Determine number of characters entered into textbox with C#

Question

Hi I was wanting to display the number of characters entered into a textbox and I want it to update as I type how can I go about this?

Here is what I have:

Answer 1

How about

int jj = textBox1.Text.Length;

Or am I missing something?

Answer 2

you can use the OnTextChanged event of the Textbox on the client side in Javascript and compute the increment from.

Answer 3

TextBoxobject.Text.Length will give you the length of textbox value.

Answer 4

The text of the text box will be a string, so it has a Length property, i.e.:

textBox1.Text.Length
