Hi All,
How can i make a null item to represent null values for a combobox in a formview?
in a details view it might look like this:
Can i add an empty list item in a similar way in design view for combobox? also.. is there a convertEmptyStringToNull equivalent in formsview (i know not telerik related..) thanks.

SortExpression="currencyID">
<EditItemTemplate>
<asp:DropDownList ID="DdlCurrencyEdit" runat="server"
AppendDataBoundItems="true" DataSourceID="SqlDSCurrencies"
DataTextField="currencyName" DataValueField="currencyID"
SelectedValue='<%# Bind("currencyID") %>'>
<asp:ListItem Value="">(none)</asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>
Can i add an empty list item in a similar way in design view for combobox? also.. is there a convertEmptyStringToNull equivalent in formsview (i know not telerik related..) thanks.

Hello Rich,
I am not exactly sure what do you mean by null items in RadComboBox?
You can add an item with empty Text and Value properties, is that null item for you?
You can add it from the designer just like you add any other combo item.

Hi,
To clarify i would like to have an item in the ComboBox that represents an empty/null value. These comboboxes are databound and i was wondering if there was a way in design view to set up an empty item rather than in code-behind. This way when it is bound and there is no value the "blank" item will be selected.
So basically can i add an empty item to a databound combobox in design view.

Hi Rich,
Yes, you can.
Just make sure you have set the AppendDataBoundItems to True so both the bound and unbound items are shown in the combobox.
