System.ArgumentException: DataGridViewComboBoxCell value is not valid

Question

dataGridView.Rows.Add(
    metaData.Offset.ToString("X2"),
    metaData.Length,
    metaData.Format,        // This parameter goes to a ComboBox cell which throws an
    metaData.Description,   //     exception above                       
    null,
    null);

What is the valid way to programmatically assign data to DataGridViewComboBoxCell?

Answer 1

To Solve this problem, just add “DataError” for DataGridView. That’s all, steps: Double click the datagridview and select the “dataerror” event from the event list.

The DataError event enables you to handle exceptions thrown in code that is called by the control during data processing operations.

thats it :)

Answer 2

To Solve this problem, add event of "DataError" for DataGridView and then

just write this: e.Cancel = true;

e.g:

private void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e)
{
    e.Cancel = true;
}
