SfListView - Add items manually

[Dinis Ferreira]

Hello,

SfListView only works with Data Binding?

How can I add items manually? This doesnt seems right but I've tried to add using SfListView1.SelectedItems.Add("Test") without success.

Thanks

Hi Dinis, 

Sorry for the inconvenience caused. 

We have checked your query “Need to add items in SfListItems manually in code behind without using DataSource”. Currently we do not have this support. So we are validating this request with internal team and will let you know on 11^th February 2020.

Hi Dinis, 

Thanks for your patience. 

If your data source is of type ObservableCollection, SfListView will be automatically updated when there is any change in that collection. So, if you want to add an item, you can directly add it to the data source, provided it is of type ObservableCollection.  

C#: 

public partial class Form1 : Form 

    { 

        ObservableCollection<CountryInfo> countryInfoCollection = new ObservableCollection<CountryInfo>(); 

        public Form1() 

        { 

            InitializeComponent(); 

            sfListView1.DataSource = GetDataSource(); 

            sfListView1.DisplayMember = "CountryName"; 

 

            ObservableCollection<CountryInfo> GetDataSource() 

            { 

                countryInfoCollection.Add(new CountryInfo() { CountryName = "China", Continent = "Asia" }); 

                countryInfoCollection.Add(new CountryInfo() { CountryName = "India", Continent = "Asia" }); 

                countryInfoCollection.Add(new CountryInfo() { CountryName = "Japan", Continent = "Asia" }); 

                countryInfoCollection.Add(new CountryInfo() { CountryName = "Malaysia", Continent = "Asia" }); 

                countryInfoCollection.Add(new CountryInfo() { CountryName = "Singapore", Continent = "Asia" }); 

                 

                return countryInfoCollection; 

            } 

 

        } 

       private void button1_Click(object sender, EventArgs e) 

        { 

            countryInfoCollection.Add(new CountryInfo() { CountryName = "NewCountry1", Continent = "Number1" }); 

        } 

    }
