Crystal Report ASP.Net Example using DataSet or DataTable in C# VB.Net and Visual Studio 2010

You need right click on the rpt -> Insert and add text object inside section 2 for displaying the From and To date.


<asp:TextBox ID="txtFromDate" runat="server"></asp:TextBox>
<asp:TextBox ID="txtToDate" runat="server"></asp:TextBox>
<asp:Button ID="btnSearch" runat="server" Text="Search" OnClick="Search" />
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true" />
