Web Forms :: RequiredFieldValidator Failing For Some Users
Aug 24, 2010
Some times RequiredFieldValidator is failing to validate a calender textbox Field for date entry in the page so we receive a blank value in the email which the application sends and 1/1/1900 12:00:00 AM in the database for that corresponding control. It happened with a user who has got Internet Explorer and also the active Scripting is Enabled.
I have a web form that allows the user to upload a file to the web server, that file is then read into a database. This process works on my local pc, my dev box and one of my qa servers. I moved the code to a new QA web server and it doesn't work on that server, even though the web site is setup the same on all 3 machines. On the new server it was working at one time and then today it stopped.What could be causing me to get {access denied to folder c:websitefilesuploads} (which is the file I'm uploading to and then deleting and works on my local dev and one of my qa boxes
I have a menu on my Master.Page and all the colors are great, I have the ForeColor set to Yellow or white and it all looks gret on my local machine. BUT when I publish the site to the server I lose the forecolor. I looked on the server at the html and I see the forecolor="yellow".
What have I missed that it does not display the menu text in the color choosen?
I have an .aspx page with a gridview and a details view for looking up products. It is working perfectly. When I select "Details" on the gridview the details view accurately populates.I added an image named TagImageand need that image to display the correct one based upon the product changed when "Details" is hit. I'm using code behind and have checked my image directory string to make sure it is OK but the images do not display. Here is the vb.net code hehind I am using that successfully populates the details and was hoing it to display the picture:
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) AccessDataSource2.SelectParameters("ProdID").DefaultValue = _ GridView1.SelectedDataKey.Value.ToString()
I need to stop users users using the browser back button and potentially submitting an old version of a form.
I'm storing a guid in a session variable and also writing the value to a hidden form field and then checking the session value against the hidden field value if a user does try to navigate back and submit an old form.
If the form is submitted and the user wants to complete a new copy of the form then a new guid is generated both to the session and to the hidden form field. Now, if the user decides to hit the back button a few times to get the old form and tries to submit it again, the page checks the current guid in session against the guid stored in the form field and it finds a mismatch and prevents the form being submitted.
This works as expected in Chrome and Firefox, but in IE6, when the user hits the back button to view the old form, the new guid value appears in the hidden field of the old form! This means the user can submit the old form again, which we definitely do not want.
I create a new website in VS 2010 (VB .Net). I add a table, within it i add a textbox, a button and a RequiedFieldValidator. I set the RFV ControlTValidate property to the textbox. When i move(click or tab) away from the textbox, the RFV doesnt kick in the error message that i have set.
The RFV code is <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtEnterName" ErrorMessage="RequiredFieldValidator" InitialValue="0" ForeColor="#FF3300"></asp:RequiredFieldValidator> Texbox <asp:TextBox ID="txtEnterName" runat="server" Width="221px"></asp:TextBox>
I have following tag, I want to validate requirefieldvalidato runtim whenever user click on "Submit" button btnSubmit_Click event, how can I do this? Actually on my form I have 3-4 submit button for different purpose.On each buton I have set CauseValidaton=false,because some of the fields are initially hidden and depending on button click fields are visible.
Does the RegularExpressionValidator always need a RequiredFieldValidator?I see that when there is no input the RegularExpressionValidator is not working. Correct?
I am using ckeditor as my Rich Text Editor (RTE). This is an html element control and not an ASP control. I would like to use the RequiredFieldValidator (RFV) control to make this field required.
I cannot find any documentation stating that the RFV can be used like this. Can anybody tell me if this is possible?
Here's an example - notice that there is an html textarea element - how do I use RFV on this?
I am trying to make my ASP.NET (2.0) application to work on Server 2008 (IIS 7) but all validations are ignored. Many textboxes have requireedfieldvalidators that should require user entries but they are ignored. The same application runs on a bunch of Server 2003 with no problems like these. Is there a setting on Server 2008 IIS that has to be enabled/disabled in order for the validation to work?
I've recently finished building one of my first websites (and CMS) in ASP.NET but have came across a problem where a RequiredFieldValidator isn't working as it should do? I originally created the admin page to not require the RequiredFieldValidator, but now that I do need it the page won't acknowledge it's there. I have even set the field in the database to not accept nulls, but the query will still insert a null value into the database (SQL Server 2008 Express).
The TextBox that I'm referring to is "txtSectionTitle"
I am expecting the RequiredFieldValidator control to prevent a postback when the textbox is filled in with an incorrect data and the button pressed. What happens is that the validator displays an error message but a postback is fired.
Using MS article http://msdn.microsoft.com/en-us/library/ms998317.aspx, I created a web site to develop a forms authentication solution for our web app. The server is Win 2003 w/IIS 6 and the app is VB.NET. The web.config was updated for forms authentication and settingsappear below:
I have a FormView in which I have placed RequiredFieldValidators on some of the input controls in EditItemTemplate. But the validators all don't work when I hit the submit button.
I've tried FormView1.FindControl("RequiredFieldValidator1").Enabled = true but the compiler complains that 'System.Web.UI.Control' does not contain a definition for 'Enabled'.
Is there any way to create a RequiredFieldValidator directly from JavaScript and assing the validation to a new created textbox, also created from javascript? I know how to create a new textbox or input control, but the RequiredFieldValidator is giving me problems.
How do I validate RequiredFieldValidator/CompareValidator conditionally. I have aded equiredFieldValidator/CompareValidator on date textbox. I want that if textbox1="No" thne it should not validate or compare date text box, if textbox1="Yes" then it should validate.
Is this possible on form submit button or any other way?
We would like to display an image of a checkmark if the input was valid or an image of a stop sign and text if the input was not valid.I believe I need to do override the EvaluateIsValid method. I have never extended a control before and was hoping someone could point me in the correct direction.
