Hi,

This sample for dictionary binding to xamDataTree is not available anymore ,  can you please attach any sample code or file for same .

Thank you in advance

Hi jlmehta,

I have reviewed your code and after further investigation it turned out that if you inherit Dictionary<String, String> in another class, for example InheritedDictionary and use that class and place it in the TargetTypeName it would show the keys or the values of the Dictionary according to the DisplayMemeberPath that you want to see. The other thing is that the Key for the NodeLayout that is going to display the nodes from the dictionary should be equal to the name of the property of that dictionary. I hope that helps you!

To the second question, i don't think it is possible to not have nodes that are not visible, because they don't have children, but i need to double check that and confirm that later.

Regards,

Nikola.

 

Any suggestions on this?

Thanks..

Thanks for your example Nikola, but I'm afraid thats not what I'm looking for exactly. Here's roughtly the structure of a tree I want.

Object A has a list of Object B.

Object B has a list of Object C.

Object C has a Dictionary<String, String>

I bind the tree to A.List<B> (List of B is Object A)

I want the tree to look something like this

B1
---C11
---C12
------Dictionary key1
------Dictionary key1
---C13
------Dictionary key1
B2
---C21
------Dictionary key1
------Dictionary key1
---C22

The code I ahve right now is

<ig:XamDataTree ItemsSource="{Binding InnerReport.ReportColumns}">
            <ig:XamDataTree.GlobalNodeLayouts>
                <ig:NodeLayout Key="ColLayout" TargetTypeName="ReportColumn" DisplayMemberPath="DisplayName"/>
                <ig:NodeLayout Key="DrlDnLayout"
                     TargetTypeName="ReportDrillDown" DisplayMemberPath="ContextMenulabel">
                    <ig:NodeLayout.CheckBoxSettings>
                        <ig:CheckBoxSettingsOverride CheckBoxVisibility="Visible" />
                    </ig:NodeLayout.CheckBoxSettings>
                </ig:NodeLayout>
                <ig:NodeLayout Key="MapLayout" TargetTypeName="Dictionary&lt;string,string>" DisplayMemberPath="Key"/>
            </ig:XamDataTree.GlobalNodeLayouts>
        </ig:XamDataTree>

           
           
            The model objects used are set up like this, InnerReport has a ReportColumns property which is a List<ReportColumn>
            ReportColumn has DrilldownList property which is a List<ReportDrilldown>
            ReportDrilldown has a Mapping property which is a Dictionary<string,string>
           
            Hope i was able to explain it properly. How should I now set up the dictionary in the NodeLayout?

 

Also on a related topic, is it possible for the tree to not show Nodes which have no children? So in the Above example, the tree would not show ReportColumn if its List<ReportDrilldown> is empty.

Thanks
