Web Forms :: RequiredValidator Displays ErrorMessage At Its Place When Its Text Property Is Set To Empty
Jun 14, 2010
My understanding is that the ErroMessage is supposed to be displayed in a ValidationSummary control. My page does not have a ValidationSummary and I set the RequiredValidator's Text property to empty. I expected that nothing would be displayed when the validated control is invalid, but the ErrorMessage shows up at the place where Text is supposed to be. I am wondering if this is normal.
BTW, ValidatorCalloutExtender is used. Is this a cause?
Now I have to set the Display property to None to avoid any displaying anything. This is not a big deal, but I am curious.
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 have a table that displays data by year. The year headings and data selections are dynamically generated, so that the code does not need to be changed every year. Each cell has 2 validators on it, and the ErrorMessages for each validator needs to say the item and the year. On top of that, the validators are in FormView templates. I know how to set the ErrorMessage text in code behind, but I am wondering if there is a way to do it more efficiently. Right now for each cell I have to code:
string Year1_Text = ...code to set the year... RequiredFieldValidator Year1_Item1 = (RequiredFieldValidator) FormView1.Findcontrol("Year1_Item1RequiredFieldValidator"); Year1_Item1.ErrorMessage = Year1_Text + " Data Item Is Required"; CompareValidator Year1_Item1 = (CompareValidator) FormView1.Findcontrol("Year1_Item1CompareValidator"); Year1_Item1.ErrorMessage = Year1_Text + " Data Item Must Be Numeric";
With 5 years and 10 data items, that will be a LOT of code. Is there an easier way?
A web site project, 4 pages. First page just has button links to redirect to another page. When button link is cliced, the data is retrieved from SQL Server through stored procedures and they are in a class file. Able to call the procedures and pass the information through SET Properties and right before the page is displayed, checked and data is in the dropdownlist control then redirect to show page. The dropdowlist is empty, should I be using something different to show the page with the data? Have tryied REDIRECT and then fill dropdownlist and its still empty on displayed.
my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.

This is my scenario. I have a couple of content place holders on a Master page which by default are empty.Two of the content place holders are laid out side by side. I'll call one MainContent and the other SidebarContent. What I'd like to see happen is if a child page has content in the SidebarContent, the width of the MainContent should be adjusted accordingly.Is there a way to determine at runtime from the Master page if the calling child page has populated the SidebarContent?How do I go about this, if possible?
