asp.net嵌套的gridview模板控件
[英]asp.net nested gridview template controls
问题描述
I have a gridview inside a gridview's "ItemTemplate". 
我在gridview的“ ItemTemplate”中有一个gridview。 The outside gridview, (gvPOs) , has a "select" option. 外部gridview（gvPOs）具有“选择”选项。 Since my sql data source is handled through code behind, not sqldatasource through design mode, there's no "enable select" , "enable delete", etc. So I added select under "edit columns" as a CommandField. 由于我的sql数据源是通过后面的代码处理的，而不是通过设计模式通过sqldatasource处理的，因此没有“启用选择”，“启用删除”等。因此，我在“编辑列”下添加了select作为CommandField。 Usually, when a gridview is by itself , and I make a formview using the table data to display that information, I can just fill in the where clause to display where ID is from gvPOs.SelectedValue control and it would show that specific line. 通常，当gridview本身是一个，而我使用表数据显示一个formview来显示该信息时，我只需填写where子句以显示ID来自gvPOs.SelectedValue控件的位置，它将显示该特定行。 But in this case, since there's a nested gridview, for some reason when I do that, "select" doesn't do anything. 但是在这种情况下，由于存在嵌套的gridview，出于某种原因，当我这样做时，“选择”不会执行任何操作。
Output http://i57.tinypic.com/14ue0kg.png 输出http://i57.tinypic.com/14ue0kg.png
I'm trying to get the select on the far right column of the outside gridview to open up my formview that corresponds to the PO_ID. 我正在尝试在外部gridview的最右列上进行选择，以打开与PO_ID相对应的formview。
The left side is just to show what else it's doing. 左侧只是为了显示它在做什么。 When the expand button is clicked on the left, the 2nd gridview pops up with the records that have that PO_ID. 单击左侧的扩展按钮时，第二个网格视图会弹出，其中包含具有该PO_ID的记录。 My overall goal is to be able to add, delete, and edit records from both tables. 我的总体目标是能够从两个表中添加，删除和编辑记录。

I am not able to understand your problem 100%. 我无法100％理解您的问题。 if you want to use nested GridView, bind child GridView in Row_DataBound event of parent GridView. 如果要使用嵌套的GridView，请在父GridView的Row_DataBound事件中绑定子GridView。 Make sure you bind parent gridview inside if(!Page.IsPostBack) condition so once you hit select button it won't bind parent GridView. 确保在if（！Page.IsPostBack）条件内绑定父Gridview，因此一旦按下选择按钮，它将不会绑定父GridView。
