  • User-1305530094 posted

    Hi All,

    I use Cascading DropDown extender to populate my DropDown list via web method and its working perfectly fine, I get my fields populated with the text that I want and I can read their ids (SQL) using my vb.net

                                    <asp:DropDownList ID="MarStatTxt" runat="server" onkeydown="return (event.keyCode!=13)"
                                        CssClass="form-control mb-md" ClientIDMode="Static">
    <cc1:CascadingDropDown ID="cddlMarStatTxt" runat="server"
                                                        BehaviorID="cddlMarStatTxt" Category="MarStat"
                                                        LoadingText="Loading Marital Status..." PromptText="Select Marital Status"
                                                        TargetControlID="MarStatTxt" />

    once I add select2 plug in 

    <asp:DropDownList ID="MarStatTxt" runat="server" onkeydown="return (event.keyCode!=13)"
                                        data-plugin-selectTwo CssClass="form-control mb-md" ClientIDMode="Static">

    I can only read the text and I cant read the Id for that selected value.

    I noticed that after I select the value, my cascade DropDown extender does not read the value 


    without Select 2

    <input type="hidden" name="ctl00$tst$cddlMarStatTxt_ClientState" id="tst_cddlMarStatTxt_ClientState" value="1:::Single:::">

    with select2

    <input type="hidden" name="ctl00$tst$cddlMarStatTxt_ClientState" id="tst_cddlMarStatTxt_ClientState" value="::::::">

    any idea please on how i can get this feature to work?

    Hi Embryologist,

    According to your description, as far as I know, now your issue is you can not get the ID of the data through select2. 

    I am not clear why you use slelect2 with dropdownlist together. 

    About how to use select2, please refer to this sample:


    Also I am not clear you how to get the ID value? I hope you could post your completed code of your project.

    Best Regards,

    Eric Du
