[2005] Checkbox/radiobuttonlist next to childs in master/child data

[Guiseppe]

Hi,

I've got some master/child data and I want to display a checkbox or radiobutton next to each child, depending on a value the master has.

The checkboxes or radiobuttons should also be grouped for each master record. (each master record would have a list of controls, one control next to each of his children).

I am currently displaying the data (without checkbox/radiobuttons) using a nested repeater, but I'm at a loss on how to manage the checkbox/radiobuttons.

I already tried manually putting either a checkboxlist of radiobutton list in ascx file, but I noticed I couldn't put the list above the repeater and dynamically add a listitem for each row.

Any pointers would be welcome.

Show your ItemTemplate.

    <asp:Repeater ID="question" runat="server" OnItemDataBound="question_ItemDataBound">
        <ItemTemplate>
            <tr>
                <td >
                    <%# DataBinder.Eval(Container.DataItem, "Description") %></br>
                </td>
            </tr>
            <tr>
                <td align="right">
                    <table border="0">
                        <asp:Repeater ID="answer" runat="server">
                            <ItemTemplate>
                                <tr>                             
                                    <td>                 
                                        <%# DataBinder.Eval(Container.DataItem, "Description") %>
                                        </br>
                                    </td>
                                    <td>
                                        <asp:RadioButton ID="RadioButton1" runat="server" />
                                    </td>        
                                </tr>
                            </ItemTemplate>
                        </asp:Repeater>
                    </table>
                    <br />
                </td>
            </tr>
        </ItemTemplate>
    </asp:Repeater>

(Both question and answer tables have a description field)

protected void question_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        RepeaterItem item = e.Item;
        if ((item.ItemType == ListItemType.Item) || (item.ItemType == ListItemType.AlternatingItem))
        {
            Repeater Answer = (Repeater)item.FindControl("answer");
            DataRowView drv = (DataRowView)item.DataItem;
            Answer.DataSource = drv.CreateChildView("Question_Answer");
            Answer.DataBind();
        }
    }

So shouldn't you just place the master radiobuttons like here:

    <asp:Repeater ID="question" runat="server" OnItemDataBound="question_ItemDataBound">
        <ItemTemplate>
            <tr>
                <td >
                    <%# DataBinder.Eval(Container.DataItem, "Description") %></br>
                    <asp:Radiobutton............................ />
                </td>
            </tr>
            <tr>
                <td align="right">
                    <table border="0">
                        <asp:Repeater ID="answer" runat="server">
                            <ItemTemplate>
                                <tr>                             
                                    <td>                 
                                        <%# DataBinder.Eval(Container.DataItem, "Description") %>
                                        </br>
                                    </td>
                                    <td>
                                        <asp:RadioButton ID="RadioButton1" runat="server" />
                                    </td>        
                                </tr>
                            </ItemTemplate>
                        </asp:Repeater>
                    </table>
                    <br />
                </td>
            </tr>
        </ItemTemplate>
    </asp:Repeater>

That would show 1 radiobutton for each question. I need one for each answer in each question, grouped by question.

I found out I could manually assign them a group, for instance the questionID. However, that created a problem since ASP renames all the controls when generating the html so they 'wouldn't' end up in the same group after all.

A workaround would be to use a custom radiobutton control that overrides some functionality regarding the name change.

Ah, now I see what you mean. Yes, ASP.NET does rename these controls and you do end up with independent radio buttons.

How about using a RadioButtonList which, in the ItemDataBound event, you bind to a dataset containing specific answers?
