[Solved] GridComboBox don´t display DropDownList

[Nelson]

Hi,

I use in my code a GridComboBox but i can´t make that it display the dropDownList.

I have this :

<telerik:RadGridView.Columns>
                   <telerik:GridViewDataColumn DataMemberBinding="{Binding EntidadesProp.TiposentidadeProp.DesignacaoProp}" Header="Tipo Entidade" Width="0.15*"/>
                   <telerik:GridViewDataColumn DataMemberBinding="{Binding EntidadesProp.TitulosProp.AbreviaturaProp}" Header="Título" Width="0.15*"/>
                   <telerik:GridViewDataColumn DataMemberBinding="{Binding EntidadesProp.NomeTratamentoProp}" Header="Nome" Width="0.6*"/>
                   <telerik:GridViewComboBoxColumn
                   DataMemberBinding="{Binding IdProp}"
                   SelectedValueMemberPath="Função"
                   DisplayMemberPath="DesignacaoProp"
                   ItemsSource="{Binding OCFuncoesReuniao,Source={StaticResource ConvocadosVM}}"/>

Please look at the picture to see the result.

Thanks in advance.

Hi Nelson,

Everything seems correct on the provided xaml code and based only on it I am not able to see the cause of the issue. May you verify if the IdProp property is available ? Is it a nested property to another object (as those in the first columns) ?

Hi Maya thanks for the quick reply.

I really don´t know why don´t work. my GridViewComboBoxColumn have a different collection of the first columns.

And yes, the IdProp property is available...

Hi Nelson,

Unfortunately, I am not able to suggest any further without additional information. I may suggest you to run through our online documentation and demos for a reference on how to implement GridViewComboBoxColumn. 
Generally, it would be great if you could send us a sample project that illustrates the issue or at least provide some additional relevant code-snippets.
