    Hi,

    I'm trying to get my radcombobox (populated with checkboxes) to show what items are selected. Its similar to this demo:
    http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultcs.aspx

    However, my js code (copied from the above is simply returning empty strings with the .get_text() method.

    Can anyone shed some light on why its returning nothing?

    <telerik:RadComboBox ID="RadComboBox_User_Type" runat="server" EmptyMessage="Select Users" HighlightTemplatedItems="true"
                AllowCustomText="true" Width="225px">
                <Items>   
                    <telerik:RadComboBoxItem 
                        ImagePath="../Images/OnTime_Fkeys/Access Control.png" 
                        Text_="Employee">
                    </telerik:RadComboBoxItem>   
                    <telerik:RadComboBoxItem 
                        ImagePath="../Images/OnTime_Fkeys/Access Control.png" 
                        Text_="Visitor">
                    </telerik:RadComboBoxItem>
                </Items>
                <ItemTemplate>
                    <div onclick="StopPropagation(event)" style="vertical-align: middle">
                        <asp:CheckBox runat="server" ID="chk1" Checked="false"/>
                        <asp:Label runat="server" ID="Label1" AssociatedControlID="chk1">
                            <img src='<%# DataBinder.Eval(Container, "Attributes['ImagePath']") %>' alt="" style="vertical-align:text-top"/>
                            <%# DataBinder.Eval(Container, "Attributes['Text_']") %> 
                        </asp:Label>
                    </div>
                </ItemTemplate>
            </telerik:RadComboBox>




    protected void Page_Load(object sender, EventArgs e)
            {
      
                String script1 = "" +
                        "function StopPropagation(e) " +
                        "{" +
                            "e.cancelBubble = true;" +
                            "if (e.stopPropagation) " +
                            "{" +
                                "e.stopPropagation();" +
                            "}" +
                        "}";
      
                ScriptManager.RegisterStartupScript(Page, Page.GetType(), "LMP_Stop_Prop", script1, true);
      
                ClientScript.RegisterClientScriptBlock(Page.GetType(),"324nvik",
                    "<script src=\"../Javascript/Live_Monitor/Live_Monitor.js\" type=\"text/javascript\"></script>");
      
                for (int i = 0; i < RadComboBox_User_Type.Items.Count; i++)
                {
                    RadComboBox_User_Type.Items[i].DataBind();
      
                }
      
                foreach (RadComboBoxItem item in RadComboBox_User_Type.Items)
                {
                    CheckBox chk = (CheckBox)item.FindControl("chk1");
                    chk.Attributes.Add("onclick", "onCheckBoxClick(this)");
                }
      
            }
        }


    Live_Monitor.js
    function onCheckBoxClick(chk) {
      
        var combo = $find('RadComboBox_User_Type');
        var text = "";
        var values = "";
        var items = combo.get_items();
      
        for (var i = 0; i < items.get_count(); i++) {
            var item = items.getItem(i);
            var chk1 = $get("RadComboBox_User_Type" + "_i" + i + "_chk1");
      
            if (chk1.checked) {
                text += item.get_text() + ",";
                values += item.get_value() + ",";
            }
        }
          
        text = removeLastComma(text);
        values = removeLastComma(values);
          
      
        if (text.length > 0) {
            combo.set_text(text);
        }
        else {
            combo.set_text("Select Users");
        }
    }
      
    function removeLastComma(str) {
        return str.replace(/,$/, "");
    }


    Anyone any ideas????

    Thanks,

    Sunny

    Hello Sunil,

    You should use the following:
    item.get_attributes().getAttribute("Text_")
    instead of
    item.get_text()
