Examples

The following code example illustrates the use of this type.

private void dataGridView1_ColumnHeaderMouseClick(
    object sender, DataGridViewCellMouseEventArgs e)
{
    DataGridViewColumn newColumn = dataGridView1.Columns[e.ColumnIndex];
    DataGridViewColumn oldColumn = dataGridView1.SortedColumn;
    ListSortDirection direction;

    // If oldColumn is null, then the DataGridView is not sorted.
    if (oldColumn != null)
    {
        // Sort the same column again, reversing the SortOrder.
        if (oldColumn == newColumn &&
            dataGridView1.SortOrder == SortOrder.Ascending)
        {
            direction = ListSortDirection.Descending;
        }
        else
        {
            // Sort a new column and remove the old SortGlyph.
            direction = ListSortDirection.Ascending;
            oldColumn.HeaderCell.SortGlyphDirection = SortOrder.None;
        }
    }
    else
    {
        direction = ListSortDirection.Ascending;
    }

    // Sort the selected column.
    dataGridView1.Sort(newColumn, direction);
    newColumn.HeaderCell.SortGlyphDirection =
        direction == ListSortDirection.Ascending ?
        SortOrder.Ascending : SortOrder.Descending;
}

private void dataGridView1_DataBindingComplete(object sender,
    DataGridViewBindingCompleteEventArgs e)
{
    // Put each of the columns into programmatic sort mode.
    foreach (DataGridViewColumn column in dataGridView1.Columns)
    {
        column.SortMode = DataGridViewColumnSortMode.Programmatic;
    }

    If oldColumn IsNot Nothing Then

    Else
        direction = ListSortDirection.Ascending
    End If

    ' Sort the selected column.

End Sub

Private Sub dataGridView1_DataBindingComplete(ByVal sender As Object, _
    ByVal e As DataGridViewBindingCompleteEventArgs) _
    Handles dataGridView1.DataBindingComplete

    ' Put each of the columns into programmatic sort mode.

Remarks

The DataGridViewCellMouseEventArgs class provides data for the following DataGridView events:

Constructors

DataGridViewCellMouseEventArgs(Int32, Int32, Int32, Int32, MouseEventArgs)

Initializes a new instance of the DataGridViewCellMouseEventArgs class.

Properties

Button	Gets which mouse button was pressed. (Inherited from MouseEventArgs)
Clicks	Gets the number of times the mouse button was pressed and released. (Inherited from MouseEventArgs)
ColumnIndex	Gets the zero-based column index of the cell.
Delta	Gets a signed count of the number of detents the mouse wheel has rotated, multiplied by the WHEEL_DELTA constant. A detent is one notch of the mouse wheel. (Inherited from MouseEventArgs)
Location	Gets the location of the mouse during the generating mouse event. (Inherited from MouseEventArgs)
RowIndex	Gets the zero-based row index of the cell.
X	Gets the x-coordinate of the mouse during the generating mouse event. (Inherited from MouseEventArgs)
Y	Gets the y-coordinate of the mouse during the generating mouse event. (Inherited from MouseEventArgs)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
