If you go at the demo https://demos.telerik.com/aspnet-ajax/fileexplorer/examples/server-sideapi/dbfilebrowsercontentprovider/defaultcs.aspx and try to rename the file with a extension that are not accepted (example ".txt" that are not in Configuration.SearchPatterns) you obtain the message "The selected folder could not be created because the application did not have enough permissions. Please, contact the administrator.".
The same error are displayed if you edit have the Configuration-AllowFileExtensionRename="false" and use a dot in the name of file.

This message are inappropriate for the context.

Hello,

 I have a <telerik:RadGrid> which contains some <telerik:GridBoundColumn> elements. Until now the AutoPostBackOnFilter value was set to true. This means the grid had its contents updated every time I left the focus of one of the GridBoundColumns. This is not a desired behavior anymore. Now I just want to trigger the filtering manually by let's say clicking on a button. So I set all the AutoPostBackOnFilter values to false and created a button with the according serverside event handler, which is empty so far :)

 How could I implement this requirement?

 Thanks in advance!

I have a situation in which I create the next level of items in a TreeList in the ChildItemsDataBind event.

At some levels of the tree, there are a large number of child items being created.

And, each of these items requires a lengthy query to obtain the fields to populate it.

This scenario can take as long as 10 seconds or more in some cases.

When this case arises, the user has no idea if anything is happening and may believe the page is frozen or has crashed.

I need to display a ProgressArea or UpdateProgress to make it clear work is being done.

I can do this no problem by initiating the process with something like a button click event.

What I would like to do is have this process initiated when a specific item of the TreeList level is selected.

Is there a way to initiate and display a ProgressArea or UpdateProcess from some TreeList event?

I'm trying to get a row of a TreeList to change appearance when the mouse is over it.

I can do this in css style for a GridView.

But there doesn't seem to be similar functionality for a tree list row.

Does anyone know if this can be done?

We did some research on Azure Bot Framework and we found out that we need to use code to build our Chatbot's dialog.

Does Telerik has plan to build something similar to IBM Watson Assistant's visual dialog editor?
Screencap: https://www.ibm.com/cloud/watson-assistant/assets/img/image_1.png

The visual dialog editor is very easy to use to create complex dialogues for their Chatbot.

Thanks.

Hi

I am implementing a reporting dashboard ASP.NET page. To do this I have an ASPX page with multiple RadDockZones and RadDocks, each containing a reference to a user control (ASCX page) which contains the RadHtmlChart.

Several of these charts have drill-downs which use RadAjaxManager and a client side function called from the chart. See...

https://demos.telerik.com/aspnet-ajax/htmlchart/examples/drilldownchart/defaultvb.aspx

Individually, the charts work fine but when incorporated within the parent dashboard page I get a message saying you can't have more than one RadAjaxManager on the same page.

Google searches told me to use RadAjaxManagerProxy instead, with the RadAjaxManager on the parent page. However, I have no idea how to do this. None of the solutions I found seem to be suitable for my problem. One said that RadAjaxManagerProxy does not have client-side object or functions. I am using the ajaxRequest client-side function, so perhaps this is my problem.

Is what I am trying to do even possible? If so, how?

Thanks

Nick

Hi

I hope you can help. We are implementing a .NET reporting dashboard whereby our page will consist of multiple RadHtmlChart controls. Each control sits in its own web part called from the parent page and housed in RadDocks.

For performance reasons we'd like the charts to render asynchronously. We have tried to achieve this using a web service in the manner shown below.

However, the charts do not render at all. Any other control we place in our web parts work fine (dropdown, radgrid etc.). Just not RadHtmlChart. Have you any ideas why this would be? Should we be using another method of doing this?

function DockInitialize(dock, args) {

            logIt("INVOKE WidgetsWebService:" + dock.get_id());
                var dockID = dock.get_id();
                var CompanyID = $get(dockID).attributes["CompanyID"].value;
                Revolution.WidgetsWebService.GetData(CompanyID, function (result) {
                    $get(dockID + "_C").innerHTML = result;
                    logIt("END INVOKE WidgetsWebService:" + dock.get_id());
                });
        }
