I have a textbox, with a dropdownextender. I want the dropdownextender to show the drop down list contents when the user clicks on an image button?

I can get the textbox and the dropdownextender to work properly (without using code behind).

What do I do on the ImageButton's client click to show the dropdown contents?

Hi,
From this we can't conclude anything, but I want to suggest you to use jquery datetimepicker plugin for your problem! It is fully configurable and easy to integrate into your code (one line of code only)! All details you can find here!

Yes, my question is how do I get the ImageButton click to show the dropdown list contents ?

I want to use the button to save the user from hovering and then clicking the arrow.

Try this Code

JavaScript

<script type="text/javascript">
  
function toggleImageBtn(elemID) {  
  
   var pnl = document.getElementById(elemID);  
  
   if (pnl.style.display == 'block' || pnl.style.display == '')  
      pnl.style.display = 'none';  
   else  
      pnl.style.display = 'block';  
  
   return;  
}  
</script>

ASP.NET

<asp:imagebutton runat="Server" id="ImageButton1" onclientclick="toggleImageBtn('hiddenIntervals')" imageurl="~/images/time.png" alternatetext="" enableviewstate="False" causesvalidation="false" xmlns:asp="#unknown" />
