DataGridView.CellContentClick Event

Occurs when the content within a cell is clicked.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
public event DataGridViewCellEventHandler CellContentClick

This event occurs when the cell content is clicked. It also occurs when the user presses and releases the SPACEBAR while a button cell or check box cell has focus, and will occur twice for these cell types if the cell content is clicked while pressing the SPACEBAR.

Use this event to detect button clicks for a DataGridViewButtonCell or link clicks for a DataGridViewLinkCell.

For clicks in a DataGridViewCheckBoxCell, this event occurs before the check box changes value, so if you do not want to calculate the expected value based on the current value, you will typically handle the DataGridView.CellValueChanged event instead. Because that event occurs only when the user-specified value is committed, which typically occurs when focus leaves the cell, you must also handle the DataGridView.CurrentCellDirtyStateChanged event. In that handler, if the current cell is a check box cell, call the DataGridView.CommitEdit method and pass in the Commit value.

For more information about handling events, see Consuming Events.

The following code example provides a handler for this event that determines whether the clicked cell is a link cell or a button cell and performs the corresponding action as a result. This example is part of a larger example available in the DataGridViewComboBoxColumn class overview topic.

private void DataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{

    if (IsANonHeaderLinkCell(e))
    {
        MoveToLinked(e);
    }
    else if (IsANonHeaderButtonCell(e))
    {
        PopulateSales(e);
    }
}

private void MoveToLinked(DataGridViewCellEventArgs e)
{
    string employeeId;
    object value = DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;
    if (value is DBNull) { return; }

    employeeId = value.ToString();
    DataGridViewCell boss = RetrieveSuperiorsLastNameCell(employeeId);
    if (boss != null)
    {
        DataGridView1.CurrentCell = boss;
    }
}

private bool IsANonHeaderLinkCell(DataGridViewCellEventArgs cellEvent)
{
    if (DataGridView1.Columns[cellEvent.ColumnIndex] is
        DataGridViewLinkColumn &&
        cellEvent.RowIndex != -1)
    { return true; }
    else { return false; }
}

private bool IsANonHeaderButtonCell(DataGridViewCellEventArgs cellEvent)
{
    if (DataGridView1.Columns[cellEvent.ColumnIndex] is
        DataGridViewButtonColumn &&
        cellEvent.RowIndex != -1)
    { return true; }
    else { return (false); }
}

private DataGridViewCell RetrieveSuperiorsLastNameCell(string employeeId)
{

    foreach (DataGridViewRow row in DataGridView1.Rows)
    {
        if (row.IsNewRow) { return null; }
        if (row.Cells[ColumnName.EmployeeId.ToString()].Value.ToString().Equals(employeeId))
        {
            return row.Cells[ColumnName.LastName.ToString()];
        }
    }
    return null;
}
