How to Show/Hide Rad Combobox items based on array row value in Itemdatabound

[gc_0620]

Folks,

I am using VS2010 with RadControls for ASP.NET AJAX Q2 2012 SP1. I would like to hide certain ComboBox items based on Values from an array. Below is my complete code. Any help will be appreciated.
Thanks

        <telerik:RadComboBoxItem runat="server" Text="Florida" Value="Florida" />

        <telerik:RadComboBoxItem runat="server" Text="Wisconsin" Value="Wisconsin" />
    </Items>
</telerik:RadComboBox>

.........

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  string[] retrievedLocations = (string[])Session["LocationData"];
  Array.Sort(retrievedLocations);

  // Assuming Array retrievedLocations has following Values:

  // New Jersey
  // New York
  // Wisconsin

    if (e.Item is GridEditableItem && e.Item.IsInEditMode)

    {
        GridEditableItem item = (GridEditableItem)e.Item;

        // Beginning of Loop each row in array retrievedLocations until no rows in array

        RadComboBox combo = (RadComboBox)item.FindControl("Address_LocationRadComboBox");

        foreach (RadComboBoxItem ComboItem in combo.Items)
        {
            if (ComboItem.Value != row value of array retrievedLocations)
            {
               ComboItem.Visible = false;
            }
            else
            {
               ComboItem.Visible = true;
            }

        }

       // End of Loop each row in array retrievedLocations until no rows in array

    }
}

Hi,

These are the following approaches to hide the ComboBox Item.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  string[] retrievedLocations = (string[])Session["LocationData"];
  Array.Sort(retrievedLocations);

    if (e.Item is GridEditableItem && e.Item.IsInEditMode)

    {
        GridEditableItem item = (GridEditableItem)e.Item;

        for (int i = 0; i < retrievedLocations.Length; i++)
        {
           RadComboBox combo = (RadComboBox)item.FindControl("Address_LocationRadComboBox");
           foreach (RadComboBoxItem ComboItem in combo.Items)
           {
               if (ComboItem.Value != retrievedLocations[i])
               {
                  ComboItem.Visible = false;
               }
               else
               {
                  ComboItem.Visible = true;
               }
            }
        }
    }
}

OR

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    string[] retrievedLocations = (string[])Session["LocationData"];
    Array.Sort(retrievedLocations);
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = (GridEditableItem)e.Item;
        RadComboBox combo = (RadComboBox)item.FindControl("Address_LocationRadComboBox");
        foreach (RadComboBoxItem ComboItem in combo.Items)
        {
            for (int i = 0; i < retrievedLocations.Length; i++)
            {

                 if (ComboItem.Value != retrievedLocations[i])
                 {
                    ComboItem.Visible = false;
                 }
                 else
                 {
                    ComboItem.Visible = true;
                 }

            }
        }
    }
}
