How to put a character limit on a textarea?

Hi Pravin,

I'm 98% sure that a custom component that uses the %ZEN textarea as a superclass, adds a "maxlength" Property, and overwrites the %DrawHTML() method is the best (only?) way to go. Here's a code smippet that worked (but you likely already have such code :-)).

<codesnippet>

Class ZenApp.Component.TextArea Extends %ZEN.Component.textarea 
{
........

/// Maximum number of characters allowed within the textarea control.
Property maxlength As %ZEN.Datatype.integer(MINVAL = 0);

Method %DrawHTML()
{

.....

&html<<textarea id="#(..%MakeId("control"))#" class="#(..controlClass)#" #(..%Attr("title",..title))# #(..%Name())# #(..%Attr("cols",..cols))# #(..%Attr("maxlength",..maxlength))# #(..%Attr("rows",..rows))# #(disabled)# #(ro)# #(spellcheck)# #(tStyle)# #(..%Attr("tabindex",..tabIndex))# #(..%GetEventHandlers())#>#(tValue)#</textarea>>
}
 

</codesnippet>

Hope this helps.
