Blazor DataGrid Event Compile Error

Radzen.Blazor Components

I am trying to use the "OnColumnResized" event to determine when a column has resized. However, the code at the following location produces and error: Cannot Convert from MethodGroup to EventCallback

I have copied the code exactly; might there be a newer way to do this?

No, the code in the example is the one used by the runnable application so it should work as expected. Can you paste here your declaration and method implementation?

<RadzenDataGrid
@ref="requestGrid"
AllowFiltering="true"
AllowPaging="false"
PageSize="1000"
AllowSorting="true"
AllowColumnResize = "true"
EditMode="DataGridEditMode.Single"
Data="Requests"
TItem="Request"
RowUpdate="@OnUpdateRow"
RowCreate="@OnCreateRow"
Style="height:1000px;width:120%"
ColumnResized="OnColumnResized">
...
...
//In code:
void OnColumnResized(Radzen.DataGridColumnResizedEventArgs args) {
}

The event argument is generic - see our example:

  void OnColumnResized(DataGridColumnResizedEventArgs<Employee> args)

This is your example:

@code {
IEnumerable employees;
EventConsole console;

void OnColumnResized(DataGridColumnResizedEventArgs<Employee> args)
{
    console.Log($"Resized {args.Column.Title} to {args.Width} pixels");
}

protected override void OnInitialized()
{
    employees = dbContext.Employees;
}

}

Oh, I finally got it. That shook my brain loose a bit. I needed TItem of Request from my grid in there.
