Hello Mario,

Make sure that you set AutoPostBack as true in order to fire OnSelectedIndexChanged event.

aspx:

<telerik:RadComboBox ID="rdFormatoAbertoComprimento" runat="server" AutoPostBack="true" OnSelectedIndex="rdFormatoAbertoComprimento_OnSelectedIndexChanged">
</telerik:RadComboBox>

Thanks,
Princy.

Hello Mário,

Your OnSelectedIndexChanged handler naming is incorrect, should be as follows:

<telerik:RadComboBox ID="rdFormatoAbertoComprimento" runat="server"
                EnableEmbeddedSkins="false"

Skin="GraphControl" Width="160" DropDownWidth="150" EnableLoadOnDemand="True"

Height="200" AutoPostBack=true

OnItemsRequested="rdFormatoAbertoComprimento_OnItemsRequested"

OnSelectedIndexChanged="rdFormatoAbertoComprimento_OnSelectedIndexChanged"

OnDataBinding="rdFormatoAbertoComprimento_OnDataBinding"

EnablePostBackOnRowClick="true">

</telerik:RadComboBox>
