Hi Suresh Please use the below code snippet private void elementHost1_ChildChanged(object sender System.Windows.Forms.Integration.ChildChangedEventArgs e) { if (this.Parent == null || this.Parent.GetType() != typeof(Form1)) return; var frm = this.ParentForm as Form1; var label = frm.Controls[label1] as Label; var abc=elementHost1.Child; if (elementHost1.Child.GetType() == typeof(WpfApplication1.UserControl1)) { label.Text = User Control 1; } else label.Text = User Control 2; } Here Form1 is parent Form and code is written in source file of User control where ElementHost is available. Thanks Pravin
