Hello Everyone,

Can anyone suggest how to highlight the dropdown options upon mouse over. By default, I see a grey color highlighted when I hover on any of the options in the Dropdownlist. Please refer to the screenshot attached.

I would like to change the default color (grey) and give some brighter color for more visibility. 

ASP.NET version - Visual Studio 2013 Version 12.0
OS - Windows 8
exact browser version - IE >= 10
exact version of the Telerik product = 2009.1.527.35
preferred programming language = C#

Thanks in Advance!!

Kumar

Browser - safari version: 9.0.2 (11601.3.9)
Operation System  os version: OS X EI Captain version 10.11.2

I have a combobox, which uses treeview to show the data. 
When I click on combo box I get the following error

hi

I am applying a background color to all grid using this;

<style type="text/css">
      .RadGridHeaderStyle
        {
            background-color:#5e9cd2 !important;
            background-image:none !important;
            font-weight:bold !important;
            color:white !important;
        }

</script>

The header background color work fine but the font color on some columns don't seems to apply. I realised that it is because the column is sortable and the color won't change to white. How should make the sortable header font color to white? Thanks

Hello,

I have a RadComboBox with an associated required field validator. On Internet Explorer 11 (maybe other versions) an X appears that allows the user to clear the Combo. Please see the attached image if you don't know what I mean.

If the user clears the selection with the X and then clicks elsewhere (on another control for example) then the required field validator for the RadComboBox will activate. I only want this validator (and the other validators) to fire when the page is posted back.

There are a couple of the approaches that I have investigated but couldn't make get to work 100% correctly for various reasons are

1. Disable the validator temporarily with Javascript and re-enable later on. As per this thread Radcombobox clearSelection causes validation.
2. Use a custom validator.

The second one isn't really an option because the RadComboBox is used in an .ascx file that is re-used in a lot of places. Also, some attributes that are specific to a RequiredFieldValidator are required.

So, I am asking if there is a simple low impact way of preventing the validator from firing in this scenario?

Thanks in advance,
John.

I'm getting some weird go-slows with the following script.

Most of the time, the filtering works in about 50ms. Other times, it takes upwards of 8000ms. When this happens firefox pops up them message that the script is taking too long to execute (continue stop etc).

I've put some timers in to try and find out where it's chugging, and it is on this line

var item = listItems.getItem(count);

as to why... well that's the million dollar question

the mark up is contained as follows

Master page > Page > RadPageView > UserControl

(all declared at design time ~ no dynamically loaded controls)

The Code

-------------

    //
    // Escapes RegEx character classes and shorthand characters
    //
    escapeRegExCharacters: function (text)
    {
        return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&");
    },

    //
    // filter items in a Rad List box
    //
    filterListBox: function (pSearchBoxClientID, pUsersClientID)
    {
        var textBox = $('#'+pSearchBoxClientID);
        var listBox = $find(pUsersClientID);

        if (textBox != null && listBox != null)
        {
            var filterText = Core.escapeRegExCharacters(textBox.val());
            var expression = new RegExp(filterText, "i");
            var listItems = listBox.get_items();

            for (var count = 0; count < listItems.get_count(); count++)
            {
                var item = listItems.getItem(count);              
                item.set_visible(filterText == "" || item.get_text().match(expression));
            }
        }
    }

    <asp:TextBox id="txtSearchLinked" runat="server" CssClass="TextInput" Width="100%" />

            <telerik:RadListBox
                runat="server"

            </telerik:RadListBox>   

        /// <summary>
        /// Sets the JQuery event on the search text box

        private void SetupFilterEvent()
        {
            txtSearchLinked.Attributes.Add("onkeyup", "javascript:Core.filterListBox('" + txtSearchLinked.ClientID + "', '" + lstAccessInRole.ClientID + "');");
