I use Dapper and  bind grid with datatable like this

[controller]

ds = SqlHelper.ExecuteDataset(cn, CommandType.Text, "select id,fullname from tbl_profile_users");
            
return View("~/Views/user/all.cshtml", ds.Tables[0]);

[view]

 @(Html.Infragistics().Grid ()
        .ID("grid1")
        .Width("100%")
        .AutoGenerateColumns(false)
        .AutoGenerateLayouts(true)
        .RenderCheckboxes(true)        
        .PrimaryKey("id")
        .Columns(column => {

                           
                            column.For(x => x.id).HeaderText("id").Width("150px");
                            column.For(x => x.fullname).HeaderText("Fullname").Width("150px");                          
                            }
                )
                            
        
        .Features(features =>            
        {
            
            features.Paging().PageSize(5).Type(OpType.Remote).Inherit(false);
            features.Selection().Mode(SelectionMode.Row).MultipleSelection(true);
            features.Hiding().Inherit(true);
            features.Filtering();
            features.Updating().EnableDeleteRow(true);
            features.Updating().EnableAddRow(false);
            
            
        })
        .DataSource(Model)
        .DataSourceUrl(Url.Action("all_profiles"))
        .UpdateUrl(Url.Action("save_profile/"))
        .DataBind()
        .Render()
    )       

[script ]

   //
        $(function () {

            
            $("#grid1").on("iggridupdatingrowdeleting", function (e, args) {
                $("#grid1").igGrid("saveChanges");                              
            });
        });
// ]]> //
        $(function () {

            
            $("#grid1").on("iggridupdatingrowdeleting", function (e, args) {
                $("#grid1").igGrid("saveChanges");                              
            });
        });
// ]]>
