Question

I am new to c# and Database linking that’s why not able to get this by searching old posts of stackoverflow

Code like

private void bookDetails()
    {
        string connectionPath = @"Data Source=Data\libraryData.dat;Version=3;New=False;Compress=True";

        using (SQLiteConnection connection = new SQLiteConnection(connectionPath))
        {
            SQLiteCommand command = connection.CreateCommand();
            connection.Open();
            string query = "SELECT bookno as 'Book No.', bookCode as 'ISBN No.', title as 'Title', author as 'Author', publisher as 'Publishers', edition as 'Edition', storagehint as 'Storage Hint', description as 'Description' FROM booksDetails";
            command.CommandText = query;
            command.ExecuteNonQuery();

            SQLiteDataAdapter da = new SQLiteDataAdapter(command);
            DataSet ds = new DataSet();
            da.Fill(ds, "booksDetails");
            int c = ds.Tables["booksDetails"].Rows.Count;
            dataGridView1.DataSource = ds.Tables["booksDetails"];
            dataGridView1.Sort(dataGridView1.Columns["ISBN No."], ListSortDirection.Ascending);
            dataGridView1.ReadOnly = true;
            connection.Close();
            this.Totals.Text = "Total No. of Books Found : "+ Convert.ToString(c);
        }
    }

i used like above for getting some library book details, now i want highlight a particular cell or change its color by the value of no. of book or any other..

sample code preferred

thanks in advance…

Answer 1

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        Color c = Color.Black;
        if (e.ColumnIndex == 6)
        {
            if (isLate(Convert.ToString(e.Value)))
                c = Color.Red;
        }
        e.CellStyle.ForeColor = c; // or e.CellStyle.BackColor= c; whatever you can do like this

    }

and code for event is

this.dataGridView1.CellFormatting += new System.Windows.Forms.DataGridViewCellFormattingEventHandler(this.dataGridView1_CellFormatting);

this will be auto generated in yourform.designer.cs or else you add it manually
