Split words in textboxes vb.net

Can some tell me how to overcome this problem? I'm trying to separate the words but there's whitespaces remaining in FirstName and MiddleName.
Sample image

Here's my code

Dim str As String = ListView1.Items(ListView1.SelectedIndices(0)).SubItems(2).Text
Dim splitStr As String() = str.Split(","c)
txtLastName.Text = splitStr(0).ToString()
txtFirstName.Text = splitStr(1).ToString()
txtMiddleInitial.Text = splitStr(2).ToString()


Is my code missing some info?

Can you tell the exact code I'm going to use? Thank you.

To remove white-space characters from the start and end of a String I would use String.Trim:

Removes all leading and trailing white-space characters from the current String object.

To do this in your code simply append .Trim() to the end of your String:

Dim str As String = ListView1.Items(ListView1.SelectedIndices(0)).SubItems(2).Text
Dim splitStr As String() = str.Split(","c)
txtLastName.Text = splitStr(0).ToString().Trim()
txtFirstName.Text = splitStr(1).ToString().Trim()
txtMiddleInitial.Text = splitStr(2).ToString().Trim()

As a side note since splitStr(.) is already a String you don't need to use ToString():

txtLastName.Text = splitStr(0).Trim()
txtFirstName.Text = splitStr(1).Trim()
txtMiddleInitial.Text = splitStr(2).Trim()

To test, this was my code:

Dim str As String = "LOWELL, JOHN, F"
Dim splitStr As String() = str.Split(","c)

TextBox1.Text = splitStr(0)
TextBox2.Text = splitStr(1)
TextBox3.Text = splitStr(2)

TextBox4.Text = splitStr(0).Trim()
TextBox5.Text = splitStr(1).Trim()
TextBox6.Text = splitStr(2).Trim()

This is my output:

The TextBox order is the same as the code. You can see where the white-space has been removed from the bottom set using .Trim().
