I'm trying to add an onClick event when clicking on a custom command. So far I managed to display the custom command but when clicking on the icon the event is not fired. The code is:

    List<object> commands = new List<object>();
    commands.Add(new { type = "Edit", buttonOption = new { iconCss = "e-icons e-edit", cssClass = "e-flat" } });
    commands.Add(new { type = "Delete", buttonOption = new { iconCss = "e-icons e-delete", cssClass = "e-flat" } });
    commands.Add(new { type = "Save", buttonOption = new { iconCss = "e-icons e-update", cssClass = "e-flat" } });
    commands.Add(new { type = "Cancel", buttonOption = new { iconCss = "e-icons e-cancel-icon", cssClass = "e-flat" } });
    commands.Add(new {click="PrintSomething", type = "My Custom Action", buttonOption = new { iconCss = "e-icons e-cancel-icon", cssClass = "e-flat" } });
<EjsGrid id="Grid" DataSource="@gridData">
    <GridEditSettings allowAdding="true" allowEditing="true" allowDeleting="true" Mode="@EditMode.Dialog"></GridEditSettings>
        <GridColumn ref=@col Field=@nameof(OrdersDetails.CustomerID) HeaderText="Customer Name" Width="120"></GridColumn>
        <GridColumn Field=@nameof(OrdersDetails.OrderDate) HeaderText=" Order Date" Format="yMd" TextAlign="@TextAlign.Right" Width="130"></GridColumn>
        <GridColumn Field=@nameof(OrdersDetails.Freight) HeaderText="Freight" Format="C2" TextAlign="@TextAlign.Right" MinWidth="10" Width="120" MaxWidth="200"></GridColumn>
        <GridColumn Field=@nameof(OrdersDetails.ShipCountry) HeaderText="Ship Country" Width="150"></GridColumn>
        <GridColumn HeaderText="Manage Records" Width="120" Commands=commands></GridColumn>

Are there samples of how to do this in C# without the use of the command list approach?

I get errors like: Cannot convert lambda expression to type 'EventCallback<object>' because it is not a delegate type.

                        <GridCommandColumn Type="CommandButtonType.None" Title="abc" 
                                           ButtonOption="@(new CommandButtonOptions()
                                                               IconCss = "remove-image-icon icon-image",
                                                               Click = (item => Xyz(item))
                                                           })" />

Hi Patrick, 

Thanks for contacting Syncfusion support. 

We suggest you to use the “CommandClicked” event of Grid. We have provided support to trigger “CommandClicked” when the command button in Grid is clicked. The event’s handler will have arguments, based on the clicked button.  

Please use the code below, 

<EjsGrid @ref="GridInstance" TValue="Order" AllowPaging="true" DataSource="@Orders"> 
    <GridEvents CommandClicked="CommandClickHandler" TValue="Order"></GridEvents> 
        <GridColumn HeaderText="Navigation" Width="120"> 
                <GridCommandColumn Type="CommandButtonType.None" Title="abc" 
                                   ButtonOption="@(new CommandButtonOptions() 
                                                               IconCss = "remove-image-icon-icon-image", Content="customcommand" 
                                                           })" /> 
   public void CommandClickHandler(CommandClickEventArgs<Order> args) 
        //Perform your custom command button click operation here. And also with the value in “args” you can differentiate the buttons, if having multiple custom command buttons. 

We have also prepared a sample based on this. Please download the sample form the link below, 
Please get back to us if you need further assistance. 

Renjith Singh Rajendran.
