C# AJAXToolkit动态隐藏选项卡？

我知道如何隐藏选项卡：

MyTabContainerID.Tabs[1].Visible = false;

这很有效。我遇到的问题是更改由radioButtonList selectedIndexChanged事件的回发触发的选项卡的可见性

当页面到达我的selectedIndexChanged事件处理程序时，该选项卡已从ViewState加载Visible=True。我可以在selectedIndexChanged事件中将其全天更改为false，它不会隐藏已加载的选项卡b/c

ASPX

<asp:ListItem Text="Yes" Value="True" Selected="True"></asp:ListItem>
<asp:ListItem Text="No" Value="False"></asp:ListItem>

protected void Page_Init(object sender, EventArgs e)
{
    try
    {
        MyTabContainerID.Tabs[1].Visible = Tab1Visibility;
    }
    catch (Exception ex)
    {
        common.alert("Error in PageName.Page_Init.<br>ERROR=" + ex.Message);
    }
}
protected void rblMyRadioButtonList_SelectedIndexChanged(object sender, EventArgs e)
{
    try
    {       
        Tab1Visibility = Convert.ToBoolean(((RadioButtonList)sender).SelectedValue);
        MyTabContainerID.Tabs[1].Visible = Tab1Visibility;  //BY THE TIME THIS HAPPENS IT'S ALREADY ON THE PAGE WITH VISIBLE=TRUE                   
    }
    catch (Exception ex)
    {
        common.alert("Error in PageName.rblMyRadioButtonList_SelectedIndexChanged.<br>ERROR=" + ex.Message);
    }
}

    set { Session["ses_bTab1Visibility"] = value; }

        }
    function enableTab1() {
        $find('<%=MyTabContainer.ClientID%>').get_tabs()[1].set_enabled(true);
    }

想法？建议？

您应该能够在

rblMyRadioButtonList\u SelectedIndexChanged

方法中设置选项卡控件的可见性。即使此时已从ViewState加载选项卡控件的状态，仍可以覆盖它

我有一个类似的问题，就是无法设置可见性。我快疯了。解决方案是在容器（父级）控件中显式设置可见性。这将覆盖子控件的设置。这可能是你的问题吗

除此之外，照常做。

rblMyRadioButtonList上的断点\u选择的索引已更改

并监视值。另外-您可以手动强制在

页面_PreRender

上显示，该页面仍然位于下游

编辑

另一个可能影响它的因素是更新面板。如果radiobutton列表位于更新面板中，而选项卡位于其外部，则更新将无法工作，因为带有选项卡的页面部分将无法刷新

以下是我最后做的事情：

*.ASPX

<asp:RadioButtonList ID="rblMyRadioButtonList" runat="server" AutoPostBack="true" OnSelectedIndexChanged="rblMyRadioButtonList_SelectedIndexChanged">                                                        
<asp:ListItem Text="Yes" Value="True" Selected="True"></asp:ListItem>
<asp:ListItem Text="No" Value="False"></asp:ListItem>

protected void Page_Init(object sender, EventArgs e)
{
    try
    {
        MyTabContainerID.Tabs[1].Visible = Tab1Visibility;
    }
    catch (Exception ex)
    {
        common.alert("Error in PageName.Page_Init.<br>ERROR=" + ex.Message);
    }
}
protected void rblMyRadioButtonList_SelectedIndexChanged(object sender, EventArgs e)
{
    try
    {       
        Tab1Visibility = Convert.ToBoolean(((RadioButtonList)sender).SelectedValue);
        MyTabContainerID.Tabs[1].Visible = Tab1Visibility;  //BY THE TIME THIS HAPPENS IT'S ALREADY ON THE PAGE WITH VISIBLE=TRUE                   
    }
    catch (Exception ex)
    {
        common.alert("Error in PageName.rblMyRadioButtonList_SelectedIndexChanged.<br>ERROR=" + ex.Message);
    }
}

protected bool Tab1Visibility
{
    get { return (bool)Session["ses_bTab1Visibility"]; }
    set { Session["ses_bTab1Visibility"] = value; }
}

<script type="text/javascript">
    function disableTab1() {
            $find('<%=MyTabContainer.ClientID%>').get_tabs()[1].set_enabled(false);
        }
    function enableTab1() {
        $find('<%=MyTabContainer.ClientID%>').get_tabs()[1].set_enabled(true);
    }
</script>

<!--THESE RADIOBUTTONS LEVERAGE THE TAB CONTAINER'S CLIENTSIDE set_enabled METHOD
<asp:RadioButtonList ID="rblMyRadioButtonList" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow">
    <asp:ListItem Text="Yes" Value="True" Selected="True" onClick="enableTab1();"></asp:ListItem>

不仅在我的selectedIndexChanged事件中将选项卡可见性设置为False，而且根据您的建议，我在页面预渲染中再次将其设置为False。该选项卡在页面加载时仍然可见。如果我将选项卡的可见性设置为False！IsPostBack，这很有效。但是，当设置回发的可见性时，我没有得到任何乐趣。可能值得注意的是页面层次结构：页面>选项卡容器>选项卡面板>FormView>RadioButtonlistah…您的编辑有一定的意义…这很可能是问题所在…我还需要进一步研究。
