  Hi Alex,
  
  If we are correct, you are referring to the AJAX data binding. AJAX provides error callback which will be called when called url throws any error. You can handle this error in your way by showing alert or div.

  For reference, please refer to point 2 of Step 4 on http://helpcentral.componentone.com/nethelp/c1mvchelpers/AjaxBinding.html page.

  For puting Input field in some columns, what you mean from this?

  As we understand, you would like to place an input field for each column separately. In this case, you can use CollectionView filter method.

  For reference, please refer to Filtering section on http://helpcentral.componentone.com/nethelp/c1mvchelpers/AjaxBinding.html page.

  Hi,

  Not quite correctly

  1. I use Helper (for example)

  
  Html.C1().FlexGrid<Sale>()
          .Id("SaleGrid")
          .AutoGenerateColumns(false)
          .HeadersVisibility(HeadersVisibility.Column)
          .IsReadOnly(true)
          .SelectionMode(SelectionMode.None)
          .Bind(Url.Action("Grid"))
  ....
          })
  
  

  As you see I bind data with action Grid. But if in action will be
  
  exception user not see any alert or message. I want to display error if it is.

  2. I mean something similar to the one in the screenshot

     Field that automaticaly search in specified columns.

  Hi Alex,
  
  For this, you need to track error in Controller and use ViewBag to show error in View page. Please refer to following links that may be useful:

  https://stackoverflow.com/questions/37043427/asp-net-mvc-url-action-gives-404-resource-not-found-error

  For applying filter mentioned in screenshot, you should refer to the CollectionView Intro demo filtering section.
  
  We are sorry for the false link in the previous reply:
