Control usrCnt= LoadControl("userControl.ascx");
usrCnt.ID = "usrCnt";
ASPxPanel1.Visible = true;
ASPxPanel1.Controls.Clear();
ASPxPanel1.Controls.Add(userCnt);

put these on the upper part of your usercontrol

private string _TextBoxValue = string.Empty;
public string TextBoxValue {
    get { return _TextBoxValue; }
    set { _TextBoxValue = value; }
}

then on your masterpage

usrCnt.TextBoxValue = TextBox1.Text;

For the quickest and dirty way is on your MasterPage

ViewState["TextBoxValue"] = TextBox1.Text();

and on UserControl, access ViewState["TextBoxValue"] to get the value.

Create a method for your usercontrol like SetText and then 

 usrCnt.SetText("textValue");

if it is your webusercontrol code behind

   public partial class WebUserControl1 : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        public void SetText(string theText)
        {
            this.Label1.Text = theText;
        }
    }

and if you've been added the control to the page in page call it as

 this.WebUserControl11.SetText(TextBox1.Text);
