Validators not Validating
Would anyone know why the validations on the page below wouldn't work. I am going through a book and learning asp.net and for some reason when I put in the last subroutine to insert the record the validation checks on the controls on the form no longer work.<%@ Import Namespace="System.Data.SqlClient" %><html><head><title>The Dorknozzle.com Intranet Site</title><script runat="server" language="VB">Dim objConn As New SQLConnection("Server=XXXXXXX; database=Dorknozzle; uid=XXXXXXX; Pwd=XXXXXXXX;")Dim objCmd As SQLCommandDim objRdr As SQLDataReader

Here is my situation - I've created a dynamic data website with one table.
The fields of this table are mostly varchar() not NULL, and all fields are defined with default value.
When trying to insert new row with empty values I get required validation on all fields.
What would be the best way to enable this validation only on some of these fields, while using default
values for the others?
For example empty string for varchar or 0 for int, etc
no in this case it will be add what error its return when u add. .Net DeveloperWeb Site Design and W...Web form and a gridview on the same page with data validators
I have a form where a user can submit a new customer and directly below that is a gridview where they can view the customer they just submited plus their other customers they have submited in the past. Now this gridview has the edit/update property so the user can modify their customer information. The whole idea is to have 1 single page where a user can do everything they need to without having to be linked to another page. On this page we can submit new customer info and view the status/info of existing customers and edit that info as needed.
So far that works fine. I can submit the new c...Page.Validate() not validating custom validators

I have a web user control that contains a textbox. I need to add some validation (like requiredfieldvalidator, comparevalidator, etc).
I would normally add the validator to my web user control by placing the validator next to my textbox. However, I need the validation message somewhere else on my web form, not near the user control.
So how would I associate a validation control on my web form with the text box inside my web user control? Can this be done; any alternatives out there?

If not, what are the alternatives?
Sure, it works fine. The only difference is that validation does not update when then change a field clientside... it does however update when the users pushes a submit button (after a round trip to the server)Pandora Tomorrow

In Internet Explorer, when you have a single textbox, a defaultbutton on the form, and a validator, by pressing enter in the textbox the first time (if it is invalid), the validator fires and the form doesn't submit. However, this sets __defaultFired to true, therefore the next time you click enter, even though the textbox is not valid, the page submits. In this case, the page_load executes and ispostback is true, however the button onclick server side function does not fire.

However, m...Validating States dropdownlist with all other validation controls on form?
I have States dropdownlist starts with "--" ListItem and 50 States. If user select "--" first ListItem, I need validate at client. Right now I am doing code behind side validation. But I have other controls on the form for validation, So I need to validate all at time. on submit button click.
Place a required field for states dropdown list and set the "intial value" property of required field validator to "--".
On Submit click validation is done.
Above is the solution if i am not misunderstood you.
