    Hello, Telerik
    I have an RadComboBox:
    <telerik:RadComboBox runat="server" IsEditable="True" Width="167px" style="margin-left: 23px;" ID="cbMails" EmptyMessage="Choose a mail text"  OnSelectedIndexChanged="cbMails_SelectedIndexChanged" CssClass="ComboTop" AutoPostBack="True" meta:resourcekey="cbMailsResource1"></telerik:RadComboBox>

    And I have a button
     <asp:Button runat="server" ID="AddButton" Text="Add" CssClass="GreenContentButton"<br>                                    Width="60px" OnClick="AddButton_OnClick" meta:resourcekey="AddButtonResource1" />

    On button press I add new item in RadComboBox on server side.
    I want to be able to edit ComboBot item in it.
    I used IsEditable mode set to True but it does not work.
    In matter of fact it's not shown in intellitrace in regular Asp.Net.
    As far as I understood, it's available with silverlight and wpf versions of control. And by the logic in must be available in here, am I right?

    Please say I am)

    I suppose you want to allow the user to type in the input area of RadComboBox. You can set AllowCustomText property as true to achieve your scenario. Also check the following demo.

    Hello Vitalii,

    I can suggest you to use the FindItemByText() or FindItemByValue(), in order to access a specific item. Once you have an instance of the RadComboBoxItem, you could edit it and the changes would reflect immediately after the button Click event is fired. Please consider the following implementation at the OnClick event handler of the AddButton:

    protected void AddButton_Click(object sender, EventArgs e)
          RadComboBoxItem item = cbMails.FindItemByText("item2");
          if (item != null)
              item.Text = "Item2Item2";
