If other than integer is entered in the textbox , it should say " please enter integer value ". ( With out using try catch block) Thanks in advance or you could use the numericupdown control :) The code here is worth checking for the future if you need to validate string entries, but for numeric values the Numeric Up Down control is much better. Add controls as shown in the figure below and set the properties of the controls as indicated in the table. The control is added to the form and displayed in the control tray in the Windows form in Design view. Now we will add the validations for the Date Time Picker controls which collects the Test Date information. Net, you can drag and drop the control from the toolbox. Please refer to the code listing provided at the end of the article.To display the dataset column error, invoke the Set Column Error method of the Error Provider.In a Win Form I'm doing initial validation in the Form.
