如何使用C＃在ASP.NET上添加搜索栏

问题描述：

大家好，我有数据库设置，

1条码有很多商品代码。

i希望创建一个用户输入条形码的搜索栏，并以复选框/子弹形式显示该条形码下的所有项目代码，这样我就可以选择我想要的项目代码以进一步发挥功能。

就像我说的查询和东西我都很好。现在我是如何喜欢文本框，它是执行onclick搜索按钮的输入。

用户标签吗？按钮？提交？他们需要处于某种形式吗？

感谢您的帮助。我看到太多的例子。

我尝试过的事情：

Hi guys, i got the database setup,

1 barcode has many item code.

i want to create a search bar that user enter the barcode and will display all the item code under that barcode in a checkbox/bullet form so i can select which item code i want for futher function.

like i said the query and stuff i am all good. now is how do i like the textbox that is the input to the button that perform onclick for search.

do i user label? button? submit? do they need to be in a form?

Thanks for helping. i am seeing too many example.

What I have tried:

 <asp:Label ID="barSearch" runat="server" Text="">Enter Barcode: </asp:Label>

<asp:Button runat="server" ID="btnSearchBar" Style="background-color: #c9302c;" CssClass="btn btn-danger" Text="Search" OnClientClick="javascipt: return confirm('are you sure want to search ?');"CommandArgument='txtSearchString>' CommandName="search" OnClick="btnSearchBar_Click" />        

    </div>

答

试试这样

ASPX

try like this

ASPX

<div>
           <span>Enter Barcode: </span>
           <asp:TextBox runat="server" ID="txtSearch" />
           <asp:Button runat="server" ID="btnSearchBar" Style="background-color: #c9302c;" CssClass="btn btn-danger" Text="Search" OnClientClick="javascipt: return confirm('are you sure want to search ?');" OnClick="btnSearchBar_Click" />
           <asp:BulletedList ID="bltLstSearchItems" runat="server">
           </asp:BulletedList>

       </div>

代码背后

Code Behind

protected void btnSearchBar_Click(object sender, EventArgs e)
        {
            string value = txtSearch.Text.Trim();
            // Your Ado.Net code to get data from DB
            string[] itemsGotFromDB = { "aaaa", "bbbb", "etc" };
            bltLstSearchItems.DataSource = itemsGotFromDB;
            bltLstSearchItems.DataBind();
        }
