Bulid a serach feature .

Hello,
I'm trying to build a search feature where a user enters a text value and the page returns records where the string appears in a specific field.

Can help me to find tutorials to explain the steps of building search feature by using LIKE/ SQL.

You can do that using a gridview.

Here is an example of search. This actually works because I use it:

       <form id="form1" runat="server">
       <div style="text-align:center">
        <asp:Label ID="enterNamebutton" Text="<b>Enter Name</b>" runat="server" />
        <asp:TextBox ID="txtSearch" runat="server" style="height:23px"></asp:TextBox>
        <asp:Button ID="btnSearch" runat="server" TabIndex="1" height="27px" Text="GO" OnClick="btnSearch_Click" class="btn" />
        <asp:Button ID="btnClear" OnClick="ClearFilter" height="27px" Text="Reset" runat="server" class="btn" />
        </div>
        <br /><br />
         <div style="text-align:left">
         <div style="text-align:center">SEARCH By Last Name, First Name (e.g.; Doe, John) and click the <div style="color:#69e">Go</div> button
            Click the <div style="color:#69e;white-space:nowrap">Reset</div> button to SEARCH again<br /><br />
         <asp:GridView ID="GridView1" BorderWidth="0" runat="server" AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True" PageSize="15" DataSourceID="APOMembers" EmptyDataText="No data found" Width="564px">

       </div>

How are you looking for available hotels?

Do you have a database of a list of hotels?

I have a database for the hotels and rooms available.
and I\m using that way>

string SearchType = Request.Params["id_input"];

query.CommandText = " SELECT Name,Type FROM Hotels WHERE (Name LIKE '" + SearchType + "' + '%' )";

Try these and let me know. If you have a code different from this, show where you are having issues.

Please change whatever needs changing.

I am not c# guy but I think the codeFile looks good.

Sorry change this line:

this.txtSearch.Text = string.Empty;

To

this.SearchType.Text = string.Empty;

I'm looking to create search for my hotel booing system ?
And the result get from the database, and you can search by CITY,COUNTRY, NUMBER OF ROOM, NUMBER OF NIGHT. like www.hotel.com

Regards

sammySeltzer🇺🇸

Well if you want to use all those as your search param, then use this code:

<asp:TextBox id="txtSearch" runat="server" />


	strSQLQuery = "SELECT  Name,Type FROM Hotels " _
	& "FROM Hotels" _
	& "WHERE city LIKE '%" & Replace(strSearch, "'", "''") & "%' " _
	& "OR country LIKE '%" & Replace(strSearch, "'", "''") & "%' " _
	& "OR [NUMBER OF ROOM] LIKE '%" & Replace(strSearch, "'", "''") & "%' " _				& "OR [NUMBER OF NIGHT] LIKE '%" & Replace(strSearch, "'", "''") & "%' " _
	& "ORDER BY city;"
