                                        </ext:Store>
                                        
                                      
                                    </Store>
                                  
                                    </ext:MultiCombo>
    Here is the code where I am trying to highlight some of the items in multiselect combo from code behind, on a grid row select event.:
    ---------------------------------------------------------------------------------------------------------------------------------------------------------



     protected void ProjectSelect(object sender, DirectEventArgs e) // use this for populatg prj form if prj grid row is selected.
            {
    .
    .
    .
    .
    
     Dictionary<string, string>[] grid1Data = JSON.Deserialize<Dictionary<string, string>[]>(response);
                
    
                        if (grid1Data.Count() > 0)
                        {
                            Ext.Net.ListItem lt = new Ext.Net.ListItem();
                            foreach (var record in grid1Data)
                            {
                                repProgramID = (record["PROGRAM_ID"]);
                                object RepPgmID = Convert.ToInt32(repProgramID);
                              
                                this.ddlRepPrograms.SelectedItems.Add(new Ext.Net.ListItem(record["PROGRAM_NAME"]));
                               
             
                            
                            }
    
                        }
    
                        else
                        {
                            this.ddlRepPrograms.Select("No Program");
                
                        }
    .
    .
    .
    .

    The attached screenshot shows 4 options in multicombo:

    No Program, Test 1, test 2, zzzzzzz

    I want test 1 and test 2 selected in multicombo, on grid row select event in Museum Projects grid.

    when i try the above, still it shows the multicombo unselected with those items.., as it was on page load.


    pls help me resole this asap.

    Thanks,
    Veda

    Hi Veda,

    Please try to call:
    this.ddlRepPrograms.UpdateSelectedItems();
    after modifying the SelectedItems collection.

    Hello!

    I tried the code below and it works fine. Can you provide your sample to reproduce?

    <%@ 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)
            {
                Store1.DataSource = new object[]
                    {
                        new { REP_PROGRAM_ID = 1, REP_PROGRAM_NAME = "Program 1"},
                        new { REP_PROGRAM_ID = 2, REP_PROGRAM_NAME = "Program 2"},
                        new { REP_PROGRAM_ID = 3, REP_PROGRAM_NAME = "Program 3"}
                    };
                Store1.DataBind();
            }
        }
    
        protected void ProjectSelect(object sender, DirectEventArgs e)
        {
            this.ddlRepPrograms.SelectedItems.Add(new Ext.Net.ListItem(1));
            this.ddlRepPrograms.UpdateSelectedItems();
        }
