  Devexpress Combobox After Change postback

  Aug 12, 2017 08:31 PM|Aliyilmaz|LINK

  Hi everyone,
  
  I will list the gridview according to the category I want to do. But when choosing categories, there will be no page postback. How can I do that
  
  

  Code Behind

  private void Kategori()
          {
              Entities uye = new Entities();
  
              ASPxComboBox1.TextField = "Dil";
              ASPxComboBox1.ValueField = "ID";
              ASPxComboBox1.DataSource = uye.Diller.ToList();
              ASPxComboBox1.DataBind();
          }
  
          
  
         protected void ASPxGridView1_DataBinding(object sender, EventArgs e)
         {
             Entities uye = new Entities();
              var slider = (from v in uye.Slider
                            select new
                            {
                                v.ID,
                                v.AdminID,
                                v.SliderAciklama,
                                v.SliderBaslik,
                                v.SliderYol,
                                v.Tarih,
                                v.Diller.Dil,                       
                                v.Ok,
                                v.Sira
  
                            }).ToList();
  
              ASPxGridView1.DataSource = slider;
          
          }
