i am using validation control of asp.net . i got 10 fields and i have field validators with each of them . Now I want to show error but using ValidationSummary but errors also appear with individual validators. cant i close the individual error messages?
have you add a validation group.
try like this
<asp:ValidationSummary ID="ValidationSummaryVerifyInfo"
ValidationGroup="Verify" runat="server" DisplayMode="List"
ShowMessageBox="True" ShowSummary="False" />
<asp:RequiredFieldValidator ID="RFVEmail" runat="server"
ErrorMessage="Please enter Email Id." ForeColor="Red" SetFocusOnError="True"
ValidationGroup="Verify" ControlToValidate="TextBoxEmail">*</asp:RequiredFieldValidator>
To hide the validators you can place them into one div with CSS style display: none.

I have more than one RequiredFieldvalidator in my markup, I want to check that all fields are entered, and if not I want to show an alert saying so.
Try ValidationSummary control
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
http://asp-net-example.blogspot.nl/2008/10/validationsummary-example-how-to-use.html
I am having trouble with the <asp:RequiredFieldValidator> in this code.
<asp:Label ID="email_Label" runat="server" Text="Email"></asp:Label>
<asp:TextBox ID="email_Text" runat="server" MaxLength="40" Width="250"></asp:TextBox> *
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server" ControlToValidate="email_Text" Text="Required"></asp:RequiredFieldValidator>
According to the W3schools documentation here I have used the <asp:RequiredFieldValidator> correctly, however instead of displaying the label and text box the page also displays the error message. This happens on page_load so the value has not had a chance to change from the default yet. I want the error text to display after the user clicks the Save button at the bottom of the form I am building.
What is Being Displayed:
Email[TextBox] * Required
What Should Be displayed:
Email[TextBox] *
Am I missing a parent element for the validator or something. According to the example on w3schools site no parent element should be needed. In fact the way they have their example set-up is exactly what I was expecting for this.
Use Validation Group if want to display Error message on Button click. Like this.
<asp:RequiredFieldValidator ID="rqtxtQName" ValidationGroup="save" ControlToValidate="txtQueueName" runat="server" ErrorMessage="Some required field are missing." SetFocusOnError="True"Display="Dynamic"></asp:RequiredFieldValidator>
and use validation group on Button also.
<asp:Button ID="btnSubmit" runat="server" Text="Submit" ValidationGroup="save" OnClick="btnSubmit_Click"/>
Hope it will helps.
you should use ErrorMessage instead of Text
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server" ControlToValidate="email_Text" ErrorMessage="Required"></asp:RequiredFieldValidator>
If you want to validation on save button click event then set property ValidationGroup="Group1"
for RequiredFieldValidator and also for save button. So it will check validation when you click save button.
And For display message you can use ErrorMessage property.

Set the RequiredFieldValidator this way. Remove the property: 'TextRequired' & put a * inbetween the opening and closing tag.
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server"
ControlToValidate="email_Text">*</asp:RequiredFieldValidator>
Also, Do not set the ErrorMessage property as this will again not fit your requirements.
I have the following textbox alongwith its validators, but when I enter the correct text it fires up the RegularExpressionValidator error message, can't really figure out what I am doing wrong
<asp:TextBox ID="txtName" runat="server" onkeypress="return keyRestrict(event,'abcdefghijklmnopqrstuvwxyz-0123456789')"
AutoCompleteType="Disabled" Width="199px"></asp:TextBox><span style="color: Red">*</span>
<asp:RequiredFieldValidator Display="Dynamic" ID="RequiredFieldValidator3" runat="server"
ControlToValidate="txtName"></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="revName" runat="server" ControlToValidate="txtName"
CssClass="text-error" Display="Dynamic" ValidationExpression="^[\p{L}\s]+$" ErrorMessage="Invalid Name"></asp:RegularExpressionValidator>
I also used the ValidationExpression ^[A-Za-z]+$ in order to test that whether there exist some error in the ValidationExpression, and then typed in Name in the textbox being validated and still it triggered the error message of the RegularExpressionValidator.
Regards
^[\p{L}\s]+$ would match 1 or more letters only(not digits) or space..
If you want to validate it with digits you have to use
^[\p{L}\p{N}\s]+$
This would match unicode letters,numbers and space 1 to many times
I think this problem is probably a simple solution.
Im trying to use Validation Summary control, when i run the page and enter invalid input i get the error summmary (fine) but when i try to rectify the error by entering correct info the page wont run and the summary stays (even though the Validation Control message goes.)
Thanks
<asp:RegularExpressionValidator ID="regexStns" runat="server"
ControlToValidate="txtStones"
ErrorMessage="Weight (Stns) Must be one or two number characters."
ValidationExpression="/d/d?"></asp:RegularExpressionValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
ControlToValidate="txtPounds" ErrorMessage="RegularExpressionValidator"
ValidationExpression="\d\d?"></asp:RegularExpressionValidator>
<br />
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
<br />
That is the normal behavior of the ValidationSummary control.
I have an ASP.NET page developed in VS 2008. there is a text box and login button.Required fireld validator and Validtion Group controls are associate for validation.I wrote code for the Button click evenet handler too.But the Button click is not getting fired.There is no post back happening. Can any one tell me why ?
HTM lmarkup
<asp:TextBox ID="txtLoginPass" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" ControlToValidate="txtPassword" ValidationGroup="Login" ErrorMessage="Please enter password." runat="server" />
<asp:Button ID="btnLogin" runat="server" Text="Login"
onclick="btnLogin_Click" ValidationGroup="Login" />
Validators generate client side JavaScript which can prevent a postback if the required field is empty.
Is that exact code snippet? It didn't work at all - no such control as txtPassword.
Altough, this worked as expected:
<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" ControlToValidate="txtPassword" ValidationGroup="Login" ErrorMessage="Please enter password." runat="server" />
<asp:Button ID="btnLogin" runat="server" Text="Login"
onclick="btnLogin_Click" ValidationGroup="Login" />
I'm sure that you've got that correct in your code, so the problem must be somewhere else - could please post more code surrounding this snippet?
I expect that you have AutoPostBack="True" on one of your components. If so then remove that and your onclick should work on the button.
I had this same exact problem. The RequiredFieldValidator was working as expected when the textbox was empty, but the button click wasn't causing a postback when there was text. My problem? I was using the same validationgroup name in a separate user control. So make sure all of your validationgroup names are unique.
