If you finally came over to the dark side and embraced Silverlight in SharePoint you should familarize yourself with the Client API for Silverlight, I have mentioned in a previous post how to reference these assemblies.
If you want to be more adventourous and insert list items using the Client API you can use the following code:
ClientContext context = ClientContext.Current;
List oList = context.Web.Lists.GetByTitle("HelloWorldList");
ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();
ListItem oListItem = oList.AddItem(itemCreateInfo);
oListItem["Title"] = "Hello World";
oListItem.Update();
context.Load(oList, list => list.Title);
context.ExecuteQueryAsync(OnSuccess, OnFailed);
The above method is done assyncrously so you will have a call back which means if the insert is success code sample A if it is unsuccessful run code sample B, see below:
private void onSuccess(object sender, ClientRequestSucceededEventArgs args)
{
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
MessageBox.Show("successfull");
});
}
private void onFailed(object sender, ClientRequestFailedEventArgsargs)
{
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
MessageBox.Show("Failed");
});
}
As you know these operations are done assyncronously so simply put we have to get the attention of the UI thread to perform our success or failure action.
Happy coding :-)
