Dropdown gets cleared

Question

I have one asp.net application, in which i have one dropdown which is binded to dataset. But after selecting one item, the drop down gets cleared all the value, How we can resol

Answer 1

From your question if I understand correctly you dont want the dropdown list to rebind if it is populated. Also please check your viewstate, this should not be happening, unless you have disabled viewstate

 protected void Page_Load(object sender, EventArgs e)
{        
  if (!IsPostBack && ddlProduct.Items.count <=0 )
        BindProductDdl();

}
