Question

I am trying to write a function as follows:

private void Func1(DataColumnChangeEventArgs e)
{
    ds.TableName.AddRow(
        e.Row[e.Column.ColumnName, DataRowVersion.Original].ToString(),
    e.Row[e.Column.ColumnName, DataRowVersion.Proposed].ToString());
}

and I am calling it as:

private void Func2()
{
    DataColumnChangeEventArgs e = new DataColumnChangeEventArgs(
        dataTable.Rows[index],
        dataTable.Columns["ColName"],
        newValue);

    e.ProposedValue = newValue;
    Func1(e);
}

However, e.Row[e.Column.ColumnName, DataRowVersion.Proposed].ToString() is throwing a VersionNotFoundException. Is there any way to achieve this?

Answer 1

I would say, your method should look like this:

ds.TableName.AddRow(e.Row[e.Column.ColumnName].ToString(), e.ProposedValue.ToString());

As there is no versions in that row in your row in args, but there is new and old values…
