My goal is to get all currently visible rows in the grid.
In order to do that I’ve been trying to use GetVisibleRows() but I’ve been getting the following Exception:

Microsoft.JSInterop.JSException: Converting circular structure to JSON

My grid looks like this:

<Grid @ref="grid" DataSource="@data">
<Columns>
<Column DataField="Id" Width="auto" Visible="false" AllowEdit="false"/>
<Column DataField="Name" Label="Name" AllowEdit="true"/>
<Column DataField="BoolValue " Label="BoolValue" AllowEdit="true" DataType="boolean" Editor="@checkBoxEditor" Template="@checkBoxEditor"/>
</Columns>
</Grid>

My class look something like this, with @data being List<ClassName>

public class Entity
{
public Guid Id { get; set; }
}

public class ClassName: Entity
{
public string Name { get; set; }
public bool BoolValue { get; set; }
}

What am I doing wrong?

Hi wolf.t,

Could you share a link to an example in github which we can download and try locally? From the call stack it seems that this is related to the result returned by the method, but we will need to look into that by debugging it.

Looking forward to your reply.

Best regards,

Markov

Hello,

 

colleague of wolf.t here.

 

Please see https://github.com/DiawaKG/reproduction-smarthtml-grid-getvisiblerows-exception.

Running the Server project and clicking the Button “Click Me” on the index page reproduces the problem.
