I have a DataGrid that I can edit value.
When the user click "Edit", some textboxes appears where it is possible to edit the text.
The problem is that I have two Date fields and when the user change the date, I want to check if the format is correct before sending the params, otherwise à get an error...
I give 400 points for a function who check the date format.
But in the ideal, I want to make a pop-up calender with the calendar component from the framework and when the user click in the TextBox the calendar appear and the value goes in the textbox. 500 points for this.
