Passing additional arguments into the OnClick event handler of a LinkButton using Javascript
<p>I have a ASP.NET Website, where, in a GridView item template, automatically populated by a LinqDataSource, there is a LinkButton defined as follows:</p>

<pre><code>&lt;asp:LinkButton ID="RemoveLinkButton" runat="server" CommandName="Remove"
                CommandArgument='&lt;%# DataBinder.GetPropertyValue(GetDataItem(), "Id")%&gt;'                                 
                OnCommand="removeVeto_OnClick"
                OnClientClick='return confirm("Are you sure?");'
                Text="Remove Entry" /&gt;
</code></pre>

<p>This works fine. Whenever the Button is Clicked, a confirmation dialog is displayed.</p>

<p>What I am trying to do now, is to allow the user to enter a reason for the removal, and pass this on the the OnClick event handler. How would I do this? 
I tried <code>OnClientClick='return prompt("Enter your reason!");'</code>, but, of course, that did not work =)</p>
