这是我的文本框和按钮

< asp：TextBox ID =   txtSearch runat =   server >  < /   asp：TextBox  >  
< asp：按钮ID =   btnSearch runat =   server Text =  搜索 /> 

这就是我想要做的。 
 DATALIST：

文本框搜索：Samsung Galaxy S4 
当按钮点击datalis显示：
 
 Datalist ：
产品编号：2424（<  - 示例）
产品名称：Samsung Galaxy S4 
描述：Blah blah blah .... 
价格：$ 300（< ;-例子）

将数据绑定到datalist时，在viewstate中复制数据，然后当用户搜索数据时，从viewstate获取并显示。

<asp:DataList ID="DataList1" runat="server" DataKeyField="ProductID" 
        DataSourceID="SqlDataSource1" onitemdatabound="use" BackColor="White" 
        EmptyDataText="Please Select Category."
           BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" 
           GridLines="Horizontal" RepeatColumns="3" RepeatDirection="Horizontal" 
        Height="534px" Width="726px" style="text-align: center; color: #000000;" OnItemCommand="DataList1_ItemCommand">
        <AlternatingItemStyle BackColor="White" />
        <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
        <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#F7F7F7" />
        <ItemStyle BackColor="White" ForeColor="#4A3C8C" />
         <ItemTemplate>
            <asp:ImageButton ID="btnFileImg" runat="server" Height="150px" Width="100px" ImageUrl='<%# Eval("filename") %>'  PostBackUrl='<%# Eval("ProductID", "ProductDetails.aspx?ProductID={0}") %>' />
            <asp:Label ID="ImageUrlLabel" runat="server" Text='<%# Eval("filename") %>' Visible="False"></asp:Label><br />
    <br />
            <a href='ProductDetails.aspx?productID=<%# Eval("ProductID") %>' style="font-size: 15px; color: black">
            <asp:Label ID="NameLabel" runat="server" Text='<%# Eval("productName") %>'/><br />
            </a>
            Price: 
            <asp:Label ID="PriceLabel" runat="server" Text='<%# Eval("price") %>' />

        </ItemTemplate>
        <SelectedItemStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
    </asp:DataList>

This is my Textbox and Button

<asp:TextBox ID="txtSearch" runat="server"></asp:TextBox>
    <asp:Button ID="btnSearch" runat="server" Text="Search" />

This is what I want to do.
DATALIST:

LIST OF PRODUCTS

Textbox search: Samsung Galaxy S4
When button click datalis shows:

Datalist:
Product ID: 2424(<-- example)
Product Name: Samsung Galaxy S4
Description: Blah blah blah....
Price: $300(<- example)
Stock: 5(<-- example)


Thanks in advance

Hi,
When you bind the data to datalist, copy the data in viewstate and then when user searches the data, take from the viewstate and display.
