Custom http://www.c-sharpcorner.com/uploadfile/manas1/displaying-dynamic-error-message-in-asp-net-custom-validator/ validator doesnt show error message but shows server error P: n/a pmud Hi, I am using a compare validator in asp.net application(c# code). This Custom validator is used for comparing a value enterd by the user against the primary key in the SQL database. custom validator IF the VALUE ENTERED BY THE USER EXISTS IN THE DB , then THE ERROR MESSAGE OF THE COMPARE VALIDATOR SHOULD BE DISPLAYED. For this, I used the reference artiicle "http://msdn.microsoft.com/library/default.asp?url=/library/en- us/vbcon/html/vbtskvalidatingagainstvaluesindatabase.asp" . But it doesnt work i.e, when i enter a value(which already exists in the database) in the text box & hit validator not showing submit, the Validation summary DOESNT SHOW ERROR MESSAGE. Instead, I get the error as:: Server Error in '/NEW' Application. Violation of PRIMARY KEY constraint 'PK_FormFields'. Cannot insert duplicate key in object 'FormFields'. The statement has been terminated. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. RATHER THAN THE USER BEING SHOWN THIS Server error page, I want the CUSTOM VALIDATOR TO CHECK IF THE VALUE ALREADY EXISTS IN THE DATABASE,then THE VALIDATION SUMMARY SHOULD SHOW ERROR. My code is:: private void CustomValidator2_ServerValidate(object source,System.Web.UI.WebControls.ServerValidateEve ntArgs args) { DataView dv= new DataView(); dv=dsValidate1.Tables[0].DefaultView; string asi; args.IsValid=true; foreach(DataRowView datarow in dv) { // Extract asi from the current row asi = datarow["Alias"].ToString(); // Compare asi against user's entry if (asi == args.Value) { args.IsValid = false; } } } Any help is appreciated.
