Handle Exceptions in StoreFile of the Custom FileBrowserContentProvider

Dear Support,

I have created a custom class that inherits from FileBrowserContentProvider and have implemented all the neccesary methods. I sometimes require to reject an uploaded file in the StoreFile method due to some business logic but was not able to figure how that could be implemented. Returning a non-empty string and throwing an exception did not work well. Since the class inherited from FileBrowserContentProvider has no access to the Page-derived class, I am not able to add an Error to the page.

Could you please help in directing me to a neat solution to my problem?

Thanks in advance,

Omtara

RadComboBox with checkboxes item template does not work properly on IE6

Hi,
I am using RadComboBox with item template of checkboxes as described in the demo:
http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultcs.aspx

I am setting the checked items using javascript. this code works perfectly on all browsers but IE6. in IE6 the checkboxes are not checked.

Has anybody encoutered such problem?

This is my javascript code:

    
            function onCheckBoxClick(chk) {  
        
                        var combo = $find("<%=cmbExt.ClientID %>");  
        
                        //holds the text of all checked items  
        
                        var text = "";  
        
                        //holds the values of all checked items  
        
                        var values = "";  
        
                        //get the collection of all items  
        
                        var items = combo.get_items();  
        
                        //enumerate all items  
        
                        for (var i = 0; i < items.get_count(); i++) {  
        
                            var item = items.getItem(i);  
        
                            //get the checkbox element of the current item  
        
                            var chk1 = $get(combo.get_id() + "_i" + i + "_chk1");

External CSS question

Hi,

I link an external CSS file to an Editor from codebehind:

NLtext.CssFiles.Add("~/" & TablePrefixStrip & "/css/telerik.css")

This works OK, the stylesheet is coupled.
But when I try to select classes from this sheet and add it with

NLtext.CssClasses.Add("Links class ", ".link")

it cannot find the classes. I think this problem occurs when a stylesheet is coupled which lies above the root of our CMS.

But even when I try

NLtext.CssFiles.Add("http://f2p-server:8136/css/telerik.css")
NLtext.CssClasses.Add("Links class", ".MarLeft")

It is not working.

Please assist, TIA

In-place editing with popup

I have a telerik grid control and use in-place editing. Since telerik does not support checkboxlist columns, I want to popup a small window with a checkboxlist and a close button when the user clicks on a cell that requires the user to select multiple items. When the close button on the popup is hit, I want to populate the cell with a comma separated list of choices selected. Is this possible and is there an example that I can look into for doing this?

Thanks

buttons show default before being skinned

I am using the form decorator and in IE8 I see my buttons on the page and then they blink into the skinned version. In IE7 the blink happens faster, but it's still there... I have just finished installing the lastest version of rad controls, hoping that would fix my issue - it does not. The odd thing is that on your demo page, the buttons don't show at first then the skinned versions appear. I looked at the source, and it doesn't look like your doing anything special to hide them in code behind or HTML. The only forum posts I can find on the subject are from 2008 so I'm not clear if this is a generally accepted issue or not. I have fixed the padding issue using css, but I still have the blinks. Help.
