asp.net building controls:
This may or may not be possible, so please let me know either way. I'm just attempting to do something fancy and I haven't been able to find any documentation on this specific issue anywhere. I have a custom validator which runs only on the server side. It "attaches" itself to a label to display one error message at a time. So, if multiple validation controls fail, it only displays the first one in line. Once corrected, it will display the second one. And so on. So far, it's working well both alone and in multiple instances. Because it's designed to only display one message, allowing the page to validate the other controls is overkill. What I'd like to do is skip the other validators if one of them fails. At this point, I'm able to trap and exit the validation within the custom control's ServerValidate function, but I'm having a problem skipping it on the page itself. If the ServerValidate function is added to the Page, it runs even if it's been told to exit from within the custom control. Is there a command (or workaround) that will allow me to override or exit the event in the page's code-behind from within the custom control? [Custom Control] Private Sub CustomServerValidator_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles Me.ServerValidate For Each item As CustomServerValidator In Page.Validators If Not item.IsValid Then Exit Sub End If Next If Me.ValidateEmptyText AndAlso args.Value = "" Then args.IsValid = False CType(Page.FindControl(Me.ErrorLabel), Label).Text = Me.ErrorMessage End If End Sub End Class [Page] Protected Sub CustomServerValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomServerValidator1.ServerValidate MsgBox("I ran anyway!") End Sub Protected Sub CustomServerValidator2_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomServerValidator2.ServerValidate MsgBox("I ran anyway!") End Sub
Wow, did I stump the group or did I simply confuse everyone with my explanation of the problem? lol Bueller? Bueller?
