    Loop through selected items in Multiselect

    I am trying to loop through all selected items in a Multiselect and add them to an array. I am new to Coolite and I am learning that they don't function the same way the ASP controls work. I did look at the examples but am having a hard time adapting it to my needs. Any help would be greatly appreciated.

    Hi ddolan,

    Welcome!

    Here's a quick example demonstrating how to loop through the Selected ListItems during a DirectEvent.

    Example

    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
 
<script runat="server">
    protected void Button1_Click(object sender, DirectEventArgs e)
    {
        var items = "";
        
        foreach (SelectedListItem item in this.MultiSelect1.SelectedItems)
        {
            items += item.Value + "<br />";
        }

        this.Label1.Html = items;
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.NET Example</title>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        
        <ext:MultiSelect ID="MultiSelect1" runat="server">
            <Items>
                <ext:ListItem Text="Item 0" />
                <ext:ListItem Text="Item 1" />
                <ext:ListItem Text="Item 2" />
                <ext:ListItem Text="Item 3" />
            </Items>
        </ext:MultiSelect>
        
        <ext:Button runat="server" Text="Submit" OnDirectClick="Button1_Click" />
        
        <ext:Label ID="Label1" runat="server" />
    </form>
</body>
</html>
    Hope this helps.

    I was actually able to figure it out with this code.
    Dim c As New Ext.Net.ListItem.Config
            c.Text = CurrentMember.Name.Remove(0, 3)
            c.Value = CurrentMember.Properties("mail").Value.ToString
            MultiSelect1.Items.Add(New Ext.Net.ListItem(c))

 For Each a As Ext.Net.SelectedListItem In MultiSelect1.SelectedItems
    Thanks for your prompt response and the time you took to look at this. I appreciate it very much.
