[Solved] Batch Editing Binding Issue

[Guilherme]

Hello Telerik People

I have created a simple application which entities as Order and OrderRow.
Wtih a Grid in InCell editing mode I'm managing some data.

@{Html.Telerik().Grid<Volvo.POS.MVCWebUIComponent.Models.Entities.OrderRow>()

    .Name("GridOrderRowRequest")
    .DataBinding(bind => bind.Ajax()
        .Select("GridOrderRowRequest_Select", "Order")
        .Update("GridOrderRowRequest_Update", "Order", new { orderNumber = Model.Number }))
    .DataKeys(conf => conf.Add(exp => exp.Number))
    .Columns(columns =>
    {
        columns.Bound(o => o.Number).Visible(true);
        columns.Bound(o => o.Part.Name).Width(180).Title("Name").ReadOnly();
        columns.Bound(o => o.RequestedQuantity).Title("Request").Format("{0:d} (click to edit)");
    })
    .ClientEvents(e => {
        e.OnDataBinding("GridOrderRowRequest_OnDataBinding");
        e.OnEdit("GridOrderRowRequest_OnEdit");
        e.OnSave("GridOrderRowRequest_OnSubmitChanges");
    })
    .Editable(e => e.Mode(GridEditMode.InCell))
    .Selectable()
    .Scrollable(conf => conf.Height(150))
    .Render();
}

But I have handling the buttons events on my own. So I have something like:

grid.insertRow(data.Content);
grid.submitChanges();

I receive the data in a controller method, something like:

[GridAction]
        [HttpPost]
        public ViewResult GridOrderRowRequest_Update(
            [Bind(Prefix = "inserted")]IEnumerable<Entities.OrderRow> insertedOrderRows,
            [Bind(Prefix = "updated")]IEnumerable<Entities.OrderRow> updatedOrderRows,
            [Bind(Prefix = "deleted")]IEnumerable<Entities.OrderRow> deletedOrderRows,
            int orderNumber)
        {
...

For some reason in the updatedOrderRows, when I'm editing some existent data, the Number field from my entity is not binded with the values sent. But this happend only with Number, all others fields are ok.

To solve this I had to use some ugly code like:

orderRow.Number = Convert.ToInt32(HttpContext.Request.Form["updated[" + i + "].Number"]);

Since I dont need the Number, the insert function are ok.

Do you know why? ??

Hi Guilherme,

I believe the reason for this behavior is that the ModelBinder is getting the value from the route values not from the form data because you have datakey called Number (which contains the original value):
.DataKeys(conf => conf.Add(exp => exp.Number))
and also you have a column with the same name (which should contain the updated value).
columns.Bound(o => o.Number).Visible(true); 

Could you try to use different name for the RouteKey and see if it helps?
e.g.

.DataKeys(keys=>keys.Add(p=>p.Number).RouteKey("NumberKey"))

Finally I discovered the reason.

In the OrderRow entity, I had:

[ReadOnly(true)]
public int Number { get; set; }

The attribute ReadOnly just tell to ModelBinder to dont bind.
After I removed it, everything start to work again :)

Thanks anyway!
