Changing the Value of Label

[mathewgk80]

Hi all,

I am trying to do an assignment.

I have a textbox. The size of the textbox is 20;

I have a label. The text of the label is 20 by default.

When i enter a letter say 'a' into the value of the label should be changed to 19.

Likewise, how many letters i enter into the text box, the value of the label should be decreased..

I need a keypress event that is when a key is pressed on the keyboard,the value of label should be decreased.

I am using asp.net, c#.net and Javascrpt.
Please help me...

Thanks.

Mathew.

Check out the .NET article on how to check if a TextBox contains a number...this will give you an idea of how to use JavaScript to do this for you.
