Limiting Multiline textbox

[Neven Klofutar]

Hi,

Is there a way to limit this field, because "maxlength" seems to be working
only for singleline ?

thanx, Neven

This is more of an HTML issue than a ASP.NET issue. A multiline textbox
renders as a TEXTAREA HTML element. This element has no maxlength property.
To limit the length of a multiline textbox you have to do this in the
postback handler. You can also use a java script function to validate the
length of a field client side.

I thought so, but why putting this property under textarea ...

Thanx, Neven

Just use a regular expression validator to limit the length of the
string value of the text area.

(from http://dotnetjunkies.com/WebLog/seichert/archive/2003/07/28/541.aspx)

<asp:RegularExpressionValidator ControlToValidate="Content"
ValidationExpression=".{0,255}" Text="*" ErrorMessage="Please limit
the length of the content entered to 255 characters." Runat="server"/>

Hope that helps,

I don't think the MaxLength attribute works with TEXTAREA elements.
You could try using JavaScript instead.
