DataGridView.NotifyCurrentCellDirty(Boolean) Method

Definition

Notifies the DataGridView that the current cell has uncommitted changes.

C#
public virtual void NotifyCurrentCellDirty(bool dirty);

Parameters

dirty
Boolean

true to indicate the cell has uncommitted changes; otherwise, false.

Examples

The following code example illustrates the use of this method in a custom cell scenario. In the example, an IDataGridViewEditingControl implementation derived from the DateTimePicker class overrides the OnValueChanged method and uses the NotifyCurrentCellDirty method to indicate a change to the DataGridView control.

This example is part of a larger example shown in How to: Host Controls in Windows Forms DataGridView Cells.

C#
protected override void OnValueChanged(EventArgs eventargs)
{
    // Notify the DataGridView that the contents of the cell
    // have changed.
    valueChanged = true;
    this.EditingControlDataGridView.NotifyCurrentCellDirty(true);
    base.OnValueChanged(eventargs);
}

Remarks

This method can be used to allow custom cell types to notify the DataGridView when they have uncommitted changes.
