The tag keeps coming up as not being recognized in the mark up. I have tried using it in other web application where I use radcontrols such as button and pop up windows, and I get the same behavior, it recognizes all the other mark up tags but not the raddataform

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:RadDataForm RenderMode="Lightweight" runat="server" ID="RadDataForm1"
                ...
            </telerik:RadDataForm>

Thanks in advance for any help.

Hi,

A couple of months ago our company were alerted to a Telerik security issue with 2 of the DotNet 4.5 web sites we host / support. We followed the advice and patched the dll and made some amendments in the web.config to prevent AsyncUpload functionality.

Since the patches were added the performance of both sites (on 2 different Rackspace servers) have slowed up to virtually unusable levels. No other changes have been made to the code or setup of the sites/servers as these are not actively developed due to their age (lost count how many times have we expressed a need to upgrade the sites!).

Has anyone ever experienced a similar situation or got any ideas what may have caused the issue and how to get functioning sites back?

Dear Folks,

I am facing some issues with RadEditor Symbols - TM to be exact. Here is detailed scenario:

We are using RadEditor to let user compose and send emails. On adding TM symbol, it all works fine within RadEditor but when we send email, TM is not displayed in Outlook.

I read through couple of articles including https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/functionality/toolbars/dropdowns/symbols

and found that these symbols are set of unicode characters. So, is it really possible to successfully show TM to user instead of T while in Text mode in Outlook?

Snapshots attached for more details.

Any help please?

I'm using the Editor for a Notes field on a website. The notes field in the database table is being copied to a separate (Data Warehouse) database table for analysis. Is there any way to call a method in Telerik code via C#, that would return the notes without formatting?

Thanks

Hello,

I've got a system, where I want to check how often it run.
Now I've got 80 values with value 0 or 1 and Datetime.

Now I want to see how long it run in the last 24h.
X Axis is DateTime and Y Axis is 0 and 1

The first issue is, that it draws every Datetime value in the x axis, which really took long and wasnt really my target, cause 
through the wide of the line the user should see approximately how long it run.
If I change the BaseUnit to hour its fast, but all the smaller values get lost.

I added a picture what I am planning to do

Regards

I was using a textbox inside a RadGrid, to enter data in a column. This field was a list of donors. I did have a (rather large) lookup list of current donors (from a table) and I decided to try replacing the TextBox with a RadComboBox. A RadDropDown box, given the size of the list, would be rather clumsy, so a RadCombo Box made sense.

When I select a person from my dropdown, the batch edit block is closed. It looks like the postback wipes out the batch edit.

I'm trying to include a RadComboBox inside a RadGrid. When I select a person from my dropdown, the batch window is closed and the batch edit is reset

Am I going to have to scrap Batch Edit, or can I prevent the postback when an item is selected?

What are my options?

May I ask about How to keep the file after validation for Telerik RadAsync Upload?

I had put the Ajax settings, but its not work.

And I used Asp.net C# Web-Form 

Thanks for help with this.

I am passing a loaded datatable using a Session (Datatable) variable from another form to another form.  I then copy the Session (Datatable) variable to a local datatable and then bind this datatable  to a radgrid. 

When a cell changes value and the "Save Changes" is clicked.  All runs well but the entry.Value (newValue) is still showing old value.
changedRows[0][(string)entry.Key] = entry.Value;  

Also, I tried to loop through the grid in the same routine but I still see the old value as well.  I included the HTML code along with the update subroutine.
