I'm also wondering why there isn't a "SelectedValue" or a property like that to bind to. A bindable property would select the correct row via the FromKey method on the rows collection and retrieve the selected value via the selectedindex property. This isn't that hard to develop and would save us loads of work when binding in aspx.

Please enlighten us Infragistics :)

The answer is that Infrajistics does not support binding, this means that you can not use any infrajistics control inside of a control template. What's strange is that Infragistics does not even plan to include this in any future releses. Note my support response:

Thank you for submitting your query with Infragistics Developer Support via Chat.I have checked the issue in detail. The functionality for which you are looking for is not feasible. There is already a feature request submitted regarding this functionality with the following description:FR09509: Binding Support for WebCombo properties. However if you want this to be implemented in our future releases let me know so that I can create future suggestion on your behalf.Please let me know if I may close this case, or if you have further
questions regarding this case.Sincerely,

Hello Steve and All,

Indeed, it is a bit different from asp:dropdownlist, since the dropdown of the combobox is essentially grid with columns and SelectedValue needs to work in a different way.

Sorry for that, we will do our best to provide an easier declarative solution soon.

i'd like to say Im very dissapointed in this lack of feature.  please make every effort to make this available in a future relase.  i cant believe i have to use the standard asp.net dropdownlist when I just paid for these controls.

I agree. That is a serious drawback to what could be a very useful control.

We use Formviews extensively as they speed development, and we had made the assumption that the WebCombo would work with these since the much more primitive dropdown list does.

On the other hand, the dropdown in the UltraWebGrid doesn't bind to a SQLDatasource directly and yet a Webcombo does (and the lowly dropdown makes a lot more sense there).

Very odd.

Hi all.

I made a webusercontrol contains webcombo.Maybe It worked fine .But I don't know whether the correct.

sample vb code:

   private _value as object

   Public Property DataSourceID() As String Implements ICsBindControl.DataSourceID
        Get
            Return Me.WebCombo1.DataSourceID
        End Get
        Set(ByVal value As String)
            Me.WebCombo1.DataSourceID = value
        End Set
    End Property

    Public Property DataTextField() As String Implements ICsBindControl.DataTextField
        Get
            Return Me.WebCombo1.DataTextField
        End Get
        Set(ByVal value As String)
            Me.WebCombo1.DataTextField = value
        End Set
    End Property

    Public Property DataValueField() As String Implements ICsBindControl.DataValueField
        Get
            Return Me.WebCombo1.DataValueField
        End Get
        Set(ByVal value As String)
            Me.WebCombo1.DataValueField = value
        End Set
    End Property

    Public Property SelectedValue() As Object
        Get
            Return Me.WebCombo1.DataValue
        End Get
        Set(ByVal value As Object)
            Me.WebCombo1.DataValue = value

            Me._value = value

        End Set
    End Property

    Private Sub WebCombo1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles WebCombo1.DataBound
        If Me._value IsNot Nothing AndAlso (Me.WebCombo1.DataValue Is Nothing OrElse Me._value <> Me.WebCombo1.DataValue.ToString()) Then
            Me.WebCombo1.DataValue = Me._value
        End If
    End Sub

asp.net code:

<uc1:MyCombo ID="MyCombo1" runat="server" Selectedvalue='<%# Bind("FLD1") %>' DataSourceID="SqlDataSource1" DataValueField="KEYFLD1" DataTextField="NAMEFIELD1" ></uc1:MyCombo>
