Hi Astemir,
Thank you for your interest in Syncfusion products.
Currently we have not implemented the feature 'Validation support for PropertyGrid'. We would like to inform you that we have logged this as a feature request in our database. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. A support incident to track the status of this feature has been created under your account. Please log on to our support website to check for further updates

In the workaround sample, we have used SfMaskedEdit as CustomEditor in the PropertyGrid. For the SfMaskedEdit control, we have set the ValidationMode as KeyPress and Masked the Input to allow only characters and numbers and the first input should be a character. Please find the workaround sample in the following link.
Sample:
PropertyGrid_119059.zipCould you please let us know if our workaround satisfies your requirements and if you require further assistance on this.
