Remove the possibility for one or more rows to be searched on.

In other words, it should not be possible to select disabled item rows by search.

It would be usefull to have a Property on the RadMultiColumnComboBox which represents the inputted searchtext. This Property should be TwoWay-Bindable.

A usecase for it could be to programmatically manipulate the searchtext.
For example setting it to NULL on LostFocus:

private void mccb_LostFocus(object sender, RoutedEventArgs e)
{
    this.mccb.ChildrenOfType<RadWatermarkTextBox>().First().Text = string.Empty;
}

Instead of hacking around with the visualTree etc. one could simply bind the property. This would also be MVVM compliant.

Proposed Name for the Property "SearchText".

The RadMultiColumnComboBox has a separate keyboard functionality executed when the watermark textbox (the search box) is focused and the dropdown is open. Basically, you can navigate through the rows of the gridview part and select them using the keyboard. 

Currently, this functionality is private. Introduce an API that allows you to customize the keyboard navigation. Consider something similar to the KeyboardCommandProvider of RadGridView.

the display of the drop-down part of the multicolumncombobox is different from the RAD combo box. There is an extra line between the content of the combo box and the drop-down button in the office 2016 theme at least. This should not be there to be consistent with the other combo boxes.
