    Hello!

    Please look at the example.

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

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Select(object sender, DirectEventArgs e)
    {
        MultiSelect1.SelectedItems.Add(new Ext.Net.SelectedListItem("Value1"));
        MultiSelect1.SelectedItems.Add(new Ext.Net.SelectedListItem("Value2"));
        MultiSelect1.SelectedItems.Add(new Ext.Net.SelectedListItem("Value3"));
        MultiSelect1.UpdateSelection();
    }
</script>

    There is a SelectedListItem constructor applied index but it doesn't work.
    I think it will be fix.

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

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Select(object sender, DirectEventArgs e)
    {
        MultiSelect1.SelectedItems.Add(new Ext.Net.SelectedListItem(0));
        MultiSelect1.SelectedItems.Add(new Ext.Net.SelectedListItem(1));
        MultiSelect1.SelectedItems.Add(new Ext.Net.SelectedListItem(2));
        MultiSelect1.UpdateSelection();
    }
</script>

            <ext:ListItem Text="Item 3" Value="Value3" />
        </Items>
    </ext:MultiSelect>
    <ext:Button runat="server" Text="Select">

    How would I get the selected values during a DirectEvent when I'm using a store like this?

    Hi,

    To get selected values you could use the SelectedItems collection.
    Please look at the example.

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

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.MultiSelect1.Store.Primary;
            store.DataSource = new object[] { 
                                         new object[] {"Value1", "Text1"},
                                         new object[] {"Value2", "Text2"},
                                         new object[] {"Value3", "Text3"}
                                };
            store.DataBind();
        }
    }

    protected void GetSelectedRows(object sender, DirectEventArgs e)
    {
        string values = "";
        foreach (SelectedListItem sli in this.MultiSelect1.SelectedItems)
        {
            values += sli.Value + " ";
        }
        X.Msg.Alert("Server", values).Show();
    }
    
</script>

    Sorry, I mean SET, not get. So, to rephrase.. how would I set the selected items when I'm using a store to populate the list?
