I'm having issues with asp.net's field validators taking up space on my page. I've searched around, and documentation says to use Display="Dynamic" to keep the validators from taking up space. When I use this however, the error messages are always displayed.
What am I doing wrong?
I just want the error messages to display when the user either clicks the "Save" button, or loses focus on a textbox. And I don't want the validators to take up space.
<p>Please enter a new email:</p>
<asp:TextBox runat="server" MaxLength="255" ID="TextBoxEmail" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1"
ValidationGgroup="Email"
ErrorMessage="Please enter an email"
ControlToValidate="TextBoxEmail" runat="server"></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2"
ValidationGroup="Email"
ControlToValidate="TextBoxEmail"
ErrorMessage="Please enter valid email"
runat="server"
ValidationExpression="\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*" />
<p>Please re-enter your email:</p>
<asp:TextBox runat="server" ID="TextBoxEmail2" />
<asp:LinkButton ValidationGroup="Email" runat="server" Text="Save" OnClick="linkbuttonSave_Click" />
Only thing I notice in your code is you have a typo in ValidationGgroup="Email". It should be ValidationGroup="Email"
Other than that, Display="Dynamic" works for me.
After clicking, submit button -
<p>
Please enter a new email:</p>
<asp:TextBox runat="server" MaxLength="255" ID="TextBoxEmail" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ValidationGroup="Email"
ErrorMessage="Please enter an email" ControlToValidate="TextBoxEmail" runat="server"
Display="Dynamic"></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" ValidationGroup="Email"
ControlToValidate="TextBoxEmail" ErrorMessage="Please enter valid email" runat="server"
ValidationExpression="\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*" Display="Dynamic" />
<p>
Please re-enter your email:</p>
<asp:TextBox runat="server" ID="TextBoxEmail2" />
<asp:CompareValidator ID="PasswordCompare" runat="server" ControlToCompare="TextBoxEmail"
ControlToValidate="TextBoxEmail2" CssClass="failureNotification" Display="Dynamic"
ErrorMessage="Must match." ValidationGroup="Email"></asp:CompareValidator>
<asp:RequiredFieldValidator ID="RequiredFieldValidator3" ValidationGroup="Email"
ErrorMessage="Please enter an confirm email" ControlToValidate="TextBoxEmail2" runat="server"
Display="Dynamic"></asp:RequiredFieldValidator>
<asp:LinkButton ID="LinkButton1" ValidationGroup="Email" runat="server" Text="Save"
OnClick="linkbuttonSave_Click" />
You can set the property Display to "Dynamic" or "none", the second one will cause the Error message to be displayed only in the validation summary.
I got it to work great by deleting the "ValidationGroup=.." . Havent looked what up what this does but it works great without it and not sure why it would be needed (given the validator controls have the control id of the email textbox)

I have two Validation Groups on my page, called "login" and "register". Each group has its own ValidationSummary control and there a number of RequiredFieldValidators too. The problem I have is that the form is validating both groups instead of just the one.
Here is the code (I have omitted a lot of HTML to simplify):
<div id="divRegisterBox">
<asp:ValidationSummary ID="ValidationSummary1" runat="server" ValidationGroup="register" />
<asp:TextBox ID="tbRegisterEmail" runat="server" CssClass="form-control" placeholder="Required" ValidationGroup="register" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="tbRegisterEmail" runat="server" Text="" ErrorMessage="Please enter your email address." ValidationGroup="register" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" CssClass="errorMsg" ControlToValidate="tbRegisterEmail" runat="server" Text="" ErrorMessage="Please enter a valid email address." ValidationExpression="^([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)$" ValidationGroup="register" />
<asp:TextBox ID="tbRegisterPassword" name="result-password" runat="server" CssClass="form-control" placeholder="Required" TextMode="Password" ValidationGroup="register" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" CssClass="errorMsg" ControlToValidate="tbRegisterPassword" runat="server" Text="" ErrorMessage="Please enter your password." ValidationGroup="register" />
<asp:Button ID="btnMobileRegister" runat="server" Text="Register" OnClick="btnMobileRegister_Click" ValidationGroup="register" />
</div>
<div id="divLoginBox">
<asp:ValidationSummary ID="ValidationSummary2" runat="server" ValidationGroup="login" />
<asp:TextBox CssClass="form-control" name="result-email" ID="tbResultEmail" placeholder="Required" runat="server" ValidationGroup="login"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator3" ControlToValidate="tbResultEmail" runat="server" Text="" ErrorMessage="Please enter your email address." ValidationGroup="login" CssClass="errorMsg" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" CssClass="errorMsg" ControlToValidate="tbResultEmail" runat="server" Text="" ErrorMessage="Please enter a valid email address." ValidationExpression="^([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)$" ValidationGroup="login" />
<asp:TextBox CssClass="form-control" name="result-password" ID="tbResultPassword" placeholder="Required" TextMode="Password" runat="server" ValidationGroup="login"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator4" CssClass="errorMsg" ControlToValidate="tbResultPassword" runat="server" Text="" ErrorMessage="Please enter your password." ValidationGroup="login" />
<asp:Button ID="btnLoginMobile" runat="server" CssClass="btn btn-primary btn-block" Text="Login" OnClientClick="return MobileLoginSubmit();" ValidationGroup="login" OnClick="btnLoginMobile_Click" />
</div>
When I click either of the Button controls, the ValidationSummary controls show the validation messages for ALL validation controls on the page. It is as if they were all part of the same validation group.
I have tried adding CausesValidation="true" and "false" to the Buttons but it seemed to have no effect.
On your CodeBehind, you could do something like...
Page.Validate("register");
if (Page.IsValid)
{
//Keep calm and carry on
}
else
{
foreach (BaseValidator invalidField in validators)
{
//Do something with the invalid fields
}
}
That way, you're only validating that group that you specify.
Makes sense?
Your issue is Display="None".
In your divRegisterBox div, your validators all have Display="None", but your validators in your divLoginBox div do not.
Display="None" will not display the message inline. What you are seeing when you click the login button is not that both summaries are showing, but that the same error messages are being displayed in two different ways.
I'm trying to use two validators for the same control as shown in below code
<asp:TextBox runat="server" ID="tbEmail" placeholder="Enter email" class="form-control" required=""></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="tbEmail" ValidationGroup="DRF" Display="Dynamic"
ValidationExpression="\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>
<asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ControlToValidate="tbEmail" ValidationGroup="DRF" Display="Dynamic"></asp:RequiredFieldValidator>
But the problem is the second validator works but the first validator doesnot. I tried flipping them but same thing happens.
What I have to do to make both of them work at the same time ?
Can you help me in this?
Add an ErrorMessage attribute to the regex validator like so:
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="tbEmail" ValidationGroup="DRF" Display="Dynamic"
ValidationExpression="\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*" ErrorMessage="Please enter a valid email address"></asp:RegularExpressionValidator>
I've seen a variety of questions here that are very close to this issue but none which seem to fit this specific scenario.
Description:
I have ID and Password fields with a Log On button in the Master page. These are in the "LoginValidationGroup" and they work fine.
Now, in the Default.aspx, I have an email TextBox and submit button that are in the "NotifyMeValidation" group, and they also work, BUT not if you hit the enter key rather than the submit button. The Submit button works fine - Enter key ... not so much.
The Enter key causes the validation to occur on the LoginValidationGroup, even though the TextBox is set to CausesValidation="true", and it is in the NotifyMeValidation group.
I guarantee people are going to enter an email in that box and hit Enter. I would!!! And when they do, they're going to see a callout balloon at the top telling them the User ID is required.
What's my error here? If I need to post the actual code I can do so.
Actually, let me just go ahead and do that.
From the Default.aspx:
<asp:RequiredFieldValidator
runat="server"
ValidationGroup="NotifyMeValidation"
ID="EmailRequiredValidator"
ControlToValidate="SenderEmailTextBox"
ErrorMessage="Email is Required"
Display="None" />

<asp:TextBox ID="SenderEmailTextBox" runat="server" ValidationGroup="NotifyMeValidation" Width="350" BackColor="#cccccc" CausesValidation="true"></asp:TextBox>
<br /><br />
<asp:Button ID="SubmitButton" runat="server" ValidationGroup="NotifyMeValidation" EnableViewState="false" CssClass="submit" Text="Send" CausesValidation="true" OnClick="btnSubmit_Click" />
From the Master page:
<asp:Label CssClass="LoginHeading" ID="UserNameLabel" runat="server" AssociatedControlID="UserNameTextbox">UserName: </asp:Label>
<asp:TextBox CssClass="LoginTextBox" ID="UserNameTextbox" runat="server" ValidationGroup="LoginValidation" CausesValidation="True"></asp:TextBox>
<asp:Label CssClass="LoginHeading" ID="PasswordLabel" runat="server" AssociatedControlID="PasswordTextbox">Password: </asp:Label>
<asp:TextBox CssClass="LoginTextBox" ID="PasswordTextBox" runat="server" TextMode="Password" ValidationGroup="LoginValidation" CausesValidation="True"></asp:TextBox>
<asp:Button CssClass="LoginHeading" ID="LoginButton" runat="server" Text="Button" CommandName="Login" ValidationGroup="LoginValidation" CausesValidation="True" onclick="LoginButton_Click" />
And the Master page validators...

Try adding an <asp:Panel> around each set of controls and setting the DefaultButton property to the ID of the button you want to click when the users hits Enter.
Just to explain what is happening here, the aspx's default button is being fired when you press enter on the textbox. To handle this you could you could fire some jQuery code when the enter key is clicked on the textbox, this code will then perform the click on the specific button that you require. Check this
I have following HTML structure :
<asp:TextBox ID="txtFrom" class="textBox js-min" runat="server" />
<asp:RequiredFieldValidator ID="strtDtValidator" ControlToValidate="txtFrom" runat="server" ErrorMessage="Please enter a date." Text="*" Display="Dynamic" CssClass="required" EnableClientScript="true"></asp:RequiredFieldValidator>
<span class="label" id=""> End:</span>
<asp:TextBox ID="txtTo" class="textBox" runat="server" />
<asp:RequiredFieldValidator ID="endDtValidator" ControlToValidate="txtTo" runat="server" ErrorMessage="Please enter a date." Text="*" Display="Dynamic" CssClass="required" EnableClientScript="true"></asp:RequiredFieldValidator>
It is displaying star both "*" symbol after the last textbox. How to place them correctly?
if you would like to see the "Please enter a date." text next to the TextBox then put Text="Please enter a date." for the RequiredFieldValidator. TheErrorMessage property is used if you have a ValidationSummary control, which will list all the errors.
I'm trying to figure out how the heck the validation summary control of ASP.NET (3.5 I think) works.
<asp:ValidationSummary ID="vldSummary" runat="server" DisplayMode="BulletList"
CssClass="error" EnableClientScript="true" />
<asp:RequiredFieldValidator ID="vldSubject" ControlToValidate="txtSubject"
EnableClientScript="false" Text="You must enter a subject." runat="server" />
<asp:RequiredFieldValidator ID="vldMessage" ControlToValidate="txtMessage"
EnableClientScript="false" runat="server" Text="You must enter a message." />
It seems that no matter what I do, the validation summary remains empty (but is rendered) and the errors are only displayed at the position of each respective validator.
What am I doing wrong?
Text property's value is what is displayed beside the control. You need to set the ErrorMessage property of the validators to control what is shown in the summary.
You want to set the ErrorMessage property on your validation controls. This text will be displayed by the ValidationSummary control.
Try:
<asp:ValidationSummary ID="vldSummary" runat="server" DisplayMode="BulletList" CssClass="error" EnableClientScript="true" />
<asp:RequiredFieldValidator ID="vldSubject" ControlToValidate="txtSubject" EnableClientScript="false" ErrorMessage="You must enter a subject." runat="server" />
<asp:RequiredFieldValidator ID="vldMessage" ControlToValidate="txtMessage" EnableClientScript="false" runat="server" ErrorMessage="You must enter a message." />
Set the ErrorMessage property on the RequiredFieldValidators, not the Text property.
<asp:RequiredFieldValidator ID="vldSubject" ControlToValidate="txtSubject" EnableClientScript="false" ErrorMessage="You must enter a subject." runat="server" />
<asp:RequiredFieldValidator ID="vldMessage" ControlToValidate="txtMessage" EnableClientScript="false" runat="server" ErrorMessage="You must enter a message." />
