Datagridview freeze columns or rows

1) column freezing
When the datagridviewcolumn. Frozen attribute is true, all columns on the left side of the column are fixed, and the fixed column does not move left or right with the scroll bar. This is useful for fixed display of important columns.

// Fixed the left column of datagridview1
Datagridview1.columns [1]. Frozen = true;

However, when datagridview. allowusertoordercolumns = true, fixed columns cannot be moved to non-fixed columns, and vice versa.

2) Row freezing
When the datagridviewrow. Frozen attribute is true, all rows above the row are fixed, and the fixed Rows do not move up or down with the scroll bar.

// The first two rows of the maid are fixed
Datagridview1.rows [2]. Frozen = true;
