我正在尝试使用转发器显示购物类别及其子类别和子子类别。数据是绑定的,但它没有被显示。任何人都可以帮助为什么?这是我的代码:
.aspx 文件
<asp:Repeater ID="CategoryRepeater" runat="server" OnItemDataBound="CategoryRepeater_OnItemDataBound">
<ItemTemplate>
<a href='Clothing.aspx?CategoryId=<%#Eval("CategoryId") %>'<%#Eval("CategoryName") %>></a><br />
<asp:Repeater ID="SubCategoryRepeater" runat="server" OnItemDataBound="SubCategoryRepeater_OnItemDataBound">
<ItemTemplate>
<a href='Clothing.aspx?CategoryId=<%#Eval("CategoryId") %>&SubCategoryId=<%#Eval("SubCategoryId") %>'<%#Eval("SubCategoryName") %>></a><br />
<asp:Repeater ID="SubSubCategoryRepeater" runat="server">
<ItemTemplate>
<a href='Clothing.aspx?CategoryId=<%#Eval("CategoryId") %>&SubCategoryId=<%#Eval("SubCategoryId") %>&SubSubCategoryId=<%#Eval("SubSubCategoryId") %>'<%#Eval("SubSubCategoryName") %>></a><br />
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
C#代码:
protected void CategoryRepeater_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item)||(e.Item.ItemType == ListItemType.AlternatingItem))
{
DataRowView dataItem = e.Item.DataItem as DataRowView;
int categoryId = Convert.ToInt32(dataItem["CategoryId"]);
Repeater rp = (Repeater)e.Item.FindControl("SubCategoryRepeater");
ds = us.SelectSubCategories(categoryId);
rp.DataSource = ds;
rp.DataBind();
}
}
protected void SubCategoryRepeater_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item)||(e.Item.ItemType == ListItemType.AlternatingItem))
{
DataRowView dataItem = e.Item.DataItem as DataRowView;
int SubCategoryId = Convert.ToInt32(dataItem["SubCategoryId"]);
Repeater rp1 = (Repeater)e.Item.FindControl("SubSubCategoryRepeater");
ds1 = us.SelectSubSubCategories(SubCategoryId);
rp1.DataSource = ds1;
rp1.DataBind();
}
}
