List<MyClass> as datasource for DropDownList?
12,687
For web based ASP.net
You need to specify the drop down lists datatextfield
and datavaluefield
properties.
MyDropDownList.DataSource = myList;
MyDropDownList.DataTextField="Name";
MyDropDownList.DataValueField="ID";
MyDropDownList.DataBind();
For win form
You need to specify the displaymember
/ valuemember
properties.
Just noticed this is a winform application try this:
MyDropDownList.DataSource = myList;
MyDropDownList.DisplayMember = "Name";
MyDropDownList.ValueMember = "ID";

I have a simple Class with ID and Name on it which I would like to link to a DropDownList but it seems that
myDropDownList.DataTextField = "Name";
andmyDropDownList.DataValueField = "ID";
are not accessible or available.UPDATE: I am using winforms
public class Test { public int ID { get; set; } public string Name { get; set; } } List<Test> myList = new List<Test>() { // bla bla bla some entries bla bla bla you got the point. }; myDropDownList.DataSource = myList;
I know I could override ToString but that would not help me with the value of each entry on the list.
Are there any other options to print the Name on the dropdownlist while having another property as the value (ie: printing Name while having the selected value or item as the ID) ?

LoganS almost 13 years@Prix no problem, I'm glad you solved it. And no it wasn't a silly question, it was quite valid and something that other developers may forget :) or beginners may never know.
