DataGridViewDataErrorEventArgs.Exception Property

Gets the exception that represents the error.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public Exception Exception { get; }

Property Value

Type: System.Exception
An Exception that represents the error.

To handle the exception by more than one DataGridViewDataErrorEventHandler, throw the exception again at the end of a handler by setting the ThrowException property to true.

The following code example demonstrates checking the Exception property. This example is part of a larger example available in the DataGridViewComboBoxColumn class overview topic.

private void DataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs anError)
{

    MessageBox.Show("Error happened " + anError.Context.ToString());

    if (anError.Context == DataGridViewDataErrorContexts.Commit)
    {
        MessageBox.Show("Commit error");
    }
    if (anError.Context == DataGridViewDataErrorContexts.CurrentCellChange)
    {
        MessageBox.Show("Cell change");
    }
    if (anError.Context == DataGridViewDataErrorContexts.Parsing)
    {
        MessageBox.Show("parsing error");
    }
    if (anError.Context == DataGridViewDataErrorContexts.LeaveControl)
    {
        MessageBox.Show("leave control error");
    }

    if ((anError.Exception) is ConstraintException)
    {
        DataGridView view = (DataGridView)sender;
        view.Rows[anError.RowIndex].ErrorText = "an error";
        view.Rows[anError.RowIndex].Cells[anError.ColumnIndex].ErrorText = "an error";

        anError.ThrowException = false;
    }
}
