Get_html is null or undefined

[Matt]

I'm trying something very simple. I'm using a custom validator that needs to check the length of the RadEditor. I'm using Q1 2013.

Any ideas???

I get this:

Error: Unable to get value of the property 'get_html': object is null or undefined

From this:

alert($find("#<%=RE_ChangeComments.ClientID%>").get_html().length);

Hi,

I have tried the following code to get the length.
JS:

alert($find("<%= RadEditor1.ClientID %>").get_html().length);

Note: No need of '#' to access the control in javascript.

Thanks,
Princy.
