I am successfully referencing other controls on my page like this:
var category = document.getElementById("<%= lstCategory.ClientID %>");
However, this does not work for my SAVE button.
var btn= document.getElementById("<%= btnSave.ClientID %>");
alert(btn)
Alert displays "null".
So, I displayed the source after the page is rendered. And this is the ID for the SAVE button: ctl00_PageContent_btnSave__Button
So, I did this:
var btn= document.getElementById("<%= ctl00_PageContent_btnSave__Button.ClientID %>");
But this fails at runtime with the following error:
'ctl00_PageContent_btnSave__Button' is not declared.
So, if the declared ID is different than the generated ID, how does one reference this control via Javascript??
Thanks.
