How to bind a jagged array into DataGridView?

Question

I have 2D array with different types of data(int, string, float).

How do i bind it to data grid view?

Or converting it to data View or BindingList or DataTab

You are not using a 2D Array, you are using a Jagged Array. A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes. A jagged array is sometimes called an "array of arrays."

To show a jagged array in DataGridView, you can first calculate the number of columns which you need and set ColumnCount property of grid. Then add rows using an overload of Add method of Rows collection of grid which accepts param object[]. For example:

object[][] data = new object[][]{ 
        new object[] {"kjslwe", 3, "w", 45, "erer", 643, "reew", "54", 56, 34},
        new object [] {23, "e", 1, "so", 123213, "ds", 343433}
};

var columns = data.Max(x => x.Count());         /* Calculate number of columns */
grid.ColumnCount = columns;                     /* Set column count of grid   */
data.ToList().ForEach(x => grid.Rows.Add(x));   /* Add rows                    */

In the above example, I also set these properties:

grid.AllowUserToAddRows = false;
grid.AllowUserToDeleteRows = false;
grid.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader;
