Hi,

I have a problem that i'm not entirely sure how to describe.  So, starting from the beginning: I have a view that has a list of parts and projects.  When a part or project is clicked, a kendo window is opened and loads a partial view containing information about the part or project and other kendo objects (buttons, text boxes, drop downs).  The first time a project/part is clicked the window loads fine, and even if the user only clicks projects the window loads fine.  But if a user clicks a project/part, closes the window, and then clicks the other (either a project or a part) all kendo objects in the window stop working.  They lose their styling and their functionality.  For example, drop down boxes are no longer drop downs but just a textbox, and not  a kendo text box, just a regular one.  Buttons turn a dark blue color, lose their styling, and lost their function. And text boxes lose their styling.  I've had similar problems before, and I fixed it with name changes of the objects or fixing the javascript functions they link too.  Neither worked in this case.  I'm not sure what else to try, but all help is welcomed.

 I'm reluctant to post all of my code because of my NDA (I'm an intern) but here is the code of the buttons for one of my partial views.  The names of all the objects in both windows are different, as in a button that serves the same purpose and displays the same info in partial1 is named differently than in partial2, and neither share a name with an object in the rest of the project.

  <div style="width:100%;text-align:center;">
        <div style="display:inline-block; vertical-align:central">
            <table>
                <tr>
                    <td>
                        @Html.Kendo.Button.Name("test1").Content("Add Costs").Events(Sub(events) events.Click("enterActualInfo"))
                    </td>
                
                    <td>
                        @Html.Kendo.Button.Name("test2").Content("View Change History").Events(Sub(events) events.Click("showProjectHistory"))
                    </td>
                
                    <td>
                        @Html.Kendo.Button.Name("test3").Content("Target").Events(Sub(events) events.Click("addTarget"))
                    </td>
                </tr>                
            </table>
        </div>
    </div>
    
   
<script>
    function enterActualInfo() {
        debugger;
        alert("test1");
    }
    function showProjectHistory() {
        alert("test2");
    }
    function addGPC() {
        alert("test3");
    }
</script>

I noticed some differences between buttons that work and buttons that don't in the IE DOM Explorer. It seems that the objects are not inheriting the kendo properties.       Functioning button: <button tabindex="0" class="k-button" id="addPart" role="button" aria-disabled="false" data-role="button">Add Part</button>Not functioning button: <button  id="addPart" role="button">Add Part</button> 

I've attached pictures of the difference between functioning and non functioning buttons.

Thanks in advance!

Hi Team,

Please provide the sample code for kendo grid  cascading drop down using model. 

And also please share, how to get the entire source(all rows of existing grid) of grid.

Thanks

Hi Team, 

 Please let me know how to get the foreign key drop down (InstanceTypeIds) selected value using Jquery to send input value to cascading drop down (InstanceId) of grid row.      @(Html.Kendo().Grid<Flextronics.DevFactory.Ingrex.Entity.IngrexDataEntity.IngrexGlobalNewRequest>()

    .Name("GridGlobalNewRequest")
    .Columns(columns =>
    {
        columns.ForeignKey(p => p.InstanceTypeIds, (System.Collections.IEnumerable)ViewData["listofinstanceTypes"], "InstanceTypeId", "InstanceTypeName").Title("InstanceType").Width(120).EditorTemplateName("InstanceTypeIds");
        columns.ForeignKey(p => p.InstanceId, (System.Collections.IEnumerable)ViewData["listofInstance"], "InstanceId", "InstanceNm").Title("Instance").Width(120).EditorTemplateName("InstanceId").Width(120);
        columns.Bound(p => p.StartCompany).Title("Start").Width(90);
       // columns.Command(command => command.Edit()).Width(80).HtmlAttributes(new { style = "text-align:center" });
        columns.Command(command => command.Destroy()).Width(80).HtmlAttributes(new { style = "text-align:center" });
    })
            .ToolBar(toolbar => {
                toolbar.Create();
                toolbar.Save();
            })

    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .Pageable(page => page.Enabled(true).PageSizes(new int[] { 10, 50, 100, 500}))
    .Sortable()
    .Scrollable()

    .DataSource(dataSource => dataSource
                .Ajax()

                .PageSize(20)                

                .Model(model =>
                {
                    model.Id(p => p.InstanceTypeIds);
                    model.Field(p => p.InstanceId);
                    model.Field(p => p.InstanceTypeIds);
                })


            //.Create(update => update.Action("EditingInline_Create", "NewRequest"))
            //.Read(read => read.Action("EditingInline_Read", "NewRequest"))
            //.Update(update => update.Action("EditingInline_Update", "NewRequest"))
            //.Destroy(update => update.Action("EditingInline_Destroy", "NewRequest"))

                .Create("EditingInline_Create", "NewRequest")
                .Read("EditingInline_Read", "NewRequest")
                .Update("EditingInline_Update", "NewRequest")
                .Destroy("EditingInline_Destroy", "NewRequest")

    )

    )

I'm using batch-mode and server-side operations. it looks like you do some special things in the parameterMap function (behind the scenes) when the operation == "read" and filtering is applied.  For example, when a filter is applied to a column, it seems you put the filtering parameters in a special format before sending to the server. Even though I'm using the MVC wrappers, I can still wire-up the parameterMap feature using JavaScript. I did this for ONLY the "destroy" operation (I want to send just the IDs and not the models), but then the "read" operation no longer works when filtering is applied, because my use of parameterMap overwrites what you are doing for "read".

Can I still use the parameterMap feature for only "destroy", and not interfere with what you do with "read" ?  My desire is to send just the IDs and not the models when batch-saving deletes.

I have a chart with many colors. The tooltip should appear as black or white depending on the background color of the chart's bar. The only option I can think of is handle this with the series.name. But nothing works.

This code does accurately put a white or a black piece of text onto the screen as a tooltip:

.Tooltip(tooltip => tooltip
   .Visible(true)
   .Template("# if ((series.name === 'foo') || (series.name === 'bah')) { return '<strong style=\"color: black\">bar</strong>'; } else { return '<strong style=\"color: white\">bar</strong>'; } #")
)

However, once I plug in #= series.name # #= value # instead of bar the function breaks down and it no longer works.

Next, I tried both SharedTemplate and Template as such (one at a time of course):

.Tooltip(tooltip =>
   tooltip.Visible(true).Template("mytemplate")
   tooltip.Visible(true).SharedTemplate("mytemplate")
)

<script id="mytemplate" type="text/x-kendo-template">
   # if ((series.name === 'foo') || (series.name === 'bah')) { #
      <strong style="color: black">bar</strong>
   # } else { #
      <strong style="color: white">bar</strong>
   # } #
</script>

This didn't do anything and instead displayed a tooltip of "mytemplate".

Is this possible to do? If not is there any kind of work around?

hello, I have using the scheduler and when I inspect the control in the javascript console I can see that there is data in the resources.datasource object but for some reason the resources are not displaying in the Timeline. I'm just trying to load resources right now without events. Do I have to have events for the resources to load properly. In the old webforms scheduler you didn't need that. Also, once loaded how do I change them dynamically so that users can manipulate the timeline and look at specific combination of resources. 

 @(Html.Kendo().Scheduler<Avianis.Models.Scheduler.AppointmentViewModel>()
        .Name("scheduler")
        .Date(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day))
        .Views(views =>
        {
            views.TimelineView(timeline => timeline.EventHeight(50));
            views.TimelineWeekView(timeline => timeline.EventHeight(50));
            views.TimelineMonthView(timeline => timeline.EventHeight(50));
        })
        .Resources(resource => resource.Add(m => m.ResourceID)
                     .Title("Aircraft")
                     .Name("Aircraft")
                     .DataTextField("Name")
                     .DataValueField("ID")
                     .DataSource(source => source
                         .Read("GetResources", "Calendar"))
        )
        .DataSource(d => d
                .Model(m =>
                {
                    m.Id(f => f.MeetingID);
                    m.Field(f => f.Title).DefaultValue("No title");
                    m.RecurrenceId(f => f.RecurrenceID);
                    m.Field(f => f.Title).DefaultValue("No title");
                })
                .Read("Aircraft_Read", "Calendar")
        )
    )

Hello, is there an option to remember the state of checkbox'ed items in the TreeView when loading them from the server? Such as when repopulating a complex control the TreeView is a part of?

 Thanks in advance for your speedy reply, Telerik! :)

I’m using MVC Kendo grid and few drop down lists as filters and search button. Grid is bound using Ajax. The filters are defined outside of the grid. When user clicks on the search button i am passing the selected filter values to action method as Model, do the search and return the result. This is working fine when user selects the filter.
However, One of the filter is required filter, so I have [Required] attribute on the model’s property. When user don’t select the required filter, it makes the GetData() action method as expected, I see ModelState is NOT valid as expected.
But here im not sure what should I return when Model is not valid,
Questions:
I have validation summary on the layout page, how do I show model error in ValidationSummary without clearing the grid?When action method returns error, I don’t want to clear the existing result in the Grid. The error should display on top of the page.

Note:  For brevity purpose my sample below showing only one filter. Also I’m not worrying about client side validation.

 Index Page

Hi All

I'm trying to start using my license, but I'm doing something wrong for sure.

I copy to my page of a project that is working, the following script from a new project create thru template Telerik \Web\c# ASP.NET MVC Application, from Index.cshtml. (@(Html.Kendo().PanelBar()..."

But I don't have any change, I move the mouse over the bar, and I saw the new bar, but nothing happen when I click over that position.

 I suppose is missing some bundles, but I don't know what js is missing. 

In the new project everything works well, but not in my.

 Any clue what I must do?
