DataGridView Data Binding




There is a certain DataGridView in which columns are created manually, it is done something like this:

dataGridView.Columns.Add ("Column 1", "Heading 1");
dataGridView.Columns.Add ("Column 2", "Heading 2");
dataGridView.Columns.Add ("Column 3", "Heading 3");

How to make it so that when the data source is specified through the DataSource


dataGridView.DataSource = mySource;

Values ​​from desired properties of my source went to desired columns in DataGridView . For example, let’s say my data source contains properties A , B , C and let’s say I want:

  • property A was displayed in a column named “Column 3
  • property B in the column named “Column 2
  • and the property C in the column named “Column 1

P.S. Now, to achieve the desired result, you have to loop through the data source and add data from it to the DataGridView as follows:

dataGridView.Rows.Add ("Value for cell 1", "Value for cell 2", "Value for cell 3 ");

Answer 1, authority 100%

You need property DataPropertyName . Let me give you a small example. Let’s have a class that describes our data:

public class MyClass
    public MyClass (string a, string b, string c)
      A = a;
      B = b;
      C = c;
    public string A {get; set; }
    public string B {get; set; }
    public string C {get; set; }

Add columns to DataGridView:

dataGridView.Columns.Add (new DataGridViewTextBoxColumn
                       DataPropertyName = "A",
                       HeaderText = "Header 1"
      dataGridView.Columns.Add (new DataGridViewTextBoxColumn
                       DataPropertyName = "B",
                       HeaderText = "Header 2"
      dataGridView.Columns.Add (new DataGridViewTextBoxColumn
                       DataPropertyName = "C",
                       HeaderText = "Header 3"

Let’s create a collection and specify it as a data source:

var data = new List & lt; MyClass & gt;
                new MyClass ("1", "2", "3"),
                new MyClass ("4", "5", "6"),
                new MyClass ("7", "8", "9")
      dataGridView.DataSource = data;

That’s all.
