Examples

Here is how to use a SearchGlobal in the C# code:

using System.Collections.Generic;
using System.Windows.Controls;

using Alternet.Editor;

public partial class MainWindow : Window
{
    private IDictionary<TabItem, TextEditor> editors = new Dictionary<TabItem, TextEditor>();

    private void Window_Loadeded(object sender, System.Windows.RoutedEventArgs e)
    {
        void NewEditor(string fileName)
        {
            TabItem page = new TabItem();
            page.Header = fileName;
            tcEditors.Items.Add(page);
            TextEditor edit = new TextEditor();
            editors.Add(page, edit);
            page.Content = edit;
            edit.LoadFile(fileName);
        }
        NewEditor("myfile1.txt");
        NewEditor("myfile2.txt");
        NewEditor("myfile3.txt");

        SearchManager.SharedSearch.InitSearch += new InitSearchEvent(DoInitSearch);
        SearchManager.SharedSearch.GetSearch += new GetSearchEvent(DoGetSearch);
    }

    private TextEditor GetEditor(TabItem key)
    {
        TextEditor result;
        if (key != null && editors.TryGetValue(key, out result))
            return result;
        return null;
    }

    private void UpdateSearch()
    {
        TextEditor edit = GetEditor(tcEditors.SelectedItem as TabItem);
        if (edit != null)
        {
            ISearch search = (ISearch)edit;
            search.SearchGlobal = true;
        }
    }

    private void DoInitSearch(object sender, InitSearchRoutedEventArgs e)
    {
        e.Search = GetEditor(tcEditors.SelectedItem as TabItem);
        foreach (TextEditor edit in editors.Values)
        {
            edit.SearchGlobal = true;
            if (edit.Source != null)
                e.SearchList.Add(edit.Source.FileName);
        }
    }

    private void DoGetSearch(object sender, GetSearchRoutedEventArgs e)
    {
        foreach (TabItem page in editors.Keys)
        {
            TextEditor edit = GetEditor(page);
            if (edit != null && string.Compare(edit.Source.FileName, e.FileName, true) == 0)
            {
                tcEditors.SelectedItem = page;
                UpdateSearch();
                e.Search = (ISearch)edit;
                break;
            }
        }
    }

}

Here is how to use a SearchGlobal in the Visual Basic code:

Imports System.Collections.Generic
Imports System.Windows.Controls
Imports Alternet.Editor

Partial Public Class MainWindow

    Private editors As IDictionary(Of TabItem, TextEditor) = New Dictionary(Of TabItem, TextEditor)()

    Private Sub NewEditor(ByVal fileName As String)
        Dim page As TabItem = New TabItem()
        page.Header = fileName
        tcEditors.Items.Add(page)
        Dim edit As TextEditor = New TextEditor()
        editors.Add(page, edit)
        page.Content = edit
        edit.LoadFile(fileName)
    End Sub

    Private Sub Window_Loadeded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs)
        NewEditor("myfile1.txt")
        NewEditor("myfile2.txt")
        NewEditor("myfile3.txt")
        AddHandler SearchManager.SharedSearch.InitSearch, New InitSearchEvent(AddressOf DoInitSearch)
        AddHandler SearchManager.SharedSearch.GetSearch, New GetSearchEvent(AddressOf DoGetSearch)
    End Sub

    Private Function GetEditor(ByVal key As TabItem) As TextEditor
        Dim result As TextEditor
        If key IsNot Nothing AndAlso editors.TryGetValue(key, result) Then Return result
        Return Nothing
    End Function

    Private Sub UpdateSearch()
        Dim edit As TextEditor = GetEditor(TryCast(tcEditors.SelectedItem, TabItem))

        If edit IsNot Nothing Then
            Dim search As ISearch = CType(edit, ISearch)
            search.SearchGlobal = True
        End If
    End Sub

    Private Sub DoInitSearch(ByVal sender As Object, ByVal e As InitSearchRoutedEventArgs)
        e.Search = GetEditor(TryCast(tcEditors.SelectedItem, TabItem))

        For Each edit As TextEditor In editors.Values
            edit.SearchGlobal = True
            If edit.Source IsNot Nothing Then e.SearchList.Add(edit.Source.FileName)
        Next
    End Sub

    Private Sub DoGetSearch(ByVal sender As Object, ByVal e As GetSearchRoutedEventArgs)
        For Each page As TabItem In editors.Keys
            Dim edit As TextEditor = GetEditor(page)

            If edit IsNot Nothing AndAlso String.Compare(edit.Source.FileName, e.FileName, True) = 0 Then
                tcEditors.SelectedItem = page
                UpdateSearch()
                e.Search = CType(edit, ISearch)
                Exit For
            End If
        Next
    End Sub
End Class

Remarks

Search and replace operations may be configured to be across multiple text documents. It's beneficial for searching for occurrences of the text within all files in the projects.

Set SearchGlobal to true to enable this feature. In this case, search and replace functionality is provided by the SearchManager instead of the particular TextEditor control instance.
