Hi I know this topic has been closed long ago but i do very interested in this delete element from an xml. However i am using Datagrid possible to help me on this? 1. I am implment this xml to be able to view add and hopefully to be able to delete. 2. I realised that the method you delete the element was based on the id='1' which only delete the first element. Possible to make it to only delete the selection instead of id='1'? 3. I do hope if you are able to help me for the adding function to be able to add the id? Below is my code and hope you guys could able to help. DataSet dsxml= new DataSet (); dsxml.ReadXml( Car.xml ); DataRow newrow=dsxml.Tables[0].NewRow(); newrow[ plate ]=txtplateno.Text.ToString(); newrow[ Manufacture ]=txtmanufacture.Text.ToString(); newrow[ model ]=txtmodel.Text.ToString(); newrow[ COE ]=txtcoe.Text.ToString(); newrow[ COEExpiry ]=txtcoeexpiry.Text.ToString(); dsxml.Tables[0].Rows.Add(newrow); FileStream hew= new FileStream ( Car.xml  FileMode .OpenOrCreate FileAccess .Write FileShare .Write); dsxml.WriteXml(hew); hew.Close(); MessageBox .Show( Data Updated ); this .dsxml= new DataSet ( car id='' ); this .dsxml.ReadXml( Car.xml ); this .dataGrid.DataSource= this .dsxml; this .dataGrid.DataMember= car ; this .txtplateno.Text=  ; this .txtmanufacture.Text=  ; this .txtmodel.Text=  ; this .txtcoe.Text=  ; this .txtcoeexpiry.Text=  ;
