Bind asp.net control's value to code behind function

Question

I have a hidden field that i want to bind to either a function on the page's code behind. I don't quite recall the exact syntax and i can't find the answer via Google. Is the code below correct? Thank.

print("<asp:HiddenField ID="dummy" Value='<%#Getdummy() %>' runat="server" />");

Is there a print function in asp.net? There are quotation marks inside the string with out escape sequence. — TheTechGuy

The code you've put looks pretty good ...

The two step process is ... add the hidden field to the markup

<asp:HiddenField ID="hdnId" runat="server" Value='<%# GetValue() %>'/>

Then create the specified method signature ...

protected string GetValue()
{
   return "something";
}

Hope this helps ...

One thing I would like to add, DataBinding is not supported by MenuItem so this method can not be used to enable/disable a particular item in a menu.

If you have the hidden field with runat=server, you could write code to assign value in the code behind (rather than in the markup).
