Custom validator

[diacoboss]

Hi guys, I have a small problem, hope u would help me ! I'm tryin to use a custom validator on a Textbox ! Look : * The code behind now protected void first_CV_ServerValidate(object source, ServerValidateEventArgs args) { if (TextBox2.Text == "") { args.IsValid = false; } else { args.IsValid = true; } } Basically, I hoped to see a message when the Textbox is empty! But nothin happen when Click on my submit button Please help me

You either need to replace the CustomValidator with a RequiredFieldValidator (if you don't need any other custom logic) or set the ValidateEmptyText property of the CustomValidator to true, to force the validator to operate on empty strings. By default, the CustomValidator won't validate if the control is empty.

I can't use a RequiredFieldValidator A custom validor is necessary. By setting the ValidateEmptyText I thing quite good. But In the same Page I have RequiredFieldValidator RegularFieldValidator and ValidationSummary and others controls. When I click on the submit button I have a messageBox telling me I forgot sum requiredFields or anytthing like dat. But no reference about the field concerned by the Custom Validator in this same MessageBox! So now I am asking can I show in a messageBox the message error of my CustomValidator ? thx (sorry for my english, I'm French)
