The client-side editor will call the named JavaScript function on the page whenever a count state changes. This allows the developer to take appropriate action, such as perhaps enabling and disabling a button on the page.

The count state types that might have changed are:

• warning (count has exceeded the warning level)
• locked (count has reached or exceeded its limit)
• error (count has exceeded its limit)

The countStateChangeInfo object passed as an argument contains members for each changed state type which then contain a value member with its new value.

Set the property declaratively in the HtmlEditor tag:

CopyC#

CountStateChanged = "MyCountStateChangedHandler"

Page JavaScript function:

CopyC#

function MyCountStateChangedHandler(editor, countStateChangeInfo)
{
    if (countStateChangeInfo.error)
       MyDisableSaveButtonMethod(countStateChangeInfo.error.value);

       ...
}
