Populate DropdownList from an ArrayList

Question

User1769015664 posted

In the code below, I see myArrayList contains several values in it and they are added to DataValueField and DataTextField but the dropdownlist is empty.

What did I miss?

                ArrayList myArrayList = ConvertDataSetToArrayList();
                foreach (Object row in myArrayList)
                {
                    ddlProdType.DataValueField = ((DataRow)row)["ProdNumber"].ToString();
                    ddlProdType.DataTextField = ((DataRow)row)["ProdType"].ToString();
                }

Try this

ArrayList myArrayList = ConvertDataSetToArrayList();
ddlProdType.DataSource=myArrayList ;
ddlProdType.DataValueField = "ProdNumber";
ddlProdType.DataTextField = "ProdType";
ddlProdType.DataBind();
