Found the solution. In WPF, the TextBox.TextChanged
event has a TextChangedEventArgs
. In this class, there is a property named Changes
.
Here's my code:
private void textBox1_TextChanged(object sender, TextChangedEventArgs e)
{
foreach (var change in e.Changes)
{
if (change.AddedLength > 0 && change.RemovedLength == 0)
{
if (change.AddedLength == 1)
{
AddCharacter(textBox1.Text[change.Offset], change.Offset);
}
else
{
AddString(textBox1.Text.Substring(change.Offset, change.AddedLength), change.Offset);
}
}
else if (change.AddedLength == 0 && change.RemovedLength > 0)
{
if (change.RemovedLength == 1)
{
RemoveCharacter(change.Offset);
}
else
{
RemoveString(change.Offset, change.RemovedLength + change.Offset);
}
}
else if (change.AddedLength == 1 & change.RemovedLength == 1)
{
ReplaceCharacter(change.Offset, textBox1.Text[change.Offset]);
}
else
{
ReplaceString(change.Offset, change.Offset + change.RemovedLength, textBox1.Text.Substring(change.Offset, change.AddedLength));
}
}
}
Now I just need to wait two days to accept this answer. :)
Thanks anyway.
