how to reset input field after validation fails?
<p>I have a validator for a date input field. If the input is not in the MM/DD/YYYY format then it should throw an error and <strong>clear the input</strong>. I have tried Text="" property, but that doesn't work. And setFocusOnError is only working once.If I hit tab twice the field is losing foucs . Any ideas?</p>

<pre><code>&lt;asp:RegularExpressionValidator ID="startDateValidator" Display="Dynamic"
                   ControlToValidate="dateStartDate" ValidationExpression="([0-9]|1[012])[/]([0-9]|[12][0-9]|3[01])[/](19|20)\d\d" 
                   ErrorMessage="Start Date should be in MM/DD/YYYY format" runat="server" SetFocusOnError="true" 
                   /&gt;
</code></pre>

<p><strong>EDIT:</strong> I want to know if this is possible using asp's validator controls.And why SetFocusOnError is not working as it's supposed to? </p>
