I'm following this question for formatting timespan value in the gridview.

Format TimeSpan in DataGridView column

I'm diaplying only minutes value in grid as follows

DataGridViewColumn idleTimeColumn = myGridView.Columns["IdleTime"];
idleTimeColumn.DefaultCellStyle.FormatProvider = new TimeSpanFormatter();
idleTimeColumn.DefaultCellStyle.Format = "m";

This cell is editable, so when I enter 5 (that mean 5 min) in the cell, then it should take it minute, but it take it as day value (ie, 5.00:00:00).

I tried different values for format (mm,%m) but all these gives the same output.
