Array of DataGridViews in C#

I am working on a program that contains multiple DataGridViews on multiple tab controls. My DataGridViews have a lot of initial formatting done to them at runtime. For example, row 0 and 1 are my first set of "headers" which are read only cells with color and font formatting. Rows 2 and 3 are for data entry with color coding based on values entered. Then, this row organization repeats for rows 4, 5, 6, and 7, then, so on.

I do not want to have to repeat all the setup and formatting code for all the other DataGridViews. Is there a way to create an array of DataGridViews so that I can loop the setup and formatting code?

DataGridView[] subFrames = new DataGridView[16];

The above compiles, but how does one use this? I cannot name a DataGridView control on my form subFrame[0]. Do I have to create the control and define placement, etc in code to do this? Or is there another way?

If you're generating the DataGridViews dynamically then you can use exactly the approach you propose. Instances of controls on a form are objects in C# like any other, so you can hold a reference to those objects in an array.

Not knowing much of your code, this is a bit of a contrived example. But consider this pattern:

public class Form1
{
    private DataGridView[] subFrames = new DataGridView[16];

    // other code

    private void BuildGrids()
    {
        this.DataGridView1 = BuildFirstGrid();
        subFrames[0] = this.DataGridView1;
        // continue for the rest of the grids
    }

    private void StyleGrids()
    {
        foreach (var grid in subFrames)
            ApplyStyling(grid);
    }
}

The code you're looking to consolidate for this specific question would be in ApplyStyling(), essentially transforming each grid as you describe.
