Hello,

I have a code to create a xml structure using System.Xml.XmlDocument class.
I want to save this datas into a native xml sql field, but I don't find the way to achive it.
Can you help me in this issue. I know there is saveTo method to save to file in a specific path, but I want to save into database.

Thanks.
XmlDocument xmldoc;

            XmlNode xmlnode;

            XmlElement xmlelem;

            
 

            xmldoc = new XmlDocument();

            //let's add the XML declaration section

            xmlnode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration, "", "");

            xmldoc.AppendChild(xmlnode);

            //let's add the root element

            xmlelem=xmldoc.CreateElement("","Sobre_B","");

            xmldoc.AppendChild(xmlelem);

            for (int sobre = 0; sobre < 3; sobre++) // 3 sobres

            {

                xmlelem = xmldoc.CreateElement("", "sobre_A", "");

                xmldoc.ChildNodes.Item(1).AppendChild(xmlelem);

                for (int pieza = 0; pieza < 4; pieza++) // 4 piezas (piezas)

                {

                    xmlelem = xmldoc.CreateElement("", "pieza", "");

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).AppendChild(xmlelem);

                    xmlelem = xmldoc.CreateElement("", "coddos", "");

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).AppendChild(xmlelem);

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).ChildNodes.Item(0).InnerText = ((pieza+1) * (sobre+1)).ToString("00000");
 

                    xmlelem = xmldoc.CreateElement("", "cousco", "");

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).AppendChild(xmlelem);

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).ChildNodes.Item(1).InnerText = ((pieza+1) * (sobre+1)).ToString("00000") + ".01";
 

                    xmlelem = xmldoc.CreateElement("", "e_Anverso", "");

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).AppendChild(xmlelem);

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).ChildNodes.Item(2).InnerText = "c:\\anverso.jpg";
 

                    xmlelem = xmldoc.CreateElement("", "e_Reverso", "");

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).AppendChild(xmlelem);

                    xmldoc.ChildNodes.Item(1).ChildNodes.Item(sobre).ChildNodes.Item(pieza).ChildNodes.Item(3).InnerText = "c:\\reverso.jpg";

There isn't much to this - just save the xml as a string (xmldoc.outerXml) to the table.

With a very trivial table (just a string name and an xml xmlitem),  I added a page to the ClubSiteExtended starter kit (not important though, the same thing would work anywhere)

The main part of the code was
        SqlDataSource1.InsertParameters["xml"].DefaultValue = xmldoc.OuterXml;
        SqlDataSource1.Insert();


The .aspx

---------------------------

<%@ Page Title="" Language="C#" MasterPageFile="~/Default.master" AutoEventWireup="true"

    CodeFile="xmls.aspx.cs" Inherits="xmls" %>
 

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

    <asp:TextBox ID="name" runat="server" />

    <asp:Button ID="run" runat="server" Text="Save" OnClick="run_Click" />

    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ClubSiteDB %>"

        InsertCommand="INSERT INTO xmlitems(name,xml) VALUES (@name, @xml)" SelectCommand="SELECT [name], [xml] FROM [xmlitems]"

        UpdateCommand="UPDATE xmlitems SET xml = @xml WHERE (name = @name)">

        <InsertParameters>

            <asp:ControlParameter ControlID="name" Name="name" PropertyName="Text" />

            <asp:Parameter Name="xml" />

        </InsertParameters>

        <UpdateParameters>

            <asp:ControlParameter ControlID="name" Name="name" PropertyName="Text" />

            <asp:Parameter Name="xml" />

        </UpdateParameters>

    </asp:SqlDataSource>

</asp:Content>

The code-behind:

using System;

    {

        XmlDocument xmldoc;

        XmlNode xmlnode;

        XmlElement xmlelem;
 
 

        xmldoc = new XmlDocument();

        //let's add the XML declaration section

        xmlnode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration, "", "");

        xmldoc.AppendChild(xmlnode);

        //let's add the root element

        xmlelem = xmldoc.CreateElement("", "Sobre_B", "");

        xmldoc.AppendChild(xmlelem);

        {

            xmlelem = xmldoc.CreateElement("", "sobre_A", "");

            xmldoc.ChildNodes.Item(1).AppendChild(xmlelem);
