Question

I am trying to learn the basics of making databases in Visual C#, and I am building a basic application. In the application there is a delete button that will delete the record that is currently shown in the textboxes. The code I have at the moment is this:

private void btnDelete_Click(object sender, EventArgs e)
{
    currentRow.Delete();
    dAdapter.Update(dataset, "Contacts");
    clearTextBoxes();
}

currentRow is the DataRow I want to delete and that which is shown in the textboxes. dataset is the Dataset. dAdapter is the DataAdapter, and “Contacts” is the table name or w/e. However this is generating an error sometimes. What’s wrong here? Thanks!

Answer 1

Have you set the dAdapter.DeleteCommand property? Based on the error message, it sounds like this property might not be set or may be invalid.
