how to see if Listview column contains a specific name

Question

I have created a ListView with multiple columns

(This is a part of the Xaml)

<ListView.View> <GridView> <GridViewColumn Width="100" Header="Indexer" DisplayMemberBinding="{Binding Number}"/> <GridViewColumn Width="100" Header="Name" DisplayMemberBinding="{Binding NameId}"/> <GridViewColumn Width="100" Header="Age" DisplayMemberBinding="{Binding Age}"/> </GridView> </ListView.View>

cs part:

public class MyItem {
public int Number { get; set; }
public int Age { get; set; }
public string NameId { get; set; }
}

i know how to add a new item to a specific column:

AccountList.Items.Add(new MyItem { Age = Convert.ToInt32(AgeVAlue), NameId = NameValue.ToString(), Number = ListCount });

how do i check if NameId contains a spefic word because i cannot do this:

AccountList.Items.Contains(SpecificWord)

Hi Zosar, Try this code: public class MyItem { public int Number { get ; set ; } public int Age { get ; set ; } public string Name { get ; set ; } public class MainViewModel : NotificationObject { public MainViewModel() { SearchMyItem = new DelegateCommand( this .OnSearchMyitem); AccountList.Add( new MyItem { Age =21, Name = "Magesh" , Number = 1}); AccountList.Add( new MyItem { Age =24, Name = "Karthik" , Number = 2}); } private List AccountList = new List (); private string _searchString; public string SearchString { get { return _searchString; } set { _searchString = value; RaisePropertyChanged(() => SearchMyItem); } } private ICollectionView _person; public ICollectionView Person { get { return CollectionViewSource.GetDefaultView(AccountList); } } public ICommand SearchMyitem { get ; private set ; } private void OnSearchMyitem() { if (! string .IsNullOrEmpty(SearchString)) { Person.Filter = (item) => { return (item as Myitem).Name.StartsWith(SearchString) ? true : false ; }; } else Person.Filter = null ; } } XAML: Grid > Grid.RowDefinitions > RowDefinition Height = "30" /> RowDefinition Height = "*" /> Grid.RowDefinitions > StackPanel Orientation = "Horizontal" > TextBox Text = "{Binding SearchString}" Width = "150" /> Button Content = "Search" Command = "{Binding SearchMyItem}" /> StackPanel > ListView Grid.Row = "1" ItemsSource = "{Binding MyItem}" > ListView.View > GridView > GridView.Columns > GridViewColumn Header = "Indexer" DisplayMemberBinding = "{Binding Number}" /> GridViewColumn Header = "Name" DisplayMemberBinding = "{Binding Name}" /> GridViewColumn Header = "Age" DisplayMemberBinding = "{Binding Age}" /> GridView.Columns > GridView > ListView.View > ListView > Grid >

Thank you for the help. Mageshwaran R could you explain your code please I am new to C# and im trying to learn everything i understand the: if else statements, arrays, methods, classes, objects, lists and some linq and lambda expressions just the simple basic stuff. but i see allot of things that i do not understand at all: from line 22 to 37: this is the part that confuses me allot i do not understand it at all. private string _searchString; public string SearchString { get { return _searchString; } set { _searchString = value; RaisePropertyChanged(() => SearchMyItem); } } private ICollectionView _person; public ICollectionView Person { get { return CollectionViewSource.GetDefaultView(AccountList); } } public ICommand SearchMyitem { get ; private set ; } private void OnSearchMyitem() { and here i assume you are creating a object? SearchMyItem = new DelegateCommand( this .OnSearchMyitem);

Hello osyris, try below and refer articles. private void FindItemButton_Click( object sender, EventArgs e) { ListView1.ClearSelected(); int index = ListView1.FindString(textBox1.Text); if (index { MessageBox.Show( "Item not found." ); textBox1.Text = String.Empty; } else { ListView1.SelectedIndex = index; } } https://www.c-sharpcorner.com/UploadFile/mahesh/working-with-listview-in-C-Sharp/ void findButton_Click( object sender, EventArgs e) { // Call FindItemWithText, sending output to MessageBox. ListViewItem item1 = findListView.FindItemWithText( "brack" ); if (item1 != null ) MessageBox.Show( "Calling FindItemWithText passing 'brack': " + item1.ToString()); else MessageBox.Show( "Calling FindItemWithText passing 'brack': null" ); }
