Validation summary is not working - asp.net

I didn't get the "'*' - Required Field Can't Be Left Blank" as my output when I execute the form, eventhough I left the required textbox blank , please try to help me...
This is my validation summary code:
<asp:ValidationSummary ID="ValidationSummary1"
ForeColor="Red" HeaderText="'*' - Required Field Can't Be Left Blank"
EnableClientScript="true" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="TextBox2" ErrorMessage="*" Display="Dynamic" ForeColor="Red" ValidationGroup="login"></asp:RequiredFieldValidator>

You need to have RequiredFieldValidator control to your textbox and then only ValidationSummary will show the result
If you using ValidationGroup for RequiredFieldValidator then you must give the same in ValidationSummary and the button as well

Please try this below code in your page's head section.
and please note that #ValidationSummary1 is Id of validation summary control. If you have provided other Id than this. place do change accordingly.
this will display error summary without bullet-list.
<style type="text/css">
#ValidationSummary1 ul li
{
list-style-type: none;
}
</style>

RegularExpressionValidator and ValidationSummary text displayed but not summary

Can I use clientscript in validation controls while also having my own onblur event? The trouble Im having is getting the validationsummary to be displayed, but the text shows beside each textbox, just not the summary.
Validation controls:
<asp:TextBox runat="server" ID="txtTimeFrameFrom" style="width:50px;font-size:x-small;" onblur="javascript:updatePackageTime1(this);" Text='<%# DataBinder.Eval(Container.DataItem, "TimeFrameFrom")%>'></asp:TextBox>
<asp:RegularExpressionValidator ValidationGroup="grpValidTimeFrame" EnableClientScript="true" Display="Dynamic" Text="<font color='red'>*</font>" ErrorMessage='check format in time from' ControlToValidate="txtTimeFrameFrom" ID="ValidTimeFrameFrom" ValidationExpression="^(1[0-2]|0[1-9]):[0-5][0-9]\040(AM|am|PM|pm)$" runat="server"></asp:RegularExpressionValidator>
<asp:TextBox runat="server" ID="txtTimeFrameTo" style="width:50px;font-size:x-small;" onblur="javascript:updatePackageTime2(this);" Text='<%# DataBinder.Eval(Container.DataItem, "TimeFrameTo")%>'></asp:TextBox>
<asp:RegularExpressionValidator ValidationGroup="grpValidTimeFrame" EnableClientScript="true" Display="Dynamic" Text="<font color='red'>*</font>" ErrorMessage='check format in time to' ControlToValidate="txtTimeFrameTo" ID="ValidTimeFrameTo" ValidationExpression="^(1[0-2]|0[1-9]):[0-5][0-9]\040(AM|am|PM|pm)$" runat="server"></asp:RegularExpressionValidator>
ValidationSummary:
<asp:ValidationSummary ValidationGroup="grpValidTimeFrame" id="ValidationSummary1" runat="server" HeaderText="You received the following errors:"> </asp:ValidationSummary>
When I enter a value in one of the textboxes that cause a validation error, I see a message in the bottom of the browser window (chrome) that seems to indicate a javascript problem (javascript:void(0))
If you set the display to None then it shows the ErrorMessage only in the ValdiationSummary.
Display="None"
And why this? Text="<font color='red'>*</font>". Better keep thing neat and clean and give your validators their own class
CssClass="myValidator"
<style>
.myValidator { color: red; }
</style>

ASP.net Custom Validator message not displaying

I have a div which acts like a modal popup. Inside that, I need a validation for which I setup a custom validator. But the message doesn't get fired, though the alert box does.
My code:
if ((oldFromTime <= newFromTime) && (oldToTime > newFromTime)) {
alert("Choose time ahead of the ones saved earlier.!");
arguments.IsValid = false;
}
else {
arguments.IsValid = true;
}
And my custom validator
<asp:CustomValidator id="cboToTimeMins_CustomValidator" ControlToValidate="cboToTimeMins" ClientValidationFunction="validateTime"
Display="static" ErrorMessage="Selected time range falls in the range of the ones saved earlier...! Choose another." runat="server" ValidationGroup="Timetable"/>
cboToTimeMins is my dropdown box, and I need to set the validation message based on the value selected from it.
Is there something wrong in my code?
P.S. I am in need of only CLIENT SIDE validation.
Here's my solution. I removed the custom validator for the Dropdown and added it to a button instead. Also, I removed the alert message in the Javascript function.
Here's my example solution
<td class="normal">Price<span class="required">*</span></td>
<td class="normal" colspan="6">
<asp:TextBox ID="txtPrice" CssClass="text" Enabled="true" runat="server" MaxLength="10" Width="100px" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="txtPrice"
ErrorMessage="* Please Input Your Price" Display="Dynamic" ValidationGroup="hdrValidation"/>
</td>
And you need to validate
Page.Validate("hdrValidation")
If Not Page.IsValid Then Exit Sub

ASP.NET Required Field Validator not working

Hi all I need a required field validator for my textbox..This is my textbox..
<asp:TextBox ID="txtTimeSlotGroupName" runat="server" AutoPostBack="false"
ClientIDMode="Static"></asp:TextBox>
<font color="red">*</font>
<asp:RequiredFieldValidator ID="RequiredFieldValidator_txtTimeSlotGroupName"
runat="server" ControlToValidate="txtTimeSlotGroupName" Display="None"
ErrorMessage="Timeslot Group Required!" ForeColor="Red" InitialValue="0"
ValidationGroup="TimeSlot"></asp:RequiredFieldValidator>
My button:
<asp:Button ID="btnAddTimeSlots" Text="Add Timeslots" CssClass="button"
runat="server" OnClick="btnAddTimeslots_Click" ValidationGroup="TimeSlot"
OnClientClick="javascript:shouldsubmit=true;"/>
I am not getting the error message. Any solutions?
You have to define the Validation Group Of your Textbox too....to make it work
<asp:TextBox ID="txtTimeSlotGroupName" runat="server"
AutoPostBack="false" ValidationGroup="TimeSlot" ClientIDMode="Static"></asp:TextBox>
Remove InitialValue="0" from the RequiredFieldValidator tag, it is not required when you are validating the textbox.
Even I was facing the same issue. Kindly check if any javascript are present on your page. Irrespective of above make use of Page.Validate() method and if(Page.IsValid) in your code. This will automatically force your validation controls and issue will be solved
If two objects have the same id the required field validator Does not work.
You just add ValidationGroup="TimeSlot" in textbox
<asp:TextBox ID="txtTimeSlotGroupName" runat="server" AutoPostBack="false"
ValidationGroup="TimeSlot" ClientIDMode="Static"></asp:TextBox>
I had this same issue... but none of the above answers were the fix for me...
My problem was that I was missing the Page.isValid in my button press method. Below is my button code and the method called by the button.
Button:
<asp:Button ID="btnBtmSave" runat="server" Text="Save" OnClick="btnSave_Click" BtnGroup="save" TabIndex="18" />
Button method:
protected void btnSave_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
//Logic goes here
}
}
make the same Validation Group Of all your text and Add button and Validation
ValidationGroup="AAA"
and add the code to your save button:
If (Page.IsValid) Then
YOURSQL.Insert()
'or ur code here'
End If
In my case, For button, I was using both client side validation i.e onClientClick="return validate()", and ASP.NET Validation i.e Reguired field Validation (ValidationGroup). Hence the Required field validators were not firing.

Validation summary display separately for each text box. in a asp.net website

<asp:TextBox ID="txt_Subject" runat="server" CssClass="txt_box"></asp:TextBox>
<asp:RequiredFieldValidator ID="valSubjectRequired" ControlToValidate="txt_Subject"
ErrorMessage="Subject is a required field." EnableClientScript="true" Display="None"
runat="server" />
<asp:ValidationSummary ID="ValSummary" HeaderText="" ShowSummary="True" DisplayMode="List"
runat="server" Style="z-index: 1; left: 437px; top: 118px; color: Maroon; />
I have this text box and validation controls. I have many text box and every text box is a required field I display the error message in the validation summary. I have positioned the validation summary below the form. I have text box and labels inside the table tag. How can I display the error message next to the text box. I have to scroll down and Up to find out what are the req fields. Instead I want to display next to the text box.
If you don't want to show the validation summary then you can delete it or set the "ShowSummary" to false. Personally I do this and then set the "ShowMessageBox" to true so the user gets an alert.
The text that displays in the alert is whatever you put in the "ErrorMessage" of the "RequiredFieldValidator". The "RequiredFieldValidator" also has a property called "Text". This becomes your error message next to the text box.
<asp:TextBox ID="txt_Subject" runat="server" CssClass="txt_box" />
<asp:RequiredFieldValidator ID="valSubjectRequired" runat="server" ControlToValidate="txt_Subject" ErrorMessage="Error message shown in pop-up" Text="Error Message shown next to the text box" />
<asp:ValidationSummary ID="ValSummary" runat="server" HeaderText="" ShowSummary="false" ShowMessageBox="true" />
If I understood correctly, you want to display the validation error messages next to the textboxes and don't need to display them at the bottom. If this is so, remove the ValidationSummary control from the page. This results in displaying the error message where the Validator controls are placed.
Hope this helps!!

Required field validator not working

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">
</asp:RegularExpressionValidator>
<asp:RequiredFieldValidator ID="reqvalSummary" runat="server"
ControlToValidate="txtSummary" ErrorMessage="Summary is required" Text="*"
ValidationGroup="Valtxt">
</asp:RequiredFieldValidator>
