如何在数据网格视图中显示项目列表 c#

Question

I have a Windows Forms Application I am working on and am using the language C#. I have a list of items that I want to put into a Data Grid View. Here is the code I tried:

        List<double> m2 = T.ALLDATIX;
        var list = new BindingList<double>(m2);
        var source = new BindingSource(list, null);

        dataGridView1.DataSource = source ;

Answer 1

Did you try:

var bindingSource = new BindingSource(){ DataSource = m2 };
dataGridView.DataSource = bindingSource;

See docs for reference .

Answer 2

Can you try this? I assume that the problem is, that the dataGridView does need objects (containing properties) to work properly.

// Define a container class
class Container
{
   public double Data { get; set; }
} 

// convert list of double to BindingList of Container Objects
var list = T.ALLDATIX.Select(q => new Container { Data = q }).ToBindingList();

// Assign data
grid.DataSource = new BindingSource(list, null);

THIS LINE SOLVED THE PROBLEM

       this.dataGridView1.DataSource = m2.Select(k => new { Value = k }).ToList();

Answer 4

Probably you should use the datasource. Try something like this:

dataGridView.DataSource = list.ToList();
