EnableFilteringOnEnterPressed In Firefox Possible Bug

[Paul Herzberg]

Hello,

If I choose the following for RadfileExplorer:

 EnableFilterTextBox="true" EnableFilteringOnEnterPressed="true"

When I go straight to the text box and enter a term, the "Back" button gets focus and nothing else seems to happen, but only in Firefox. IE10 works as you would expect.

If it helps here is some background. The company I work for is using the Fileexplorer as part of an editting tool. The Fileexplorer allows our users access to files that they have uploaded to the companies CMS system.

I have created a Filesystemprovider that gives access to files depending on the user and where they are accessing the editting tool.

I have extended this provider to have information about the default "alternative text" for images and store this in the FileItem.Path variable as a csv variable. The path looks like this:

Uploads/2350|0|0|ALTDESC|1|15.01.2013 16:49:47|0

I've bolded the information I want to using in the filter.

The whole thing breaks down like this: virtual path / fileid | height | width | alt description | boolval| upload date | boolval

So, in order to filter with this extra field I have to catch the filter command and then do a postback of my own, because the FilterText value is inaccessable in the code behind I have to put this in a hidden field, this I do like so:

function explorerFilterHandler(explorer, args)
{
        args.set_cancel(true);
	hField = $get("<%= explorersFilterValue.ClientID%>");
	hField.value = args.get_text();
	__doPostBack(hField.name, "");
}

As per another forum post.

Because the filter text is deleted on postback I have to refill the text box and then set the cursor to the end of the text once the OnClientLoad of the FileExplorer is fired (Onclientload = "setFilter"):

         function setFilter(){   
            var hField  = $get("<%= explorersFilterValue.ClientID%>");
            if(hField.value != ''){
                var filter = $('input[id$="FilterTextBox"]');
                filter.val(hField.value);
                filter.focus()
                setSelectionRange(filter[0], hField.value.length, hField.value.length);
            }
        }
 
        function setSelectionRange(input, selectionStart, selectionEnd) {
            if (input.setSelectionRange) {
                input.focus();
                input.setSelectionRange(selectionStart, selectionEnd);
            }
            else if (input.createTextRange) {
                var range = input.createTextRange();
                range.collapse(true);
                range.moveEnd('character', selectionEnd);
                range.moveStart('character', selectionStart);
                range.select();
            }
        }

Because this postback can be slower than a typist can put in the letters this can mean text disappears if the user is not careful, so it was decided the use the EnableFilteringOnEnterPressed setting.

I thought that, perhaps, the error could have been caused by all this extra work, but it seems when I add a simple FileExplorer to a different page, the same thing happens.

It may simply be that I have missed something.

Thank you for your help in this matter.
