Description
RadSyntaxEditor is purposed to provide editing options for a document loaded in the control. A common requirement is to save the changes that have been made to the document.
Solution
This solution demonstrates how to get very easily the document's content by using the selection functionality and write the content to a file:
public RadForm1()
{
InitializeComponent();
using (StreamReader Reader = new StreamReader(@"..\..\Sample.cs"))
{
this.radSyntaxEditor1.Document = new TextDocument(Reader);
}
}
private void radButton1_Click(object sender, EventArgs e)
{
this.radSyntaxEditor1.SelectAll();
string selectedText = this.radSyntaxEditor1.SyntaxEditorElement.Selection.GetSelectedText();
string fileName = @"..\..\FILENAME.txt";
if (!File.Exists(fileName))
{
File.Create(fileName).Close();
using (StreamWriter sw = File.AppendText(fileName))
{
sw.WriteLine(selectedText);
}
}
else
{
File.WriteAllText(fileName, string.Empty);
using (StreamWriter sw = File.AppendText(fileName))
{
sw.WriteLine(selectedText);
}
}
}
Sub New()
InitializeComponent()
Using Reader As StreamReader = New StreamReader("..\..\Sample.cs")
Me.RadSyntaxEditor1.Document = New TextDocument(Reader)
End Using
End Sub
Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
Me.RadSyntaxEditor1.SelectAll()
Dim selectedText As String = Me.RadSyntaxEditor1.SyntaxEditorElement.Selection.GetSelectedText()
Dim fileName As String = "..\..\FILENAME.txt"
If Not File.Exists(fileName) Then
File.Create(fileName).Close()
Using sw As StreamWriter = File.AppendText(fileName)
sw.WriteLine(selectedText)
End Using
Else
File.WriteAllText(fileName, String.Empty)
Using sw As StreamWriter = File.AppendText(fileName)
sw.WriteLine(selectedText)
End Using
End If
End Sub
