CustomValidator issue

[jmclej]

Here is what I have :

<asp:templatecolumn HeaderText="HrBegin">
<itemtemplate>
<asp:Label id="lblHrBegin" runat="server" Text='<%#
DataBinder.Eval(Container.DataItem, "HrBegin") %>' Width="100%">
</asp:label>
</itemtemplate>
<footertemplate>
<asp:textbox id="tbHrBeginInsert" runat="server"
Width="100%"></asp:textbox>
<asp:CustomValidator id="Customvalidator1"
ControlToValidate="tbHrBeginInsert" OnServerValidate="ServerValidation"
Display="None" runat="server"></asp:CustomValidator>
</footertemplate>
<edititemtemplate>
<asp:textbox id="tbHrBegin" runat="server" Text='<%#
DataBinder.Eval(Container, "DataItem.HrBegin") %>'
Width="100%"></asp:textbox>
<asp:CustomValidator id="Customvalidator2"
ControlToValidate="tbHrBegin" OnServerValidate="ServerValidation"
Display="None" runat="server"></asp:CustomValidator>
</edititemtemplate>
</asp:templatecolumn>


Code Behind:

void ServerValidation(object source, ServerValidateEventArgs args) {
try
{
Regex r = new
Regex("(([0-1][0-9])|(2[0-3]))[0-5][0-9])[0-5][0-9])"); //Only
allow "02:03:04"
Match m = r.Match(args.Value);
// Test whether the value entered into the text box is in a correct
hour format.
if (m.Success)
args.IsValid = true;
else
args.IsValid = false;
}
catch(Exception ex)
{
args.IsValid = false;
}
}

I put the ServerValidation() function on the code behind because I
thought that this was the way of doing server-side validation. But it
actually works only if I put this function inside a script block on the
aspx page, which looks like then client-side validation, no? Maybe I
need to add something in the InitializeComponent() method?
But anyway, even like this there is still something that is not good.
It's that I get all the time the same text to be validated, that is the
content of my itemtemplate. What should I do to make ServerValidation()
to test the new data entered in the textbox tbHrBeginInsert or
tbHrBegin?
Thank you very much for your help.

Not the answer to your question, but since you are only doing a RegEx
test, why don't you use the RegularExpression Validator?

euuuuhhh because I hadn't seen it actually :-( Thank you!
I then changed it, but still, I get the same problem, that is the value
evaluated is not the one I enter in the edititemtemplate, but only the
inital value set in itemtemplate.
Any idea someone?
Cheers,

Didn't see that you are doing this in a DataGrid (I assume).
Here is a nice example with source code (view source link)

Hope that helps
