[Solved] rebind doesn't work for IEnumerable<DataRow> data source

[John]

Hi,

I noticed a strange issue when trying to rebind grid.

This code works fine(LineID is passed to Details grid as parameter to do data binding):

In View:

@(Html.Telerik().Grid((IEnumerable<Detail>)ViewData["DetailsData"])

        .Name("Details")

        .DataKeys(keys => { keys.Add("LineID"); })

        .Columns(columns=>

        {

            columns.Bound(typeof(string), "LineID").Visible(false);

            columns.Bound(typeof(string), "Name").Width(400).Title("Name");

            columns.Bound(typeof(string), "TotalNumber").Width(300).Title("TotalNumber");

        })

        .DataBinding(dataBinding => dataBinding.Ajax().Select("_DetailsAjax", "Test", new { LineID = "<#= LineID #>" }))

        .ClientEvents(clientEvents => clientEvents.OnDataBinding("details_onDataBinding"))

        .Pageable()

        .Sortable()

)

 

In Controller:

[GridAction]

public ActionResult _DetailsAjax(int LineID)

{

     return View(new GridModel<Detail> {

         Data = GetDetails(LineID)

     });

}

 

public IList<Detail> GetDetails(int LineID)

{

     List<Detail> details = new List<Detail>();
       // Get detail data

     return details;

}

But When I modified it to use Datatable and Datarow instead of Detail class what is defined by myself, the rebind doesn't works at all:

In View:
@(Html.Telerik().Grid((IEnumerable<System.Data.DataRow>)ViewData["DetailsData"])
        .Name("Details")
        .DataKeys(keys => { keys.Add("LineID"); })
        .Columns(columns=>
        {
            columns.Bound(typeof(string), "LineID").Visible(false);
            columns.Bound(typeof(string), "Name").Width(400).Title("Name");
            columns.Bound(typeof(string), "TotalNumber").Width(300).Title("TotalNumber");
        })
        .DataBinding(dataBinding => dataBinding.Ajax().Select("_DetailsAjax", "Test", new { LineID = "<#= LineID #>" }))
        .ClientEvents(clientEvents => clientEvents.OnDataBinding("details_onDataBinding"))
        .Pageable()
        .Sortable()
)

In Controller:
[GridAction]
public ActionResult _DetailsAjax(int LineID)
{
     return View(new GridModel<System.Data.DataRow> {
         Data = GetDetails(LineID)
     });
}

public IEnumerable<System.Data.DataRow> GetDetails(int LineID)
{
      DataTable details = new DataTable();
      // Get detail data
     return details.AsEnumerable();;
}

Can anyone help me to figure out what's wrong with it if I use IEumerable<DataRow> instead of IEnumberable<Detail>?
Thanks!!
