How to access parent form control from Wpf hosting element

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
