DataGridview Bind Collections

Bind Collections:

  • In C#, the DataGridView control supports the standard Windows Forms data binding model, so it will bind to a variety of data sources.
  • In most conditions, we will bind to a BindingSource component which will manage the details of interacting with the data source.
  • The BindingSource component can represent any Windows Forms data source and gives to us great flexibility when choosing or modifying the location of our data.

Code Explanation:

 c-sharp contrl bind output
  1. Here public string Name { get; set; } specifies to the accessor declare a Name property of type string can contain a get accessor, a set accessor, or both. Here in this example public int id { get; set; } specifies to the accessor declare a id property of type string can contain a get accessor, a set accessor, or both.
  2. Here this.Name = name; and this.id = id; specifies to qualify of the fields, such as name and id.
  3. List<student> items = new List<student>(); specifies to list of Student objects.
  4. Here in this example items.Add(new student("venkat", 1)); items.Add(new student("jln", 2)); items.Add(new student("arun", 3)); items.Add(new student("arun", 3)); specifies to add the student name and id.
  5. Here dataGridView1.DataSource = items; used to specify the data source of datagridview and the table which will be bind to. When we run the code a window will show with a datagridview that containing all the returning rows.
