Gridview is not appearing.What is my mistake?
-
With the WHERE clause, the gridview is not appearing and without it, it is appearing? Why is it so? This is my code. <%@ Page Language="VB" AutoEventWireup="false" CodeFile="daily_report_console.aspx.vb" Inherits="daily_report_console" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-… <html> <head> <title>Daily Report</title> <style type="text/css"> .style1 { width: 404px; } </style> </head> <body> <form id="form1" runat="server"> <center> <table border="2" cellspacing="0" cellpadding="30" width="" style="border-color:#336699"> <tr> <td align="center" class="style1"> <table border="0" cellspacing="0" cellpadding="10"> <td><img src="image/DRC.jpg" alt="Extolcorp MSC Bhd" /></td> </tr> <tr> <td><center> <asp:Calendar ID="Calendar1" runat="server" BackColor="White" BorderColor="White" BorderWidth="1px" Font-Names="Verdana" Font-Size="9pt" ForeColor="Black" Height="190px" NextPrevFormat="FullMonth" Width="350px"> <DayHeaderStyle Font-Bold="True" Font-Size="8pt" /> <NextPrevStyle Font-Bold="True" Font-Size="8pt" ForeColor="#333333" VerticalAlign="Bottom" /> <OtherMonthDayStyle ForeColor="#999999" /> <SelectedDayStyle BackColor="#333399" ForeColor="White" /> <TitleStyle BackColor="White" BorderColor="Black" BorderWidth="4px" Font-Bold="True" Font-Size="12pt" ForeColor="#333399" /> <TodayDayStyle BackColor="#CCCCCC" /> </asp:Calendar> </td> </center> </tr> <tr> <td> <asp:Button ID="Button1" runat="server" Text="Back" Width="95px" />  <asp:TextBox ID="TextBox1" runat="server">Select Date</asp:TextBox>  <asp:Button ID="Button2" runat="server" Text="Get Report" Width="95px"/> </td> </tr> </table> </table> <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" Visible="False"> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:guestConnectionString2 %>" ProviderName="<%$ ConnectionStrings:guestConnectionString2… %>" SelectCommand="SELECT id, date, f_name, l_name, person_2_meet, time_entered, time_exited, email FROM guest WHERE DATE(date) = DATE(NOW())"> <SelectParameters> <asp:ControlParameter ControlID="TextBox1" DefaultValue="%" Name="date" PropertyName="Text" Type="String" /> </SelectParameters> </asp:SqlDataSource> </form> </body> </html>

Answer:
With your WHERE clause, your query may be returning no results, so the gridview hides itself. You could add an empty row if you want to force it be visible.
