当我在同一页面中选择不同的项目时，如何更改页面URL [英] How to change page url when i select different item in the same page
问题描述
我有一个页面，其中包含根据类别显示的产品列表...
当我在左侧菜单中选择类别时，我已根据所选类别显示产品但在网址中catagiry id尚未更改。我需要更改该页面网址中的类别ID ...
设计代码如下所示....
Hi,
I have a page which contains list of Products displayed based on catagories...
When i select catagory in left side menu i have displayed the products based on that selected catagory but in the url the catagiry id has not been changed.i need to change the catagory id in the url of that page...
The design code looks like this....
<asp:DataList runat="server" OnItemDataBound="dlProducts_ItemDataBound" ID="dlProducts"
RepeatColumns="4" RepeatDirection="Horizontal">
<ItemTemplate>
<li>
<asp:HiddenField runat="server" ID="hdnItemID" Value=''<%# DataBinder.Eval(Container.DataItem, "ItemID")%>'' />
<asp:HiddenField ID="hdndCatlog" runat="server" />
<div class="productsimg" önclick="SelectProduct(<%# DataBinder.Eval(Container.DataItem, "ItemID")%>,this);">
<img src=''<%#((string[]) DataBinder.Eval(Container.DataItem, "ThumbnailPaths"))[0]%>'' />
</div>
<div class="productscost">
<div class="productsname">
<h6>
<%# DataBinder.Eval(Container.DataItem, "StockNo")%></h6>
<p>
$<asp:Label runat="server" ID="lblItemPrice"></asp:Label></p>
</div>
<a href=''java<!-- no -->script:AddItemtoCart(<%# DataBinder.Eval(Container.DataItem, "ItemID")%>)''>
<div class="addtocart">
Add to CART
</div>
</a>
</div>
</li>
</ItemTemplate>
</asp:DataList>
当我点击此中的cataory名称我展示了产品（项目）..代码看起来像这样..
When i click cataory name in this i have displayed products(items) ..code look like this..
protected void dlCategories_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName == "SELECT")
{
CtlId = int.Parse(e.CommandArgument.ToString());
Session["CtlId"] = CtlId;
BindItems(CtlId);
}
}
这样的网址.....
http：// localhost：58698 / Products / 37 [ ^ ]
当我点击另一个类别时，catagory id在上面的网址中没有变化..
请帮我解决这个问题..
