Hi,

i have one combobox i.e.

 <telerik:RadComboBox ID="Fund" runat="server"
                            DataSourceID="Source" DataTextField="Code" DataValueField="Currency" 
                            Width="55px" Skin="Outlook" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged1" SelectedValue='<%# Bind("Fund") %>'
                            BorderWidth="1px">
                       </telerik:RadComboBox> 

now the dropdown is populating with 3 values on page load.e.g 1 , 2 and 3
whenever i am selecting 1 and 2 it is ok but when selecting 3 it automatically takes 1.
strange problem but i dont have any clue why this is happening.
but if  replace DataValueField = "currency" with DataValueField="code" then it is working absolutely fine.

please help me as i dont have any clue why it is behaving like so.

waiting for reply.

thanks in advance.

Hi bharat kumar,

I can not see the DataSource to which you are binding the RadComboBox. However I guess the "currency " DataValueField is not with unique values. Please take a look at this help topic about RadComboBox selecting a different item

Hope this helps.

All the best,

thank you very much.
yes you are right and the value field do not have unique values.

but is it possible to have two value field or something by which this problem is handled.
otherwise i have to change the code and do some work around.

Hi bharat kumar,

Try using the CurrencyID instead of it's name in the DataValueField. Of course you should check if your Id-s are unique.

Hope this helps.
