I have no idea where to start. i tried DataTable but it didn't work.(This is an easy question :) )
I tried everything
{
var test = new DataTable();
test.Columns.Add("test");
test.TableName = "test";
test.Columns.Add("test");
comboBox1.DataSource = test.XXXX ;
}
Assuming you mean winforms, something like:
DataTable test = new DataTable();
test.TableName = "test";
test.Columns.Add("foo", typeof(string));
test.Columns.Add("bar", typeof(int));
test.Rows.Add("abc", 123);
test.Rows.Add("def", 456);
ComboBox cbo = new ComboBox();
cbo.DataSource = test;
cbo.DisplayMember = "foo";
cbo.ValueMember = "bar";
Form form = new Form();
form.Controls.Add(cbo);
Application.Run(form);
(in particular, SelectedValue should give you the 123 and 456 - useful for ids, etc)
ComboBox.Items property, unless you want data from a database or something.
DataTable dt=new DataTable();
dt.Columns.Add("Col1",typeof(int));
dt.Columns.Add("Col2",typeof(String));
dt.Rows.Add(1,"A");
dt.Rows.Add(2,"B");
comboBox1.DataSource = dt;
comboBox1.DisplayMember = "Col2";
comboBox1.ValueMember = "Col1";
You'll need to set the 'DataItemField' and 'DataValueField' to the appropriate column names in your datatable.
