Hi Bernard,

     Thanks for your reply.

Below is some of my code sample:

The AdditionalSearchFields="" is working fine, but got error if i change it to AdditionalSearchFields="Name".

My webcomb code:

                        <ISWebCombo:WebCombo ID="wCombo1" runat="server" DataTextField="Code" DataValueField="ID" Height="22px " Width="200px" DropDownRows="20" AdditionalSearchFields="Name" AllowWildCardSearch = "True" DataMember="" AllowAutoPostback="True" BindingOperationMode="ClientBinding" UseDefaultStyle="True"> <Columns>

                            <ISWebCombo:WebComboColumn BaseFieldName="Code" HeaderText="Code" Name="Code"  width = "50"  />

                            <ISWebCombo:WebComboColumn BaseFieldName="Name" HeaderText="Name" Name="Name"  width = "50"  />

                            <ISWebCombo:WebComboColumn BaseFieldName="RefCode" HeaderText="R. Code" Name="R. Code"  width = "50"  />

                            <ISWebCombo:WebComboColumn BaseFieldName="Addr1" HeaderText="Addr1" Name="Addr1"  width = "200"  />

                            <ISWebCombo:WebComboColumn BaseFieldName="Remark" HeaderText="Remark" Name="Remark"  width = "200"  />

                            </Columns>

                            <LayoutSettings ComboMode="MultipleColumns" SearchIconMode="Graphic" SearchImage="Search_XPBlue.gif"><HeaderStyle BackColor="#4D6185" Font-Names="segoe ui,tahoma" Font-Size="8pt" ForeColor="White" BackColor2="199, 223, 255" GradientType="Vertical" Height="20px"><Padding Bottom="3px" Left="3px" Right="3px" Top="3px" /><BorderSettings > <Bottom Color="101,147,207" Style="solid" Width="1px" /><Right Color="AliceBlue" Style="solid" Width="1px" /></BorderSettings></HeaderStyle><DropDownStyle><Active BaseStyle="Over" BackgroundImage="url(/CommonLibrary/Images/DD4_Active.gif)" ></Active><Over BaseStyle="Normal" BackgroundImage="url(/CommonLibrary/Images/Vis_DDActive.gif)" ForeColor="#6C8DC7" CustomRules="filter: Alpha(opacity=100)"><BorderSettings><Left Color="40, 106, 155" Style="Solid" Width="1px" /></BorderSettings></Over><Normal Cursor="Hand" Font-Names="Arial" Font-Size="0pt" ForeColor="White" Height="20px" Width="16px" BackgroundImage = "url(/CommonLibrary/Images/Vis_DDNormal.gif)" CustomRules="background-repeat:no-repeat"><Padding Bottom="2px" Left="0px" Right="1px" Top="0px" /></Normal></DropDownStyle><TextBoxStyle><Active BaseStyle="Over"></Active><Over BaseStyle="Normal"></Over><Normal BackColor="Transparent" BorderStyle="None" BorderWidth="0px" CustomRules="background:transparent;background:transparent;background:transparent;background:transparent" Font-Names="segoe ui,tahoma" Font-Size="8pt" ForeColor="Black" Height="20px" Width="180px"></Normal></TextBoxStyle><ResultFrameStyle BackColor="White" BorderColor="Black" BorderStyle="Solid" BorderWidth="1px"></ResultFrameStyle><ColumnStyle CustomRules="text-overflow:ellipsis" Overflow="Hidden" OverflowX="Hidden" OverflowY="Hidden"><Padding Left="3px" Right="3px" /></ColumnStyle><FrameStyle><Active BaseStyle="Over" BackColor="WhiteSmoke"></Active><Over BaseStyle="Normal" BackColor="WhiteSmoke" BorderColor="#4D6185"></Over><Normal BackColor="White" BorderColor="Gray" BorderStyle="Solid" BorderWidth="1px" Height="20px" Width="200px"></Normal></FrameStyle><MoreButtonStyle><Active BaseStyle="Over"></Active><Over BackColor="#E9EBF4" BaseStyle="Normal" BorderColor="Silver"></Over><Normal BorderColor="White" BorderStyle="Solid" BorderWidth="1px"></Normal></MoreButtonStyle><StatusBoxStyle BackColor="#4D6185" Font-Names="segoe ui,tahoma" Font-Size="8pt" ForeColor="White"></StatusBoxStyle><ResultBoxStyle Font-Names="segoe ui,tahoma" Font-Size="8pt"></ResultBoxStyle><RowStyle><Over BackColor="WhiteSmoke" BaseStyle="Normal"></Over><Normal BackColor="White" Height="20px"></Normal></RowStyle><SelectedRowStyle BackColor="#404040" Font-Names="Verdana" Font-Size="8pt" ForeColor="White" Height="20px" /></LayoutSettings>

                            <ClientBindingSettings DataSourceType="WebService" ServiceUrl="http://localhost:1406/WanTech_WebService/WTService.asmx">

                                <ServiceMethods SelectMethod="GetWClient" /></ClientBindingSettings>

                        </ISWebCombo:WebCombo>

My webservice code:

    <WebMethod> _

    Public Function GetWClient(ByVal selectArguments As ISNet.ClientServices.DataSourceSelectArguments) As QueryResult

        Try

            Dim context As dcWanTechDataContext = New dcWanTechDataContext

            Dim query As WebComboDataProvider(Of tbFil_Client) = New WebComboDataProvider(Of tbFil_Client)(context.tbFil_Client)

           Return query.Select(selectArguments)

        Catch ex As Exception

            MsgBox(ex.Message)

        End Try

    End Function

Hi Yogoo,

I can replicate your issue in our local end. Unfortunately, when using WebService, you could use AdditionalSearchFields property inside WebCombo but you should filter the data inside WebService. You can input the filter expression in DataSourceSelectArguments. Here's the example:

[WebMethod]
public QueryResult GetCustomers(DataSourceSelectArguments selectArguments)
{
    NorthwindDataContext context = new NorthwindDataContext();
    context.DeferredLoadingEnabled = false;
    context.ObjectTrackingEnabled = false;
    string param;
    if(selectArguments.FilterExpression.Contains("like"))
    {
        param = selectArguments.FilterExpression.Split('\'')[1];
        selectArguments.FilterExpression = "([ContactName] like '" + param + "' or [Address] like '" + param + "')";
    }
    WebComboDataProvider<Customer> query =
        new WebComboDataProvider<Customer>(context.Customers);
    return query.Select(selectArguments);
}

Using that expression, I persist WebCombo to filter the value using ContactName and Address regarding the input that you put inside WebCombo. Please let me know if this matter still happen in your local end. I'll gladly help you to resolve it. Hope this helps.

Bernard

OK thanks, I found that the FilterExpression value has been changed from "[Name]" to "[0]", That the error come from. I just replace the [0] to [Name] and it's working fine.

Hi Yogoo,

Glad that you have found your problem. If you have any further question, please don't hesitate to ask us.

Bernard
