ASP.NET: ValidationSummary doesn't display any contents

I'm trying to figure out how the heck the validation summary control of ASP.NET (3.5 I think) works.

<asp:ValidationSummary ID="vldSummary" runat="server" DisplayMode="BulletList" 
  CssClass="error" EnableClientScript="true" />
<asp:RequiredFieldValidator ID="vldSubject" ControlToValidate="txtSubject"
  EnableClientScript="false" Text="You must enter a subject." runat="server" />
<asp:RequiredFieldValidator ID="vldMessage" ControlToValidate="txtMessage"
  EnableClientScript="false" runat="server" Text="You must enter a message." />

It seems that no matter what I do, the validation summary remains empty (but is rendered) and the errors are only displayed at the position of each respective validator.

What am I doing wrong?

Set the ErrorMessage property on the RequiredFieldValidators, not the Text property.

<asp:RequiredFieldValidator ID="vldSubject" ControlToValidate="txtSubject" EnableClientScript="false" ErrorMessage="You must enter a subject." runat="server" />
<asp:RequiredFieldValidator ID="vldMessage" ControlToValidate="txtMessage"  EnableClientScript="false" runat="server" ErrorMessage="You must enter a message." />

Text property's value is what is displayed beside the control. You need to set the ErrorMessage property of the validators to control what is shown in the summary.

You want to set the ErrorMessage property on your validation controls. This text will be displayed by the ValidationSummary control.

Try:

<asp:ValidationSummary ID="vldSummary" runat="server" DisplayMode="BulletList" CssClass="error" EnableClientScript="true" />
<asp:RequiredFieldValidator ID="vldSubject" ControlToValidate="txtSubject" EnableClientScript="false" ErrorMessage="You must enter a subject." runat="server" />
<asp:RequiredFieldValidator ID="vldMessage" ControlToValidate="txtMessage" EnableClientScript="false" runat="server" ErrorMessage="You must enter a message." />
