Selecting a Row from List View throws an error
Jan 25 2020 12:49 AM
Hi,
I have a list view that pulls records from a Database, and that works.
I want to select a row and pass the record Name, Number and Date to three Text Boxes.
With the code I have, I can do that just fine, but just once. I select the customer from a listbox, then it displays that customer's records in a seperate listview.
If there are no records, there is no problem.
If there is one record, there is no problem.
If there is more than one record, I can click on any record in the list, and it passes the Name, Number and Date to my textboxes, which is what I want.
But, here is the problem, if I select a second record then it throws this error:
System.ArgumentOutOfRangeException: 'InvalidArgument=Value of '0' is not valid for 'index'.
Parameter name: index'
This is my code which retrieves the records from my database and populates listView1 (this works just fine):
try
{
conDataBase3.Open();
myReader = cmdDataBase.ExecuteReader();
while
(myReader.Read())
{
ListViewItem item =
new
ListViewItem(myReader[
"RUAName"
].ToString());
item.SubItems.Add(myReader[
"RUANumber"
].ToString());
item.SubItems.Add(myReader[
"RUAExpiryDate"
].ToString());
listView1.Items.Add(item);
}
Now this is the code that works just fine once, but crashes with the above error if I select a second record:
private
void
listView1_SelectedIndexChanged(
object
sender, EventArgs e)
{
string
lvname = listView1.SelectedItems[0].SubItems[0].Text;
string
lvnumber = listView1.SelectedItems[0].SubItems[1].Text;
string
lvdate = listView1.SelectedItems[0].SubItems[2].Text;
textBox2.Text = lvname;
textBox1.Text = lvnumber;
dateTimePicker1.Text = lvdate;
}
Any suggestions would be appreciated,
Thank you!
