Sometime you need to disable the ability for users to sort on a column and you can easily do this by setting the DataGridViewColumn.SortMode property to desired value.
Here are the steps for achieving this behavior:
1) Righ click on the DataGridView
2) Choose the Edit Columns option
3) Select the column that you want to disable sorting logic for
4) Set the SortMode property to NotSortable
Default behavior of a DataGridViewComboBoxCell is that it doesn't support typing into the cell.

If a DataGridView control on your form contains an image column and cell and need to display null values, it will be replaced with the standard "X" image.
If you need different behavior, i.e. to make sure that no image will be displayed, you have to change the NullValue property of the column to "null".
Here is the code example demonstrates setting the NullValue for an image column:
this.dataGridViewImageColumn1.DefaultCellStyle.NullValue = null;
By default, text in a DataGridViewTextBoxCell does not wrap. This can be controlled via the WrapMode property on the cell style (e.g. DataGridView.DefaultCellStyle.WrapMode).
Set the WrapMode property of a DataGridViewCellStyle to one of the DataGridViewTriState enumeration values.
The following code example uses the DataGridView.DefaultCellStyle property to set the wrap mode for the entire control.
this.dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
