0
I am trying to set value to raddropdownlist using javascript but getting select is undefined.
var dropdownlist = $find("<%= rcbLayout.ClientID %>");
var item = dropdownlist.findItemByText(rlvControllers._dataSource[itemIndex].FORMLAYOUT);
item.select();
markup:
<asp:Label ID="LayoutLabel" runat="server" Text="Form Layout:"></asp:Label>
<telerik:RadDropDownList RenderMode="Lightweight" ID="rcbLayout" Width="250px" DataTextField="TEXT" DataValueField="VALUE" runat="server"></telerik:RadDropDownList>

Use the DevTools HTML inspector to find the item ID and compare it with the value returned by rlvControllers._dataSource[itemIndex].FORMLAYOUT. Check this blog post of how to inspect the generated HTML by the control - telerik.com/blogs/…
