我想在RadioButtonList的OnSelectedIndexChanged事件上显示/隐藏Div标签(其中包含其他asp.net控件)。当Div标签可见时,Div标签中的Asp.net控件不可见?
问题:当我显示Div标签时,Div标签中的控件不可见。见下面
.aspx页面中我的代码
<asp:RadioButtonList ID="rblTesting" runat="server" AutoPostBack="true" OnSelectedIndexChanged="rblTesting_SelectedIndexChanged">
<asp:ListItem Text="Show" Selected="True" Value="0"></asp:ListItem>
<asp:ListItem Text="Hide" Value="1"></asp:ListItem>
</asp:RadioButtonList>
<div id="divName" runat="server">
<asp:Label ID="lblFirstName" runat="server" Text="James"></asp:Label>
<asp:Label ID="lblLastName" runat="server" Text="Anderson"></asp:Label>
</div>
.aspx.cs
Protected Sub rblTesting_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
If rblTesting.SelectedIndex = 0 Then
divName.Visible = True
'lblFirstName and lblLastName labels are not visible?
Else
divName.Visible = False
End If
End Sub
我可以显示/隐藏选定的指数变化事件在div个人控制。但是,我的问题是为什么我的控件在Div可见时不可见。
