How to set specific ID for server controls in an ASP.NET Web Form that is using a MasterPage?

Is it possible to set a specific ID on an ASP.NET server control? Everytime I assign an ID and run the web form the ID changes.

For Example:

<asp:TextBox ID="txtName" runat="server"></asp:TextBox>

Gets translated into this:

<input id="ct100_ContentPlaceHolder1_txtName" type="text" />

I think this is do to me using master pages, but if so how can I be sure a control will have a certain ID(for javascript purposes). I placed the auto-generated id in my javascript and it is working, but I would prefer to have used the id's that I originally assigned them. Is this possible?

(This is for version:ASP.NET 3.5)

Solution

  • This is the way web controls ID's are in .NET prior to version 4.0. Version 4.0 introduces client IDs, which you can read about here.

    You can use somthing like this in your JS:

    var something = '<%= txtName.ClientID %>';
