Here consider we have a list of Employee Details ,first we will fetch the details
for a particular employee into text boxes then edit them and update them to the list
using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.SharePoint; using Microsoft.SharePoint.Client; namespace EmployeeDetailsEdit { public partial class MainPage : UserControl { ClientContext cc1; ListItem litem; List EmployeeDetails; ListItemCollection _icoll; string tmp, Title, EmployeeName, JoinDate,Address; public MainPage() { InitializeComponent(); cc1 = new ClientContext(ApplicationContext.Current.Url); cc1.Load(cc1.Web); EmployeeDetails = cc1.Web.Lists.GetByTitle("EmployeeDetails"); cc1.Load(EmployeeDetails ); CamlQuery qry = new Microsoft.SharePoint.Client.CamlQuery(); string q = ""; qry.ViewXml = q; _icoll = auditp.GetItems(qry); cc1.Load(_icoll); cc1.ExecuteQueryAsync(new ClientRequestSucceededEventHandler(sucess), null); } private void SubmitButton_Click(object sender, RoutedEventArgs e) { litem = EmployeeDetails.GetItemById(ID); litem["Title"] = textBox1.Text; litem["Employee_x0020_Name"] = textBox2.Text; litem["Join_x0020_Date"] = datePicker1.Text.ToString(); litem["Address"] = textBox3.Text; litem.Update(); cc1.Load(EmployeeDetails, list => list.Title); cc1.ExecuteQueryAsync(sucess, null); } private void sucess(Object sender, ClientRequestSucceededEventArgs args) { // This is not called on the UI thread. Dispatcher.BeginInvoke(datafetch); } private void datafetch() { foreach (ListItem l in _icoll) { if (l["Employee_x0020_Name"].ToString() == "Joseph") { tmp = l["ID"].ToString(); Title= l["Title"].ToString(); EmployeeName= l["Employee_x0020_Name"].ToString(); JoinDate= l["Join_x0020_Date"].ToString(); Address= l["Address"].ToString(); } } ID = Convert.ToInt32(tmp); textBox1.Text = Title; textBox2.Text = EmployeeName; datePicker1.Text = JoinDate; textBox3.Text = Address;} } } }
