A workaround is to disable the embedded jQuery and use an older version (for example, 1.11.1 which is the previous version the suite used): https://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/disabling-the-embedded-jquery

Repro steps:

- Put a searchbox on the page with some data source
- Hook its postback handler, OnSearch
- search something in it, select the item to postback

expected: search fired

actual: JS error in FF


        <telerik:RadSearchBox RenderMode="Lightweight" runat="server" ID="RadSearchBox1"
            DataTextField="Name"
            DataValueField="id"
            OnSearch="RadSearchBox1_Search">
        </telerik:RadSearchBox>


    protected void Page_Load(object sender, EventArgs e)
    {
        RadSearchBox1.DataSource = GetData();
        RadSearchBox1.DataBind();
    }
    protected DataTable GetData()
    {
        DataTable tbl = new DataTable();
        tbl.Columns.Add(new DataColumn("id", typeof(decimal)));
        tbl.Columns.Add(new DataColumn("Name", typeof(string)));
        tbl.Columns.Add(new DataColumn("Reason", typeof(string)));
        tbl.Columns.Add(new DataColumn("someField", typeof(decimal)));
        tbl.Columns.Add(new DataColumn("anotherField", typeof(string)));
        tbl.Rows.Add(new object[] { 1, "one", "fi\\nrst", 2, "5" });
        tbl.Rows.Add(new object[] { 2, "two", @"se\ncond", 3, null/*SIMULATE EMPTY VALUE*/ });
        tbl.Rows.Add(new object[] { 3, "three", "third", 4, "5" });
        tbl.Rows.Add(new object[] { 4, "four", "fourth", 5, "5" });

        return tbl;
    }

    protected void RadSearchBox1_Search(object sender, SearchBoxEventArgs e)
    {
        Response.Write(DateTime.Now.ToString());
    }

When the SearchBox is on the right side of the screen and the dropdown width is larger than the SearchBox width, the dropdown goes outside the viewport:

Expected/fixed: https://www.screencast.com/t/smfPgy767M

Workaround: 

<script>
    function OnClientLoad(sender, args) {
        sender._dropDown.on({ "reflowed": sender._onReflowed }, sender)
    }

    Telerik.Web.UI.RadSearchBox.prototype._onReflowed = function () {
        var that = this;
                       
        var $animationContainer = $(that._dropDown._animationContainer);

        if (that._enableScreenBoundaryDetection) {
            var availableSpace = that._dropDown._getAvailableSpace();
            var tableWidth = $(that._innerWrapElement).outerWidth();
            var dropDownWidth = $animationContainer.outerWidth();
            var overflow = dropDownWidth - (tableWidth + availableSpace.right);

            if (overflow > 0) {
                var left = parseInt($animationContainer.css("left"), 10);
                var newLeft = Math.max(left - overflow, left - (dropDownWidth - tableWidth));

                $animationContainer.css("left", newLeft);
            }
        }
    }
</script>
<telerik:RadSearchBox runat="server" ID="RadSearchBox1"

Validation is not implemented for RadSearchBox.

You can find attached an example that emulates validation of a search box through a dummy textbox and validators attached to that dummy textbox.

Can I advice to extend SearchBox or RadAutoCompleteBox control to write free text and open list box only if I digit a custom char like '@'?
I am tinking a control like Post textbox in Facebook or in Twitter where I can digit text and, if I digit '@' char opens a list with all friends o mine.

If you want extend more, it will be wonderful if you can associate more than one custom char and each custom char is associated to a different Data source.
Example:
- '@' to get products
- '#' to get Customers
- and so on...

This SearchBox must can be multiline too.

Thanks,
Francesco.

Please implement WAI-ARIA support in RadSearchBox with and without a Search Context.

It needs the same type of logic added as the AutoComplete and ComboBox control so that JAWS can speak and navigate the list items properly.
It looks like there was a little started because it renders an ARIA live region for status, but never writes to it from what I can tell.

I know this document lists the current controls that support ARIA - http://docs.telerik.com/devtools/aspnet-ajax/controls/wai-aria-support-and-screen-readers

Thanks,

Hi, in SearchBox, when the field being searched is a date, we would like to be able to search via the 'smart parsing engine' of DateInput.

In certain scenarios time between clicking (focusing ) the SearchBox and being able to interact with it.

The issue is iOS7 / Safari specific
