Grid update

[Daniel]

Hello, 

I need to update te value of a cell in my radgrid view. When I try to change it the grid does not uptate its value until I reagroup or manipulate the grid in any other way

This is my code:

selectedItem = TryCast(Me.rgv_attributes.Items.Item(0), c_accionAtributo)
Me.rgv_attributes.Items.EditItem(selectedItem)
selectedItem.Value = "algo"
Me.rgv_attributes.Items.CommitEdit()

The itemsource is an ObservableCollection(Of c_accionAtributo) 
Me.rgv_attributes.ItemsSource = atributes


Any help?

Thanks!

Hello,

I have tested the code snippet you shared and both the values in the row and the group row were updated. Would you please share how have you configured your RadGridView?

Here is my code:

<telerik:RadGridView Margin="12" Name="rgv_attributes" ColumnWidth="*" AutoGenerateColumns="False" IsSynchronizedWithCurrentItem="True" CellEditEnded="rgv_attributes_CellEditEnded">
</telerik:RadGridView>

            Dim typeColumn As New GridViewDataColumn()
            typeColumn.DataMemberBinding = New System.Windows.Data.Binding("Type")
            rgv_attributes.Columns.Add(typeColumn)


            Dim valueColumn As New GridViewDataColumn()
            valueColumn.DataMemberBinding = New System.Windows.Data.Binding("Value")
            rgv_attributes.Columns.Add(valueColumn)

            Dim comboColumn As New GridViewComboBoxColumn()
            comboColumn.DataMemberBinding = New System.Windows.Data.Binding("Action")
            comboColumn.ItemsSource = AvailableGenders
            comboColumn.Width = 100

            rgv_attributes.Columns.Add(comboColumn)



            Me.rgv_attributes.ItemsSource = atributes


            Me.rgv_attributes.GroupDescriptors.Add(New ColumnGroupDescriptor() With { _
 .Column = Me.rgv_attributes.Columns("Type"), _
 .SortDirection = System.ComponentModel.ListSortDirection.Descending _
})

Thanks

Hello,

Any idea of why is this happening?

Hello,

Thank you for sharing that additional information.

Unfortunately I am still not able to reproduce an issue. This would happen if you have set Asynchronous DataLoadMode, but this is not your case.
Would it be possible for you to isolate the issue in a demo project and send it to me? You can open a support ticket and attach the solution there.

Hi again, 

I've just submitted a ticket  ID : 724100

Thanks!

Hi,

Thank you.

I am posting my answer here as well:

The reason why the data is not updated is that your class (c_accionAtributo) does not implement the INotifyPropertyChanged interface. 

You can check this msdn article for a reference on how to implement it.
