Is Custom validation firing?

[stephenk1973]

I have tried to create my first custom validation on a text box using funciton on the net. The text box is to be passed to a stored procedure.

Validation always returns false, i'm not sure if the funciton is being called at all. Validation occurs when you press 'enter', and it always seem to pass the variable to the procedure regradless.

Any other validation ( required, range etc) all work fine, where am i going astray or is there a good 101 on custom validation.

Thanks

Stephen


Function IsValidField(ByVal stext)
{
var ValidChars = "0123456789, ";
var IsGood=true;
var Char;

alert(document.Form1.textbox1.Value);

for (i = 0; i < sText.length && IsNumber == true; i++)
{
Char = sText.charAt(i);
if (ValidChars.indexOf(Char) == -1)
{
IsGood = false;
}
}
return IsGood;

}


<asp:TextBox ID="TextBox1"
runat="server">
</asp:TextBox>
<asp:CustomValidator
ID="CustomValidator1"
runat="server"
ControlToValidate="TextBox1"
ErrorMessage="CustomValidator"
ClientValidationFunction="IsValidField">*
</asp:CustomValidator>

Have you tried debugging the project and stepping through the code? That will tell you if it has been called...

Also, a quick tets would be to put an "alert" box in your function.

I am not quite sure.

- The IsValidField get an argument but i don't see where you assign it.
- I think that the javascript funtion (client side) for validation purpose must be like: function a_name(sender, e) { ... }.

There is an alternative way. Why do you want to do the validatin on the client side? (speed?)

- Double click on the CustomValidator and see the events that it can handle.
- USe of regEx ?

noticed a couple of things:

this:
Function IsValidField(ByVal stext)

should be:
function IsValidField(sender,args)


1. ByVal is NOT a javascript function
2. CustomValidator functions will take 2 parameters (in ASP.NET 1.1 atleast)...
