我使用此代碼但給出的錯誤對象引用未設置爲對象的實例。如何根據列值更改行顏色
using (SqlConnection sqlConn = new SqlConnection("Data Source=OMKAR-PC;Initial Catalog=omkar;Persist Security Info=True;User ID=sa;Password=omkar;Pooling=False"))
{
sqlConn.Open();
using (SqlDataAdapter a = new SqlDataAdapter("SELECT * FROM customer ", sqlConn))
{
DataTable t = new DataTable();
a.Fill(t);
dataGridView1.DataSource = t;
this.dataGridView1.CellFormatting +=
new DataGridViewCellFormattingEventHandler(dataGridView1_CellFormatting);
foreach (DataGridViewRow row in dataGridView1.Rows)
{
try
{
string CNumColour = dataGridView1.CurrentRow.Cells[0].FormattedValue.ToString();
if (CNumColour != null)
{
foreach (DataGridViewCell cells in row.Cells)
{
if (CNumColour == "yes")
{
cells.Style.ForeColor = Color.Pink;
}
else if (CNumColour == "no")
{
cells.Style.ForeColor = Color.Red;
}
}
}
}
catch (System.Exception ex)
{
}
}
sqlConn.Close();
}
哪條線給出錯誤? – Aditi 2013-04-30 05:40:36
