c#datagridview删除最后一个条目行

Question

I have problem with removing last row.

Here is code

 private void ponistiPrethodni_Click(object sender, EventArgs e)
    {

        int lastEntry = glProstor.Rows.Count - 1;
        System.Diagnostics.Debug.WriteLine(lastEntry);
        glProstor.Rows.RemoveAt(lastEntry);

    }

I get exeption with

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

Additional information: Uncommitted new row cannot be deleted.
