How can reload list after update item by Visual Web Part in Sharepoint 2016?

I created a visual webpart to update list data:

My code when click submit button:

protected void btnSubmit_Click(object sender, EventArgs e)
        {
          
            using (SPSite site = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList list = web.Lists["Employee"];
                    SPListItem item = list.Items.Add();
                    item["Title"] = txtName.Text;
                    item.Update();                    
                }
            }
        }

New Item had add to List, but List can't refesh.

I have to press F5, List will refesh.

How can reload list after update item by Visual Web Part in Sharepoint 2016?

Try to use Response.Redirect to refresh the List View Page like this:

 protected void Button1_Click(object sender, EventArgs e)
    {
    
        using (SPSite site = new SPSite(SPContext.Current.Web.Url))
        {
          using (SPWeb web = site.OpenWeb())
          {
           
            SPList list = web.Lists["Employee"];
            SPListItem item = list.Items.Add();
            item["Title"] = TextBox1.Text;
            item.Update();
          }
        }

      Response.Redirect("http://sp2016/sites/dev/Lists/Employee/AllItems.aspx");
      
    }
