Validator inside Server control
<p>I have a server control that inherits from TableRow and INamingContainer.
I override the CreateChildControls and add three cells, in the first one I put a label, in the second one I put a textbox (lets call it A) with autopostback true and causevalidation true, a required validator and a range validator, in the third one another label.
Additionally, I have another textbox (B) with autopostback true and cause validation true, but in the webform, not in the server control.</p>

<p>When I write a <em>valid</em> value in the textbox A, the postback occurs but the rangevalidator is displayed. If after that, I change the value of the textbox B, the rangevalidator of the textbox A is not displayed and everything works as I expect.</p>

<p>What is wrong?</p>
