GridViewDataColumn.DataMemberBinding with multiple sources

[Christophe]

Hello,

I need to create a GridView with a view model for each column (each column's view model is sharing with an another object).

This is my code behind:

...
for (int i = 0; i < max; i++)

{

    Binding MonBinding = new Binding("Points");

    MonBinding.Source = MonViewModel.CourbeTypeViewModels[i];

    MonBinding.Mode = BindingMode.OneWay;

 

    GridViewDataColumn GVDC = new GridViewDataColumn();

    GVDC.DataMemberBinding = MonBinding;

    GVDC.UniqueName = "ValCT" + i.ToString();

    GVDC.IsGroupable = false;

    GVDC.IsFilterable = false;

    GVDC.IsSortable = false;

    GVDC.IsReadOnly = true;

    Tableau.Columns.Add(GVDC);

}
...

My XAML :

...
<telerik:RadGridView Name="Tableau" AutoGenerateColumns="False" IsFilteringAllowed="False" ShowGroupPanel="False">

                <telerik:RadGridView.Columns/>

</telerik:RadGridView>
...

In child view model :

...

private ObservableCollection<decimal> _Points;

public ObservableCollection<decimal> Points

{

    get { return _Points; }

    set

    {

        _Points = value;

        OnPropertyChanged("Points");

    }

}
...

MonViewModel is my page view model (datacontext)
CourbeTypeViewModels is an ObservableCollection of CourbeTypeViewModel view model in MonViewModel
Points is an ObservableCollection<decimal> in each CourbeTypeViewModel
Tableau is a GridView in my page

This code creating 3 columns with header but without data...

My question : "How can I bind each column with it's own viewmodel ?"

Hi Christophe,

 

GridViewDataColumn is not designed to work in such scenarios. Why not use our ComboBoxColumn instead?
