    text
    <p>I'm trying to create an ASP.NET webpage to output a textbox, then user will enter the key in this textbox and I use that key to put into WHERE condition in SQL code to output data that matches the key. For example, user enters ArtistID in the textbox and I need to print the table SPEEDOFSALEREPORT using </p> <blockquote> <p>SELECT * FROM SPEEDOFSALEREPORT WHERE ArtistID = "the key that user just enter"</p> </blockquote> <p>but I don't know how. My code below creates a text box and print all rows in the table. Please give me a hint. I tried googling all days but cannot find the answer. Thank you.</p> <p>This is my updated Default.aspx</p> <pre><code> &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;asp:TextBox ID="txtArtistID" runat="server" /&gt;&lt;br /&gt;&lt;br /&gt; &lt;asp:Button ID="btnSearch" runat="server" Text="Search" CssClass="submit" /&gt; &lt;div&gt; &lt;asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"&gt; &lt;Columns&gt; &lt;asp:BoundField DataField="TRANSACTIONID" HeaderText="TRANSACTIONID" SortExpression="TRANSACTIONID" /&gt; &lt;asp:BoundField DataField="WORKID" HeaderText="WORKID" SortExpression="WORKID" /&gt; &lt;asp:BoundField DataField="ARTISTID" HeaderText="ARTISTID" SortExpression="ARTISTID" /&gt; &lt;asp:BoundField DataField="DATEACQUIRED" HeaderText="DATEACQUIRED" SortExpression="DATEACQUIRED" /&gt; &lt;asp:BoundField DataField="DATESOLDID" HeaderText="DATESOLDID" SortExpression="DATESOLDID" /&gt; &lt;asp:BoundField DataField="TURNAROUNDDAYS" HeaderText="TURNAROUNDDAYS" SortExpression="TURNAROUNDDAYS" /&gt; &lt;asp:BoundField DataField="ASKINGPRICE" HeaderText="ASKINGPRICE" SortExpression="ASKINGPRICE" /&gt; &lt;asp:BoundField DataField="SALESPRICE" HeaderText="SALESPRICE" SortExpression="SALESPRICE" /&gt; &lt;asp:BoundField DataField="SALESMARGIN" HeaderText="SALESMARGIN" SortExpression="SALESMARGIN" /&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/div&gt; &lt;asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=oracle2;User ID=****;Password=****;Unicode=True" ProviderName="System.Data.OracleClient" SelectCommand="SELECT * FROM SPEEDOFSALEREPORT WHERE ARTISTID = @artistID;"&gt; &lt;SelectParameters&gt; &lt;asp:ControlParameter Name="artistID" ControlID="txtArtistID" PropertyName="Text" /&gt; &lt;/SelectParameter&gt; &lt;/asp:SqlDataSource&gt; &lt;/form&gt; &lt;/body&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
