    [CLOSED] ComboBox: search not necessary at beginning

    Hello,

    I declare a combobox with local mode. I want to be able to do a search which not begin at the start of each item in the combo store which the default behavior of the combobox. Is there any option to set or how can I do it?

    Thanks in advance.

    Romuald.

    Hi,

    Imagine that there are the following items in the ComboBox: a, ab, ac, ba, bc.

    When type 'a' you need to show 'ba' and 'bc'.
    When type 'a' you need to show 'a', 'ab' and 'ac'.

    Do I understand you right?

    Thank for your reply.

    With your example

    Imagine that there are the following items in the ComboBox: a, ab, ac, ba, bc.

    When type 'a' I need to show all items that contain 'a'. For example 'a', 'ab', 'ac', 'ba'.

    For example if the contains 'Contact' when I type 'act' I need to show the 'Contact' items.

    To summarize the filter criteria is 'contain or any match' and not 'start with'

    Hope you understand

    Romuald.

    Thanks for the clarification, I understand now.

    Please look at the example.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.ComboBox1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { "1", "a" },
                new object[] { "2", "ba" },
                new object[] { "3", "aa" },
                new object[] { "3", "cca" },
                new object[] { "3", "cb" },
                new object[] { "3", "cbd" }
            };
            store.DataBind();
        }
    }
</script>
