Answer 1

In the out put you can see that English Columns on LTR and Arabic Column on RTL. if you want to display GridView on page with RTL than you can use <div dir="rtl">Put the Grid View here</div>. GridView:

 <asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="False">
        <Columns>
            <asp:TemplateField HeaderText="العربية" SortExpression="العربية">
                <ItemTemplate>
                    <asp:Label ID="arabic" runat="server" Text='<%# Eval("العربية")%>' />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        <Columns>
            <asp:TemplateField HeaderText="English" SortExpression="English">
                <ItemTemplate>
                    <asp:Label ID="english" runat="server" Text='<%# Eval("English") %>' />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:Button ID="deleteButton" runat="server" Text="Delete" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:HyperLink ID="open" runat="server" Text="Open" NavigateUrl="~/Default.aspx"/>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
        SelectCommand="SELECT [English], [العربية] FROM [Test]"></asp:SqlDataSource>
    <br />
    <asp:Button ID="btnExport" runat="server" OnClick="btnExport_Click" Text="Export to PDF" />

CS Code:

            _table.CompleteRow();
        }
        PdfWriter.GetInstance(document, Response.OutputStream);
        // Opens the document.
        document.Open();
        // Adds the _table to the document.
        document.Add(_table);
        // Closes the document.
        document.Close();
        Page.Response.ContentType = "application/pdf";
        Page.Response.AddHeader("content-disposition", "attachment;filename=MyGrid.pdf");
        Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Page.Response.Write(document);
        Page.Response.End();

    }

This code might not be the perfectly coded but I hope this will help you to get your required results.

This GridView exporting library supports RTL. Also you can try PdfReport library as well.
