I used asp required field in my code but data in text box are sending even they are empty when clicking on the button and after they are sending, message of required field appears!!
Please help! Thanks in advance...
The source code looks like this
<asp:Label ID="LabelUserName" runat="server" AssociatedControlID="UserName" meta:resourcekey="UserName">Nom :</asp:Label>
<asp:TextBox ID="UserName" runat="server" ValidationGroup="val" ></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Entrez your name " ControlToValidate="UserName" ForeColor="Red" ValidationGroup="val">
</asp:RequiredFieldValidator>
Here is the code of the button :
<asp:Button runat="server" Text="Envoyer" ID="Button1" Width="78px" ValidationGroup="val" />
Can't say for sure without seeing the code inside the event handle for your button click, but my guess is you are missing a check to be sure the page is valid. For example:
If (Page.IsValid) Then
' do your thing
Else
'do nothing
End If
I think the required will help you to solve this issue of field validator
eg:
<asp:TextBox ID="UserName" runat="server" required="required"></asp:TextBox>

I have 2 textboxes called minimum version and maximum version requesting user to enter Version ( like 1.3.4 ). At a given time only one can be blank, not both So I have provided custom field validator .Also I have provided regular expression to validate if values entered are proper.
When I click on button entering invalid version field I can see button click event is getting triggered. Could you please help.
<asp:Label ID="lblMinimum" runat="server" Text="Minimum Version : " CssClass="alignLeft"></asp:Label>
<asp:TextBox ID="txtMinimumVersion" runat="server" Width="312px" CssClass="alignRight" ValidationGroup="validate"></asp:TextBox>
<asp:RegularExpressionValidator ID="revModuleVersion" runat="server" ControlToValidate="txtMinimumVersion"
ValidationExpression="^\d+(\.\d+)+$" ErrorMessage="* Please enter valid version number" ValidationGroup="validate"/>
<asp:Label ID="lblMaximum" runat="server" Text="Maximum Version : " CssClass="alignLeft"></asp:Label>
<asp:TextBox ID="txtMaximumVersion" runat="server" Width="312px" CssClass="alignRight" ValidationGroup="validate"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtMaximumVersion"
ValidationExpression="^\d+(\.\d+)+$" ErrorMessage="* Please enter valid version number" ValidationGroup="validate"/>
<asp:Button ID="btnUpdateNow" runat="server" EnableViewState="False" Text="Create now"
OnClick="btnCreateNow_Click" CausesValidation="false" ValidationGroup="validate"></asp:Button>
<asp:CustomValidator ID="custValidateModuleVersion" runat="server" Display="Dynamic" ErrorMessage="* Maximum version should be greather or equal to Minimum version"
OnServerValidate="custValidateModuleVersion_ServerValidate"></asp:CustomValidator>
<asp:CustomValidator ID="custValidate" runat="server" Display="Dynamic" ErrorMessage="* Please enter atleast one version"
OnServerValidate="CustomValidator_ServerValidate"></asp:CustomValidator>
You have mentioned CausesValidation = "false". Make it as true or remove it
<asp:Button ID="btnUpdateNow" runat="server" EnableViewState="False" Text="Create now" OnClick="btnCreateNow_Click" ValidationGroup="validate"></asp:Button>
The CausesValidation property specifies if a page is validated when a Button control is clicked.
Page validation is performed when a button is clicked by default.
This property is mostly used to prevent validation when a cancel or reset button is clicked.
inside the list view i put a email validation and validation summary, when i press edit it will not validation on client side. how to make it able to validate on client side
<span class="title1">Email Address<span style="margin-left:28px;">:</span></span><span style=" margin-left:100px;">
<asp:TextBox ID="SecurityAnsLabel" runat="server" Text='<%# Bind("EmailAdd") %>' Height="25px" Width="200px"/>
<asp:RegularExpressionValidator ID="regexEmailValid" runat="server" ValidationExpression="\w+([-+.]\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*" ControlToValidate="SecurityAnsLabel" ErrorMessage="Invalid Email Format" ForeColor="Red" Text="*" SetFocusOnError="True"></asp:RegularExpressionValidator></span>
Set the ValidationGroup property of all the controls(textbox, regular expression control,the button if there is any) involved in this as same like 'EmailValidate'
Hope this works :)
I've got a weird problem that i don't understand why it happened.
I made a content page so a user can send me a message to my email and made a few TextBox's that are linked to some validators.
when i first made the page i hed 1 Regular Expression validator and every thing worked out fine like i planed it, But then i decided to delete the Regular Expression validator and now i got a problem with the Required Field validator.
when i press submit the page do a post back like there isn't any validators on the page.
I'm pretty sure I'm missing something (I'm pretty new at asp.net)
here is the markup:
<!-- Regular Expression Validtor for the Name Text Box
<asp:RegularExpressionValidator ID="NameExpressionValidator1" runat="server" ControlToValidate="nameTextBox"
ValidationExpression="[אבגדהוזחטיכלמנסעפצקרשתץףןם\s\.]*" Display="Dynamic"> </asp:RegularExpressionValidator> -->
<!--The Name Text Box -->
<asp:TextBox ID="nameTextBox" class="TextBoxes" runat="server"
AutoPostBack="True" ValidationGroup="g" ></asp:TextBox> <span class="infoText">:שם</span>
<!-- Required Field Validator for the Name Text Box -->
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="nameTextBox"
Display="Dynamic" ValidationGroup="g" ErrorMessage="please enter your name"></asp:RequiredFieldValidator>
<br />
<br />
<!-- Phone Text Box -->
<asp:TextBox ID="phoneTestBox" class="TextBoxes" runat="server"
AutoPostBack="True" ValidationGroup="g" ></asp:TextBox> <span class="infoText">:טלפון</span>
<!-- Requierd Field Validator Phone Text Box -->
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="phoneTestBox"
Display="Dynamic" ValidationGroup="g" ErrorMessage="please enter your phone"></asp:RequiredFieldValidator>
<br />
<br />
<asp:TextBox ID="messagTextBox" runat="server" class="TextBoxes" TextMode="MultiLine"
Text="asdasdadasdasdasd"></asp:TextBox> <span class="infoText">:הודעה</span>
<asp:Button ID="button" runat="server" Text="send message" ValidationGroup="g" />
You should not use HTML comments to comment out server side controls but <%-- --%>:
<%--
<asp:RegularExpressionValidator ID="NameExpressionValidator1" runat="server" ControlToValidate="nameTextBox"
ValidationExpression="[אבגדהוזחטיכלמנסעפצקרשתץףןם\s\.]*" Display="Dynamic"> </asp:RegularExpressionValidator>
--%>

Is there any specific use of AutoPostBack="True" in textbox? if not then just remove it from all textboxes, also you need to give ValidationGroup="g" for only validator controls, there is no need to give it in textbox controls.
first of all, ensure the validation group of the validation summary matches?
If that's correct try using validation method:
protected void Page_Load(object sender, EventArgs e)
{
Validate();
}
Has anyone ever seen this and does anyone know how to fix it ...
The validation Summary control seems to be rendering this :
error message
<br>
error message
<div style="display: none;" id="summaryID">
</div>
Correct me if i'm wrong here but shouldn't my errors be inside that div ... hense the reason you can put a cssclass on the control server side using CssClass="whatever" ?
Or did i miss something?
EDIT :
Just to verify ... this is what i expect it to render :
<div style="display: none;" id="summaryID">
error message
<br>
error message
</div>
EDIT 2 :
Server side markup that produces this is ...
<asp:ValidationSummary ID="ui_ValidationSummary" runat="server" />
...
Loads of controls but here's an example (don'twant to over complicate things) :
...
<asp:TextBox ID="ui_txtClientDOB" runat="server" />
<asp:RangeValidator ID="ui_RangeValidator_DOB" runat="server" ControlToValidate="ui_txtClientDOB" ErrorMessage="DOB is not valid" MinimumValue="1900/01/01" Type="Date" ForeColor="Red">*</asp:RangeValidator>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="ui_txtClientDOB" ErrorMessage="DOB is missing" ForeColor="Red">*</asp:RequiredFieldValidator>
If either validator on this textbox has reason to fail the validation the result is as discussed, an empty div tag with an error next to it.
Likely the div #summaryID is where client side validation errors are show. Use a tool like firebug to see this as you can't do a view source on javascript filled markup. Otherwise, turn off client side validation and do a postback.
Edit
My guess is that you are mixing up the error message that's displayed with the validation control itself instead of inside the validation summary. If you don't supply a text property to the validation controls it will use the error message. Try the following (take away the text property and you'll see what I mean):
<asp:ValidationSummary ID="val" runat="server" CssClass="test"
DisplayMode="List" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator" Text="*"></asp:RequiredFieldValidator>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ControlToValidate="TextBox2" ErrorMessage="RequiredFieldValidator" Text="*"></asp:RequiredFieldValidator>
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:TextBox ID="Textboxtotalamount" OnTextChanged="AmountChanged"
Width="90px" AutoPostBack="true" runat="server">
</asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator" runat="server"
ControlToValidate="Textboxtotalamount"
SetFocusOnError="True" ValidationGroup="val">*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
ControlToValidate="Textboxtotalamount"
ValidationExpression="^[-+]?[1-9]\d{0,13}(\.\d{1,3})?%?$"
SetFocusOnError="True">F</asp:RegularExpressionValidator>
in this above code can validate correctly.......but in text box i call "OnTextChanged"
event ....suppose if i type(characters)in textbox errormesge shown at the same time ontextchanged event also called hen error occured ....i ve to stop OnTextChanged event when regularexpression raised......
pls help
I updated your code. see if this helps you.
<asp:TextBox ID="Textboxtotalamount" OnTextChanged="AmountChanged" ValidationGroup="val"
Width="90px" AutoPostBack="true" runat="server" CausesValidation="true">
</asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator" runat="server" ValidationGroup="val"
ControlToValidate="Textboxtotalamount"
SetFocusOnError="True" >*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
ControlToValidate="Textboxtotalamount" ValidationGroup="val"
ValidationExpression="^[-+]?[1-9]\d{0,13}(\.\d{1,3})?%?$"
SetFocusOnError="True">F</asp:RegularExpressionValidator>
I'm not sure I understood your question correctly: You want to execute the `AmountChanged´ code only if the validator did not report any errors, right? In that case, you should call
if (!this.IsValid)
return;
at the start of AmountChanged. (You might need to call this.Validate(); first, if OnTextChanged does not initiate validation by itself.)
Details can be found here: http://msdn.microsoft.com/en-us/library/dh9ad08f(VS.100).aspx
Clarification: At the moment, your code looks like this:
void AmountChanged(...) {
...
}
You need to change it to this:
void AmountChanged(...) {
if (!this.IsValid)
return;
...
}
so that the code is not executed when some validator detects an error. In addition, you must add CausesValidation="true" to your TextBox as Saar's example shows.
