    foreach (ListViewItem item in lvPC.CheckedItems)
    {
        selectedTag = item.Tag.ToString();

        DialogResult result = MessageBox.Show
            ("Are you sure you want to remove this entry?",
            "Information", MessageBoxButtons.YesNo,
            MessageBoxIcon.Information);

        if (result == DialogResult.Yes)
        {
            // SQL query which will delete entry by using entry ID.
            string sql = "DELETE FROM PersonalData WHERE DataID = " + selectedTag;

            DeleteData(sql, selectedTag);

            DisplayFileContent(filePath);
        }
        else
        {
            if (lvPC.CheckedItems == CheckState.Checked)
                item = CheckState.Unchecked;
        }
    }
