UI for ASP.NET MVC Forum

So, I am using UI for ASP.NET MVC Q1 2015. I have 3 DDLs, configured to populate their data remotely(from action method inside a controller) using DataSource/Read action AJAX pattern.

I have some custom business logic I need to implement: when something gets changed in the 1st DDL, I have to do some custom calculations that may potentially involve what it has been selected in 2nd DDL so I can eventually change the selected values in the 3rd DDL.
So this here has nothing to do with datasource filtering or custom cascading.

My issue/concern here is: how can I do any such calculations/alterations of the other DDLs from inside a 'Changed' event handler in the 1st one safely, given all 3 are populated asynchronously? I mean, how can I be sure that when inside the Changed event handler in 1st DDL, data for 2nd & 3rd DDL had been fully loaded so I can use them in calculations and/or change the Selected value for those DDLs?

Thanks!

Hi,

We are using a pop up window to display information about a selected item in a grid.  When the user selects the grid item the window appears but it then has focus.

Is there a way to pop-up the window but retain focus on the calling control?

Regards,

Mark.

In the attached image, we are having issues with the menu bar and spacing between the sub menu's.  We are currently running Kendo.UI 2013.2.918.  Do the newer versions of Kendo fix this "bug" or is there an fix that we can do with our current version?  The screen print is from Chrome version 42.0.2311.135

 

Code:

 

@(Html.Kendo().Menu()
                  .Name("Menu")
                  .HtmlAttributes(new { @style = "width:99%;border: 0px;"})
                  .Direction(MenuDirection.Bottom)
                  .Items(items =>
                  {
                      items.Add().Text("home").Action("Index", "Home").ImageUrl(Url.Content("~/Images/B-home%2048.png")).ImageHtmlAttributes(new { style = "width:25px" });
                      items.Add().Text("search").Action("Index", "Search").ImageUrl(Url.Content("~/Images/B-search%2048.png")).ImageHtmlAttributes(new { style = "width:25px" });
                      items.Add().Text("activities & alerts").ImageUrl(Url.Content("~/Images/B-Activity%2048.png")).HtmlAttributes(new { style = "width:175px" }).ImageHtmlAttributes(new { style = "width:25px" }).Items(children =>

Hi,

 I'm trying to use a MobileListView in my project with this code:

 

<div class="row">
    <div class="col-xs-12">
        @(Html.Kendo().MobileView()
       .Title("Chiamate")
       .Header(obj =>
            Html.Kendo().MobileNavBar()
                .Name("ChiamateNavbar")
                .Content(navbar =>
                    @<text>
                        @navbar.ViewTitle("Chiamate")
                    </text>)
        )
       .Content(
    @<text>
        @(Html.Kendo().MobileListView<Telesan.CloudLift.WebApplication.Models.Chiamate.ChiamataListViewModel>()
                    .Name("ChiamateListView")
                    .TemplateId("ChiamateTemplate")
                    .PullToRefresh(true)
                    .EndlessScroll(true)
                    .DataSource(dataSource =>
                        dataSource
                            .Read(r => r.Action("ChiamateAjaxList", "Chiamate").Data("onData").Type(HttpVerbs.Post))
                            .ServerOperation(true)
                            .Filter(t =>
                        {
                            t.Add(m => m.DataOra).IsGreaterThanOrEqualTo(DateTime.Today.AddDays(-3));
                            t.Add(m => m.IDStato).IsNotEqualTo((Guid)ViewBag.StatoChiuso).And().IsNotEqualTo((Guid)ViewBag.StatoElaborato);
                        })
                        .Sort(s => s.Add(m => m.DataOra).Descending())
                            .PageSize(50)
                    )
        )
 
    </text>)
        )
    </div>
</div>

But it doesn't render to my page so after a search I've found a possible solution by adding this in _L:

@(Html.Kendo().MobileApplication()
        .ServerNavigation(true)
    )
I can see some differences now, the page style has changed but the listview is not yet appeared.

Your kendo mobile application element does not contain any direct child elements with data-role="view" attribute set. Make sure that you instantiate the mobile application using the correct container.
But I didn't find a solution for this problem with ASP.NET MVC Wrappers.

This is the _Layout block where @RenderBody is:

<div class="cloudlift-container">
        <div class="row">
            <div class="col-xs-12 main-content">
                @RenderBody()
            </div>
        </div>
    </div>
 
    @(Html.Kendo().MobileApplication()
        .ServerNavigation(true)
    )
I don't know how to tell to MobileApplication helper to find the div inside my structure as seen in examples found about KendoUI Professional.

Can somebody help?

The documentation doesn't show that there are events for the ImageBrowser, such as Change, Upload, etc.  Are there any?

If not, it would be nice in a future version, this way I can wrap my images in an HTML snippet for styling when I click Insert Image.

Just a thought.

I have a grid that has joined tables from a doamin method entity.

I want to edit the grid columns. for some reason, I keep getting a null value for some of the grid colunms.

public ActionResult EditSubscriber([DataSourceRequest] DataSourceRequest gridRequest, Sub editSub, Subs editSubs)
        {
            if (ModelState.IsValid) 
            {

               // Passin values
                Sub subToUpdate = db.Subss.FirstOrDefault(s => s.Sub_ID == editSub.Sub_ID);                
               subToUpdate .SFirstName = editSub.SFirstName;
               subToUpdate .SLastName = editSub.SLastName;
               subToUpdate .SEmail = editSub.SEmail;

               // Null values. Values are not being passed. Why?

                Subs subsToUpdate = db.Subsss.FirstOrDefault(s => s.Subs_ID == editSubs.Subs_ID);
               subsToUpdate .SubsStartDate = editSubs.SubsStartDate;
               subsToUpdate .SubsEndDate = editSubs.SubsEndDate;
               subsToUpdate .SubsStatus = editSubs.SubsStatus;
               subsToUpdate .SubsType_ID = editSubs.SubsType_ID;
                
                db.SaveChanges();
            }

            return Json(new[] { editSub}.ToDataSourceResult(gridRequest, ModelState));
        }

 

Any idea?

 I would like to know how to retail the page size that is selected in the pager?

Suppose I select 20 as pagesize on a list page.

I do editing of a row by opening a new page.

Then I come back after completing editing on the list page. Here the count again becomes default (i.e 10)  and not 20. How do I preserve this or make this work? I have items more than 10...

 I tried both the options give below but nothing seems to be working... Please provide solution.

 .Pageable(pager => pager.PageSizes(new int[] { 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100, 200, 500 }))

 
                                      .Pageable(pageable => pageable
                                          .Refresh(true)    //false also tried..
                                      .PageSizes(new int[] { 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100, 200, 500 })
                                      ////.Input(true)

                                         )

I have a grid with data on it. When I want to edit the data, I need to press the edit button and a new edit form will open with the current data from the row.

For the textboxes I use: 

@Html.EditorFor(model => model.SubStatus)

Now the issue is the dropDownList. Here is my code. the initial value is always blank?

CSHTML code:

@(Html.Kendo().DropDownListFor(m => m.SubType)
                .Name("SubsType") 
                .DataTextField("SubType1")
                .DataValueField("SubType_ID") 
                .DataSource(source =>
                {
                    source.Custom()
                          .ServerFiltering(true)
                          .Type("aspnetmvc-ajax")
                          .Transport(transport =>
                          {
                              transport.Read("GetType", "Welcome");
                          })
                          .Schema(schema =>
                          {
                              schema.Data("Data")
                                    .Total("Total"); 
                          });
                })
            )

 

Razor code:

 public JsonResult GetSubType([DataSourceRequest] DataSourceRequest dropDownRequest)
        {
            IList<SubType> myViewModels = new List<SubType>();

            foreach (SubType subType in db.ExecuteStoredProcedure<SubType>("proc_getType", null))
            {
                SubType subtype = new SubType()
                {
                    SubType_ID = subType.SubType_ID,
                    SubType1 = subType.SubType1
                };
                myViewModels.Add(subtype);
            }
            return Json(myViewModels.ToDataSourceResult(dropDownRequest), JsonRequestBehavior.AllowGet);
        }

Right now I get the list from the database. when the dropdownlist is pressed. but I want to set the initial value of the list to be the current value. How to do it?

From an example in another thread, I was able to enable dragging from a grid onto a TreeView control.

However, the example just fired an alert with the ID of the object that was dragged. What I need to do is insert the dragged row into the TreeView . I can use the append method to add to the TreeView , but can't work out how to identify the node that the grid record was dragged onto.

 

My current client code is:-

<div class="pull-left" style="margin-right:20px;">
 
    @(Html.Kendo().TreeView()
                    .Name("Treeview")
                    .ExpandAll(true)
                    .HtmlAttributes(new { style = "display: inline-block;" })
                    .DataTextField("Text")
 
                    .DataSource(ds=>ds
                        .Model(m=>m
                            .Id("Id")
                            .HasChildren("HasChildren")
                            .Children("Items")
                             
                            )
                        
                    .Read(r => r.Action("GetMenuTreeItems", "Menu")
                              
                            )
                            )
    )
 
</div>
 
<div class="pull-left" style="width:500px;">
    @(Html.Kendo().Grid<BI_II.Models.SSRS_Report>()
.Name("Grid")
.Columns(col =>
    {
        col.Bound(o => o.Name).Title("Name");
        //col.Bound(o => o.ItemID).Title("ItemID");
    })
 
  .DataSource(ds => ds
    .Ajax()
    .Model(m => m.Id(p => p.ItemID))
    .PageSize(15)
        .Read(rd => rd.Action("RD_ReportList", "Menu")
    )
)
.Pageable()
.Sortable()
.Filterable()
 
    )
</div>
<script>
 
    $(document).ready(function () {
 
        var grid = $("#Grid").data("kendoGrid"),
             treeview = $("#Treeview").data("kendoTreeView"),
            itemUID;
 
        grid.table.kendoDraggable({
            cursorOffset: {
                top: 5,
                left: 5
            },
            filter: "tbody > tr",
            group: "Grid",
            hint: function (e) {
                itemUID = e.attr(kendo.attr("uid"));
                return $('<div class="k-grid k-widget"><table><tbody><tr>' + e.html() + '</tr></tbody></table></div>');
            }
        });
         
        treeview.element.kendoDropTarget({
            group: "Grid",
            drop: function (e) {
 
                var model = grid.dataSource.getByUid(itemUID);
 
                 treeview.append({ Text: model.Name, Id: model.ItemID });
 
       
 
                itemUID = null;
            }
        });
 
    });
</script>

 This currently just appends into the TreeView root node.

 Thanks

Is it possible to add a kendo context menu to a TreeView node?  I can't seem to find any examples or posts about this.

 

Thanks
