[ADVANCED-DOTNET] accessing a particular table in a dataset

[Aman Jain]

Hi All,

I have a xml as shown below

<Devices>
            <Device>
                        <DeviceId>0</DeviceId>
                        <Axes>
                                    <Axis>
                                                <Name>Robot Z</Name>
                                                <CS>0</CS>
                                                .
                                                .
                                                .
                                    </Axis>
                                    .
                                    .
                        <Axes>
            </Device>
            <Device>
                        <DeviceId>1</DeviceId>
                        <Axes>
                                    <Axis>
                                                <Name>Table X</Name>
                                                <CS>0</CS>
                                                .
                                                .
                                                .
                                    </Axis>
                                    .
                                    .
                        <Axes>
            </Device>

            <Device>
                        <DeviceId>2</DeviceId>
                        <Axes>
                                    <Axis>
                                                <Name>Table X</Name>
                                                <CS>0</CS>
                                                .
                                                .
                                                .
                                    </Axis>
                        <Axes>
            </Device>
</Devices>


I would like to display the "Axis" nodes in a data grid depending on the
DeviceId selected by the user.
I created a DataSet object and using its ReadXml method.

      myDataSet.ReadXml("MachineConfig.xml");
      //    datagridAxisInfo.DataSource = myDataSet; // works but shows
all axis nodes
      datagridAxisInfo.DataMember = "Axis";
      datagridAxisInfo.CaptionText = datagridAxisInfo.DataMember;


When I replaced the second line with

datagridAxisInfo.DataSource = myDataSet.Tables[0]

I get a error message saying that it cannot create a child list for
field axis.

How can I navigate to the Axis node for the particular device ?

Thanks in advance.

Regards

Aman
