Hi Wayne,

Thank you for the feedback regarding the MultiColumnComboBox. Regarding your concerns, the Getting Started with MultiColumnComboBox article has been updated to mention the property and will be added to a demo soon after.

Regarding the highlighting itself, this is by design - when the property is set to true, the first item will always be highlighted, because it has the k-state-focused CSS class applied to it:

The class has the box-shadow property applied to it, to highlight it. You can remove the property entirely if you want by targeting the following CSS class selectors:

html body .RadMultiColumnComboBoxDropDown_Default .k-item.k-state-focused {
    box-shadow: inset 0 0 0 0;
}

Or you can make the box shadow stronger: 

html body .RadMultiColumnComboBoxDropDown_Default .k-item.k-state-focused {
    box-shadow: inset 0 0 0 2px rgba(0, 0, 0, 0.9);
}

I hope this clears things out.

Kind regards,

Hello,

After further investigation, we concluded that this is the intentional behavior of the MultiColumnComboBox control and, therefore not a bug - this is the feature that highlights the first item as soon as the DropDown is opened.

To remove it entirely, you can turn it off by adjusting the HighlightFirst property:

<telerik:RadMultiColumnComboBox runat="server" ID="RadMultiColumnComboBox1"  HighlightFirst="false" />

Hi Wayne,

Thank you for the screenshot and details on how to reproduce it. Indeed, you're right about this strange behavior of the MultiColumnComboBox and it was verified to be a bug. Your private post was converted to a public bug report, to share the problem with the community.

The bug seems to be resolved in the recent versions of the Kendo MultiColumnCombobox widget. Could you check its live demo at Kendo UI for jQuery MultiColumnComboBox and see if you experience the same behavior there too? If the issue is not reproducible we will fix it similarly in the MultiColumnCombobox AJAX wrapper too.

Kind regards,
