Hi,

When i select a particular item in the listbox, i want to check for a condition and display a message to the user. I could display a message but the item is not displaying in the destination listbox. Why are the selected items not displaying in destination list box?

C# code:

protected void rlbClntService_Transferring(object sender, RadListBoxTransferringEventArgs e)

{

string hHold = Uc_Client.Clients.SelectedValue;

double pLevel, eligibility;

string sItem;

pLevel = objBLLClntServ.GetClientPLevel(hHold);

sItem = rlbClntService.SelectedItem.Value;

eligibility = objBLLClntServ.GetEForSelectedItem(sItem);

if (pLevel > eligibility)

{

//ScriptManager.RegisterStartupScript(this, GetType(), "showalert", "alert('Client is not eligible.');", true);

lblWarning.Text = "This client not eligible. ";

mpuWarning.Show();

}

ASPX:

<table>

<tr>

<td>

<telerik:RadListBox ID="rlbClntService" runat="server" AllowTransfer="True" AllowTransferDuplicates="false" AutoPostBack="true"

AllowTransferOnDoubleClick="True" AutoPostBackOnTransfer="true" EnableDragAndDrop="true"

Height="130px" Skin="Forest" TransferToID="rlbSelectedServices" Width="400px" OnTransferring="rlbClntService_Transferring">

<ButtonSettings ShowReorder="false" ShowTransferAll="false" />

</telerik:RadListBox>

</td>

<td>

<table>

<tr>

<td>

<asp:Label ID="lblSelectedServices" runat="server" CssClass="label" Text="Selected Services" />

</td>

</tr>

<tr>

<td>

<telerik:RadListBox ID="rlbSelectedServices" runat="server" AllowDelete="true" Height="110px"

Skin="Forest" Width="400px">

<ButtonSettings ShowDelete="true" TransferButtons="All" />

</telerik:RadListBox>

</td>

</tr>

</table>

</td>

</tr>

</table>
