ASP .NET CompareValidator control locks everything - asp.net

I have a form with a field that has a asp:CompareValidator control which checks if the text in the input is of type Integer.
The problem is that the form has some other buttons to navigate to other pages, so when the CompareValidator triggers it locks those buttons until the input in the controled field is Integer although it's not necessary to navigate.
Here's the code:
<asp:TextBox runat="server" ID="txtRelacion" placeholder="Id del evento"></asp:TextBox>
<asp:CompareValidator ID="CompareValidator1" runat="server" Operator="DataTypeCheck" Type="Integer" ControlToValidate="txtRelacion" CssClass="compare-validation-error" />
<asp:Button runat="server" ID="submitButton" Text="Submit Form"/>
<asp:Button runat="server" ID="navigateButton" Text="Navigate somewhere"/>
Is this the expected behaviour of the asp:CompareValidator control?

You can specify a ValidationGroup in your button and in your CompareValidator. Then the CompareValidator will be used only for the corresponding ValidationGroup:
<asp:TextBox runat="server" ID="txtRelacion" placeholder="Id del evento"></asp:TextBox>
<asp:CompareValidator ID="CompareValidator1" runat="server" Operator="DataTypeCheck" Type="Integer" ControlToValidate="txtRelacion" ValidationGroup="form" CssClass="compare-validation-error" />
<asp:Button runat="server" ID="submitButton" ValidationGroup="form" Text="Submit Form"/>
<asp:Button runat="server" ID="navigateButton" Text="Navigate somewhere"/>

Required Field Validator on FileUpload Control

I have a form in which I have two textboxes and one fileupload control, I am using required field validator on one textbox and on Fileupload control, When I am clicking the submit button, its disabling the fileupload control and not showing any validation for it.
I also have second button for Cancel, clicking on which redirects to previous page, when I am clicking this button its also disabling the fileuploadcontrol.
Below is my code
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:RequiredFieldValidator ID="rfvFileupload" ValidationGroup="validate" runat="server"
ControlToValidate="FileUpload1"></asp:RequiredFieldValidator>
<asp:TextBox ID="txtSubj" runat="server" ></asp:TextBox><asp:RequiredFieldValidator
ID="rfvSubject" ControlToValidate="txtSubj" runat="server" Display="Dynamic"
EnableClientScript="true" ErrorMessage="* required" ValidationGroup="validate" />
<asp:Button ID="btnupload" runat="server" Text="Send" ValidationGroup="validate"
OnClick="btnupload_Click">
<asp:Button ID="btncancel" runat="server" Text="Cancel" OnClick="btncancel_Click"
/>
Try using no ValidadationGroup:
<asp:FileUpload ID="fupDocument" runat="server" Width="100%" />
<asp:RequiredFieldValidator runat="server" Display="Dynamic" ErrorMessage="* Required Field" ControlToValidate="fupDocument">
</asp:RequiredFieldValidator>
I tried and work it.

asp.Net ValidationGroup validating correctly except on Enter key

I've seen a variety of questions here that are very close to this issue but none which seem to fit this specific scenario.
Description:
I have ID and Password fields with a Log On button in the Master page. These are in the "LoginValidationGroup" and they work fine.
Now, in the Default.aspx, I have an email TextBox and submit button that are in the "NotifyMeValidation" group, and they also work, BUT not if you hit the enter key rather than the submit button. The Submit button works fine - Enter key ... not so much.
The Enter key causes the validation to occur on the LoginValidationGroup, even though the TextBox is set to CausesValidation="true", and it is in the NotifyMeValidation group.
I guarantee people are going to enter an email in that box and hit Enter. I would!!! And when they do, they're going to see a callout balloon at the top telling them the User ID is required.
What's my error here? If I need to post the actual code I can do so.
Actually, let me just go ahead and do that.
From the Default.aspx:
<asp:RequiredFieldValidator
runat="server"
ValidationGroup="NotifyMeValidation"
ID="EmailRequiredValidator"
ControlToValidate="SenderEmailTextBox"
ErrorMessage="Email is Required"
Display="None" />
<ajaxToolkit:ValidatorCalloutExtender
runat="Server"
PopupPosition="Left"
ID="EmailRequiredValidatorExtender"
Width="185px"
TargetControlID="EmailRequiredValidator"
WarningIconImageUrl="/Images/warning.gif" />
<asp:Label ID="SenderEmailLabel" runat="server" ssociatedControlID="SenderEmailTextBox" EnableViewState="false" Text="Email:"></asp:Label>
<asp:TextBox ID="SenderEmailTextBox" runat="server" ValidationGroup="NotifyMeValidation" Width="350" BackColor="#cccccc" CausesValidation="true"></asp:TextBox>
<br /><br />
<asp:Button ID="SubmitButton" runat="server" ValidationGroup="NotifyMeValidation" EnableViewState="false" CssClass="submit" Text="Send" CausesValidation="true" OnClick="btnSubmit_Click" />
From the Master page:
<asp:Label CssClass="LoginHeading" ID="UserNameLabel" runat="server" AssociatedControlID="UserNameTextbox">UserName: </asp:Label>
<asp:TextBox CssClass="LoginTextBox" ID="UserNameTextbox" runat="server" ValidationGroup="LoginValidation" CausesValidation="True"></asp:TextBox>
<asp:Label CssClass="LoginHeading" ID="PasswordLabel" runat="server" AssociatedControlID="PasswordTextbox">Password: </asp:Label>
<asp:TextBox CssClass="LoginTextBox" ID="PasswordTextBox" runat="server" TextMode="Password" ValidationGroup="LoginValidation" CausesValidation="True"></asp:TextBox>
<asp:Button CssClass="LoginHeading" ID="LoginButton" runat="server" Text="Button" CommandName="Login" ValidationGroup="LoginValidation" CausesValidation="True" onclick="LoginButton_Click" />
And the Master page validators...
<asp:RequiredFieldValidator runat="server" ID="UIDRequired"
ValidationGroup="LoginValidation"

Try adding an <asp:Panel> around each set of controls and setting the DefaultButton property to the ID of the button you want to click when the users hits Enter.
Just to explain what is happening here, the aspx's default button is being fired when you press enter on the textbox. To handle this you could you could fire some jQuery code when the enter key is clicked on the textbox, this code will then perform the click on the specific button that you require. Check this

Input parameter 'controlId' cannot be an empty string when using validator inside formview

I have got a FormView where I have several fields. Those fields should be validated by asp.net validators, like this:
<asp:FormView ID="OrderDetails" runat="server" DataKeyNames="ID" DataSourceID="DS_Order" DefaultMode="Edit" AutoGenerateRows="false" ClientIDMode="Static" RenderOuterTable="false">
<EditItemTemplate>
<asp:TextBox ID="EinkaufsauftragsNr" runat="server" ClientIDMode="Static" Text='<%# Bind("EinkaufsauftragsNr") %>'/>
<asp:CompareValidator runat="server" Operator="DataTypeCheck" Type="Integer" ValidationGroup="EditValidation" Display="Dynamic"
ControlToValidate="EinkaufsauftragsNr" ErrorMessage="Nur Ganzzahlen erlaubt." CssClass="validator" />
.....
</EditItemTemplate>
</FormView>
But when I execute this, I get: "Input parameter 'controlId' cannot be an empty string."
When I remove the validator, the error-msg disappears as well.
After searching for this problem on the net, I thought the problem was that the control cannot be found inside the formview, so I put the clientidmode="static" there -> but that didn't solve my problem.
Do you have any other suggestions on how I could solve this one?
You did not assign id to CompareValidator Control, You have to assign ID to asp:CompareValidator
Change
<asp:CompareValidator runat="server" Operator="DataTypeCheck"
Type="Integer" ValidationGroup="EditValidation" Display="Dynamic"
ControlToValidate="EinkaufsauftragsNr" ErrorMessage="Nur Ganzzahlen erlaubt."
CssClass="validator" />
To
<asp:CompareValidator ID="SomeID" runat="server" Operator="DataTypeCheck"
Type="Integer" ValidationGroup="EditValidation" Display="Dynamic"
ControlToValidate="EinkaufsauftragsNr" ErrorMessage="Nur Ganzzahlen erlaubt."
CssClass="validator" />

asp.net: Postback disabled after validation failed

After validation failed, I have a problem with controls (dropdownlist or button) that should cause a new postback. I will try to explain it clearly...
The purpose of my page is to save fives dates in a database. The page has the following controls:
Five textboxes, each one containing a date
A reset button (CausesValidation=false) to restore a default date in one of the 5 textboxes
A dropdown list (AutoPostback=true, CausesValidation=false) of predefined templates that applies 5 dates to the 5 textboxes
A button to save the dates to the database
The textboxes can be edited manually. So, when I click the Save button, if the format of the dates is not valid, the validation fails and the save is aborted. The problem is just after that. If I click on the Reset button or select an item in the dropdownlist, the postback is not triggered. If I try again, then it works. Is there a way to make it work the first time after the first validation failed? I tried deactivating the validation on the client-side when changing the selection in the dropdownlist but the postback still does not occur.
Here is the relevant part of the code:
<asp:DropDownList ID="cboScheduleTemplates" runat="server" AutoPostBack="true" CausesValidation="false" />
<asp:TextBox ID="txtDateDelivery1" runat="server" />
<asp:RegularExpressionValidator ID="revDateDelivery1" runat="server" Display="Dynamic" ValidationGroup="Schedule" ControlToValidate="txtDateDelivery1" Text="*" />
<asp:TextBox ID="txtDateYearbookQuantity" runat="server" />
<asp:RegularExpressionValidator ID="revDateYearbookQuantity" runat="server" Display="Dynamic" ValidationGroup="Schedule" ControlToValidate="txtDateYearbookQuantity" Text="*" />
<asp:TextBox ID="txtDateDelivery2" runat="server" />
<asp:RegularExpressionValidator ID="revDateDelivery2" runat="server" Display="Dynamic" ValidationGroup="Schedule" ControlToValidate="txtDateDelivery2" Text="*" />
<asp:TextBox ID="txtDatePersonalizations" runat="server" />
<asp:RegularExpressionValidator ID="revDatePersonalizations" runat="server" Display="Dynamic" ValidationGroup="Schedule" ControlToValidate="txtDatePersonalizations" Text="*" />
<asp:TextBox ID="txtDateDelivery3" runat="server" />
<asp:Button ID="btnSetDefaultDelivery3" runat="server" ValidationGroup="Schedule" CausesValidation="false" />
<asp:RegularExpressionValidator ID="revDateDelivery3" runat="server" Display="Dynamic" ValidationGroup="Schedule" ControlToValidate="txtDateDelivery3" Text="*" />
<asp:Button ID="btnSaveSchedule" runat="server" CssClass="btnAction" Text="Save" ValidationGroup="Schedule" />
<asp:ValidationSummary ID="validationSummarySchedule" runat="server" ValidationGroup="Schedule" DisplayMode="List" />
As suggested in this post, the problem comes from calls to Page_ClientValidate. So I wrapped the client function like this and the problem went away:
function DoPageClientValidate(validationGroupName)
{
var result = Page_ClientValidate(validationGroupName);
Page_BlockSubmit = false;
return result;
}

ASP:TextBox or ASP:CheckBoxList, throwing Javascript errors when Requiredfield validator is there

I have created a User Control for my SharePoint, which has a simple TextBox and a CheckBoxList. For both of these controls, I have ASP:RequiredFieldValidator and ASP:RegularExpressionValidator.
When I select some item in the CheckBoxList or type some input in the TextBox, I am getting a javascript error in some unknown location. (This is not accepted by my customer.)
Now, when I debug this using FireBug, in the console I see validators[i] is null. It is actually failing in the JS code generated by these validators.
Can some one help me?
Edited:
<asp:TextBox ID="txtNumbers" runat="server" CssClass="Label4" ></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidatorGPC" runat="server"
ControlToValidate="txtNumbers" ErrorMessage="Only Numbers Accepted "
ValidationExpression="^\d+$"
SetFocusOnError="true"></asp:RegularExpressionValidator>
<asp:RequiredFieldValidator ID="RequiredNUMValue" runat="server" ControlToValidate="txtNumbers"
SetFocusOnError="true" ErrorMessage="Please enter a valid number"></asp:RequiredFieldValidator>
Also,
I added required field validators for RadioButtonList (not CheckBoxList).
<asp:RadioButtonList ID="rbtOptions" runat="server" CssClass="Label3">
<asp:ListItem Text="Option 1" />
<asp:ListItem Text="Option 2" />
</asp:RadioButtonList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="rbtOptions"
SetFocusOnError="true" ErrorMessage="Please Select a Valid Option"></asp:RequiredFieldValidator>
When I either input any text in the TextBox or select any option, there is a JavaScript error.
There is something else on your page that is conflicting with this. Taking what you posted and trying a simple page it works as it should, so I'm assuming that there's other elements / scripts that are causing this.
<div>
<asp:TextBox ID="txtNumbers" runat="server" CssClass="Label4"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidatorGPC" runat="server" ControlToValidate="txtNumbers" ErrorMessage="Only Numbers Accepted " ValidationExpression="^\d+$" SetFocusOnError="true"></asp:RegularExpressionValidator>
<asp:RequiredFieldValidator ID="RequiredNUMValue" runat="server" ControlToValidate="txtNumbers" SetFocusOnError="true" ErrorMessage="Please enter a valid number"></asp:RequiredFieldValidator>
<asp:RadioButtonList ID="rbtOptions" runat="server" CssClass="Label3">
<asp:ListItem Text="Option 1" />
<asp:ListItem Text="Option 2" />
</asp:RadioButtonList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="rbtOptions" SetFocusOnError="true" ErrorMessage="Please Select a Valid Option"></asp:RequiredFieldValidator>
<asp:Button ID="btnSubmit" runat="server" Text="submit" />
</div>
Do you have any script tags, or other elements in your markup that could be interfering with this?
Self closed tags can cause issues like this ( is a no no)
