FindControl("StepNavigationTemplate$btnNext"))).Visible = true;
    ((Button)(wizard1.FindControl("StepNavigationTemplate$btnFinish"))).Visible = false;
    switch(wizard1.ActiveStepIndex) {
        case 1:
            wizard1.MoveTo(WizardStep2);
            break;
        case 2:
            wizard1.MoveTo(WizardStep3);
            break;
        case 3:
            wizard1.MoveTo(WizardStep4);
            break;
        case 4:
            wizard1.MoveTo(WizardStep5);
            ((Button)(wizard1.FindControl("StartNavigationTemplateContainerID$btnNext"))).Visible = false;
            ((Button)(wizard1.FindControl("StartNavigationTemplateContainerID$btnFinish"))).Visible = true;
            break;
        case 5:
            wizard1.MoveTo(WizardStep6);
            break;
    }
}

这样做可能吗？因为当我运行代码时，它说按钮为空，我尝试了其他方法，比如：

protected void wizard1_ActiveStepChanged ( object sender, EventArgs e ) {
    Button btnNext = (Button)wizard1.FindControl("btnNext");
    Button btnFinish = (Button)wizard1.FindControl("btnFinish");
    btnNext.Visible = true;
    btnFinish.Visible = false;
    switch(wizard1.ActiveStepIndex) {
        case 1:
            wizard1.MoveTo(WizardStep2);
            break;
        case 2:
            wizard1.MoveTo(WizardStep3);
            break;
        case 3:
            wizard1.MoveTo(WizardStep4);
            break;
        case 4:
            wizard1.MoveTo(WizardStep5);
            btnNext.Visible = false;
            btnFinish.Visible = true;
            break;
        case 5:
            wizard1.MoveTo(WizardStep6);
            break;
    }
}

但它总是告诉我按钮为空，有什么方法可以在ActiveStepChanged上抓住按钮吗？如果没有，我有什么替代方案可以让它发挥作用？

这是按钮代码：

<StartNavigationTemplate>
    <asp:Button ID="StartNextButton" runat="server" CommandName="MoveNext" Text="SEGUINTE" CssClass="wizard-nav-buttons" ValidationGroup="valReg" CausesValidation="true" />
</StartNavigationTemplate>
<StepNavigationTemplate>
    <div style="display: table-cell;">
        <asp:Button ID="btnPrevious" runat="server" Text="ANTERIOR" CommandName="MovePrevious" CausesValidation="true" CssClass="wizard-nav-buttons prev" />
    </div>
    <div style="display: table-cell; padding-left: 10px;">
        <asp:Button ID="btnNext" runat="server" CommandName="MoveNext" Text="SEGUINTE" CausesValidation="true" CssClass="wizard-nav-buttons" />
    </div>
    <div style="display: table-cell; padding-left: 10px;">
        <asp:Button ID="btnFinish" runat="server" OnClick="wizard1_FinishButtonClick" Text="SUBMETER PROPOSTA" CssClass="wizard-nav-buttons submeterProposta" CausesValidation="true" Visible="false" />
    </div>
</StepNavigationTemplate>
<FinishNavigationTemplate></FinishNavigationTemplate>

到目前为止谢谢你。

我找到了解决方案，实际上它非常简单，因为我试图在ActiveStepIndex定义（预渲染）之前调用按钮，但找不到它（正常，因为它甚至没有创建），所以经过几次尝试和1个上午的搜索和测试，我试图将它放在交换机中的一个案例之后，它被找到了，因此，对于那些可能有这种困难的人来说，这里是功能代码：

protected void wizard1_ActiveStepChanged ( object sender, EventArgs e ) {
    Button btnNext , btnFinish;
    switch(wizard1.ActiveStepIndex) {
        case 1:
            btnNext = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnNext");
            btnFinish = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnFinish");
            btnNext.ValidationGroup = "valAutUniq";
            btnNext.Visible = true;
            btnFinish.Visible = false;
            wizard1.MoveTo(WizardStep2);
            break;
        case 2:
            btnNext = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnNext");
            btnFinish = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnFinish");
            btnNext.ValidationGroup = "valAutUniq";
            btnNext.Visible = true;
            btnFinish.Visible = false;
            wizard1.MoveTo(WizardStep3);
            break;
        case 3:
            btnNext = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnNext");
            btnFinish = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnFinish");
            btnNext.ValidationGroup = "valFormPag";
            btnNext.Visible = true;
            btnFinish.Visible = false;
            wizard1.MoveTo(WizardStep4);
            break;
        case 4:
            btnNext = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnNext");
            btnFinish = (Button)wizard1.FindControl("StepNavigationTemplateContainerID").FindControl("btnFinish");
            btnNext.ValidationGroup = null;
            btnNext.Visible = false;
            btnFinish.Visible = true;
            wizard1.MoveTo(WizardStep5);
            break;
    }
}
