Web Forms :: Validation Summary Message Box Does Not Pop-up For A Required Field Validator
May 10, 2010i am working on web-form for which I have set the validation summary showmessagebox = "true".
I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box.
i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does
not show me the text boxes...

Web Forms :: Created Some Required Field Validators And A Validation Summary Control?
Feb 24, 2011I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.

View 22 RepliesInput Validation - How To Turn Off .NET Required Field Validator "lost Focus" Behaviour
Jun 23, 2010I have some code where I need two separate required field validators for one control, both in separate validation groups which are then validated by two separate buttons.This approach works well when the buttons are clicked but both validators show if I enter a value in the textbox and then remove it.
Is there a way to turn this"lost focus" validation off? I only need it to validate when the buttons are clicked.
EDIT,Unfortunately, if I set EnableClientScript=false then I dont have any client notifications. What I want is for the dynamic error message to show (effectivly in the OnClientClick event of the button) but not the "lost focus" of the textbox.Is there some way I can disable or "unhook" the lostfocus client event?
EDIT,A combination dDejan's answer and womp's answeer here sorted the problem perfectly.
My final code looks like this (for anyone else with a similar situation)...
Javascript...
<script type="text/javascript">
$(document).ready(function() { [code]....
So, now there is no validation until a user clicks either the "Get Email Confirmation Code" button or the "Register" button. If they click the "Get Email Confirmation Code" button all of the controls validate apart from the textbox where the user is to input the email validation code and we only see one validator message.
If they click the "Register" Button then all of the controls validate and we only see one validation message.If either button is pressed, the user goes back, adds and then removes some text then we only see one validator. Before this change you used to see both messages saying the same thing.
Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?
Apr 1, 2011I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

Web Forms :: Required Field Validator Not Catching Empty Field?
Feb 3, 2010I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
