Mark Matches - Can't search for parentheses

[FTDEV129]

I am unable to find matching items that contain parentheses. I can successfully search for other special characters like '#', '%', '|', '*', etc. but not '('. In fact, it seems that typing '(' will clear the mask.

How do I go about searching for an item that contains parentheses?

Hi,

Thank you for reporting the issue and for your concern with the controls.

The issue seems to be a bug in the control that is caused by the fact that "(" and down arrow are both generating the keycode 40 and we are preventing the markMatch when the down key is pressed. 

I have logged the issue for fixing and you can follow its status and vote for it here.

As a temporary workaround you can use the code below:

<script>
             var $T = Telerik.Web.UI;
             var $LM = Telerik.Web.UI.RadListBox.Modules;
             $LM.MarkMatch.prototype.onKeyPress= function(e) {
                 var listBox = this._rlb;
                 var selectionModeReset = false;

                 var code = e.charCode || e.keyCode;

                 if (code < 32 && code != Sys.UI.Key.backspace && code != Sys.UI.Key.esc)
                     return true;

                 if(code == Sys.UI.Key.backspace)
                     e.preventDefault();

                 if ((code == Sys.UI.Key.esc || code == Sys.UI.Key.down || code == Sys.UI.Key.up) && !e.shiftKey) {
                     this._resetItems(this._items, true);
                     return false;
                 }

                 if (listBox.get_selectionMode() == $T.ListBoxSelectionMode.Multiple) {
                     listBox.set_selectionMode($T.ListBoxSelectionMode.Single);
                     selectionModeReset = true;
                 }

                 if (listBox._enableMarkMatches)
                     this._handleMarkMatches(code);
                 else
                     this._handleMarkFirstMatch(code);

                 // If the selection mode was Multiple before the event handling - set it back
                 if (selectionModeReset)
                     listBox.set_selectionMode($T.ListBoxSelectionMode.Multiple);

                 return true;
             }
      </script>

Hope this information will explain  the issue and be helpful.
