I have several required fields and regex's on my form. The validation is fired on a button click. When the button is clicked, the error messages are showing where the asp:RequiredField are declared and not in the validation summary. Here is my code:
Validation Summary:
<asp:ValidationSummary id="mySummary" DisplayMode="List" HeaderText="Error:" EnableClientScript="true" ShowSummary="true" runat="server" ValidationGroup="valGroup" />
Required Fields/Regex:
<!-- Required -->
<asp:RequiredFieldValidator ID="reqField1" ControlToValidate="txtSomething" ErrorMessage="Something is required" runat="server" Display="Static" InitialValue="" ValidationGroup="valGroup" />
<!-- Regex -->
<asp:RegularExpressionValidator runat="server" id="regexField1" ControlToValidate="txtSomething"
ErrorMessage="Something in the wrong format." ValidationExpression="^([\w-]+(?:\.[\w-]+)*)#((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$" ValidationGroup="valGroup">
</asp:RegularExpressionValidator>
Button:
<asp:LinkButton ID="btnValidate" runat="server" CausesValidation="True" ValidationGroup="valGroup" >Validate</asp:LinkButton>
Any suggestions?
It's hard to tell from this, as it does look like it's setup correctly to me. The only way to debug is to check the Page.Validators collection, find the validators in there, and ensure IsValid is false for those guys. All the ValidationSummary does is check this collection, and for any with a matching validation group, if the IsValid property is false, adds it to the list that's rendered out.

I am using two asp.net validation controls 1. RequiredFieldValidator & 2. RegularExpressionValidator for my password textbox to validate the user input and set its display property to none so that valiadation message will only get displayed in validationsummary control.
when I click on submit button the validation get displayed as expected but when I use SetFocusOnError as true for both validators sometimes the validation message doesn't get refreshed for ex. if there is no text entered in the text box and click on submit button it display required field validation message but when enter any text and click on submit button it still display required field validation instead of RegularExpressionValidator validation message but when click submit button next time it propertly display
RegularExpressionValidator validation message
<asp:TextBox ID="txtPass" CssClass="form-control" runat="server" TextMode="Password"
meta:resourcekey="txtPassResource1" autocomplete="off"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvPass" runat="server" SetFocusOnError="true" ControlToValidate="txtPass"
Display="None" ErrorMessage="Enter Password" ValidationGroup="submit"
meta:resourcekey="rfvPassResource1"></asp:RequiredFieldValidator>
<div class="password_error" style="width:auto;">

<div class="col-md-offset-6">
<asp:Button ID="btnSubmit" runat="server" OnClientClick="return ValidatePage();" CssClass="btn btn-primary" Text="Submit" OnClick="btnSubmit_Click"
ValidationGroup="submit" meta:resourcekey="btnSubmitResource1" />
</div>
Please do test it again as when I reviewed and tested your code, it worked perfectly fine.
The error showed as per validation. If still some anomaly happens, do show that exact code.
This is the issue I have going right now with validation controls and I simply can't find answer anywhere for it.
I currently have a required field validator watching a listbox. The validator's initial value property is set to "None". The first item in the listbox's value is also set to "None", thus forcing the user to change the selection. However I don't want the validation to show on the selected index change, I want it to show after a button press. So I changed the validation group of the validator and the button to "final" however the validator still shows on selected index changed without the button being pressed.
My code on the validator:
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ErrorMessage="Please Select an Incident" ControlToValidate="lstIncidents"
ValidationGroup="final" CssClass="style3" InitialValue="None" Display="Dynamic">
</asp:RequiredFieldValidator>
My Code on the Submit Button:
<asp:Button ID="btnSubmit" runat="server" Text="Submit" ValidationGroup="final"
Enabled="False" />
Anyone see what might be wrong here?
Thanks in advance!
Set the validator's EnableClientScript to false (default is true):
<asp:RequiredFieldValidator EnableClientScript="False" ID="RequiredFieldValidator2" runat="server"
ErrorMessage="Please Select an Incident" ControlToValidate="lstIncidents"
ValidationGroup="final" CssClass="style3" InitialValue="None" Display="Dynamic">
</asp:RequiredFieldValidator>
I wrote a simple asp.net code with the asp.net required validator control, the problem is that I only have one submit button called GO, and a dropdownlist that looks for the selection :
clear, submit, cancel.
No matter what option is selected, the required field validation is being fired.
Is there a way to code the page so only when the selected value is Submit it validates?
<asp:TextBox runat="server" id="txtName" />
<asp:RequiredFieldValidator runat="server" id="reqName" controltovalidate="txtName" errormessage="Please enter your name!" />
<br /><br />
<asp:DropDownList ID="dpAction" runat="server">
<asp:ListItem>Submit</asp:ListItem>
<asp:ListItem Value="Reset">Reset</asp:ListItem>
<asp:ListItem>Cancel</asp:ListItem>
</asp:DropDownList>
<asp:Button ID="btnAction" runat="server" onclick="btnAction_Click" Text="Go"
Width="40px" />
You will probably have to use a custom validator, and you would need to write the client side code for it also if you want client side validation.
I'm assuming you have a text box or something else that is required when "dpAction" is set to "Submit"?
So for example you would do something like this in your markup
<asp:CustomValidator id="CustomValidator1" runat="server"
OnServerValidate="TextValidate"
ControlToValidate="TextBox1"
ErrorMessage="Text must be specified if Submit is selected">
and in your code-behind
protected void TextValidate(object source, ServerValidateEventArgs args)
{
args.IsValid = dpAction.SelectedValue == "Submit" && !String.IsNullOrEmpty(textbox1.Text);
}
using "required" attribute.
its new in html 5
you should set ValidationGroup for each Validator!
for all controls that you want to be validated and the button to fire the validation:
and the button must have same validaton group with your validator!
If have the below markup.
<asp:checkbox id="chkTVLic" runat="server" text="TV Licence" oncheckedchanged="chkDocs_CheckChanged"
autopostback="true" CausesValidation="false" />
<asp:panel id="pnlTVLic" runat="server" visible="false">

The app is written in c# but i havn't posted any actual code as all the user code related to this markup seems to work fine.
The problem is the CheckBox chkTVLic has causes validation set to false and autopostback set to true. So whatever happens when i check and uncheck the checkbox it should postback. Most of the time this is exactly what it does and the result is to show and hide pnlTVLic when it is checked and unchecked. However if any on the validators within the panel fire, the checkbox does not cause a postback the first time. It will on all subsequent times but never the first. However it should ALWAYS cause a postback. What could be stopping it. Before someone asks there is no use written client side code, everything is pure .net markup and c# code.
I don't see why it shouldn't postback when you check/uncheck the checkbox, but if the only purpose of that checkbox is to hide/unhide a panel, I would rather do it in javascript. Doing a full postback to the server just for hiding some panel seems really bad.
In javascript you can do this to hide the panel:
document.getElementById('<%=pnlTVLic.ClientID%>').display='none';
And this to show it:
document.getElementById('<%=pnlTVLic.ClientID%>').display='block';
It's going to be so much faster and better. Just put a regular checkbox instead of the ASP.NET one and subscribe to the onclick event.
Sorry, one more comment:
I think you are wrong when you say that the checkbox should ALWAYS cause a postback. No, if one of the validators fires inside the panel, the checkbox will not cause a postback until the condition is satisfied.
This is what I did and it worked.
on checkbox onclick event I disabled all the validation controls and immediately did Page_ClientValidate(); and it worked.
I have used a required field validator followed by a regular expression validator but the required field validator is not working.....
<asp:TextBox ID="txtSummary" runat="server" TextMode="MultiLine" Width="700px"
CssClass="txtStyle" Font-Names="Arial" MaxLength="1000"
ValidationGroup="Valtxt" TabIndex="2" Rows="4">
</asp:TextBox>
<asp:RegularExpressionValidator ID="regValSummary" runat="server"
ControlToValidate="txtSummary" Display="Dynamic"
ValidationExpression="[^<>&#!]*" ValidationGroup="Valtxt">
Invalid characters(<>&#!) are not allowed
</asp:RegularExpressionValidator>
<asp:RequiredFieldValidator ID="reqvalSummary" runat="server"
ControlToValidate="txtSummary" ErrorMessage="Summary is required"
ValidationGroup="Valtxt" Display="Dynamic">
</asp:RequiredFieldValidator>
can anyone sees the problem???
The RequiredFieldValidator is triggered by the client side onchange event. It sounds like you're expecting it to be triggered by the onblur event, such that tabbing away from the textbox would fire the validation.
Before jumping to that, I suspect this is what you are seeing and to validate that it's actually working you need to trigger onchange. To do so, enter some text in the textbox, tab away, tab back to it, clear the textbox, then tab away once more. You should now see the RequiredFieldValidator's error message since it's contents have changed.
Back to the onblur issue. To accomplish that behavior you could add the onblur attribute in your code-behind and have it call the ValidatorValidate(...) JavaScript method as follows:
void Page_Load(object sender, EventArgs e)
{
txtSummary.Attributes.Add("onblur", "ValidatorValidate(" + reqvalSummary.ClientID + ")");
}
Alternately, you could accomplish the same thing in markup. First, add this script block:
<script type="text/javascript">
function rfvBlur() {
var rfv = document.getElementById("<%= reqvalSummary.ClientID %>");
ValidatorValidate(rfv);
}
</script>
Second, update the <asp:TextBox.../> markup by adding onblur="rfvBlur()" so that it now looks like this:
<asp:TextBox ID="txtSummary" runat="server" TextMode="MultiLine" Width="700px" CausesValidation="true"
CssClass="txtStyle" Font-Names="Arial" MaxLength="1000" ValidationGroup="Valtxt"
TabIndex="2" Rows="4" onblur="rfvBlur()" />
Yet another option is to validate the entire ValidationGroup by adding the following attribute to your <asp:TextBox.../> markup (no additional script block needed):
onblur="Page_ClientValidate('Valtxt')"
Adding this line to <appSettings> section of web.config worked for me (I had a problem when all validators stopped working when project was upgraded to .NET 4.5):
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />

Why don't you change the regular expression of the "RegEx" validator to check if the textbox is empty instead of use another validator?
Anyway probabily you have not specify ValidationGroup="Valtxt" for the button or the control that raise the postback. Just add ValidationGroup="Valtxt" to the button or the server control that raise the post to the page
I put the following at the top of my btn_Click event handler (to prevent further code execution) and upon 'return', the rfv messages show...
Page.Validate("your validation group");
if (!Page.IsValid)
{
return;
}
<asp:TextBox ID="txtSummary" runat="server" TextMode="MultiLine" Width="700px"
CssClass="txtStyle" Font-Names="Arial" MaxLength="1000"
TabIndex="2" Rows="4">
</asp:TextBox>
<asp:RegularExpressionValidator ID="regValSummary" runat="server"
ControlToValidate="txtSummary" ErrorMessage="Invalid characters(<>&#!) are not allowed" Text="*"
ValidationExpression="[^<>&#!]*" ValidationGroup="Valtxt">
