public EventCallback<GridReadEventArgs> OnRead { get; set; }
Property Value
Microsoft.AspNetCore.Components.EventCallback<GridReadEventArgs>

Declaration
public EventCallback<GridRowClickEventArgs> OnRowContextMenu { get; set; }
Property Value
Microsoft.AspNetCore.Components.EventCallback<GridRowClickEventArgs>

OnRowDoubleClick

Fires when the user double-clicks on a row.

Declaration
public EventCallback<GridRowClickEventArgs> OnRowDoubleClick { get; set; }
Property Value
Microsoft.AspNetCore.Components.EventCallback<GridRowClickEventArgs>
