Radcombobox in EditItemTemplate column - Selection out of range

[Amirtha S]

Hi
I am making use of a Radcombobox inside a Radgrid during Edit mode. I get this problem when I have different values for the
DataValueField and DataTextField. When I make use of the same valeus for both, I don't get the error and the Radcombobox is geting populated.

 

<telerik:RadComboBox ID="CbAircraftModelType" runat="server" Skin="Black"
                            SelectedValue='<%# Bind("modelTypeName") %>' EmptyMessage=" Select Aircraft Type"
                            HighlightTemplatedItems="True" DataTextField="modelTypeName" DataValueField="modelTypeId"
                            EnableTextSelection="False" DataSourceID="SqlDataSource_AircraftType"
                            OnClientSelectedIndexChanged="cb_OnClientSelectedIndexChanged" />

I am making use of a SqlDataSource to populate the Radcombobox.

<asp:SqlDataSource ID="SqlDataSource_AircraftType" runat="server"
                    ConnectionString="<%$ ConnectionStrings:AvengeConnectionString %>"
                 SelectCommand="select modelTypeName,modelTypeId from Avenge.dbo.AircraftModelType ">
            </asp:SqlDataSource>

I don't have any code for working with this in the code-behind.

This is the error that I am getting:

Selection out of range

Hope someone will be able to help me with this.

Thanks.

Hi Amirtha,
You are setting the SelectedValue to <%# Bind("modelTypeName") %> however you are binding the value column to DataValueField="modelTypeId" so the combo box is looking for modelTypeName, in the ID column which will not exist.  You need to bind the selectedValue to the modelTypeID to make the code you posted work as expected. 

I hope this helps :)

Thanks!

Hi Amirtha,

I have a same problem but in insert mode. When I like insert a new record I get the error System.ArgumentOutOfRangeException: Selection out of range.

<

 

radG:GridTemplateColumn DataField="idTblOpciones" DataType="System.Int32" HeaderText="Tipo Intervencion"

 

 

UniqueName="idTblOpciones">

 

 

<EditItemTemplate>

 

 

<radC:RadComboBox ID="idTblOpcionesDwn" runat="server" DataSourceID="SqlDataSourceTiposIntervencion"

 

 

DataTextField="NombreOpcion" DataValueField="idTblOpciones" Skin="Office2007"

 

 

SelectedValue="<%# Bind('idTblOpciones') %>"

 

 

SkinsPath="~/RadControls/ComboBox/Skins" Width="150px">

 

 

</radC:RadComboBox>

 

 

</EditItemTemplate>

 

 

<ItemTemplate>

 

 

<asp:Label ID="idTblOpcionesLabel" runat="server" Text='<%# Eval("idTblOpciones") %>'></asp:Label>

 

 

</ItemTemplate>

 

 

</radG:GridTemplateColumn>

 

I am using sqlDataSource to populated the radComboBox:

<

 

asp:SqlDataSource ID="SqlDataSourceTiposIntervencion" runat="server" ConnectionString="<%$ ConnectionStrings:VIGIAConnectionString %>"

 

 

SelectCommand="spGetTblOpcionesbyLista" SelectCommandType="StoredProcedure">

 

 

<SelectParameters>

 

 

<asp:Parameter DefaultValue="240" Name="idTblListas" Type="Int32" />

 

 

</SelectParameters>

 

 

</asp:SqlDataSource>

 

Can you help me to resolved this error?

thanks,

Julio P

Hello Julio Paez,

This happens because there is no value in the idTblOpciones column in the DataItem of the Grid Item in Insert Mode (you are about to choose that data on insertion). The RadComboBox tries to select the empty string and it fails because probably all Items have values.

You can either add a default Item (Value="") inline and set the AppendDataBoundItems to true on the RCB, add the same Item directly in the data source or remove the Bind expression and manually supply the selected value of the RCB in the Inserting event of the data source.

An example of the first approach:

<telerik:RadComboBox ID="RadComboBox1" runat="server" AppendDataBoundItems="true" ...>
    <Items>
        <telerik:RadComboBoxItem Text="Choose a Value" Value="" />
    </Items>
</telerik:RadComboBox>

Sincerely yours,
Simon
