如果不和数据库连接的话,那么用xml,然后用DataSet绑定!要保存的时候用
StreamWriter myStreamWriter = new StreamWriter(xmlFilename);
DataSet1.WriteXml(myStreamWriter);
StreamWriter myStreamWriter = new StreamWriter(xmlFilename);
DataSet1.WriteXml(myStreamWriter);
// Step 1. Derive a custom column style from DataGridTextBoxColumn
// a) add a ComboBox member
// b) track when the combobox has focus in Enter and Leave events
// c) override Edit to allow the ComboBox to replace the TextBox
// d) override Commit to save the changed data
// Step 2 - Use the combo column style
// Add 1 col with combo style
DataGridComboBoxColumn ComboTextCol = new DataGridComboBoxColumn();
ComboTextCol.MappingName = "custCity";
ComboTextCol.HeaderText = "Customer Address";
ComboTextCol.Width = 100;
ts1.GridColumnStyles.Add(ComboTextCol);
// Step 3 - Additional setup for Combo style
// a) make the row height a little larger to handle minimum combo height
ts1.PreferredRowHeight = ComboTextCol.ColumnComboBox.Height + 3;
// b) Populate the combobox somehow. It is a normal combobox, so whatever...
ComboTextCol.ColumnComboBox.Items.Clear();
ComboTextCol.ColumnComboBox.Items.Add("Chicago");
ComboTextCol.ColumnComboBox.Items.Add("Corvallis");
ComboTextCol.ColumnComboBox.Items.Add("Denver");
ComboTextCol.ColumnComboBox.Items.Add("Great Falls");
ComboTextCol.ColumnComboBox.Items.Add("Kansas City");
ComboTextCol.ColumnComboBox.Items.Add("Los Angeles");
ComboTextCol.ColumnComboBox.Items.Add("Raleigh");
ComboTextCol.ColumnComboBox.Items.Add("Washington");
// c) set the dropdown style of the combo...
ComboTextCol.ColumnComboBox.DropDownStyle = ComboBoxStyle.DropDownList;
