I have created a ListView with multiple columns

(This is a part of the Xaml)

"100" Header="Indexer" DisplayMemberBinding="{Binding Number}"/> "100" Header="Name" DisplayMemberBinding="{Binding NameId}"/> "100" Header="Age" DisplayMemberBinding="{Binding Age}"/>

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)

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);

proceed like below
int i=0;
foreach (ListViewItem lvi in listView1.Items)
{
   if (lvi.SubItems[i].Text=="Text for search")
     MessageBox.Show("!!!!!!!");
i++;
}

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>

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 < 0)
    {
        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");
}
