如何在网格视图中对多个列进行排序 [英] how to sort multiple colum in grid view

问题描述

亲爱的所有人，请告诉我们如何使用示例

Dear all please tell to sort multiple column in grid view with example

推荐答案

如果您对表的任何列使用主键然后将始终根据该列进行排序.
它是主键的属性！

或者简单地，您可以对该列使用order by子句

If you use primary key to any column of the table then it will always be sorted according to that column all get sorted.
Its the property of primary key!

or simply you can use order by clause to that column

您必须保存要用来对网格视图记录排序进行排序的多列名称.保存按排序要求所需的用逗号(，)分隔的列名.

You have to save the multiple column name by which you want the sorting of the grid view record sorting. Save the column name separated by comma(,) as it is required as per sorting requirement.

private string GridViewSortExpression
    {
        get
        {
            return ViewState["SortExpression"] as string ?? string.Empty;
        }
        set
        {
            if (ViewState["SortExpression"] == null)
                ViewState["SortExpression"] = value;
            else if (ViewState["SortExpression"].ToString().Contains(value) == false)
                ViewState["SortExpression"] += "," + value;

        }
    }
