I'm getting a message that btnSelect is inaccessible due to protection level when I run this page.  What do I need to change to get rid of this error?

Make sure your base class that contains the btnSelect in public, or internal, and btnSelect is also public, internal...


Hope helps...

This is the way the button is declared, which is done by C#:

public class collaboration : System.Web.UI.Page
      {

            protected System.Web.UI.WebControls.Label lblMessage;
            protected System.Collections.Hashtable objError = new Hashtable();      

            protected System.Web.UI.WebControls.DropDownList ddlState;
            protected System.Web.UI.WebControls.Table tblResults;
            protected System.Web.UI.WebControls.DataGrid dgTerritory;
            protected System.Web.UI.WebControls.Label lblSearchTotal;
            protected System.Web.UI.WebControls.Button btnSubmit;
            protected System.Web.UI.WebControls.TextBox txtName;
            protected System.Web.UI.WebControls.TextBox txtTerritory;
            protected System.Web.UI.WebControls.Button btnSearch;
            protected System.Web.UI.WebControls.Label lblTotalRecords;
            protected System.Web.UI.WebControls.Button btnSelect;
            protected System.Web.UI.HtmlControls.HtmlInputHidden hidCheckBox;
            protected System.Web.UI.WebControls.DataGrid dgBasket;
            protected System.Web.UI.HtmlControls.HtmlTableRow trBasket;
            protected System.Web.UI.WebControls.Label lblConfirmVenue;
            protected System.Web.UI.WebControls.Button btnNext;

Are you saying that the button shouldn't be protected?

Yeah, probably thats why you can't use it. Try put it internal or public....
This should solve the problem.

That did not work.  I'm still getting the error with this code:

public class collaboration : System.Web.UI.Page
      {

            protected System.Web.UI.WebControls.Label lblMessage;
            protected System.Collections.Hashtable objError = new Hashtable();      

            protected System.Web.UI.WebControls.DropDownList ddlState;
            protected System.Web.UI.WebControls.Table tblResults;
            protected System.Web.UI.WebControls.DataGrid dgTerritory;
            protected System.Web.UI.WebControls.Label lblSearchTotal;
            protected System.Web.UI.WebControls.Button btnSubmit;
            protected System.Web.UI.WebControls.TextBox txtName;
            protected System.Web.UI.WebControls.TextBox txtTerritory;
            protected System.Web.UI.WebControls.Button btnSearch;
            protected System.Web.UI.WebControls.Label lblTotalRecords;
            public System.Web.UI.WebControls.Button btnSelect;
            protected System.Web.UI.HtmlControls.HtmlInputHidden hidCheckBox;
            protected System.Web.UI.WebControls.DataGrid dgBasket;
            protected System.Web.UI.HtmlControls.HtmlTableRow trBasket;
            protected System.Web.UI.WebControls.Label lblConfirmVenue;
            protected System.Web.UI.WebControls.Button btnNext;

I saw in your page code that you set the button property "enabled = false".

And thats why probably in the initialize component method, it can't be accessed.

Try set the enabled property to false in you C# code, on PageLoad or other init method that you have.

You get the error when you compile the page ( at a certain line), or when you run the page?

That wasn't the problem.  I found it.  I had for some reason this in my code:

private void btnSelect_Click(object sender, System.EventArgs e)

which I changed to

public void btnSelect_Click(object sender, System.EventArgs e)
