Hi..
I want to validate a texbox control or dropdown when these controls are left empty or nothing is selected from dropdown while editing or inserting.
The error message could be like "This field cannot be empty". How can I achieve this?
Hello,
Which editors on which platform are you looking to add validation to?
In WebDataGrid for Dropdownlist. There is a text as "--none--" at the top of dropdown with value 0. If user select this and try to save then it will show an error message "This field can not be null or empty".
