    I have a situation where i have a listview with a itemtemplate, the template contains a set of radiobuttons and a combobox. Based on the checked value of the radiobutton i need to set the datasource on the combobox but not sure how to accomplish this in the best manner.

    My listview,

    <telerik:RadListView runat="server" ID="lvTimers" OnNeedDataSource="lvTimers_NeedDataSource">
                                        <div class="timer col-xs-12" data-timerid="">
                                            <div class="row">
                                                <div class="col-xs-3 col-md-2 col-lg-2 center-xs">
                                                    <span class="hours">1</span>:
                                                    <span class="minutes">21</span>:
                                                    <span class="seconds">31</span><br />
                                                    <asp:ImageButton runat="server" ID="btnStart" Visible='<%# Eval("StartTime") == null   %>' ImageUrl="~/images/web/icons/play.png" CommandArgument='<%# Eval("TimerId") %>' />
                                                    <asp:ImageButton runat="server" ID="btnPause" Visible='<%# Eval("StartTime") != null   %>' ImageUrl="~/images/web/icons/pause.png" CommandArgument='<%# Eval("TimerId") %>' />
                                                <div class="col-xs-8 col-md-9 col-lg-9">
                                                    <asp:RadioButtonList runat="server" ID="rbType" RepeatDirection="Horizontal">
                                                        <asp:ListItem Value="1" Text="Frånvaro"></asp:ListItem>
                                                        <asp:ListItem Value="2" Text="Intern"></asp:ListItem>
                                                        <asp:ListItem Value="3" Text="Extern"></asp:ListItem>
                                                        <asp:ListItem Value="4" Text="Övrigt"></asp:ListItem>
                                                    <telerik:RadComboBox runat="server" ID="cmbCustomers"></telerik:RadComboBox>
                                                    <telerik:RadComboBox runat="server" ID="cmbProjects"></telerik:RadComboBox>
                                                    <%# Eval("TimerId") %>
                                                <div class="col-xs-1">
                                                    <asp:ImageButton runat="server" ID="btnDelete" ImageUrl="~/images/web/icons/delete.png" CommandArgument='<%# Eval("TimerId") %>' />
                                                    <asp:ImageButton runat="server" ID="btnUpdate" ImageUrl="~/images/web/icons/update.png" CommandArgument='<%# Eval("TimerId") %>' />
                                                    <asp:ImageButton runat="server" ID="btnSave" ImageUrl="~/images/web/icons/save.png" CommandArgument='<%# Eval("TimerId") %>' />


    Any helpful soul with any idea how to go about this?

    Hello Christian,

    You can achieve this requirement using the following approach:
    <asp:RadioButtonList ... AutoPostBack="true" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
    protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
        RadioButtonList list = sender as RadioButtonList;
        RadListViewDataItem item = list.NamingContainer as RadListViewDataItem;
        RadComboBox combo = item.FindControl("cmbCustomers") as RadComboBox;
        // execute custom binding logic to refresh the combo options

    I hope this will prove helpful.
