                <td>Kampanya Başlığı: </td>
                <td><asp:TextBox ID="txtKampanyaTitle" runat="server"></asp:TextBox></td>
            </tr>
            <tr>

                    onclick="btnAddKampanya_Click" /></td>
           </tr>
        </table>

i dont know what i write in my  btnAddKampanya_Click event

please help it is really urgent :(

Try this method.

 public void fnKampanya()
    {
        string fileName = Server.MapPath("XMLFile7.xml");//SUppose here the xml u have given is stored.
        //It is also possible to load the xml from a string
        XmlDocument xDoc = new XmlDocument();

        string userRightsXml = string.Empty;
        xDoc.Load(fileName);
        //To load xml from string used xDoc.LoadXml(strXml);
        //wher strXml is a string varibale having ur xml

        XmlNode xItem = xDoc.CreateElement("Kampanya");
       
        XmlNode xKampanya = xDoc.CreateElement("KampanyaID");
        xKampanya.InnerText = "Kamp7";

        XmlNode xKampanyaTitle = xDoc.CreateElement("KampanyaTitle");
        xKampanyaTitle.InnerText = "KampanyaAdi7";

        XmlNode xKampanyaIcerik = xDoc.CreateElement("KampanyaIcerik");
        xKampanyaIcerik.InnerText = "fdsfsdfsdj fdsfj kdsfjksd fdksf j";

        //and so on for other nodes

        xItem.AppendChild(xKampanya);
        xItem.AppendChild(xKampanyaTitle);
        xItem.AppendChild(xKampanyaIcerik);

        xDoc.DocumentElement.LastChild.AppendChild(xItem);


        string sampleOutput = xDoc.OuterXml;

       
    }

ANd on the onClik of ur button..u can call this method.. Let me know if u want more assistance.

 thanks for your answer it really helped me.

 Now i got one more question, i must say if row count of xml >9 AddButton.visible = false

it is very easy if i use stored procedure or queries but in xml i dont know how to count nodes how to put them in datatables or datasets. Please share an example about this or just say how to do this.

in my example i will count the Kampanya nodes and if it is >9 i wont let the user to add another node

THis is how u will get the count of the node Kampanya

XmlNodeList xNodeList = xDoc.SelectNodes("EvdekiKampanyalar/Kampanya");
int countCheck = xNodeList.Count

now u can do this

if(countCheck > 9 )

{

AddButton.visible = false;

}

 thanks again. You are great!!! :)

was it helpful..mark that thread as answ then.... :)

cheers!
