C# – .net c# text box date with mask – setup

cdatetimeinputnet

I have a c# .net project and want an input text box for a date value. I want it to display a default value of mm/dd/yyyy and then allow users to enter valid dates.

I have tried using a masked text box but it doesn't like having the above format.

If i try and use //____ looks naff and so does 00/00/0000 and of course if you put in '0' like 03/11/2009 you get 3/11/29 because the 0's are deleted as part of the mask.

What is the best way to set up an input box like this, effectively with a mask, only allowing numbers, and validation (though at this point I am not so worried about that).

This seems so simple and isn't.

Try examining the the date in the OnChange event. Check the length of the text, adding / when appropriate.

Alternatively, see if the the DatePicker may be a better choice...

Jquery – Detect changed input text box

You can use the input Javascript event in jQuery like this:

$('#inputDatabaseName').on('input',function(e){
    alert('Changed!')
});

In pure JavaScript:

document.querySelector("input").addEventListener("change",function () {
  alert("Input Changed");
})

Or like this:

<input id="inputDatabaseName" onchange="youFunction();"
onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();"/>

C# masked text box

Why not just make life easier on yourself and create 4 separate data entry boxes? I personally always have difficulty with the single textbox approach if I type too quickly or need to back up.

Then you can validate each box for valid data as the user leaves it to ensure that they don't enter an incorrect value.

And if you have access to a numeric editing text box, you could even set min and max values (or you could implement this yourself).
