目前我有一个附加到 GridView 的 DetailsView。当您从 GridView 中选择一个项目时,详细信息会显示在 DetailsView 中(duh)。现在,DetailsView 上有 3 个事件选项:编辑、删除和新建。我想添加第四个,格式。这将简单地运行一些查询,然后执行删除。这可能吗?如何?

另一种可能性是将此事件添加到 GridView 中(也许在编辑模式下?)

如果您按照建议将自己的按钮添加到 DetailsView,您可以在 DetailsView 上挂钩 ItemCommand 事件,并在 ItemCommand 方法中为每个 CommandName 添加任何逻辑

    void CustomerDetailView_ItemCommand(Object sender, DetailsViewCommandEventArgs e)
    {

        // Use the CommandName property to determine which button
        // was clicked. 
        if (e.CommandName == "Add")
        {

            // Add the current store to the contact list. 

            // Get the row that contains the store name. In this
            // example, the store name is in the second row (index 1)  
            // of the DetailsView control.
            DetailsViewRow row = CustomerDetailView.Rows[1];

            // Get the store's name from the appropriate cell.
            // In this example, the store name is in the second cell  
            // (index 1) of the row.
            String name = row.Cells[1].Text;

            // Create a ListItem object with the store's name.
            ListItem item = new ListItem(name);

            // Add the ListItem object to the ListBox, if the 
            // item doesn't already exist.
            if (!ContactListBox.Items.Contains(item))
            {
                ContactListBox.Items.Add(item);
            }

        }

    }
