MultiCombo not returning any selected items

Hi Ext.NET,
In Page_Load i am filling MultiCombo control and selecting all the items by using MultiCombo.SelectAll() method. After this need to do another opearation based on the items selected in MultiCombo.
But its not returning any values in SelectedItems property even MultiCombo.Items also empty in the same event.

After completing loading if i refresh the page its working fine.

How to get the selected item values in pageload itself?

ASPX Code

Code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Sample.WebForm1" %> <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <ext:ResourceManager ID="ResourceManager1" runat="server"> </ext:ResourceManager> <div> <ext:MultiCombo ID="MultiCombo" runat="server" DisplayField="State" ValueField="StateID"> <Store> <ext:Store ID="storeMultiCombo" runat="server"> <Reader> <ext:JsonReader IDProperty="StateID"> <Fields> <ext:RecordField Name="StateID" /> <ext:RecordField Name="State" /> </Fields> </ext:JsonReader> </Reader> </ext:Store> </Store> </ext:MultiCombo> </div> </form> </body> </html>

CODE BEHIND

Code:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace Sample { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { List<States> states = new List<States>(); states.Add(new States { State = "State1", StateID = 1 }); states.Add(new States { State = "State2", StateID = 2 }); states.Add(new States { State = "State3", StateID = 3 }); this.MultiCombo.GetStore().DataSource = states; this.MultiCombo.GetStore().DataBind(); this.MultiCombo.SelectAll(); int n = this.MultiCombo.SelectedItems.Count; // returns 0 int m = this.MultiCombo.Items.Count; // returns 0 } } public class States { public string State { get; set; } public int StateID { get; set; } } }

Hi,

SelectAll just generates for selecting items on the client side, it doesn't select any items in the server side
SelectedItems is updated when you submit from from the client (directevent,directmethod or postback)

Just add button with direct event, click on it and you will see selected items on the server side
Also I suggest to wrap code in the page load by 'if(!X.IsAjaxRequest){...}'

Mmm.. I have just followed your suggestion above.. But still not works Vladimir.. :-/
This is my simple code :

Code:

<ext:Button runat="server" ID="lnkBtnEditUser" Text="Ubah Data Pengguna" Icon="UserEdit"> <DirectEvents> <Click OnEvent="lnkBtnEditUserx_Click" After="UserManagementX.InitializeControl();"> <ExtraParams> <ext:Parameter Name="ParentGrid" Value="Ext.encode(#{grdPnlUserList}.getRowsValues({selectedOnly : true}))" Mode="Raw" /> </ExtraParams> </Click> </DirectEvents> </ext:Button>

Code:

protected void lnkBtnEditUserx_Click(object sender, DirectEventArgs e) { string tmpUserGroupDetail = string.Empty; foreach (DataRow dr in dataUserGroupDetail.Rows) { var tmp = listGroups.Find(y => y.Value.Equals(dr["GroupId"])); this.multiCmbRoles.SelectedItems.Add(tmp); tmpUserGroupDetail = string.Concat(dr["GroupName"], ",", tmpUserGroupDetail); } }
