I´m working with the thread here - https://demos.telerik.com/aspnet-ajax/editor/examples/dbfilebrowsercontentprovider/defaultvb.aspx?show-source=true

that the user can create folders, upload, delete files and everything will be stored in a single table in the database. No physical files or folders will be created on the server. Accessing the files from the database is performed with a HTTP handler (<em>Handler.ashx</em>).

It is working fine in development and uat environment. In Production environment, when I select a file to upload it, the upload button gets disabled immediately.

What does it wrong? Please suggest as it is very urgent and Thanks in advance.

Hi. I have a treeview and am using a context-menu to open a RadWindow. I am then attempting to refresh the treeview in the OnClientClose event of the RadWindow using an ajax call. Everything is working great except for the final client-side ajax call in OnClientClose. It appears to be complaining about the $
in the call 'Main$NavigationTreeView.UniqueID' where Main is the Content ID.

withing the content tag of the webform
<asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="Server">

1. My RadAjaxManager declaration in my master page:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ><telerik:AjaxSetting AjaxControlID="Main$NavigationTreeView">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="Main$NavigationTreeView" LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
</telerik:AjaxSetting> 

2. Treeview and RadWindow declaration in webform:

<telerik:RadTreeView runat="server" ID="NavigationTreeView" OnContextMenuItemClick="NavigationTreeView_ContextMenuItemClick" ...>
<ContextMenus>
<telerik:RadTreeViewContextMenu ID="MainContextMenu" runat="server">
<Items>
<telerik:RadMenuItem Value="EditNode" Text="Edit node"></telerik:RadMenuItem>
<telerik:RadMenuItem Value="NewNode" Text="New node"></telerik:RadMenuItem> 
<telerik:RadMenuItem Value="DeleteNode" Text="Delete node"></telerik:RadMenuItem>
<telerik:RadMenuItem Value="CopyNode" Text="Copy node" ></telerik:RadMenuItem>
 </Items>
</telerik:RadTreeViewContextMenu>
</ContextMenus>
</telerik:RadTreeView> 

<telerik:RadWindowManager id="Singleton" runat="server">
<windows>
<telerik:RadWindow id="DialogWindow" Behaviors="Close"
OnClientclose = "OnClientClose" Left="250px" Modal = "true" Runat="server" NavigateUrl="./TreeViewDialog.aspx">
</telerik:RadWindow>
</windows>
</telerik:RadWindowManager>

3. Declaration of OnClientClose in webform:

<

telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript"> 
function OnClientClose(radWindow){
var AJAXMgr = <%= RadAjaxManager.GetCurrent(Page).ClientID %>;
AJAXMgr.AjaxRequestWithTarget('<%= Main$NavigationTreeView.UniqueID %>', '');
} 
</script>
</telerik:RadCodeBlock> 

Is this the correct way to do it? What am I doing wrong?

Kind Regards,

Hi,

With the new Q2 2018 I get TypeError: access to strict mode caller function is censored on FireFox 60.0.1 and Chrome 66, when I use the upload function of the Editor.

This also happens when I try the same in the Telerik demo environment, please refer to screenshot .

BR, Marc

Using objectdatasource.  Found a thread from a while ago about adding the  OverrideDataSourceControlSorting="true".  Still makes our column headers disappear and not sortable. Any thoughts would be great.

Thanks

I would like to duplicate the functionality show in this codepen: (https://codepen.io/joshnh/pen/vOxxQX?editors=110).  At 600px, it stacks the table header on the left side, and the data on the right side.  I have a RadGrid with over 20 columns, and to make this mobile-friendly I'd like to be able to create the same affect on a RadGrid.

This approach appears to be dependent on having data-labels on the <td>.  I see the grid headers are rendered as a th, but I don't see a way to have a data-label on the <td>.  Is there any way to make the UniqueName render as a data-label, or is there some other approach that can make RadGrids columns stackable with the header name on the left side?

Thank you.

I am using custom FileSystemContentProvider class for FileExplorer's ContentProviderTypeName configuration.

I am using HTTPHandler to download files on double click on Files .

When double Clicked it opens files to download but it also opens a RadWindow . is there way to stop the popup and get the files downloaded directly?
