I have been able to call back into the controller, I believe that will solve the problem

Version 12.2.20122.2113

@(Html.Infragistics().Loader()
.ScriptPath(Url.Content("~/Scripts/Infragistics/"))
.CssPath(Url.Content("~/Content/Infragistics/"))
.Resources("igCombo,igGrid.Filtering")
.Theme("infragistics")
.Render()
)

The call back only partially solved the problem because it is called during the time I create them with the Razor/MVC code.

I am basically trying to create all of the grids on the page without loading any data, just setting the columns/model up and then have the events to bind to the data fire 

The problem I have is that I need to create about 20 - 30 grids on a page and it is taking a considerable amount of time. I am currently doing this through a loop with Razor code and I am debating moving it to Javascript.

I am doing something like the following

     @foreach (var physician in physicians) {

         var linkId = openCloseLink + physician.UserObjectID;

         var gridId = gridPatients + physician.UserObjectID;

         <div class="gridPatientInfo">

            @(@Html.Infragistics().Grid<PatientGridMember>()

                   .ID(gridId).PrimaryKey("PatientListMembersID")

                   .LoadOnDemand(false).AutoGenerateColumns(false).AutoGenerateLayouts(false).EnableUTCDates(true)

                   .EnableHoverStyles(true).RenderCheckboxes(true).LocalSchemaTransform(true).AutoCommit(true)

                   .Columns(GenerateChildColumns)

                   .Features(feature => {

                      feature.Sorting().Mode(SortingMode.Single);

                      feature.Selection().Mode(SelectionMode.Row).MultipleSelection(true);

                      feature.RowSelectors().EnableCheckBoxes(true).EnableRowNumbering(false);

                      feature.Resizing().AllowDoubleClickToResize(true);

                      feature.Updating().EditMode(GridEditMode.Cell).

                              EnableDeleteRow(false).EnableAddRow(false).ColumnSettings(CreateColumnSettings);

                   })

                   .DataSource(Model)

                   .DataSourceUrl(Url.Action("GetGridData", "PatientMapping2", new {  

                            patientListID =  ViewData["PatientListID"],                              

                            patientListUserObjectsID = physician.UserObjectID

                   }))

                   .DataBind()

                   .CalculateWidthAndHeight()

                   .Render()

                )

            </div>      

      }

On a side note when I hook into the iggriddatabound I can see that the dataView contains the correct data however grid.rows() is always 0 until some time later, what event is safe to hook into in order to know that the grid is fully operational

Unfortunately the MVC Render method and what is associated with it is just taking a very long time when I have a lot of grids.

I have had to remove the MVC code and put it in javascript where can create a grid every so often so as not to stop the browser from being unresponsive

Even putting up a loading message is frustrating when trying to create 30 grids and it takes several minutes

Yes,

Moving away from the MVC model allowed me greater control and solved the problem I was having.

Thanks,

Sorry had a typo -- It was supposed to say  -- javascript version is NOW  manageable

Generally I only have 2 - 3 records per grid.  I have a set of maybe 30 - 40 physicians in a hospital with each being assigned a handful of patients.

Moving to javascript/html only was not that difficult, in fact I find it perhaps a better way to keep full control of the calls I am making.  I have some improvement to do but the javascript version is not manageable, only because I can keep the page responsive because I am in control of when I created each grid.
