如何获取自定义gridview中第二个标题行中的事件

我需要向我的 ASP.NET GridView 添加一个辅助（标题）行（它已经自定义，因此我可以访问事件生命周期的任何部分）。

这是我想要与某些列对齐的附加数据。

它应该看起来像这样，

Period    |  May  |  June | July | Aug      -- Header
Basevalue | 3000  | 1500  | 1200 | 4000     -- EXTERNAL DATA
---------------------------------------
Item 1    |  100  |  200  |  300 |  400    
Item 2    |  100  |  200  |  300 |  400

我设法使用下面的代码添加一行，但我无法创建任何类型的自定义事件，在其中我可以获得访问权限并将自定义数据写入该单元格。我尝试了以下操作，但在我能找到的任何事件（如 OnRowCreated 或PrepareControlHierarchy）期间，要么为时已晚（在数据绑定之后），要么内表未初始化。

int rowIndex = 0;

GridViewRow secondHeaderRow = new GridViewRow(rowIndex, -1, DataControlRowType.Header, DataControlRowState.Normal);
secondHeaderRow.TableSection = TableRowSection.TableHeader;

foreach (DataControlField col in this.Columns)
            {
                TableHeaderCell cell = new TableHeaderCell();
                cell.DataBinding += new EventHandler(OnHeaderCellDatabinding);
                secondHeaderRow.Cells.Add(cell);
            }

 InnerTable.Rows.AddAt(rowIndex, secondHeaderRow);

如何连接 GridView 生命周期以在标题行中写入？

原文

I need to add a secondary (header) row to my ASP.NET GridView (which is already customized so I can access any part of the event lifecycle).

It's additional data that I want aligned with some of the columns.

It should look like this

Period    |  May  |  June | July | Aug      -- Header
Basevalue | 3000  | 1500  | 1200 | 4000     -- EXTERNAL DATA
---------------------------------------
Item 1    |  100  |  200  |  300 |  400    
Item 2    |  100  |  200  |  300 |  400

I managed to add a row with below code, but I am unable to create any kind of custom event where I could gain access and write my custom data into that cell. I tried the following, but during any event I could find (like OnRowCreated or PrepareControlHierarchy), it's either too late (after databinding) or the inner table is not initalized.

int rowIndex = 0;

GridViewRow secondHeaderRow = new GridViewRow(rowIndex, -1, DataControlRowType.Header, DataControlRowState.Normal);
secondHeaderRow.TableSection = TableRowSection.TableHeader;

foreach (DataControlField col in this.Columns)
            {
                TableHeaderCell cell = new TableHeaderCell();
                cell.DataBinding += new EventHandler(OnHeaderCellDatabinding);
                secondHeaderRow.Cells.Add(cell);
            }

 InnerTable.Rows.AddAt(rowIndex, secondHeaderRow);

How can I hook up to the GridView lifecycle to write in the header row?
