How to display full name from combobox to textbox separated by space

I have connection with local database. I wanted full name from (in this case) combobox4 to textbox textbox. It displays this value but without separation with space. For example from combobox4 "S BOX" in textbox is only "S". I tried with textBox4.Text = string.Join(" ", parts[1]); but i couldn't work. I share my code:

I can't find any solution which may be effective. It's about string.Join construction or should create public class? Has someone idea how to solve it or explain by example code? Greetings.

Okey i've got that solution which i can do that and it's for now solved:
private void comboBox4_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox4.SelectedIndex != -1)
{
string[] parts = comboBox4.Items[comboBox4.SelectedIndex].ToString().Split(' ');
textBox10.Text = parts[0];
textBox4.Text = comboBox4.Text.Remove(0,2).Trim();

listview no data exists for the selected row/column c# InvalidOperationException

I am 100% sure my listview has data. My program will get the ID from the column 0 of my listview, connects to the database, and using the ID as my reference will get the data from my database and display it to my textboxes/comboboxes. SO when I click an item from my listview, an exception appears and all of my textboxes as well as my comboboxes are empty. I am new to c# and programming, any help will be much appreciated.

datatable won't update

I wanted to update my database that contains two text and one filename that is needed for image.
The problem is that the image and filename updates but the two other text values title and body wont be affected and don't change the previous values. Also visual studio don't get any problem and the message for executing command shows that it's executed the command but nothing except the image changes.

I've found the answer I needed this code to include my pageload reading database so it wouldn't do it when I click on the update button.I mean the problem was all about the post back thing.

myReader = myCommand.ExecuteReader();
while (myReader.Read())
{

Right click Grid view

I wanted to know if there was a way to select a row and delete on right click from grid view.
I have the delete statement but I just dont have how to select on right click.
I've seen a couple suggestions that say to use mousebuttons.right but that doesnt work for me and errors with the (mousebuttons does not exist in current context)
here is my current fill statement
