I don't know if there is a neat way of displaying the code, or at least I don't know where to host it.  I say that because I believe part of the problem I'm having is how the data is presented to the grid.  The data is coming from a json ServiceStack call, See below:

<table id="hierarchicalGrid"></table>

    <script type="text/javascript">

        var data = @UserInformation.AsRawJson()

        $("#hierarchicalGrid").igHierarchicalGrid({

            datasourcetype: 'json',

            dataSource: data,

            odata: true,

            initialDataBindDepth: 0,

            autoGenerateLayouts: false,

            autoGenerateColumns: false,

            columns:

               [{ key: "Username", dataType: "string", headerText: "Username" },

                { key: "EmplID", dataType: "string", headerText: "EmplID"  },

                { key: "Comment", dataType: "string", headerText: "Comment" }],

            columnLayouts: [

                    {

                        key: "GroupInformation",

                        childrenDataProperty: "GroupInformation",

                        autoGenerateLayouts: false,

                        columnLayouts: 

                            [{  key: "GroupName",

                                autoGenerateColumns: true}]

                    }]

        });

    </script>

That is what my code looks like in its current format.  Running this code gives me exactly what I want on the parent band.  The child band errors out with the message:

"Microsoft JScript runtime error: Unable to get value of the property 'dataType': object is null or undefined"

The data is now give to the grid as rawjson is from a list from a class that has fields "UserName, EmplID, Comment, and a property as a list that has fields "GroupName and GroupDescription" for my child band which will have multiple rows per one row of parent band.  The name of the list that holds the child band information is "mygroup"

Hello Jason,

Binding igHierarchicalGrid to flat data source is not possible. For this purpose you should use igTreeGrid control instead.

Looking at your last response I see couple of things that need to be changed in the igHierarchicalGrid configuration:

1.The error you get is because you didn't define a "primaryKey" on the top level

2. The "datasourcetype" is not a valid option name. You should change it to "dataSourceType" instead.

3. There is no need to define "odata: true".

4. There is no need to define " initialDataBindDepth: 0". This configuration is used in Load on Demand scenario.

With the given igHierarchicalGrid configuration your serialized data should look like something like this:

var data = [{"Username": "user1", "EmplID": "1", "Comment": "Comment1",

"GroupInformation": [{"Col1": "Col1 Value", "GroupName": [{"Col1": "Col1 Value"}]}]}];

If you can provide a code excerpt of your JSON data will help us identify the cause of the problems you have with binding igHierarchicalGrid to it.
I'm attaching a working sample for your reference.

Thank you so much for your help Martin!

What I tried to do (not knowing what I needed to do) was try to test the c# code with static values so i knew how to format the data coming from the database through json.  My hard code examples in c# within a razor page are below:

 @{

List<SomeClassForTheSecondBand> MyGroup = new List<SomeClassForTheSecondBand>();
List<SomeClassForTheFirstBand> UserInformation = new List<SomeClassForTheFirstBand>();

MyGroup.Add(new SomeClassForTheSecondBand() { GroupName = "GroupOne", GroupDescription = "Testing of GroupDescription" });

UserInformation.Add(new SomeClassForTheFirstBand() { Username = "Jason", EmplID = "999999", Comment = "This is a comment for Jason", GroupInformation = MyGroup });
UserInformation.Add(new SomeClassForTheFirstBand() { Username = "Jeff", EmplID = "888888", Comment = "This is a comment for Jeff", GroupInformation = MyGroup });

   }

<table id="hierarchicalGrid"></table>

<script type="text/javascript">

var data = @UserInformation.AsRawJson()

[the rest of the below is the same as what is posted above]

Thank you for your help Martin, I really appreciate your time.  You and Jon Hogue really helped a lot.  Take care.

Hello Jason,

Let me know if you need further assistance regarding this subject.

Hello Jason,
Please excuse me if I'm not going in the right direction (what I understand is that a user should have multiple groups).
You already achieved this scenario with the following model:
public class SomeClassForTheFirstBand
{

public string Username { get; set; }
public string Fullname { get; set; }
public string Comment { get; set; }
public string Acctlocked { get; set; }
public string EmplID { get; set; }
public List GroupInformation = new List();

}
However I see that in one of your previous replies you defined a third column layout - "GroupName". If that's the case then you'll need one more class:
public class SomeClassForTheThirdBand
{
public string Field1 { get; set; }
public string Field2 { get; set; }
}
In this case the definition for the "SomeClassForTheSecondBand" should be:
public class SomeClassForTheSecondBand
{
//public string GroupName { get; set; }
public string GroupDescription { get; set; }
public List GroupName = new List;
}
I'm attaching an MVC sample assembled from the information you provided

Hope this helps,

Jason,

  Thanks for posting the sample data.  As Martin had mentioned, and as we discussed on the phone, the issue is with your child collection not being serialized from the .Net to the client.  If you get that data into your data from the server, then you should have a working grid.  Just make sure the name of the property with the child collections matches the key for the columnLayout.

Cheers,

  Jon

var data = [{"Username":"Jason","Comment":"This is a comment for Jason","EmplID":"999999"},{"Username":"Jeff","Comment":"This is a comment for Jeff","EmplID":"888888"}]
