Question

I have an asp.net web application. the listbox has a data source of one field. it has 10 items. i want the user to be able to add a comment for every (or for specific) items. so i would like a listbox or combobox with 2 fields. one field will be the list of items and the other field will be blank and will allow user input.

does such a control already exist? the solution can be c#, asp.net, jquery.

i understand that this can be done with gridview, but can you please tell me how i can make one field read only and the other field editable?

As per @Joshua Smith ‘s suggestion…

ASP.NET

<table>
       <tr>
           <td>
               <asp:ListBox ID="ListBox1" runat="server"></asp:ListBox>
           </td>
       </tr>
       <tr>
           <td>
               <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
           </td>
       </tr>
        <tr>
            <td>
                <asp:Button ID="Button1" Text="Submit" runat="server"></asp:Button>
            </td>
        </tr>
</table>

C#

        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            TextBox1.Text = "";
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            // Save the Text for user entered in Textbox1 for selected Value from List
        }

GridView Control with DropdownList and textBox

        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
            <Columns>
                <asp:TemplateField HeaderText="Option">
                    <ItemTemplate>
                        <asp:DropDownList ID="ddl" runat="server" Width="100px">
                        </asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Comment">
                   <ItemTemplate>
                        <asp:TextBox runat="server" ID="txt"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
