[Solved] Define Columns in Xaml for a Derived RadGridView

[Jean Paul Mir V.]

Hi,

I'm trying to create a Custom GridView by inheriting RadGridView and adding some specific functionality. So far, the custom control definition is plain basic:

Imports Telerik.Windows.Controls
Imports System.ComponentModel

Public Class MCPaginatedGridView
    Inherits RadGridView
End Class

This usercontrol is inside of a user control library referenced across all Prism modules in a big solution.
When I'm trying to instantiate this control in a different assembly like this:

<MCControls:MCPaginatedGridView Grid.Row="12"
                                Grid.Column="0"
                                Grid.ColumnSpan="5"
                                FontSize="10"
                                MinHeight="250"
                                AutoGenerateColumns="False">
    <MCControls:MCPaginatedGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding LoteCobranzaDetalleId}" Header="ID" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding NumeroContrato}" Header="Contrato" UniqueName="NumeroContrato" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding CedulaDomiciliatario}" Header="Cedula" UniqueName="CedulaDomiciliatario" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding NombreDomiciliatario}" Header="Nombre" UniqueName="NombreDomiciliatario" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding FechaValor, Mode=TwoWay}" DataFormatString="{}{0:d}" Header="Fecha Valor" UniqueName="FechaValor" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding FechaVencimiento, Mode=TwoWay}" DataFormatString="{}{0:d}" Header="Fecha Venc." UniqueName="FechaVencimiento" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding SaldoCuota, Mode=TwoWay}" Header="Monto" DataFormatString="{}{0:c}" UniqueName="Saldo" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding MontoPendientePorProcesar, Mode=TwoWay}" DataFormatString="{}{0:c}" Header="Pendiente" UniqueName="MontoPendientePorProcesar" />
    </MCControls:MCPaginatedGridView.Columns>
</MCControls:MCPaginatedGridView>

... an exception is thrown by the Xaml Editor indicating that: "The property 'MCControls:MCPaginatedGridView.Columns' is not declared as attached property"

Could you please provide any help on this?

Thanks in advance

Hello,

 Do you have all needed references added to this project? You can check the grid assemblies here:

Hi Vlad,

Thanks for your answer!
Yes, I have all these references in both projects: The controls library and the prism module (Here copyLocal=False).
In fact, I've used telerik in other cases directly (not deriving it) and it works fine...

Any Ideas?
