Unresolved cell data binding after Q1-2012 release upgrade

[Paolo]

Hi hackers.

I recently upgraded to Q1-2012 libraries and all data columns in my grid seem to be empty, except for those having a custom CellTemplate defined.
Here's a code snippet: the first data column (Order ID) is correcty shown, all other columns are empty.

<telerik:RadGridView> 

                    x:Name="gridOrders"

                    Style="{StaticResource LOGridViewReadOnlyStyle}"

                    SelectionChanged="GridOrdersSelectionChanged"

                    HorizontalAlignment="Left" VerticalAlignment="Stretch"

                    BorderThickness="1,1,1,0"

                    FrozenColumnCount="5"

                    SelectionMode="Extended">

 

    <telerik:RadGridView.Columns>                  

 

        <!-- Order ID as Link -->

        <telerik:GridViewDataColumn Header="Order ID"

                                        DataMemberBinding="{Binding TaskId}"

                                        HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" Width="70"  >

            <telerik:GridViewDataColumn.CellTemplate>

                <DataTemplate>

                    <Button Content="{Binding TaskId}"

                            VerticalAlignment="Center"

                            HorizontalAlignment="Left"

                            Margin="0,0,0,0"

                            Style="{StaticResource HyperlinkButtonStyle}"

                            Foreground="{StaticResource HyperlinkButtonForegroundBrush}" />

                </DataTemplate>

            </telerik:GridViewDataColumn.CellTemplate>

        </telerik:GridViewDataColumn>

        <telerik:GridViewDataColumn Header="External ID1" DataMemberBinding="{Binding ExternalID1}" IsGroupable="False" IsFilterable="False" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" Width="100"  />

        <telerik:GridViewDataColumn Header="External ID2" DataMemberBinding="{Binding ExternalID2}" IsGroupable="False" IsFilterable="False" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" Width="100"  />

        <telerik:GridViewDataColumn Header="Internal Key" DataMemberBinding="{Binding DispKey}" IsGroupable="False" IsFilterable="False" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" Width="100"  />

        <telerik:GridViewDataColumn Header="Duration" DataMemberBinding="{Binding Duration, Converter={StaticResource DurationHourMinConverter}}" IsGroupable="False" IsFilterable="False" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}" Width="60" TextAlignment="Right" />

    </telerik:RadGridView.Columns>

</telerik:RadGridView>

What about breaking changes from previous releases?
Any suggestion to solve this issue?

Thanks in advance.

Hi,

We don't have any breaking changes related to columns/cells. What was your previous version? Can you send us an example where we can check working vs. non-working version of your scenario?

Hi Vlad,

thanks for your quick answer. My previous libraries version was 2011.2.0712.1040.
Finally, I found and solved the bug in my application's code and now GridView is working again: I'm filling an ObservableCollection from DB and assign it to the grid as ItemsSource... so, if I perform the assignment before retrieving data from the query, the grid is loaded with an empty source and cell binding is not resolved. Now, I moved the assignment after query response and everything works fine.

Thanks again.
Paolo
