Hi,

With filterable->mode set to row, is it possible to filter a date between two dates? I ​found this thread http://www.telerik.com/forums/how-to-define-a-kendo-grid-column-filter-between-two-dates, and currently have ​it applied ​to grid menu filter, but not sure how to make it work when the filterable mode is row.

Thanks,

Lisa

I am in need of some help, I'm building a web application that uses the KendoUI, specifically the grid to display data.  I've used the entity framework under a "database first" scenario, this means that the models are created for me for all the tables in my database.  I'm displaying this data in the Kendo grid but I can't edit or delete any of the entries (inline with ajax).  If you delete an item it returns when you regresh the screen and the update button does nothing.  I suspect this is because we have no functions to handle these events.

Is there anyway I can utilise the already created scaffolded controller to do this as it already as an edit and delete function in it.

 Any help would be appreciated.

Hi,

I have 2 Kendo Grids in which 2nd grid is read based on the selection of row of 1st grid. The code is:

1st grid

        <% Html.Kendo().Grid<EvaluationsQuestionsEvaluationVersionGridViewModel>(Model.VersionsGridModel)
            .Name("Versions")
           .DataSource(dataSource => dataSource
                    .Ajax()
                    .Model(model => model.Id(a => a.EvaluationVersionId))
                    .ServerOperation(true)
                    .Create(create => create.Action("InsertEvaluationVersion", "Evaluations"))
                    .Read(read => read.Action("LoadEvaluationsQuestionsEvaluationVersionGridAjax", "Evaluations"))
                    .Update(update => update.Action("UpdateEvaluationVersion", "Evaluations").Data("onUpdateEvaluationVersion"))
                )
            .Events(e => e.Change("onVersionGridRowSelect")
                          .Edit("onEditEvaluationsVersion")
                          .Save("onSaveEvaluationsVersion")
                    )​

.....

2nd grid

        <% Html.Kendo().Grid<EvaluationsQuestionsEvaluationPillarsGridViewModel>()
            .Name("Pillars")
            .DataSource(dataSource => dataSource
                  .Ajax()
                  .Model(model => model.Id(a => a.EvaluationMasterPillarId))
                  .ServerOperation(true)
                  .Read(read => read.Action("LoadEvaluationsQuestionsEvaluationPillarsGridAjax", "Evaluations")
                                    .Data("onLoadEvaluationsQuestionsEvaluationPillarsGridData"))
             )​

......

        function onVersionGridRowSelect(e) {
            var grid = $("#Versions").data("kendoGrid");
            var currentRow = grid.dataItem(grid.select());
            var evaluationVersionId = currentRow.EvaluationVersionId;

            $('#evaluationVersionId').val(evaluationVersionId);
            $("#Pillars").data("kendoDropDownList").dataSource.read();
        }

        function onLoadEvaluationsQuestionsEvaluationPillarsGridData(e) {
            var evaluationVersionId = $('#evaluationVersionId').val();  // "evaluationVersionId" is set beforehand
            var showDeletedCheckbox = $('#Checkbox1').val();

            return { evaluationVersionId: evaluationVersionId, showDeleted: showDeletedCheckbox }
        }

But 2nd grid can not be read because Data function "onLoadEvaluationsQuestionsEvaluationPillarsGridData" is not called. So what is the problem in code?​ Thanks.

Hello to all.

I'd like to validate a field, for example the standard Title field in an Calendar Event.

The validation works well in the BASIC example:

http://demos.telerik.com/aspnet-mvc/scheduler/index

I added the [Required] attribute on the Model.

Anyway in my code, the generated HTML code doesn't have the "required" attribute end not any validation is performed.

Someone can help me please?

I have a chart which has too many values to fit comfortably on the screen all at once.

 I have made it pannable and zoomable as per the demo example.  This works, but the chart initially still opens with all the columns squashed onto the screen.

How can I set a fixed zoom level (which the user can't change) to enable panning of the chart?

Also, will a scrollbar or other visual indicator that a chart can be panned be added soon? Currently it's not very user friendly, and requires an application to find a way to tell users how to scroll the chart. Alternatively, can panning be activated by JavaScript, so some left / right buttons can be added?

The chart code is:-

Thanks

Hi.

I would like to open multiple popup windows from ActionLinks within a grid.

The column template for the single-column grid is such...

        string Template =
            "<tr>" +
                "<td>" +
                    "<div class='ResultListing'>" +
                        "<div class='Technical'>" +
                            Ajax.ActionLink("#:CompanyName#, #:MfgModelNumber#", "GetDetails", "Services", new { ComponentID = "#:ComponentID#" },

                                       new AjaxOptions() { HttpMethod = "POST" }, new { @class = "ResultsTitle" }) + "<br />" +

                            "<span>MPN: #:MfgPartNumber#</span><br/>" +
                            "<span>Key: #:ConfigurationKey#</span><br/>" +
                        "</div>" +
                        "<div class='Space'>" +
                        "</div>" +
                        "<div class='Technical'>" +
                            "<span>Description: #:DesignDescription#, #:CategoryDescription# </span><br/>" +
                            "<span>Elastomers: #:(Elastomers == '0') ? 'N/A' : Elastomers#; Materials: #:(Materials == '0') ? 'N/A' : Materials#</span><br/>" +
                            "<span>Sizes: #:(Sizes == '0') ? 'N/A' : Sizes#; </span><br/>" +
                            "<span>Configuration: #:Configurations# </span><br/>" +
                            "<span>Leyla ID: #:ComponentID# (#:ComponentStatus#)</span>" +
                        "</div>" +
                        "<div id='PictureDiv' class='ControlAndLabel AlignCenter'>" +
                            "# if (URL.length > 0) { #" +
                                "<img src='#:URL#' class='ComponentImg'/><br/>" +
                                "<span>#:ImageDescription#</span>" +
                            "# } else { #" +
                                "&nbsp;" +
                            "# } #" +
                        "</div>" +
                    "</div>" +
                "</td>" +
            "</tr>"
            ;

​The Ajax.ActionLink should be able to open a new popupwindow based on the ID contained in the grid for that row.  The controller will return a partial view to the popup window...

        [HttpPost]
        public PartialViewResult ​GetDetails(int ComponentID)
        {

            PartialViewResult Result = PartialView("_ComponentDetailView", ComponentID);

            return (Result);
        }

The popup windows are not modal, so that multiple ​popups can be opened at the same time.  The user can click multiple links from the grid, popping up multiple detail windows at the same time.

The detail popups should fetch data from a database only when activated.

I am rather new to MVC and to the Kendo tools.  At this point, I am not even sure this is the best way to do it.  I am hoping a new Kendo Window can be instantiated ​by clicking the Action link in the grid and populated by somehow passing in the id of the object whose details the user wants to see.

Any help would be appreciated.

Hi,

I need to select both row and client detail template of the row when we click in the client detail template area or click the button inside the client detail template.

For this I have used the onclick event of the div. But it is not working.

Also I need to get the row data when we click in the client detail template area or click the button inside the client detail template.

Can any one provide the solution for this .

Hello,

I have hierarchical data in DB implemented as closure table. Imagine hundreds of nodes with parent-child relationship. Now I would like to display data, edit nodes, create new nodes, change hierarchy with drag&drop, filter nodes (show only nodes which starts with given word).

TreeList has this CRUD operations ready for use, but I was not able to detect drag&drop event for persisting the change in DB. Yes, its possible to add the button for "save", but I would like to do the change automatically.

So I tried TreeView. TreeView with popup-menu for adding root node, child node, etc. But I have problem with "editing". When I use demo for edit node in separate form, loading child's node stops working.

So, I would like to ask for hint or complex example of CRUD operations in TreeView or maybe to say me, that TreeView is not intended for this operations :)

Thank you
