Make control public in designer generated file - asp.net

Question

It there any way to tell the ASP.NET .designer.cs code generator to create public controls instead of protected?
.master.designer.cs file:
/// <summary>
/// btnLanguageEN control.
/// </summary>
/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
/// </remarks>
protected global::System.Web.UI.WebControls.LinkButton btnLanguageEN;
.master file:
<asp:LinkButton runat="server" ID="btnLanguageEN" OnClick="btnLanguageEN_Click" Text="ENG" />
Why I need it? I am trying to access to master page controls from child page:
.aspx file:
<%# MasterType TypeName="www.MainMaster" %>
.aspx.cs file:
Master.btnLanguageEN.Text = "123";
Here I receive an error stating that btnLanguageEN is protected.

Answer 1

Rather than modify the designer generated code, reference the control through the Page's Master property using the FindControl method.
You'll need to add the following directive to the top of your child page (if it's not already there) to reference the master page:
<%# MasterType virtualpath="~/Masters/Master1.master" %>
Then, in your child page's code behind, you can do things like the following.
void Page_Load()
{
// Gets a reference to a LinkButton on the master mage.
// a ContentPlaceHolder
LinkButton mpLinkButton = (LinkButton) Master.FindControl("btnLanguageEN");
if(mpLinkButton != null)
{
mpLinkButton.Text = "123 - Labelled by Child Page";
}
}

Create a strongly typed reference to your master page by including this on your ASPX page.
<%# MasterType virtualpath="~/Masters/Master1.master" %>
On your Master Page, create a property. This will make the control available from other classes..
public Button btnLanguageENMaster
{
get {return btnLanguageEN;}
private set;
}
Then from your regular page code behind you can do this...
Master.btnLanguageENMaster.Text = "Hello, world!"
