Hi NICK, 

Thanks For the kind help. 

I tried the above mentioned solution but not able to get results. So now i have used cell value presenter to display the table inside a table.

private void onPropertyChanged(object sender, string propertyName)

}

But the new problem is that it is showing same  table inside that cell. But i want to bind only particular value to that cell? 

I tried to use the

 <igDP:XamDataGrid  DataSource="{Binding Path=ViewSetList.Parameters.VALUE, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MainWindow}} }" />

But It is showing empty.  Please help?

Hi Nick, 

Thanks For the reply. But it is not theme issue.

I am attaching the Project. I am using Data Trigger to check the value of the variable : "IsTableData". If it is "true"  Then the Field "VALUE" should display the table inside the cell. But it is not displaying the Table. Instead it is just printing the value.

i have tried to represent  my problem in the attached project. Please help me to display the table inside the Field. If the value of the IstableData = True

Hi Nick,

Any update on this ?

Thanks

Hello AKshay,

Thank you for the sample you have sent. It was very helpful to observe the functionality you want to achieve.

In order to display the table inside the Field if the value of the IstableData = True, you will have to use a different binding for the Data Trigger. For example:

<DataTrigger Binding="{Binding Path=DataItem.IsTableData}"  Value="True">

As in the previous examples it depends on the Context you are currently using and the binding. The cell wraps the values from the data source for an associated Field for a specific DataRecord. It is represented in the UI by corresponding CellValuePresenter. Each DataRecord has a DataItem which in your scenario is Parameters.

Hi Nick,

Thanks for the clarification. 

I have changed the code based on your suggestion.

<Style TargetType="{x:Type igDP:CellValuePresenter}" x:Key="TableData">
<Style.Triggers>

<DataTrigger Binding="{Binding Path=DataItem.IsTableData}" Value="True">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<!--<ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">-->
<igDP:XamDataGrid DataSource="{Binding Path = ViewSetList/TableData, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MainWindow}} }" />
<!--</ControlTemplate>-->
</DataTemplate>
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>

But still seeing same  blank field

Thanks Nick. It was a binding issue. I managed to get the table inside a table.

I have couple of questions here.

1. Why you have used Data ParameterList/tableData. Cant we use ParameterList.Tabledata for binding?

2. Is there any good source to learn WPF complex bindings other then MSDN.

Thanks

Akshay

Hello AKshay,

I have modified the sample you have sent and added the functionality we discussed. When I run the project there are two XamDataGrids, and the child is populated with DataTable as you can see in the screenshot from my previous post.

Please test this project on your PC; whether or not it works correctly may help indicate the nature of this issue.

If the project does show the XamDataGrid populated, this indicates that something in your application prevents the DataTable to be displayed (e.g. styles, data binding, etc.).

If the project does not work correctly, this indicates either a problem possibly specific to your environment, or a difference in the DLL versions we are using.  My test was performed using version 17.1.20171.2073.

Hi Nick,

 i tried your Suggestion but no table is populated. So i decided to convert Data table to string. and just show the string inside that parent table. 

i.e Parameter VALUE = convertDataTableToString(Datatable);  //this function will convert data table to string with rows and columns 

During the debugging the i checked the Value it is showing like IMAGE 1

and final output is like this

Will Xamdatagrid will remove the spaces from the string?

Hello AKshay,

Thank you for the image you have sent,

You referred in your last post to field VALUE. If you look at it there is a scrollbar which was activated because the XamDataGrid is too small.
You will be able to view the XamDataGrid if you increase the CellHeight, for example:

<igDP:XamDataGrid  DataSource="{Binding  ViewSetList,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MainWindow}} }" >
                        <igDP:XamDataGrid.FieldSettings>
                            <igDP:FieldSettings CellHeight="100"/>
                        </igDP:XamDataGrid.FieldSettings>
