    Hi there,

    I am new to RadControls, and I have the problem as follows:

    I put a Rad Combobox in the detailview. This combobox is bound with Sqldatasource so that the users can choose a item from this dropdownlist to insert/update into the database. Everything works fine.

    But I also want to set to allow Custom text, and when users want something which is not in the list, they can type in the box whatever they want to create new items. But I cannot find how to bind this new typed items with the database. Nothing happens when I type new texts into the box.

    Please help.

    Heya NT,

    Have you tried setting AllowCustomText=True on your combobox?  This should provide the desired functionality.  :)

    Thanks for your reply.

    Sure, I have set AllowCustomText="True". This allows me to type in the box perfectly. And I think my data binding is ok, because it works well when I choose items in the dropdownlist, but not with what I type in the box.

    Below is my code.


    <telerik:RadComboBox ID="rcbAddMenuGroup" runat="server" AllowCustomText="True" AppendDataBoundItems="True" DataSourceID="SqlDataSourceAddMenuGroup" DataTextField="cMenuGroup" DataValueField="cMenuGroup" EmptyMessage="Gõ tên để tạo nhóm mới, hoặc chọn từ danh sách hiện có." EnableItemCaching="True" EnableVirtualScrolling="True" ErrorMessage="Error." Font-Names="Arial" Font-Size="X-Small" HighlightTemplatedItems="True" LoadingMessage="Loading..." MarkFirstMatch="True" OffsetY="5" Skin="Default2006" Sort="Ascending" Style="position: relative; top: 0px; left: 0px;" Width="500px" SelectedValue='<%# Bind("cMenuGroup") %>'>

    <CollapseAnimation Duration="200" Type="OutQuint" />

    Hi NT,

    You can subscribe to TextChanged event of RadComboBox and update the database in its event handler.

    All the best,
