Update text in textboxes from selected item in listbox. Listbox works fine
Question
I built a WinForm app that works fine with SQL database stored online. I am now trying to move to asp.net app. After learning everything I needed to build the WinForm app I am frustrated over new learning curve!
This is a basic app that has a listbox with all people in the database. The listbox display the combined NameLast + ', ' + NameFirst as NameFull showing something like “Smith, John”. When the user selects a person the textboxes should display the related information. Once I get started it should be easy however… How do I build a OnSelectedChanged type command to fill the textboxes. In this example I would have four (4) textboxes: NameFirstTxt, NameMiddleTxt, NameLastTxt and RecordIDTxt.
I have attached code from the WinForm app used during the selected index change event. Any advice and comments (good or bad) would be helpful. Thank you in advance.

Make sure the AutoPostback property of ListBox is set to true.
Aspx Code:
<asp:ListBox ID="ListBox1" runat="server" OnSelectedIndexChanged="ListBox1_SelectedIndexChanged"
AutoPostBack="True">
<asp:ListItem>1st Person</asp:ListItem>
<asp:ListItem>2nd Person</asp:ListItem>
<asp:ListItem>3rd person</asp:ListItem>
</asp:ListBox>
<br />
FIRST NAME:<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
LASTNAME:<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<br />
EMAIL:<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
Code behind:
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
foreach (ListItem li in ListBox1.Items)
{
if (li.Selected == true)
{
// what ever you want to assign to TextBox
this.TextBox1.Text = li.Text + "First Name"; // (row["NameFirst"]).ToString();
this.TextBox2.Text = li.Text + "Last Name";
this.TextBox3.Text = li.Text + "Email";
}
}
}
