Question

I want to make my row to auto resize depending on screen size.
When I do this for column it really works:

grid.AutoSizeColumnsMode = System.Windows.Forms.DataGridViewAutoSizeColumnsMode.Fill;

But when I want to do same thing for row. I don’t have fill option.
I only have like

grid.AutoSizeRowsMode = System.Windows.Forms.DataGridViewAutoSizeRowsMode.AllCells;

How can I make my rows to fill my screen depending on it’s size?

Answer 1

You can use the AutoResizeRow method.

Per MSDN:

This method is useful if you want to control when a row resizes. The row height is adjusted only once per method call; if the contents of the row later change, the row will not automatically adjust. To resize all rows, use the AutoResizeRows method. To set the row to automatically resize whenever its contents change, use the AutoSizeRowsMode property.

There’s also a MSDN sample here.

You may want to look in to the RowTemplate property named Height. You can do your calculation as to when the screen size changes

EDIT:

You can put this in a resizing event, such as Form_ResizeEnd. YMMV on how the grid may perform with a large number of rows.

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    row.Height = 22; //your calculation based on the screen height
}

I believe you can use System.Windows.Form.Screens class, specifically Screens.PrimaryScreen.Bounds.Height if you want the primary screen’s height. It’s up to you to see what kind of size you want to maintain.
