Hi Аdel,

To achieve the desired functionality you could try setting the Button.ValidationGroup property to "save" (instead of "Save"). Also you need to set Button.CausesValidation property to true.
Additionally I am sending you a simple example, based on your code, which demonstrates how to achieve the desired functionality.

I hoe this helps.

All the best,
