使用其他条件启用/禁用基于Radiobuttonlist的Asp.net控件

问题描述:

亲爱的朋友们,



我正在使用Asp.net,c#,SqlServer 2005.



我有两个Textboxes FromDate和ToDate,我有两个Dropdwonlist列表,包括Month&年。



我的网页上有Radiobuttonlist,在这里我有两个带启用选项的项目。



当我选择一个选项启用时,它应该启用两个日期文本框和DISABLE两个下拉列表。



当我选择第二个选项启用时,它应该启用两个下拉列表和DISABLE两个日期文本框。



所以请帮助我,



这是我的代码。此外,我为radiobuttonlist提供了AutoPostBack = true。

试试这段代码:

Try this code:
<asp:radiobuttonlist id="RadioButtonList1" runat="server" autopostback="true" xmlns:asp="#unknown">
        onselectedindexchanged="RadioButtonList1_SelectedIndexChanged">
<asp:listitem text="Enable Text"></asp:listitem>
<asp:listitem text="Enable DDL"></asp:listitem>
</asp:radiobuttonlist>
    

<asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown"></asp:textbox>
    
<asp:dropdownlist id="DropDownList1" runat="server" xmlns:asp="#unknown"></asp:dropdownlist>







protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (RadioButtonList1.SelectedItem.Text == "Enable Text") // Enable text box
        {
            TextBox1.Enabled = true; // this is a just an example, place your controls here.
            DropDownList1.Enabled = false;
        }
        else if (RadioButtonList1.SelectedItem.Text == "Enable DDL") // Enable Dropdown
        {
            TextBox1.Enabled = false;
            DropDownList1.Enabled = true;
        }
        else
        {
            TextBox1.Enabled = false;
            DropDownList1.Enabled = false;
        }
    }
