Recaptcha Being Triggered From Masterpage Control?
May 17, 2010
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.

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.
Custom navigation template somewhere maybe?

I've downloaded the recaptcha.dll in both 1.0.1.0 and 1.0.4.0. When trying to render the control, I get the following exception: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

The solution to this, as provided by a quick Googling, is to use caspol.exe to add full trust to the recaptcha.dll assembly. C:\%path%caspol -af C:inetpubwwwroot\%path%in ecaptcha.dll At this point, I get the following error: ERROR: This assembly is not strong name signed Short of downloading the source code and recompiling it locally, is there any other way to get this working?

I have a MasterPage (MasterPage.master) with 2 child MasterPages (specialMaster.master and standardMaster.master). From the MasterPage.master I need to get at some of the controls in one of the children, specialMaster.master, say for example to hide certain
content if a session variable is not null.

I have controls and some has AutoPostBack set to true.
i.e
<asp:CheckBoxList ID="cblTest" runat="server" AutoPostBack="true"
OnSelectedIndexChanged="cblTest_SelectedIndexChanged" >
</asp:CheckBoxList>
How can I capture which control has triggered the autopostback event when it runs again in the Page_Load method.

This is an ASP.NET 3.5 app. The page has the following controls in this order: GridView with Select button enabled UpdatePanel, which containsA trigger pointing to the SelectedIndexChanged event of the GridView A child DetailsView that displays the record of the selected item in the GridViewUpdateProgressSelecting an item in the GridView triggers the UpdatePanel and the record displays in the DetailsView, as expected. However, since the GridView is outside of the UpdatePanel, the UpdateProgress doesn't display while the record is being retrieved. If the GridView is moved inside the UpdatePanel, everything works as expected but for several reasons it needs to be outside of the UpdatePanel for this app.
There are several articles about how to trigger the UpdateProgress display. Most involve using a button, which has an OnClientClick event, that can be used to trigger some javascript to change the display style of the UpdateProgress. Unfortunately, there is no client side event for the GridView so no way to trigger the javascript. Any ideas on how to display the UpdateProgress when a GridView item is selected? Here is a trimmed down version of the controls involved:

Most of the solutions found on the internet and in this forum made use of javascript triggered by a button. Pretty much all of the javascript followed along these lines:

I have found a couple of good topics here in the forum and wanted to see any other extra ideas for this control that I am making and trying to implement. So here is the basic information:
The control is going to display a SQL output in a bunch of label controls. The information is going to be coming from a gridview control where the field is going to be hyperlinked.
So I am wanting to set the "TargetControlID" property to the .ascx page load event.
now what I have found is that I can simply run the Popup.show(); function in the .cs file at the end of the page load, but I still have to place a valid control within the TargetControlID property. As you know, the property cannot be "null" and if I put in the control ID for something that is not valid, then it won't work either. So the only thing I can think of is tying it back to the overall control itself. Then I can always change it on the fly if needed, but I think I would not have to since it would fire on the page_load event...
Not sure if this is making any sense... Just understand that have to make this control go across several web pages that are already fully developed. I am just adding this in as new functionality...

I have a page that has a few requirements1. A Gridview that is dynamically populated (and refreshed at a regular interval) with a button control that is conditionally displayed 2. The button control should show a ModalPopup of a Panel that serves as a form 3. This Panel form contains a textbox populated with a value from the gridview and another dropdown control I can get 2 of these 3 requirements via a couple of different approaches (like 1+2 work, but 3 fails or 2 +3 work but 1 fails).The code pasted below is the closest I have gotten, and is actually my preferred method, and I was wondering if anyone could tell me why the ModalPopupTextBox1 is not rendered when ModalPopup button is clicked.If I place the Gridview1 outside of UpdatePanel1 (refresh controlled by Timer1), the ModalPopup Panel works as expectedMarkup: GridUpdate.aspx

I have a textbox txtPctDown inside an update panel. On textchanged, a sub is called that does a calculation and puts the result in to a label in a modal dialog. When the text changes, the sub is reached but the modal dialog doesn't appear. if I eliminate the UpdatePanel then everything works fine. I tried with an without using the textchanged as a trigger.
How do I get the modal dialog to appear when the text changes?

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?
At the moment, the only pseudo logic for this I can think of is?
'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)
'Try to find the user control as a child of the update panel

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 tried the following in the Page_Load
protected void Page_Load(object sender, EventArgs e) {
recaptcha.PublicKey = "<deleted for obvious reasons>";
recaptcha.PrivateKey = "<ditto>";
}
but I get an error stating "reCAPTCHA needs to be configured with a public & private key."
I also tried overriding the oninit method of the page and assigning the values there, but no joy.

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.

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.

A multiview with one View using a recaptcha and Modalpopup for response to a submit button within the ViewAn UpdatepanelI've spent hours and hours and hours searching around for any sort of solution that covers all of those without *some* sort of problem. If I put the menu inside, something won't work. If I put it outside, something else won't work. If I set 'conditional' or 'child-this-or-that' or whatever, *something* comes out to bite me. The recaptcha will vanish, or there are postbacks, or Modalpopup has gone agai
