Own message for checked items

[Peter]

Hi, 

I use following combobox

<telerik:RadComboBox ID="rcbDaysOfWeek" runat="server" Width="150px"
    CheckBoxes="true" EnableCheckAllItemsCheckBox="true"
    EmptyMessage="No day selected">
    <Localization AllItemsCheckedString="All days" CheckAllString="Select all"  />
    <Items>
        <telerik:RadComboBoxItem Text="Monday" Value="1" Checked="true" />
        <telerik:RadComboBoxItem Text="Tuesday" Value="2" Checked="true" />
        <telerik:RadComboBoxItem Text="Wednesday" Value="3" Checked="true" />
        <telerik:RadComboBoxItem Text="Thursday" Value="4" Checked="true" />
        <telerik:RadComboBoxItem Text="Friday" Value="5" Checked="true" />
        <telerik:RadComboBoxItem Text="Saturday" Value="6" Checked="true" />
        <telerik:RadComboBoxItem Text="Sunday" Value="7" Checked="true" />
    </Items>
</telerik:RadComboBox>

Could you advice me how can I manage to have my custom message if I select 4 days - I want to have "1347" instead of "4 items checked". I want to have values of those selected checkboxed written in the message... 

Thanks a lot...

Hi,

I am afraid that changing the text in RadComboBox when you use CheckBoxes is not supported.
The CheckBoxes feature sets the text in the control internally by design.
You can obtain the values of the checked items via CheckedItems collection:

<telerik:RadComboBox ID="rcbDaysOfWeek" runat="server" Width="150px"
    CheckBoxes="true" EnableCheckAllItemsCheckBox="true"
    AutoPostBack="true" OnItemChecked="rcbDaysOfWeek_ItemChecked"
    EmptyMessage="No day selected">
    <Localization  AllItemsCheckedString="All days" CheckAllString="Select all"  />
    <Items>
        <telerik:RadComboBoxItem Text="Monday" Value="1" Checked="true" />
        <telerik:RadComboBoxItem Text="Tuesday" Value="2" Checked="true" />
        <telerik:RadComboBoxItem Text="Wednesday" Value="3" Checked="true" />
        <telerik:RadComboBoxItem Text="Thursday" Value="4" Checked="true" />
        <telerik:RadComboBoxItem Text="Friday" Value="5" Checked="true" />
        <telerik:RadComboBoxItem Text="Saturday" Value="6" Checked="true" />
        <telerik:RadComboBoxItem Text="Sunday" Value="7" Checked="true" />
    </Items>
</telerik:RadComboBox>
<asp:Label ID="lblValues" runat="server" ></asp:Label>

protected void rcbDaysOfWeek_ItemChecked(object sender, Telerik.Web.UI.RadComboBoxItemEventArgs e)
{
    lblValues.Text = "Checked items values: ";
    foreach(RadComboBoxItem item in rcbDaysOfWeek.CheckedItems)
        lblValues.Text += item.Value + " ";
}

All the best,
