User197255166 posted

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;
        
        }
