Dear all
My team leader asked me if there is a possible way to create a user control that takes date values only with the format "dd/MM/yyyy" and prevent any other value or format to be entered (either by keyboard or paste) in this text box; by using VB.NET.
Can you help me please

Use Masked control.

Ok, but in link (How To Disable Right Click In C# Textbox); it is cancelling paste if it fired from the mouse, but what about if (Ctrl + v) or (Shift + Insert) pressed?

thatraja 17-Dec-11 11:58am

What about last 2 links? So you don't want to use Google, right?
:(

fadi77_net 17-Dec-11 14:27pm

No, it is not like what you understand, I searched in google but I did not find any result, I want to check if the value is date value then accept paste, else cancel paste.
paste should be by 3 ways:
1- by mouse
2- by pressing Ctrl + V
3- by pressing Shift + Insert

thatraja 17-Dec-11 14:32pm

OK, from my answer you got solution to disable mouse right clik
Also I gave you links for disabling keypress. Now you need to find implement that based on key code values of keys(ctrl + v & shift + insert). Go ahead.

This discussion does not worth time. This request is totally inappropriate. OP get a reasonable advice about date time picker. If this is not good enough, why negotiating? OP can do whatever they want, but without our help. Let's have some decency.

Solution 1

Yes - don't use a text box.

Have a look at this: http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/Calendar/Calendar.aspx[^]

If you are using a windows app (as you state in your reply to thatraja's solution, then a Calender is wrong. Use a DateTimePicker instead - it can act like a text box and not show a drop down, but it has two advantages:
1) It displays in tyeh users preferred date format, rather than your team leaders.
2) It means you don't have to do any validation to ensure the user has entered a real date, rather than 99 99 9999, or 31st February.
If your team leader absolutely requires a text box to do this, he is an idiot.
Or this is your homework.

My 5, but not for an answer, for a comment.
This is very inappropriate, when a person not really responsible for a solution asks a question and then impose a limitation referring to some "authority".

This is the abuse. Why should we waste time for such question? Let this "team leader" call us, and let OP resolves their problems about relationships by himself.
