You should use the Client Side Object Model to interact with SharePoint Online from your ASP.Net App.

First, you should add the below references to your solution

  • Microsoft.SharePoint.Client.dll
  • Microsoft.SharePoint.Client.Runtime.dll

Add List Item

string WebUrl = "https://You.sharepoint.com/sites/ABC/";
string login = "**********";
string password = "**********";
var securePassword = new SecureString();
foreach (char c in password)
    {securePassword.AppendChar(c);}
var onlineCredentials = new SharePointOnlineCredentials(login, securePassword);
#endregion

#region Insert the data
using (ClientContext CContext = new ClientContext(WebUrl))
{
CContext.Credentials = onlineCredentials;
List announcementsList = CContext.Web.Lists.GetByTitle("Supply GateWay");
ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();
Microsoft.SharePoint.Client.ListItem newItem = announcementsList.AddItem(itemCreateInfo);
newItem["Title"] = C_Name.Value;
newItem["Address"] = C_Address.Value;
newItem.Update();
CContext.ExecuteQuery();
}

This is a good template with CRUD function in asp.net gridview by asp:TemplateField with control events(OnRowDeleting/OnRowEditing/OnRowUpdating etc.).

You could achieve insert function in footer template also, follow this official demo.

Hope this would help you.
