Hello all,
I have done a demo of " export to PDF" ,like the Grid / Export to PDF.
I downloaded the PDF,when i open it ,it can't open or sometimes it opened but had nothing. I don't know why.
my code like follows:

    
            <body> 
        
                <form id="form1" runat="server">  
        
                <div  style="height: 110px; width: 92%">  
        
                        <asp:CheckBox ID="CheckBox1" Text="Export only data" runat="server"></asp:CheckBox> 
        
                        <br /> 
        
                        <asp:CheckBox ID="CheckBox2" Text="Ignore paging (exports all pages)" runat="server"></asp:CheckBox> 
        
                        <br /> 
        
                        <asp:CheckBox ID="CheckBox3" Text="Open exported data in new browser window" runat="server"></asp:CheckBox> 
        
                        <br /> 
        
                        <br /> 
        
            <asp:Button ID="Button1"  Width="150px" Text="Export to Excel" OnClick="Button1_Click" 
        
            runat="server"></asp:Button>
