Hi,
    I am using ajax binding for my grid. There's a parameter generated by javascript and I need to pass it to server when user invokes a delete action. I use client event OnDelete and set e.data = { productId: currentModel.Id } in the handler. But when I watch the request body in Fiddler I found the "productId" is not included in post body. I use this method in databinding handler and it works fine. But it seems not ok in delete handler.
   Could someone tell me how to pass a parameter along with delete request?
   Thanks a lot.

Hi Ian,

In order to modify the posted values, when saving the grid's edit form, you should use the values property of the event's argument object . For more detailed information, please refer to this help article (under OnSave section).

Hi,

Did this post adequately resolve the issue?  For me at least (and based on the linked-to documentation) onSave doesn't get fired for a delete.

Adding parameters works fine using the e.values argument for saving and updating, but any additional parameters placed in e.values or e.data (onDelete function) are still ignored.  How do i pass additional parameters through to the onDelete action?

After a bit of trial and error, i found the best way to add additional parameters to the delete function was to include them in the datakeys collection.  So along with storing the id of the record, i also put the id of the category the record belongs to so that i can reload the grid with the correct category filter.

Hi

I'm new to Telerik controls, so I'm probably missing something.

I have used grid control with server binding, but unable to fire the action defined for Delete.  

I have put breakpoints in the grid methods but there is no indication they fire.

Here is my View:

   "DisplayProducts" is List<Products>

@using (Html.BeginForm())
{
   @(Html.Telerik().Grid(Model.DisplayProducts)
        .Name("selected-product-grid")
            .DataKeys(keys =>
           {
               keys.Add(x => x.Id);
          })
  .Columns(columns =>
  {
  columns.Bound(x => x.Name);
  columns.Command(c => c.Delete());
    })
 .DataBinding(db => db.Server()
 .Delete("ProductAddPopupDelete", "Discount", new { discountId = Model.DiscountId }))
 .Footer(false)
 )
}

Here is my controller action method :

[HttpPost, GridAction]
public ActionResult ProductAddPopupDelete(int id, int discountId, GridCommand command)
{
    var discount = _discountService.GetDiscountById(discountId);
    if (discount != null)
    {
        //TODO: perform some action
    }
    return ProductAddPopup(discountId);
}

What am I missing from making these actions fire?

Thanks
