Hi Jeff: That will set the box size but I think it will not limit the
characters you can enter in the box. This is a multi-line text area. You can
set the size in rows anc columns but you can type any number of characters into
the display area, at least that is the way I think it works. There is a
MaxLength property, again I think that is what it is called, but that only
works for single line and password TextBoxes. It can be checked server side in
the code behind file but that doesn't tell the user that they have exceeded the
number of allowed characters while they are typing. I was thinking of a hot key
that, when pressed, would tell the user the max characters allowed and how many
they have used or how many they have left. I have never seen anything like that
so I was guessing others had solved the problem in some other way.
By the way, if you think I am wrong about the Rows and Columns or the Input
element size limiting how many characters can be entered let me know and I will
check it out but I remember typing more characters in a box than the displayed
box size would allow but that was a year or so ago so my memory might be faulty.

I know you want to do it with JAVAScript, but there are simpler ways:
1. Use rows and cols for the size. Set rolws equal to 1 and cols to 10.
2. Use a Input tag with a size attribute of 10.
See if that will work for you Rick.

Hi: I have the following code to check the TextArea to make sure a user
doesn't enter more than 10 characters. It works but badly with a screen reader.
If I enter 11 characters it will keep typing but no more characters are added
to the box. Then when I try to open it again I just hear a ping with left and
right cursor. Up and Down cursor reads the 10 characters but I can't delete
anything using the delete key, I am locked out of the box.
How do you JS folks handle a MaxLength situation that works well with
screen readers? Here is the code I am currently using.It took some work to get
it working but I am not happy with the way it reads for screen reader users.
Overview:
<textarea name="ctl00$MainStarTrekContent$FormView1$OverviewTextBox"
rows="10" cols="20" id="ctl00_MainStarTrekContent_FormView1_OverviewTextBox"
onkeydown="if(this.value.length>=10) return false;"
onkeyup="if(this.value.length>=10) return false;"
style="width:800px;">abc</textarea>
<br />
Note: These are bound TextBoxes inside a MS ASP.net FormView if that
colors your solution.
Thanks for any Ideas:
