I am using a custom validator to call a javascript function for validation. My problem is that I need to be able to change the error message dynamically. Here is the code:
<asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="fcnValid1"
ErrorMessage="" Display="None" ValidateEmptyText="True">
</asp:CustomValidator>
[code]....
I have tried in many way but the error message for custom validator is not shown in validation summary but it(ValidationSummary) shows error message for every other type of validator.
[code]....
I have a requirement that one of multiple fields is required. Using custom validator the even fires, false is returned, but no error message is display and the form validates. What am I missing? I have tried with and without ValidationSummary.
<asp:CustomValidator ID="CustomValidator1" OnServerValidate="validatePhone" EnableClientScript="false" runat="server" ErrorMessage="Home or Cell Phone is Required" ></asp:CustomValidator>
<asp:ValidationSummary ID="ValidationSummary1" DisplayMode="BulletList" runat="server" ForeColor="Red" Font-Size="X-Small" Font-Bold="true" />
protected void validatePhone(object sender, ServerValidateEventArgs e)
{
e.IsValid = string.IsNullOrEmpty(txtCellPhone.Text) && string.IsNullOrEmpty(txtHomePhone.Text) ? false : true;
}
I have a custom validator:
<asp:CustomValidator ID="QuestionValidator" runat="server" ErrorMessage="Please select an option" ClientValidationFunction="QuestionValidator_ServerValidate" OnServerValidate="QuestionValidator_ServerValidate" ValidateEmptyText="true"></asp:CustomValidator>
[code]...
When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.
i ahve one custvalidator control in that i have used OnServerValidate="ValidateDateRange"
ValidateDateRange is function i have written in serverside now i want raise error message without
postback operation like (clientside validation) if that ValidateDateRange function returns
false .
I have an aspx page with lots of controls on it. I am using a custom validator control (with the serverside validation). Is there a way to display the error message on the validation summary without writing Javasccript. I am a beginner in .NET and am not fluent in Javascript. This is the custom validator HTML
<asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="Invalid Date"
ControlToValidate="txtDate" OnServerValidate="ValidateDate_ServerValidate" ValidationGroup="vgSetUp"
></asp:CustomValidator>
This is the utility method am trying to validate for the entry on the UI, so that it takes dates only in these described formats If the user enters date in any other format, this method returns returns the Datetime.Mivalue(1/1/0001)
public DateTime GetFomattedDate(string dateString)
{
try
{
string[] formats = {
"MMddyyyy", // These are the accepted date formats for the UI
"MM/dd/yyyy",
"M/d/yyyy",
"yyyy/MM/dd",
"yyyy/M/d"
};
DateTime EffDate = DateTime.MinValue;
if ( DateTime.TryParseExact(dateString,formats, null, System.Globalization.DateTimeStyles.None, out EffDate))
{
return EffDate;
}
}
catch (Exception)
{
throw;
}
return DateTime.MinValue;
}
This is my customvalidator event handler(code behind)
protected void ValidateDate_ServerValidate(object source,servervalidate eventargs args)
{
args.IsValid = GetFomattedDate(args.Value) ==DateTime.MinValue? false:true;
}
I am able to validate it properly, but I cannot display the error message in the validation summary along with other messages. Anyone who is expert on Javascript can Help with the javascript function?
I know the built-in ASP.Net validators come with a client-side framework, however I've been unable to find anything that lets me check a single validator for it's Valid state.
The validator in question is a RegularExpressionValidator, which I use to determine whether an e-mail address is valid or not.
Here's some brief code:

How can I get ClientSide(JavaScript) Value for My ASP.net Custom Control?
for example I want to get a value like this:
var selectedItemID = getElementById("<%=MyControl1.ClientId%>").value;
How can i set a specific Value in my control scripts to get it from ".value" property like above?
Additional Note:
i want ".value" property(javascript) to get the dropDown control(one of my controls in my custom control) selected Value.
I have a razor view in ASP.NET MVC3 application.This view has 2 partialviews PartialView1 is strongly typed and binded with the model.PartialView2 is not binded with the model.and this view consists of a collection of checkboxes.As part of validation atleast one checkbox must be checked to continue with the save.
Following is the jquery code that is giving me error:
Object does not support this property or method.
Error occuring at this line of code:
$("#form0").validate({ rules: { issueCheckBox: { selectNone: true}} });
Following is the JQuery code:
<script src="../../Scripts/jquery-1.4.4.min.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.validate.min.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.validate.unobtrusive.min.js"

I was wondering if someone could point me in the right direction:
How do I generate a custom error page with the error message and get it to mail me that error message?
Is there a good tutorial out there that someone could point me 2.
I have a UserControl which contains a TextBox and a CustomValidator. I would like to set the CustomValidator.ServerValidate to a method in the page that contains the UserControl I found this code which will allow me to dynamically set the custom validators validation function: cusvCustom.ServerValidate += new System.Web.UI.WebControls.ServerValidateEventHandler(MethodName);
The problem is that a string value won't work there. It needs to be a reference to the method. Is it possible to use reflection (or some other method) to get a valid reference to the parent controls method using only the string name of it? The reason I want to use the string value of the method name is so I can place the control on the page thusly: <uc1:TextBoxField ID="tbUserName" runat="server" CustomValidationMethod="ValidateUserName" />

I did some research and I found Type.GetMethod and MethodInfo but I can't get them to work. Primarily because I don't know the type of the parent control and can't figure out how to get it. EDIT: My code for matt-dot-net. As you can see it's almost an exact duplicate of your code. For whatever reason it does not work for me as I have it here. When I click on the button the page reloads and is the same. When I un-comment the one line though and click the button then I see the error message.
I have one doubt i.e i want to display the error message for the validator controls all the times regardless of whether one has entered a value or not. In my case i'm using few required field and custom validator controls.
By using Page.Validate() method i'm able to display the error message for all the controls , but this doesn't work in case the field has any value in it.
Please suggest if there is any workaround for this to display the error mesages for the fields with validator controls all the time.
I have a required validator that I check a textbox clientside, but then on post I check the database for values that have been used. I want to show the error in the RequiredFieldValidator when it post back. How do I do this?
View 1 RepliesI've got a booking form which allows users to pick dates. User clicks FromDate button which activates calendar control, they select date from calendar which then populates a textBox. I have a compare validator which checks that the SelectedDate is greater than the current date, if the SelectedDate is in the past then the validator fires error message. This works as fine, however, when the validator fires it disables the FromDate button so the user is unable to pick another date from the calendar as the focus goes to the TextBox which is being validated - how do I get around this? Here's the code:

i add asp.net file upload control as following
<asp:FileUpload ID="filesFileUpload" runat="server" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ErrorMessage="file types not supported"
ValidationExpression=".(zip|rar|jpg|gif|png|eps|ai|psd|pdf)$" ControlToValidate="filesFileUpload"></asp:RegularExpressionValidator>
and always when i upload file that match the reg expression it show the error .
I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here?
<asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="regExValActualCost"
ControlToValidate="txtActualCost"

I have textboxs that define requiredfield validator for them..I want when I click on button if users don't type text in textbox it shows popupmenu some thing like ModalPopupExtender that I can define div on it and it shows just this text" please fill required field".
View 1 RepliesI have the following RegularExpressionValidator on one of my pages:
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"
ControlToValidate="InKindTextBox"
ErrorMessage="The value entered for 'Cash' must be in a number format. Examples: 500.00, 500, $500, $50,000 or $500.00"
ValidationExpression="(?n:(^$?(?!0,?d)d{1,3}(?=(?<1>,)|(?<1>))(k<1>d{3})*(.dd)?)$)" >
But when it tries to validate it throws the error below from one of my dynamic JS pages.When I run this regex through regex texter it works fine. Am i doing something wrong here?
I've got two questions - first of all, why does .net render a javascript onclick event for asp buttons when there's a custom validator on the same page, and secondly, how can I get rid of the javascript?
It works fine when javascript is turned off, so I don't know what the point of it is. Here's a mini example:
<form id="form1" runat="server">
<asp:Button ID="Button1" OnClick="Button1_Click" Text="test" runat="server" />
<asp:CustomValidator ID="CustomValidator1" runat="server"
OnServerValidate="Stuff_Validate" EnableClientScript="false">
</asp:CustomValidator>
</form>
This will generate the following html for the button:
<input type="submit" name="Button1" value="test" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "", true, "", "", false, false))" id="Button1" />
Without the custom validator, it's:
<input type="submit" name="Button1" value="test" id="Button1" />
<asp:TextBox ID="txtDraftsmanName" runat="server" Width="200px" CssClass="inputtext" >
</asp:TextBox>*<asp:RequiredFieldValidator ID="RequiredFieldValidator7" runat="server" ControlToValidate="txtDraftsmanName" ErrorMessage= "Please enter Draftsman Name!! " Font-Bold="True" Font-Size="8pt" ForeColor="DarkRed" ValidationGroup="saveDraftsman"></asp:RequiredFieldValidator>
<asp:Button ID="btnSaveDraftsman" runat="server" Text="Save" onclick="btnSaveDraftsman_Click" ValidationGroup="saveDraftsman"/>
I am using Customvalidator control . I am giving client side validation function in it. On running it is giving error as: ValidationStream is not defined.
Following is the code:
<asp:CustomValidator ID="CustomValidator6" runat="server" ClientValidationFunction="validateDriveDate"
I created my custom validator in one project, something like that:
[Code]....
he composite control in another project. I added a reference of the custom validator project to the composite control project. I have a textbox in a composite control and I would like to validate this textbox by the composite control I created. But how can I do that? How can I create the custom validator instance that is linked to the custom validator I created?
I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
---------------------------------------------------------------------------------------------------
<sys.web>......<customErrors mode="On" defaultRedirect="~/Error.aspx"></customErrors>...</sys.web>
---------------------------------------------------------------------------------------------------
And even i tried in Global.asax page in Application_Error() method like below
Exception ex = Server.GetLastError();Response.Redirect("~/Error.aspx?errmsg="+ex.message);Server.ClearError();
And in my Error.aspx.cs page i have placed a label and i have written code like this
protected void Page_Load(object sender, EventArgs e) {
Label1.Text=Request["errmsg"];
}
But it is not getting redirected my error page and not displaying anything on it.
I've inherited some code (not mine- I swear!) which uses a session variable in the header of the HTML to determine which javascript file to link to.i.e.
<SCRIPT language="javascript" src="../JavaScript/<%=Session("jsFileName")%>.js"></SCRIPT>
It does work, except that it won't let me change to design view. It gives the message
"Could not open in design view. Quote Values differently inside a '<%... "value" ...%>' block."
Anyone got any suggestions as to a workaround, that doesn't involve a huge rewrite.
i have a complete form in my database as row for example name of the field ,is mandatory, sortid, regularexpression, datatype, maxlength , default value etc. So the form is completely dynamic.now i want to perform the client side validation on the form . What will be the best practice for doing that? like i have to see that if the field is mandatory check it for null and if not then leave it on the client side . i am thinking about setting hidden field for it .
