    text
    copied!<p>I have a ListBox which is populated dynamically from a database in the code behind. I have another button and when i click the button, the button click event will get the all the selected listitem and insert the list item text to the database. I set AutoPostBack as false and EnableViewState is true in the listbox property</p> <p>The problem is when i click the button , it only see 1 selected item even i select multiple items.Here are the codes. I appreciate your help. I spend 1 day on this issue and not getting anywhere.</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { loadrdlist(); } } protected void loadrdlist() { ((ListBox)TestFormView.FindControl("ListBoxB")).Items.Clear(); foreach (FailureTempRD rd in FailureTempRD.SelectFailureTempRD()) ((ListBox)TestFormView.FindControl("ListBoxB")).Items.Add(new ListItem(rd.ReferenceDesignator, rd.ReferenceDesignator)); } protected void btn_AddRD_Click(object sender, EventArgs e) { foreach (ListItem rd in ((ListBox)TestFormView.FindControl("ListBoxB")).Items) //This is where it only see 1 selected item { if (rd.Selected == true) //put selected item to database } } } </code></pre> <p>Here are both listbox and button</p> <pre><code>&lt;asp:ListBox ID="ListBoxB" runat="server" SelectionMode="Multiple" &gt;&lt;/asp:ListBox&gt; &lt;asp:Button ID="btn_AddRD" runat="server" CausesValidation="False" onclick= "btn_AddRD_Click" Text="Add" /&gt; </code></pre> <p>Update : I figure why. When i load the listitem, i need to add ID as listitem value. So change the following code. I test few times and it works as intend.</p> <pre><code> ((ListBox)TestFormView.FindControl("ListBoxB")).Items.Add(new ListItem(rd.ReferenceDesignator, rd.ReferenceDesignator)); </code></pre> <p>To</p> <pre><code> ((ListBox)TestFormView.FindControl("ListBoxB")).Items.Add(new ListItem(rd.ReferenceDesignator, rd.ID)); </code></pre>

An individual column

Larger individual text columns get their own page to allow for proper reading.
