    Thanks.

    Please feel free to bump a thread it it leaves non answered. Please don't duplicate threads.

    To fix the problem, please add this code within a page's <head>.
    <ext:ResourcePlaceHolder runat="server" Mode="ScriptFiles" />
<script type="text/javascript">
    Ext.form.ComboBox.prototype.triggerBlur = Ext.form.ComboBox.prototype.triggerBlur.createSequence(function () {
        this.blur();
    });
</script>
    Here is the full code sample.

    Example

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

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<%@ Import Namespace="System.Collections.Generic" %>
<%@ Import Namespace="System.Linq" %>
<script runat="server">
    private object[] MyData =
        new object[] 
        {
            new object[] { "a" },
            new object[] { "b" },
            new object[] { "c" },
            new object[] { "a1" },
            new object[] { "b1" },
            new object[] { "b2" }
        };

    protected void Store_Refresh(object sender, StoreRefreshDataEventArgs e)
    {
        Store store = sender as Store;
        string filter = e.Parameters["query"];
        if (filter.Equals("*"))
        {
            store.DataSource = MyData;
        }
        else
        {
            store.DataSource = from x in MyData
                               where (x as object[])[0].ToString().StartsWith(filter)
                               select x;
        };
        
        store.DataBind();
    }
</script>

    Here is the improved fix.
    <ext:ResourcePlaceHolder runat="server" Mode="ScriptFiles" />
<script type="text/javascript">
    Ext.form.ComboBox.override({
        triggerBlur : function () {
            this.mimicing = false;
            Ext.getDoc().un("mousedown", this.mimicBlur, this);
        
            if (this.monitorTab && this.el) {
                this.el.un("keydown", this.checkTab, this);
            }
        
            this.checkOnBlur();

            Ext.form.TriggerField.superclass.onBlur.call(this);
        
            if (this.wrap) {
                this.wrap.removeClass(this.wrapFocusClass);
            }
        }
    });
</script>
    The fix has been added in SVN and will be available in a next official release.
