How are you?

I am starting to use Devexpress components, and would like to implement Dxerrorprovider, which in my case, if the value of the text box is null, or empty, would be displayed the error icon next.

So I got into the Devexpress help: https://documentation.devexpress.com/#CoreLibraries/DevExpressXtraEditorsDXErrorProviderErrorTypeEnumtopic

I don’t understand the code itself, so I understood the bindingSource makes the link between my textbox and my data source, which in this case is empty.

then I assign this link to Dxerrorprovider, right?

then comes a myrecord class, for what purpose? would be for when to put the mouse on top appear the error message?
