Dear Kendo Experts,

I hope this message finds you well.

I am currently facing an issue with custom validation error messages in a Kendo Grid. I have created a sample Dojo link to demonstrate the problem:

https://dojo.telerik.com/IgOLaREr

I have a kendo grid with a custom editor (dropdownlist) for a column (Category). 

In the provided Kendo Grid, I have two columns: "ProductName" and "Category". While "ProductName" has a default editor, "Category" has a custom editor (dropdown list).

I have defined custom validation error messages for both columns in the schema. However, the custom validation error message for the "Category" column does not appear when validation fails, unlike the "ProductName" column. Please refer the below screenshot.

Could you please assist me in resolving this issue? I would like the custom validation error message for the "Category" column to be displayed when validation fails, similar to the "ProductName" column.

Thank you very much for your time and assistance. I look forward to hearing from you soon.

Best regards,

Varun Shridhar.

In radscheduleview, added multiple resources and grouping based on custom resourceview, Also, added custom datatemplate for GroupHeaderContentTemplateselector. 

In the below yellow hightlighted place , (group header ) need to add Resource related information for the day in weekview. But couldnot  get exact datacontext of the group header while switching between dates,  Only able to get IResource from Groupheaderdescriptions. In IResource having only few properties for cusomization. 

So, could not able to bind any property to Group header template. Please suggest on this?

This has happened more than a few times in the last 8 weeks. I hope we can resolve once and for all.

According to Google, they are going to deprecate Third-Party Cookies.

A customer is using telerik controls invoking libraries using CDN. 

They found this cookies related to telerik marked as affected by this deprecation.

How can we avoid this situation?

thank you for your help

I am currently experiencing an I/O exception when trying to export the RadDocument to a byte array using the Telerik.Windows.Documents.FormatProviders.Pdf.PdfFormatProvider.

Here is a code snippet of how am I using the Provider:

PdfFormatProvider pdfProvider = new PdfFormatProvider();

_printReportByteArray = pdfProvider.Export(_printReportDocument);

using (var memoryStream = new MemoryStream(_printReportByteArray))
{
    this.PrintReportViewer.DocumentSource = new PdfDocumentSource(memoryStream);
}

The exception occurs at

pdfProvider.Export(_printReportDocument)

It appears that the provider is trying to load the font file from the Windows directory, but for some reason this particular file is causing the exception randomly on certain machines (not on all machines). I would like to know if there is a way to resolve this issue. Like loading the font file into the memory instead of relying on the Windows directory.

Note: the font file does exist at the provided path location, and is not missing.

Here is the full exception message:

Dear Telerik Community,

I hope this message finds you well. I am reaching out to seek assistance with an issue I am encountering in my Telerik WinForms application.

Problem Description: I have designed a Windows Form using Telerik controls, which includes a RadForm containing a RadGroupBox with various Telerik controls such as RadTextBoxes, RadDropDownList, and RadButton. However, when I run the application, I notice that the dimensions of the controls are automatically increasing, leading to inconsistent layout and undesired vertical spacing between controls. Snapshot for reference attached..

Steps Taken:

1. Added RadForm to the project.
2. Included a RadGroupBox within the RadForm.
3. Added RadTextBoxes, RadDropDownList, and RadButton to the RadGroupBox.

Expected Solution: I am seeking guidance on the settings or configurations that need to be implemented to ensure that the layout of the form remains consistent and does not automatically resize the controls.
