I have the following ASP page:
<asp:Content ID="Content2" ContentPlaceHolderID="ShellContent" runat="server">
<form runat="server" id="AddNewNoteForm" method="post"">
<fieldset id="NoteContainer">
<legend>Add New Note</legend>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
<div class="ctrlHolder">
<asp:Label ID="LabelNoteDate" runat="server" Text="Note Date"
AssociatedControlID="NoteDateTextBox"></asp:Label>
<asp:TextBox ID="NoteDateTextBox" runat="server" class="textInput"
CausesValidation="True" ></asp:TextBox>
<asp:CustomValidator
ID="CustomValidator1"
runat="server"
ErrorMessage="CustomValidator"
ControlToValidate="NoteDateTextBox"
OnServerValidate="CustomValidator1_ServerValidate"
Display="Dynamic"
>*</asp:CustomValidator>
</div>
<div class="ctrlHolder">
<asp:Label ID="LabelNoteText" AssociatedControlID="NoteTextTextBox" runat="server" Text="Note"></asp:Label>
<asp:TextBox ID="NoteTextTextBox" runat="server" Height="102px"
TextMode="MultiLine" class="textInput" ></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ErrorMessage="Note Text is Required" ControlToValidate="NoteTextTextBox">*</asp:RequiredFieldValidator>
</div>
<div class="buttonHolder">
<asp:Button ID="OkButton" runat="server" Text="
Add New Note"
CssClass="primaryAction" onclick="OkButton_Click"/>
<asp:HyperLink ID="HyperLink1" runat="server">Cancel</asp:HyperLink>
</div>
</fieldset>
</form>
</asp:Content>
and the following code behind for the CustomValidator1_ServerValidate() method:
protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
{
if (string.IsNullOrEmpty(args.Value.Trim()))
{
args.IsValid = false;
CustomValidator1.ErrorMessage = "Note Date is Required!";
return;
}
DateTime testDate;
if (DateTime.TryParse(args.Value, out testDate))
{
args.IsValid = true;
CustomValidator1.ErrorMessage = "Invalid Date!";
}
}
It never seems to fail validation no matter what I put in the text box...
Should mention this is ASP.NET 2.0
