Is there a way to add scrolling for dynamically added items to the sub menu? I've got many items loaded from ajax calls and dynamically added to the sub menu of my RadContextmenu on a RadGrid. Currently they are expanding beyond the boundaries of the viewport w/o any means to scroll to the bottom of them...

Here is my front end menu settings:

Below is JS to load and add the dynamic items to the sub menu:

And adding conditionally other root items and the "load task" item to contain the sub menu in the back end, triggered upon page_load:

I tried to set the default height both in the back end and on the menu tag, as well as disabling animations, removing autoscroll handler upon menu closure etc, per suggestions from other threads, so far all to no avail...

Any ideas?

So I have this binding problem

I want to bind a radgrid to List<Class1>

On the grid I want to display the following columns:

UserName

Make

Model

I also want the Make and Model to be grouped by UserName

The classes:

    public class Class1

    {

        public Class1()

        {

            Class2Objects = new List<Class2>();

        }

        public string Username { get; set; }

        public List<Class2> Class2Objects { get; set; }

   }

Public class Class2

{

               Public string Make{get;set;}

               Public string Model{get;set;}

}

The issue is I don't know how to bind to the sub-collection Class2Objects property of Class1

Can this be done

Thanks,

William

Please fix.  This is really annoying because all controls in the RadGrid will then have a Visible property value of false, even if they are visible.

I have a RadSplitter which house 2 vertical RadPanes both with scroll bars.

The first pane has a RadTreeView inside a .Net User control and the second pane has an IFrame.

I need to set focus on a particular node in the RadtreeView when the page is loaded so I don't have to scroll endlessly to reach that node when the page is first loaded.

I tried using the following approach but it is not working :

function scrollToNode(){
        var selected = $(".rtSelected");
        if(selected.length > 0){
        var TotalScrollNeeded = selected.offset().top
            - $("#radTree").offset().top
            + $("#radTree").scrollTop();
        $("#radTree").animate({ scrollTop: TotalScrollNeeded }, 1000);
        }

I have a SearchBox with a 'none' display style declared in a holding div.

After a javascript event (example click on a button, without postback) I am dynamically creating a new div, and move the SearchBox to it.

I have to do this, because it seems that it is not possible to dynamically create a SearchBox from javascript.

I based the initial hide/show on the post of Brian Azzi.

Everything works fine, but the magnifying glass appears  in on the left of the SearchBox instead of the right side. I attached a screenshot of it.

And that is annoying.

Any solution for that?

I am posting a sample of the xml and javascript I am using.

The other problem I have is that this._typeSearchBoxInput does not seem to be a proper Telerik control.

Because when I try to use get_inputElement() on it, I get an undefined exception.

I just recently upgraded a project to the latest release (2016.1.113) and am experiencing a change in the appearance of panel headers. Prior to the update the header was highlighted with the reverse/selected when open. After the update only the last panel selected is highlighted. We are using the Metro touch skin (this is a mobile site) and the headers are now difficult to distinguish from the content. Please see the attached screen shot. How do I restore this to have the panel header always highlighted? here is my markup code:

Thanks.

Hi,

I'm making some progress formatting the header row of my Excel export, but I'd really like to have the columns automatically adjust to fit the width of the content.

Here's my OnInfrastructureExporting event handler:

I've seen similar threads but they are related to export formats other than Xlsx.

Any idea how I can accomplish auto-fit using the above handler?  Or do I need to do that elsewhere?

Thanks for any advice.

I am having a problem validating the Async File upload control, using a Custom Validator and JavaScript.

The JS I'm using is:

 function isAttachmentValid(sender, args) {

var upload = $find("<%= RadUpload1.ClientID %>");
    args.IsValid = upload.getUploadedFiles().length != 0;

}

This works perfectly fine if I submit the form right away, but if I save the form and come back to it upload.getUploadedFiles().length always = 0 and validation fails.

I should also note that I don't have access the server-side code so validation must be done on the client.

Hi,

I'm programmatically creating a grid on the server side, and would like to use the HeaderContextMenu to allow filtering (particularly, we're interested in the 2-step filtering provided in the menu). Because the other options are available elsewhere or are not used in our system, we'd like to have the context menu simply show the "filter" submenu. I can remove elements of the context menu using this code:

In the attached image, the red-bordered menu is what we'd like to appear when right-clicking a column title.

Is there a way for me to do this? I've tried hooking into various menu events to replace the menu items with the filter menu, but it seems like it's not possible. The closest I can get so far is the top-level menu simply having the "Filter" option, which opens the Filter Menu. I'd like to skip that first step and just have the filter menu appear.
