    text
    copied!<p>I have been trying to use regex but I cant seem to get it to work. I'm trying to use regex with the asp.net <code>RegularExpressionValidator</code>. What I want it to do is to basically disallow leading and trailing spaces only.</p> <p>So,</p> <pre><code>"hello " // would not work. "hello my name is" // would work. </code></pre> <p>But in all my attempts it says bad input no matter what I put in.</p> <p>Here is what I used:</p> <pre><code>^\s[a-z]+\s$ </code></pre> <p>Can someone please provide one that works?</p> <p>And also, what does it mean when someone says the regex returned a match?</p> <p>Edit:</p> <p>I have tried all the solutions in the thread and none of them work for me. Maybe it is something else wrong and not the regex? Heres is the relevant code:</p> <pre><code> &lt;InsertItemTemplate&gt; &lt;asp:TextBox CssClass="tbUpdateSummary" TextMode="MultiLine" Text='&lt;%# Bind("updateSummary") %&gt;' ID="tbUpdateSummaryInsert" runat="server"&gt;&lt;/asp:TextBox&gt; &lt;asp:RequiredFieldValidator ID="valUpdateSummaryInsert1" runat="server" Display="None" ControlToValidate="tbUpdateSummaryInsert" ErrorMessage="Update summary must not be empty."&gt; &lt;/asp:RequiredFieldValidator&gt; &lt;asp:RegularExpressionValidator ValidationExpression="^\s+|\s$" ID="valUpdateSummaryEdit2" runat="server" Display="None" ControlToValidate="tbUpdateSummaryInsert" ErrorMessage="Update summary must not contain leading or trailing spaces."&gt; &lt;/asp:RegularExpressionValidator&gt; &lt;%--Put c# code to validate length (max 200)--%&gt; &lt;asp:CustomValidator&gt;&lt;/asp:CustomValidator&gt; &lt;/InsertItemTemplate&gt; </code></pre> <p>^[^\s].+[^\s]$ &lt;======= This one actually works!! </p>
