Validation summary not showing in master page

Hi, I am using User controls in my web page. I have validation controls in my user control and the validation summary control is placed in the master page. Problem is I am not getting the errors displayed when I am running my application. Any help is appreciated.   Thanks.

Adding New Error Message to Validation Summary Control



 In the code behind based on a condition i want to add a error message to the Validation Control.

 I tried the below.

 'Call function to add error message.
protected void AddErrorToValidationSummary(string errorMessage)
 CustomValidator custVal = new CustomValidator();   
 custVal.IsValid = false;   
 custVal.ErrorMessage = errorMessage;  
 custVal.EnableClientScript = false;   
 custVal.Display = ValidatorDisplay.None;        



Validation Summary with regular Expression validator


I have a page that im using Validation Summary on. I have 5 out of 8 fields that im validating. All 5 have required validators and 1 of the 5 also has regularexpressionvalidator with it.

When the page load and i click the submit, all the fields show my red * next to them and the individual messages down in the summary. Thats find, but im having issues with checking the field with the regex validation when you submit the form again. At the moment, i had added a if condition on the button event and it is preventing the form from submitting and the field is showing the red * next to it, but my message from the regex validator does not display in the summary. Actually the summary doesnt even show up. The regex validator works when you tab out of the field by placing the red *, but the actual error message doesnt display in the summary, so you wouldnt know why there is an issue.


I have the following as a test, def isnt correct, but was trying to show the summary with the value from my regex validator:

        protected void btnInfo_Click(object sender, EventArgs e)
            if (!Page.IsValid)
                vsSumm.ShowSummary = true;

1 page, 2 validationgroups and 2 validation summary issues


Hi all,

I have one page, on which I have a part with controls and one validationgroup, with the respective validation summary.

I have another part on the same page with another validation group, and another validation summary.

The thing is that, when I press btnGo or btnGo2, both validationsummaries trigger, and both show all validation messages. For other words, it seems that the validationgroups are not working.

My html:

<!--Group 1-->
<tr style="padding-top:3px;">
    <td class="mgmCell">
    <td style="padding-left:5px;">
        <asp:TextBox ID="txtName" runat="server" ValidationGroup="Group1"/>
        <asp:RequiredFieldValidator ID="rfvName" runat="server" ErrorMessage="Name" Text="*" ValidationGroup="Group1" ControlToValidate="txtName" />
    <td colspan="2">
        <asp:Button ID="btnGo" runat="server" Text="Go" ValidationGroup="Group1" OnClick="ClickEvent" />
        <asp:ValidationSummary ID="vs1" runat="server" ShowSummary="fal

how to set up different validation summary for different type of validators


Hi guys,

what i want to do is to  set up different validation summary for different type of validators. for example, for required field validators, if user leaves some required field blank, it shows that "You have to fill in mandantory information, indicated with a star"

and if some format is wrong, it shows that "format is invalid"

right now, i set all requied field validators' text to be a star, and leave error message to be blank. so that the validation summart will only display the header message. that is what i need. what i dont know is how to separate regular expression into another summary.

i think the validation group property requires multiple buttons. however, i only want one submit button, and this is where i got stuck.


any help is appreciated! Thanks in advance.

VS 2010 HTML validation "in CSS" option - where the hell is it?


In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.

1. am I blind?

2. they decided it is too convenient to use and removed it?

3. they will "introduce" it in SP1?

What is going on? That one thing made me move back to VS 2008 web developer.

But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.


set messageTemplateResourceName from resource file in Validation appication block.



  I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.

Here is my code:

<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250"
              upperBoundType="Inclusive" negated="false" messageTemplate=""
              messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=, Culture=neutral, PublicKeyToken=null"
              tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris
