我正在尝试根据我在 Ext.net 的代码隐藏中选择的单选按钮隐藏 ComboBox 和/或 DateFields
<Items>
<ext:Container ID="Container1" runat="server" Layout="ColumnLayout" Height="175" Width="418" >
<Items>
<ext:RadioGroup runat="server" ID="ChooseSpan" Selectable="true" ColumnsNumber="1" ColumnWidth="0.50" >
<Items>
<ext:Radio ID="RadioAll" runat="server" BoxLabel="Show All" InputValue="0" />
<ext:Radio ID="RadioMonth" runat="server" BoxLabel="Choose Date Range(By Month)" InputValue="1" />
<ext:Radio ID="RadioDate" runat="server" BoxLabel="Choose Date Range(By Dates)" InputValue="2" />
</Items>
</ext:RadioGroup>
<ext:Container ID="Container2" runat="server" Layout="RowLayout" Height="175" ColumnWidth="0.50" StyleSpec="margin-top:25px;">
<Items>
<ext:ComboBox runat="server" ID="MonthComboBox" Selectable="true" SelectedIndex="0" >
<Items>
<ext:ListItem Text="Any Month" Value="0" />
<ext:ListItem Text="January" Value="1" />
<ext:ListItem Text="February" Value="2" />
<ext:ListItem Text="March" Value="3" />
<ext:ListItem Text="April" Value="4" />
<ext:ListItem Text="May" Value="5" />
<ext:ListItem Text="June" Value="6" />
<ext:ListItem Text="July" Value="7" />
<ext:ListItem Text="August" Value="8" />
<ext:ListItem Text="September" Value="9" />
<ext:ListItem Text="October" Value="10" />
<ext:ListItem Text="November" Value="11" />
<ext:ListItem Text="December" Value="12" />
</Items>
</ext:ComboBox>
<ext:DateField
ID="StartDateField"
runat="server"
FieldLabel="Start"
Vtype="daterange"
AnchorHorizontal="100%"
EnableKeyEvents="true">
<CustomConfig>
<ext:ConfigItem Name="endDateField" Value="#{EndDateField}" Mode="Value" />
</CustomConfig>
<Listeners>
<%--<Select Handler="#{DirectMethods}.SubmitDate();" />--%>
</Listeners>
</ext:DateField>
<ext:DateField
ID="EndDateField"
runat="server"
Vtype="daterange"
FieldLabel="End"
AnchorHorizontal="100%"
EnableKeyEvents="true">
<CustomConfig>
<ext:ConfigItem Name="startDateField" Value="#{StartDateField}" Mode="Value" />
</CustomConfig>
<Listeners>
<%-- <Select Handler="#{DirectMethods}.SubmitDate();" />--%>
</Listeners>
</ext:DateField>
<ext:Button ID="Next" runat="server" Text="Next" MaxWidth="50" StyleSpec="margin-left:159px; margin-top:150;" >
</ext:Button>
</Items>
</ext:Container>
</Items>
</ext:Container>
</Items>
</ext:Panel>
</Items>
这是使用 C# 背后的代码：
[DirectMethod]
public void DateSelection()
{
if (ChooseSpan.CheckedItems[0].ID == "RadioAll")
{
MonthComboBox.Visible = false;
StartDateField.Visible = false;
EndDateField.Visible = false;
}
if (ChooseSpan.CheckedItems[0].ID == "RadioMonth")
{
MonthComboBox.Visible = true;
MonthComboBox.Show();
StartDateField.Visible = false;
EndDateField.Visible = false;
}
if (ChooseSpan.CheckedItems[0].ID == "RadioDate")
{
MonthComboBox.Visible = false;
StartDateField.Visible = true;
StartDateField.Show();
EndDateField.Visible = true;
EndDateField.Show();
}
}
我需要 RadioGroup 中的听众来接受这些选择吗？我如何让代码隐藏响应我的选择，并告诉它隐藏与否？
