如何在GridView内嵌GridView控件里的控件显示数据

sp_help 2009-04-10 02:56:51

//第一层GridView

<asp:GridView ID="GridView1"DataSourceID="ObjectDataSource1" onrowcommand="GridView1_RowCommand" onrowdatabound="GridView1_RowDataBound" Width="1502px">
<Columns>
<asp:TemplateField HeaderText="订单编号" ItemStyle-Width="45px" >
<ItemTemplate>
<asp:Label ID="lblSO" Text='<%# Eval("SO") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="出货日期" ItemStyle-Width="60px"
ItemStyle-Wrap="false">
<ItemTemplate >
<asp:Label ID="lbloutdate"
Text='<%# DataBinder.Eval(Container.DataItem,"outdate","{0:yy-M-d}")%> '
runat="server"></asp:Label>
</ItemTemplate>
<asp:TemplateField HeaderText="ITEM">
<ItemTemplate>

//第2层GridView <asp:GridView ID="GridView2" OnRowDataBound = "GridView2_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="ITEM" SortExpression="prd_no"
ItemStyle-Width="35px">
<ItemTemplate>
<asp:Label ID="lblOrderID" Text='<%# Eval("prd_no") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="数量" SortExpression="outdate">
<ItemTemplate >
<asp:Label ID="lblNUM" Text='' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>

</Columns>
</asp:GridView>

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

CS代码:

protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{

//我想第二层GridView2中的lblNUM显示我的数据如:200,这代码怎么写
//这语句行不通
// Label strNUM= (Label)e.Row.FindControl("lblNUM");
strNUM.text="200";
}

[Quote=引用 10 楼 sp_help 的回复:]
Sandy945和maggie3256的代码很好.

正确结果要的是
protected void gvChild_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
代码放这
Label strNUM= (Label)e.Row.FindControl("lblNUM");
strNUM.text="200";
}
}

再问
if (e.Row.RowType == DataControlRowType.DataRow) 能给说什么意思吗?

当前行的类型为数据行
DataControlRowType 是个枚举类型，你可以自己看下都有那些的

還可以直接創建DataSet兩個表的關聯，這個就不用這麼麻煩的邦定了

建议将第二个 GridView放在一个自定义控件中会更好操作些

<GridView1>
<item>
<myControl:GridView2 ID='xx' runat='server' ParentID='<%#Eval("Id")%>' />
</item>
</GridView1>

自定义控件myControl_GridView2:

在 Page_Load()上面声明控件属性：
protected int _parentId;
public int ParentID
{
get{return _parentId;}
set{_parentId=value; }
}
Page_Load()
{
//其父级 ID就是 _parentId （SELECT * FROM TB where ParentId=@ParentId,N'@ParentId _parentId'）
}

private void GridView2_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
{

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Label strNUM= (Label)e.Row.FindControl("lblNUM");
strNUM.text="200";

}
}
