using System.Drawing;
protected void treeList_HtmlRowPrepared(object sender, TreeListHtmlRowEventArgs e) {
if(Object.Equals(e.GetValue("Location"), "Monterey"))
e.Row.BackColor = Color.FromArgb(211, 235, 183);
}
protected void treeList_HtmlDataCellPrepared(object sender, TreeListHtmlDataCellEventArgs e) {
if(e.Column.Name == "budget") {
decimal value = (decimal)e.CellValue;
e.Cell.BackColor = GetBudgetColor(value);
if(value > 1000000M)
e.Cell.Font.Bold = true;
}
}
