In order to add a menu item in WebGrid’s row context menu, please try to use following approach.

function WebGrid1_OnRowContextMenu(controlId, rowType, rowElement, menuObject)
{
    var WebGrid1 = ISGetObject(controlId);
    var separator = new WebMenuItem();
    separator.Type = "Separator";
    separator.Name = "MySeparator";

    var menuItem = new WebMenuItem();
    menuItem.Text = "Paste and Save";
    menuItem.Name = "MyMenu";
    menuItem.OnClick = "PasteandSave";

    // Add Menu Separator and Menu Item    
    menuObject.Items.Add(separator);
    menuObject.Items.Add(menuItem);

    return true;
}

function PasteandSave()
{
    var grid = ISGetObject("WebGrid1");
    //implement the paste and save logic in here
}

After the context menu appearing and user click the “Paste and Save” menu item, “PasteandSave()” function will be invoked. You will need to implement the logic of paste and save scenario in here.

Hope this helps.

Hi

Thanks for that, apologies, I wasn't very clear in my initial question.

It's the Paste and Save functionality I need as I don't know how to trigger those events and can't find it in the documentation, the server side functionality for doing the work is in place i just need to know how to call Paste and Save from the client side.
