validation (datanotation ) for textboxes is not working when I populate dropdownlist in the same page ,when I click on submit button it was showing error instead of showing requirefields.when I comment on dropdownlist in html and actionresult in controller
and debug and run then validation are showing but when I enable dropdown it was redirecting to error.
Model:
publicclassClientProfScreen
{
[Display(Name =
"Client FirstName")]
[Required(ErrorMessage="Client FirstName
is Mandatory")]
publicstring CFirstName {
get;
set; }
publicstring CMiddleName {
get;
set; }
[Required(ErrorMessage =
"Client LastName is Mandatory")]
Description:An
application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.
Details:To enable the details of this specific error message to be viewable on the local server machine, please create a <customErrors> tag within a "web.config"
configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off".
What is the error? What is the expected results? Can you share all the relevant code including the model that has the actual data annotations? The dropdown does not have a validation message. Are you expecting a validation message for the dropdown?
I see that you updated your original post. I recommend reading the error message and following the instructions. This will give you the actual .NET error. Commonly when you see the actual error, you can fix the bug in your code. In the future I recommend
using standard .NET exception handling; try...catch blocks.

And if you set the <customErrors mode="Off"/> you can get the detailed errors, then you can modify your project based on this error message.

Hiemaak,
Try this code in your config file.
<system.web> <customErrors mode="Off"/> <compilation debug="true"/> <authentication mode="None"/> </system.web>And if you set the <customErrors mode="Off"/> you can get the detailed errors, then you can modify your project based on this error message.
Best regards,
Sam
