To achieve custom sorting in a DataGridView, you can implement the SortCompare event of the DataGridView. This event is triggered when two cells in the DataGridView need to be compared and allows you to customize the comparison method within the event.<\/p>\n
Below is an example code demonstrating how to implement custom sorting in a DataGridView.<\/p>\n
private<\/span> void<\/span> dataGridView1_SortCompare<\/span>(object<\/span> sender, DataGridViewSortCompareEventArgs e<\/span>)<\/span>\r\n{\r\n \/\/ \u6307\u5b9a\u9700\u8981\u81ea\u5b9a\u4e49\u6392\u5e8f\u7684\u5217\u7684\u7d22\u5f15\uff08\u6b64\u5904\u5047\u8bbe\u9700\u8981\u5bf9\u7b2c\u4e00\u5217\u8fdb\u884c\u81ea\u5b9a\u4e49\u6392\u5e8f\uff09<\/span>\r\n if<\/span> (e.Column.Index == 0<\/span>)\r\n {\r\n \/\/ \u81ea\u5b9a\u4e49\u6bd4\u8f83\u903b\u8f91\uff0c\u6bd4\u5982\u5c06\u5355\u5143\u683c\u4e2d\u7684\u503c\u8f6c\u6362\u4e3a\u6574\u6570\u518d\u8fdb\u884c\u6bd4\u8f83<\/span>\r\n int<\/span> value1 = Convert.ToInt32(e.CellValue1);\r\n int<\/span> value2 = Convert.ToInt32(e.CellValue2);\r\n\r\n \/\/ \u8bbe\u7f6e\u6bd4\u8f83\u7ed3\u679c\uff0c1\u8868\u793avalue1\u5927\u4e8evalue2\uff0c-1\u8868\u793avalue1\u5c0f\u4e8evalue2\uff0c0\u8868\u793a\u76f8\u7b49<\/span>\r\n e.SortResult = value1.CompareTo(value2);\r\n\r\n \/\/ \u6807\u8bb0\u6bd4\u8f83\u5df2\u7ecf\u5904\u7406\uff0c\u4e0d\u518d\u4f7f\u7528\u9ed8\u8ba4\u6392\u5e8f<\/span>\r\n e.Handled = true<\/span>;\r\n }\r\n}\r\n<\/code><\/pre>\nAdd an event handler to the SortCompare event of the DataGridView when the form is loaded.<\/p>\n
private<\/span> void<\/span> Form1_Load<\/span>(object<\/span> sender, EventArgs e<\/span>)<\/span>\r\n{\r\n dataGridView1.SortCompare += dataGridView1_SortCompare;\r\n}\r\n<\/code><\/pre>\nThe code above demonstrates custom sorting of the first column. You can adjust the column index and comparison logic according to your needs. By implementing the SortCompare event, you can achieve custom sorting in DataGridView.<\/p>\n
