ASP.Net中的下拉列表，如何将其绑定到列表的属性

Question

I have drop down list which need to take all the values from the property Items which are stored in List< Person> . My var model is accepting all the information from my list .

string text=File.ReadAllText(@"...");

List< Person > model = JsonConvert.DeserializeObject< List< Person>>(text)

my drop down list code:

< asp:DropDownList runat="server" ID="dpdTags"  >

So how I can bind the needed data to the drop down list?

Answer 1

dpdTags.DataSource = model;
dpdTags.DataTextField = "PersonText";
dpdTags.DataValueField = "PersonValue";
dpdTags.DataBind();

Try use this

Answer 2

i think it is useful for you

List<Person> people = GetDataFromSomewhere();
DropDownList ddl = new DropDownList();
ddl.DataTextField = "Name";
ddl.DataValueField = "Id";
ddl.DataSource = people;
ddl.DataBind();
ddl.SelectedValue = (from p in people
                     where p.Selected == true
                     select p.Id).FirstOrDefault().ToString();
