Hello everyone,

    When I used Telerik. WinControls. DLL Update, I found that the new version was updated in the background, and the client could not update it again.

    For example, my original Telerik UI for WinForms 2018.2.621.40, now I update the Progress Control Panel in the background and change it to Telerik UI for

WinForms 2019.1.219.40. However, the client update will report an error, which appears: Telerik. WinControls. DLL access is denied.

Hi,

I have created a custom appointment edit form. In my main form I added a button to add new appointment to the scheduler.

When I click the button everything work fine.

The problem is :

When I click OK button the event AppointmentAdded was not trigger. But when I double click cell in scheduler or when I use the context menu to add appointment with my custom form when I click the OK the event AppointmentAdded is Triggered.

How can I add a button to add an appointment and when I click OK button on the EditAppointment form the event AppointmentAdded is triggered.

Thank you!

Hi,

I am developing a application using VirtualGrid which is used to drag and drop files and list the properties of the files. All is working fine. But when i expanded a row and dragged a new file, the whole grid was distorted. Please see the attached image for details.

Thanks well in advance.

Dear All,

I have a problem.

When I right-click anywhere in RadGridView, I don't want it to display any context menus.

What should I do？

Is this possible?

Best wishes

Hello, I am currently implenting the "Check All" functionality in group rows. Using this code that I've found here https://www.telerik.com/support/kb/reporting/details/check-all-functionality-in-group-rows

The "Check All" functionality itself works. But it's causing some trouble when I check more than one row individually. The error I'm getting is "The specified change is invalid." And it happens on this line "if ((bool)row.Cells["Include"].Value == false)"

Thanks in advance!

Hi

I use telerik 2018.1.220.40 and now I have problem with error:

System.ArgumentException: Parameter is not valid.
   at System.Drawing.Bitmap..ctor(Int32 width, Int32 height, PixelFormat format)

This error occurs several times per day. We need to restart application after this error because it doesn't respond. I don't create any Bitmap manual in my code and when I look at the error's path I think it's good to ask you about the reason of this error. Is it problem with Telerik or should I look for problem in my code?

Good morning friends,

Is there a simple possibility to change a certain theme color for all controls?

For example, there is the theme I'm using "visualStudio2012LightTheme1", the predominant color in various controls for this theme is blue, I would like to change that blue to a green.

Thank you very much for your attention!

Hi, 

I am using Telerik WinForms UI controls, Version - "2016.2.503.40" (Telerik.WinControls).

Facing a weird issue with GridView control version - "2016.2.503.40" (Telerik.WinControls.GridView)

When data or records are not available on the grid I am showing "No records available" text using below code lines,

myGridView.TableElement.Text = "No records available";

which works fine Attached screen "01_NoRecordsAvailable.JPG".

When some other window gets pop-up on this screen, "No records available" text disappears.

refer Attached screen "02_NoRecordsAvailable_Disappears.JPG".

No able to find out why the text is getting disappeared in such scenario.

Any help will be highly appreciated.
