No Validation Messages when Disabling & Enabling ASP.Net Validator in Javascript

posted on 04 March 2010 in programming

Need to validate a form field based on the value of another field in ASP.Net? The .Net Framework provides a javascript function to do just that:

ValidatorEnable(val, enable)

This function takes the validator control (val) and a boolean to determine whether it should be enabled or disabled. The problem with this function is that it triggers the validator to validate itself immediately, showing any validation error messages before the user has submitted the form, which may not always be want you want.  The alternative is to set the validator’s enabled property to trigger this validator to validate itself when the user submits the form, and by using the Page_IsValid variable you can test whether the user has triggered a validation or not, then use ValidatorEnable function only after the validation has occurred when the user expects to see validation messages.

Create a PDF using the .Net ReportViewer control

posted on 25 November 2009 in programming

Need to generate a pdf programmatically in dot net? You could purchase an HTML to PDF converter and worry about getting the page to format nicely for paper, or you could use the freely available ReportViewer control from Microsoft.

SSRS requires a Report Server to publish reports to so they can be useful, however they also offer a ASP.Net or Windows Forms component called the ReportViewer which we can use in our code without the need for any SQL database to generate reports, and these reports can be saved as Excel files, PDF’s or images.
