问题描述
我使用嵌套GridView的,其中在的GridView 的有子GridView的每一行。 我使用的的RowDataBound 赛事的父GridView控件的,有约束力的子的GridView 的。 我的问题是,如何让家长GridView的儿童GridView的关键的RowDataBound 事件。
I am using Nested GridViews where each row in the gridview has child gridView. I am using RowDataBound Event of Parent GridView, to Binding Child GridView. My Problem is that, how to get Parent GridView's Key on Child gridViews RowDataBound Event.
下面的例子code:
<asp:GridView ID="gvParent" DataKeyNames="ID" runat="server" PageSize="1" AllowPaging="true" PagerSettings-Mode="NextPrevious" AutoGenerateColumns="False" SkinID="GVCenter" onrowdatabound="gvParent_RowDataBound">
<Columns>
<asp:BoundField DataField="Name" />
<asp:TemplateField>
<ItemTemplate>
<asp:GridView ID="gvChild" DataKeyNames="ID" runat="server" AutoGenerateColumns="false" ShowHeader="false" OnRowDataBound="gvChild_RowDataBound">
<Columns>
<asp:BoundField DataField="Name" />
</Columns>
</asp:GridView>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
下面是code背后:
protected void gvParent_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView gvChild= (GridView)e.Row.FindControl("gvChild");
gvChild.DataSource = getChildObj();
gvChild.DataBind();
}
}
protected void gvChild_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// Here I need to get the parent gridview Row Key
}
}
希望以上code解释了所有的场景。
Hope the above code explains all the scenario.

推荐答案
试试这个
<asp:GridView ID="gvParent" DataKeyNames="ID" runat="server" PageSize="10" AllowPaging="true"
PagerSettings-Mode="NextPrevious" AutoGenerateColumns="False" OnRowDataBound="gvParent_RowDataBound">
<Columns>
<asp:BoundField DataField="Name" />
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="HdnID" runat="server" Value='<%# Eval("ID") %>' />
<asp:GridView ID="gvChild" DataKeyNames="ID" runat="server" AutoGenerateColumns="false"
ShowHeader="false" OnRowDataBound="gvChild_RowDataBound">
<Columns>
<asp:BoundField DataField="Name" />
</Columns>
</asp:GridView>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
$ C $后面
Code behind
protected void gvParent_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView gvChild = (GridView)e.Row.FindControl("gvChild");
gvChild.DataSource = GetData();
gvChild.DataBind();
}
}
protected void gvChild_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string ID = ((HiddenField)e.Row.Parent.Parent.Parent.FindControl("HdnID")).Value;
}
}
