Ejemplos

En el ejemplo de código siguiente se muestra cómo controlar el evento CurrentCellDirtyStateChanged.The following code example demonstrates how to handle the CurrentCellDirtyStateChanged event. En este ejemplo, el controlador de eventos llama al método CommitEdit para generar el evento CellValueChanged y determinar el valor actual de un DataGridViewCheckBoxCell.In this example, the event handler calls the CommitEdit method to raise the CellValueChanged event and determine the current value of a DataGridViewCheckBoxCell. Este ejemplo de código forma parte de un ejemplo más grande proporcionado en [How para: Deshabilitar botones en una columna de botón en el control DataGridView Windows Forms @ no__t-0.This code example is part of a larger example provided in How to: Disable Buttons in a Button Column in the Windows Forms DataGridView Control.

// This event handler manually raises the CellValueChanged event
// by calling the CommitEdit method.
void dataGridView1_CurrentCellDirtyStateChanged(object sender,
    EventArgs e)
{
    if (dataGridView1.IsCurrentCellDirty)
    {
        dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}

// If a check box cell is clicked, this event handler disables  
// or enables the button in the same row as the clicked cell.
public void dataGridView1_CellValueChanged(object sender,
    DataGridViewCellEventArgs e)
{
    if (dataGridView1.Columns[e.ColumnIndex].Name == "CheckBoxes")
    {
        DataGridViewDisableButtonCell buttonCell =
            (DataGridViewDisableButtonCell)dataGridView1.
            Rows[e.RowIndex].Cells["Buttons"];

        DataGridViewCheckBoxCell checkCell =
            (DataGridViewCheckBoxCell)dataGridView1.
            Rows[e.RowIndex].Cells["CheckBoxes"];
        buttonCell.Enabled = !(Boolean)checkCell.Value;

        dataGridView1.Invalidate();
    }
}
' This event handler manually raises the CellValueChanged event
' by calling the CommitEdit method.
Sub dataGridView1_CurrentCellDirtyStateChanged( _
    ByVal sender As Object, ByVal e As EventArgs) _
    Handles dataGridView1.CurrentCellDirtyStateChanged

    If dataGridView1.IsCurrentCellDirty Then
        dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit)
    End If
End Sub

' If a check box cell is clicked, this event handler disables  
' or enables the button in the same row as the clicked cell.
Public Sub dataGridView1_CellValueChanged(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellValueChanged

    If dataGridView1.Columns(e.ColumnIndex).Name = "CheckBoxes" Then
        Dim buttonCell As DataGridViewDisableButtonCell = _
            CType(dataGridView1.Rows(e.RowIndex).Cells("Buttons"), _
            DataGridViewDisableButtonCell)

        Dim checkCell As DataGridViewCheckBoxCell = _
            CType(dataGridView1.Rows(e.RowIndex).Cells("CheckBoxes"), _
            DataGridViewCheckBoxCell)
        buttonCell.Enabled = Not CType(checkCell.Value, [Boolean])

        dataGridView1.Invalidate()
    End If
End Sub

Comentarios

Una celda se marca como modificada si su contenido ha cambiado pero el cambio no se ha guardado.A cell is marked as modified if its contents have changed but the change has not been saved.

Normalmente, este evento se produce cuando se ha editado una celda pero el cambio no se ha confirmado en la caché de datos o cuando se cancela una operación de edición.This event typically occurs when a cell has been edited but the change has not been committed to the data cache, or when an edit operation is canceled.
