Issue with xamGrid and VS 2010
posted

Hi everyone,

I have an issue with xamGrid and VS2010. I've tried to define self-referenced hierarchy with hierarchical layout. It should look like this:

1. Group 1

    1.1. Subgroup 2

         1.1.1. Element 1

         1.1.2. Element 2

    1.2. Subgroup 2

         1.2.1. Element 1

2. Group 2

    2.1. Subgroup 3

         2.1.1. Element 3

         2.1.2. Element 4

    2.2. Subgroup 4

         2.2.1. Element 5

 

I've solved this part with Groups and Subgroups:

<ig:XamGrid Name="xamGrid1" AutoGenerateColumns="False" Grid.Column="1" ItemsSource="{Binding Path=FilteredActivityGroups}">

            <ig:XamGrid.ColumnLayouts>

                <ig:ColumnLayout Key="Subgroups" TargetTypeName="ActivityGroup">

                    <ig:ColumnLayout.Columns>

                        <ig:TextColumn Key="IDActivityGroup" />

                        <ig:TextColumn Key="GroupTerm" />

                        <ig:TextColumn Key="IDSuperGroup" />

                        <ig:TextColumn Key="Template" />                     

                    </ig:ColumnLayout.Columns>

                </ig:ColumnLayout>

            </ig:XamGrid.ColumnLayouts>

        </ig:XamGrid>        

 

And it works. Then I tried to add elements (activities in this case):

<ig:XamGrid Name="xamGrid1" AutoGenerateColumns="False" Grid.Column="1" ItemsSource="{Binding Path=FilteredActivityGroups}">            

            <ig:XamGrid.ColumnLayouts>

                <ig:ColumnLayout Key="Subgroups" TargetTypeName="ActivityGroup">

                    <ig:ColumnLayout.Columns>

                        <ig:TextColumn Key="IDActivityGroup" />

                        <ig:TextColumn Key="GroupTerm" />

                        <ig:TextColumn Key="IDSuperGroup" />

                        <ig:TextColumn Key="Template" />

                        <ig:ColumnLayout Key="Activities">

                            <ig:ColumnLayout.Columns>

                                <ig:TextColumn Key="IDActivity" />

                                <ig:TextColumn Key="ActivityTerm" />

                                <ig:TextColumn Key="ActivityTemplate" />

                                <ig:TextColumn Key="IDActivityGroup" />                           

                            </ig:ColumnLayout.Columns>

                        </ig:ColumnLayout>

                    </ig:ColumnLayout.Columns>

                </ig:ColumnLayout>             

            </ig:XamGrid.ColumnLayouts>

        </ig:XamGrid>        

 

This way, my VS2010 crashes with no message. All I have is "Not responding", and then crashes. When I comment this part:

                                <ig:TextColumn Key="IDActivity" />

                                <ig:TextColumn Key="ActivityTerm" />

                                <ig:TextColumn Key="ActivityTemplate" />

                                <ig:TextColumn Key="IDActivityGroup" /> 

 

I see my grid, and area where activities should be displayed, but with no data.

I've found post similar to this, could it be problem with collection? I've attached classes which I use for this hierarchy.

I need this kind of hierarchy, but it doesn't have to be this way. If it is possible with xamDataTree, or any other control, I would be happy to know. I'll accept any good advice.

 

Thank you.
