RadListBox doesn't check multiple item

[Mohammad Irwan]

I have a saved the multiple checked items into my database, when I retrieve out the records, it only checked one item in the listbox instead of multiple. I have also verified that the records returned in the datatable contains 3 records.

aspx:
 <telerik:RadListBox ID="lbxDevelopmentComponent" SelectionMode="Multiple" runat="server" OnClientItemChecked="OnClientItemChecked"
                                        CheckBoxes="true" DataTextField="Text" DataValueField="Value" Width="500px" Height="150px">
                                    </telerik:RadListBox>

.cs:
var dtDevelopmentComponent = _objSqlManager.ExecuteSQL(sqlDevelopmentComponent.ToString(), paramDevelopmentComponent);

                        if (dtDevelopmentComponent.Rows.Count > 0)
                        {
                            for (int i = 0; i < dtDevelopmentComponent.Rows.Count; i++)
                            {
                                RadListBoxItem item = lbxDevelopmentComponent.FindItemByText(dtDevelopmentComponent.Rows[0]["DEVELOPMENT_COMPONENT_NAME"].ToString());
                                if (item != null)
                                    item.Checked = true;
                            }
                        }

Hi,

I've attached a small sample page, where with the click of a button several items in the ListBox are checked simultaneously, which works fine on my end.
