Setting Uniqueid for hidden fild in asp.net

i am trying to set UniqueID for a hidden field control .its throwing me error

The 'UniqueID' p开发者_如何学JAVAroperty is read-only and cannot be set. 

How to solve this issue ??

my code

 <asp:HiddenField ID="hSequence" runat="server" UniqueID="hSequence" />  

If you define the HiddenField like this:

You can access identifiers from the Server Side like this:

hSequence.Value

or

  Request.Params[hSequence.ClientID]

Q: You can not to consider to use the ID property as research key for your asp.net controls?

This identifier is generated automatically when a page request is processed.you can just Get it not Set

public virtual string UniqueID { get; }

also see Control.UniqueID Property

The UniqueID is auto-generated based on the control hierarchy. You cannot set it. Why do you want to do that anyway? Perhaps we can help you with another solution.
