When theplanonUserObject is null i getSystem.NullReferenceException: Object reference not set to an instance of an object.
How can i get arround this?

I have a JSON object like this:
{
"samaccountname": "xxx",
"userprincipalname": "xxx",
"planonUserObject": null
},
{
"samaccountname": "yy",
"userprincipalname": "yy",

Hi Renjith Singh Rajendran,
I just saw that is missed the grid code:
<SfGrid @ref="@Grid" DataSource="@GroupDataList" AllowSelection="true" RowHeight="60" Toolbar="@(new List<string>() { "search" })">
            <GridSelectionSettings Type="SelectionType.Single"></GridSelectionSettings>
            <GridColumns >               
                </GridColumn>
                <GridColumn Field=@nameof(ADUserObject.displayname) HeaderText="Name" TextAlign="TextAlign.Left"
                            Width="250" MinWidth="250" MaxWidth="275" IsFrozen="true"></GridColumn>
                <GridColumn Field=@nameof(ADUserObject.initials) HeaderText="Initialen" TextAlign="TextAlign.Left" Width="35"></GridColumn>

                <GridColumn Field=@nameof(planonUserObject.eMail) HeaderText="Voornaam" TextAlign="TextAlign.Left" Width="65"></GridColumn>
                    ......
            
If plannonUserObject is null i get System.NullReferenceException: Object reference not set to an instance of an object.

Hi Rauden, 

Thanks for your update. 

As provided in the sample and documentation shared from our previous update, we suggest you to set the Field property as like the below code to overcome the reported problem. 

 
<GridColumn Field="planonUserObject.eMail" HeaderText="Date" ... ></GridColumn> 


Please find the documentation for your reference, 

Regards,
