Cannot get new check items

[Ei Wai]

Hi all,

I can't get new check items on code behind. I bind the listbox on page load.

<telerik:RadListBox ID="listBoxEmp" runat="server" CheckBoxes="true" ShowCheckAll="true"
                                            Width="250px" Height="200px" >

.cs

List<tbl_Employee> data = GetEmp("");
       if (data != null)
       {
           for (int i = 0; i < data.Count; i++)
               listBoxEmp.Items.Add(new RadListBoxItem(data[i].ID.ToString() + " | " + data[i].Name.ToString(), data[i].ID.ToString()));

       }

 
There will be other comboboxs. I have to check items based on other combobox selection. So in codebehind,  I do it like this. It will checked all items that returned from query.

foreach (RadListBoxItem cbi in listBoxEmp.Items)
       {
           if (objEmp.Where(x => x.EmployeeID == cbi.Value).Count() > 0 && cbi.Checked == false)
           {
               cbi.Checked = true;
               //checkEmp += cbi.Value + ",";
           }
       }

After that I also check some more items from the UI but when I click search,new items are not inside the listBoxEmp.CheckedItems list. Please suggest.

Thank you.

Best regards,
Ei Wai

Hi Ei,

From the provided information only it is not clear what your exact scenario and issues are, so can you please elaborate a little more on them. I would also would like to ask you to provide a very simplified example with the issue, so we can test it locally.

Looking forward to your reply.
