[Solved] get_value() not returning the value

[Michael Pullella]

Hello
I am filling my combobox with data in this manner (I can see the DataTextField)

 

            EntityType[] entityTypes = WritingPresenter.GetEntityTypes();

            this.ddlType.DataSource = entityTypes;
            this.ddlType.DataTextField = "Type";
            this.ddlType.DataValueField = "GUID";

            this.ddlType.DataBind();

I am trying to retrieve the selectedvalue via Javascript by doing this:

 

        var combo = <%=ddlType.ClientID %>;
        returnVals.type = combo.get_value();

However, when the javascript runs, I get a Microsoft JScript runtime error: Object doesn't support this property or method when it tries to get the value.

Interestingly, if I look at the html that gets generated, I do not see the dataValue:

<div class="rcbSlide" style="z-index:6000;">

<div id="ddlType_DropDown" class="RadComboBoxDropDown RadComboBoxDropDown_Default " style="float:left;display:none;">

<div class="rcbScroll rcbWidth" style="width:100%;">             <ul class="rcbList" style="list-style:none;margin:0;padding:0;zoom:1;">

<li class="rcbItem ">Passport</li>

<li class="rcbItem ">Individual</li>             </ul>

</div>

</div>

</div>

<input id="ddlType_ClientState" name="ddlType_ClientState" type="hidden" />

Here is the markup from the aspx page:

                    <telerik:RadComboBox ID="ddlType" runat="server" Width="100%">
                    </telerik:RadComboBox>

Do I need a few more properties on my RadComboBox to get this working?

Hi Michael,

You have to use $find() method in order to access the client side object of RadComboBox.
          var combo = $find("<%= RadComboBox1.ClientID %>");

Use the following client code for getting the vaue from client.
JavaScript:

    function getvalue() {
          var combo = $find('<%=ddlType.ClientID %>');
          alert(combo.get_value());
    }
