I am using the captcha from recaptcha.net in my asp.net webform. The webform has a checkbox list which does an auto-postback. Now when I select any of the checkboxes, the pages is posting back and the captcha is refreshing too and gives me a new image and also throws the validation error,"Incorrect word, please enter".how to avoid the refrshing of the image(or captcha) on every postback of the page.I tried using other capctha controls from code project but I need an audio control for my captcha and have tried to use .net speech libraries to produce the audio, but could not succeed.So I am working with the recaptcha instead.
I have set of questions named as 1,a,b,c,d,2,3question '1' has radio button list like below. (a,b,c,d) and '3' are enabled only when user selects something apart rom "Never"number 2 is enabled only if user answers something from question 'd' (which is a checkboxlist)My problem is when user selects "A few times a year from 1 question" and some answer(for example second option as "Frequently" from number 3 which is a radio button list and now user selected differnt answer for question 1 (let say Montly) now answer to 3rd question autoamtically changed to first option in radio button list")
I'm inserting controls dynamicaly on my page on pre-init, thease controls are inserting based on a dropDownList that load its values from a database. These values are diferent to all clients.
If I insert my controls on pre-init then I have access to the value of radiobuttons, but this insert only 1 controls cause in pre render I don't have the selected value of dropDown.
If I insert my controls on on-load event then I have the value of my dropDownList control so I can be able to inser the correct number o controls but I don't have the value of my auto-postback radioButtons.
I make a project to solve this and I share the code of it here. (VB.Net 4.0)
How to delay the Auto postback for 10sec in textbox of asp.net.
I am filling the textbox by using autofill. I'm calling textchanged method in code behind, So I need to delay the Textbox for 10sec. Problem is when I entered single letter it is going for textchanged. so i need to delay the Autopost back
I have an asp.net listbox with 15 rows and auto postback when the selected item is changed. This works as expected but, when the form is re-loaded, IE scrolls the list so that the last selected item is now the top visible item in the list. This produces a confusing/jumpy effect for the users and makes the listbox more difficult to use than it needs to be.
Is there any way to get the list scroll position to stay as it was before the postback? i.e, if I select an item from the middle of the listbox, the listbox is scrolled to the same point after postback.
I have a simple page that displays a gridview once 3 criteria are inputed. I would like to add an submit button so that the date just not auto populate the gridview.
I have placed two radiobutton's on simple .aspx page. I didn't used any Update Panel or any javascript on that page also set both radiobutton's AutoPostback="True", But it's not responding as I want.
I have a dropdown listbox whose datasource is a dictionary.
When I have added items to the list and try to select an item from the list, the item I selected does not get the focus. And this comes when I changed the property autopostback to true.
Here are some of the codes which are relevant to it.
I'm having a pretty nasty problem with an auto-completing textbox. I want to initiate an asynchronous PostBack whenever a user selects an item from the auto-completed field and retain the value of the item, rather than the text inputted. This works perfectly when enter is pressed rather than a mouse click.
An example of my issue:
Someone goes to the page, and types 1000 into the textbox. The autocomplete displays 10002, 1000B, and 10000. The user clicks on 1000B and an asynchronous PostBack initiates. Instead of 1000B, the TextBox.Text value is still 1000. My assumption is that the textbox is initiating the PostBack before the value is actually getting assigned to it.
I presume only the Button server control in ASP.NET has AUTO POST BACK set to TRUE by default. All others need explicit setting of this property on need basis.
I have a CreateUserWizard where there are two plain WizardSteps, then the CreateUserWizardStep, then CompleteWizardStep. In the CreateUserWizardStep I would like to use a reCAPTCHA control. Obviously when I go to the first plain WizardStep the reCAPTCHA control is invalid. So when I click the Next button from the first WizardStep the form isn't valid and I can't progress. I'm not sure how to handle this situation.
Users are complaining they need to click the submit button. They want the option to use the Enter Key on the keyboard as well. How do I enable the Enter Key?
Below is my working code.
<asp:Content ID="Content1" ContentPlaceHolderID="ContentSpeeD" Runat="Server"> <p>Prove yourself Human by passing the Captcha Test.<br> Please type the two words below.<br> The purpose of this test is to help prevent our site being spammed.</p> <recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="pubkey" PrivateKey="privkey" /> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" /> <br/> <asp:Label Visible=false ID="lblResult" runat="server" /> </asp:Content>
When I select the Search By dropdown, an additional gridview is created on auto-postback.I will ad a visual and code as soon as this is accepted for review.
I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.
I have a simple online web system where it possible for the visitors to "play around" with the system. They can like create categories and products and so forth. Everything they create are stored into a database.
What I want is to be able to reset this database with my default values (table data) every n hours.
So for example if we have a bunch of users that have played with the system and created new things. Then I want to be able to make some kode that deletes all data in the tables in this database and fill it with default data. The default data can come from a backup file, or another database with same tables structure or whatever.
I want this task to be done every day at 12 pm or every n hour.
Is this possible (by forexample scheduled webservice tasks or just something as long as it is simple).
I am using recaptcha in an ASP.NET 3.5 application and for some odd reason the ErrorMessage property is not working. Below is my code
<recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="*******************************" PrivateKey="*******************" Theme="white" ErrorMessage="This is an typo error" />
When the typed text doesn't match with the recaptcha image text it still shows the default error message "Incorrect. Try again." instead of my custom error message. What could be the reason for this strange behavior
I've implemented reCAPTCHA following the instructions on this site:[URL]However I am unable to get it to render on my lightbox. It renders as below when i check with firebug.
<noscript> <iframe src="http://www.google.com/recaptcha/api/noscript?k=6Lctg74SAAAAADV4UAfyRdEUdZi_FGc4PCqA7LEn" width="500" height="300" frameborder="0"> </iframe><br /><textarea name="recaptcha_challenge_field" rows="3" cols="40"></textarea><input name="recaptcha_response_field" value="manual_challenge" type="hidden" /> </noscript> Note that when i look in firebug the < and > display as the text "& lt;" and "& gt;" (without the space)
Let me know if there's any additional information required to help with this problem.
I'm implementing the recaptcha control from google.
I built a simple c# test project from their example and all works. Now, instead of having the PublicKey and PrivateKey in the aspx page, I'd rather assign these values at run time as they will most likely be pulled from either the web.config or a database table.
I have a master page which contains a Login control so that the user can login/logout from any page. However, a couple of content pages require a Recaptcha control. This causes problems because when I try and log in on a page that has the Recaptcha control, the system expects me to enter the words. I'm aware of the lack of validation groups in the Recaptcha control, and the fact that you can't have multiple forms on an ASP.NET page. Is there a way to work around this? A 'hacky' way I can think of, is in the "Login" event, check the page for a Recaptcha control. If one exists, then disable it, otherwise continue. However, that just seems quite inefficient especially when there are quite a few pages and most won't have a Recaptcha control.
The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test).I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.
