设置某一列为只读
this.ultraGrid1.DisplayLayout.Bands[0].Columns[0].CellActivation = Activation.ActivateOnly;

选择后的缺省前景和背景色
this.ultraGrid1.DisplayLayout.DefaultSelectedBackColor = Color.Azure;
this.ultraGrid1.DisplayLayout.DefaultSelectedForeColor = Color.YellowGreen;

使用dataset绑定。
检索数据，建立table之间的关系。ultraGrid自动建立层次式展示方式。
DataSet data = new DataSet();
SqlDataAdapter da = new SqlDataAdapter("select * from customers", cnnstring);
da.Fill(data, "Customers");
da = new SqlDataAdapter("select * from pdctorders", cnnstring);
da.Fill(data, "PdctOrders");
DataRelation mydr = new DataRelation("Customers_PdctOrders", data.Tables["Customers"].Columns["CustID"], data.Tables["pdctorders"].Columns["CustID"], false);
data.Relations.Add(mydr);

da = new SqlDataAdapter("select * from SaleContracts", cnnstring);
da.Fill(data, "SaleContracts");
DataRelation mydr2 = new DataRelation("Customers_SaleContracts", data.Tables["Customers"].Columns["CustID"], data.Tables["SaleContracts"].Columns["CustID"],

false);
data.Relations.Add(mydr2);

this.ultraGrid1.DataSource = data;
1）系统自动根据源数据的类型选择合适的控件展示，如日历控件、单选框等；
2）缺省都是左对齐的；
3）所有数据原样显示，没有格式化的。

如何根据数据类型自动设置列，如格式、对齐等？
            foreach (UltraGridBand ugb in this.ultraGrid1.DisplayLayout.Bands)
            {
                foreach (UltraGridColumn ugc in ugb.Columns)
                {
                    if (ugc.DataType == Type.GetType("System.Int8") ||
                        ugc.DataType == Type.GetType("System.Int16") ||
                        ugc.DataType == Type.GetType("System.Int32") ||
                        ugc.DataType == Type.GetType("System.Int64"))
                    {
                        ugc.Format = "#,#";
                        ugc.CellAppearance.TextHAlign = HAlign.Right;
                    }
                    else if (ugc.DataType == Type.GetType("System.Single") ||
                        ugc.DataType == Type.GetType("System.Double"))
                    {
                        ugc.Format = "#,0.00";
                        ugc.CellAppearance.TextHAlign = HAlign.Right;
                    }
                    else if (ugc.DataType == Type.GetType("System.DateTime"))
                    {
                        ugc.Format = "yyyy/MM/dd";
                        ugc.MaskInput = "yyyy/mm/dd";
                    }
                }
            }
