I have a user control that i have registered to an aspx page. Now from the aspx page, i am trying to access one of the registered usercontrol's hiddenfield value in my aspx page using javacript using the below code:

tst = document.getElementById('control1$hdnField').value;

I looked into the page's trace, and i could see 'control1$hdnField'. Then why i am not getting its value in my aspx page. I have also ensured that the hidden field exits on the user control and has a default value set.

Please help.

Reset to default

I think what you have is the name of the field, what you need is the ID of the field, which would have a _ instead of $ as a delimiter, like this:

var tst = document.getElementById('control1_hdnField').value;

Since your hidden <input>, I'm pretty sure looks like this:

<input type="hidden" name="control1$hdnField" id="control1_hdnField" value="val" />

Tried this as well. But i am still getting 'Object Required' error.
No. I am using -- <asp:HiddenField ID="hdnField" runat="server" Value="Some Value" />
@flopdix - that's what it looks like in your markup...but when it gets rendered to the client the IDs get mangled a bit, prepending the naming container's it's in...unless you're using .Net 4, can you post what your rendered input looks like?
Ok. When i did View Source to my aspx page, i dont see hdnField in the markup. Is that expected? Because in the page trace, i am able to see Control1$hdnField.
No this script is in the aspx page. I am appending Control1/2/3 in the next iteration, so i wont have duplicate ids. I am still stuck, not getting, any ideas?
