Hi All,

Struggling with a very peculiar problem.

I have a Kendo grid with kendo dropdownlist in some of the columns. The dropdown is populated based on values from in the database.

Problem:

On Edit in grid, the dropdown is not preserving previous saved value. 

Please can you help me in finding  the solution for the problem.

VIEW Code:

 @(Html.Kendo().Grid<ViaPath.LookUpDataManagement.MvcApp.Models.MasterDataMappingModel>(Model)
    .Name("gridTable")    
    .HtmlAttributes(new { style = "font-family: verdana,arial,sans-serif; font-size: 11px;color: #333333;border-color: #999999;" })
    .Columns(columns =>
    {
        columns.Bound(p => p.ClientAppName).ClientTemplate("# try {# #=ClientAppName# #} catch (e) {}#").EditorTemplateName("ClientComboBoxLookup").Width(120).Filterable(ft => ft.UI("ClientApplicationsFilter"));
      
        columns.Bound(p => p.SupplierAppName).ClientTemplate("# try {# #=SupplierAppName# #} catch (e) {}#").EditorTemplateName("SupplierComboBoxLookup").Width(120).Filterable(ft => ft.UI("SupplierApplicationsFilter"));
      
        columns.Bound(p => p.ListName).ClientTemplate("# try {# #=ListName# #} catch (e) {}#").EditorTemplateName("MasterDataListsComboBoxLookup").Width(150).Filterable(ft => ft.UI("ListsFilter"));
        columns.Bound(p => p.ClientValueName).Width(120).Title("Client Value");
        columns.Bound(p => p.ClientValueDescription).Width(200);
        columns.Bound(p => p.ClientCodingSystem).Width(150);

        columns.Command(command =>  {
                command.Edit();
                command.Destroy();
            }).Width(200);

                    .ServerOperation(true)

@(Html.Kendo().DropDownListFor(m => m)
        .Name("ClientAppName")

        .DataTextField("ApplicationName")
        .BindTo((System.Collections.IEnumerable)ViewData["Applications"])

Hi

 version 2015.1.515

 I try use dropdownlist with virtual in kendo grid, edit mode - InCellEdit. Works fine for select new value, but if i open cell for edit, dropdown show default value (option label). Autobind is set to false.

With version 2015.1.515 and Autobind = false, works with litle hack. (on grid Edit event after 500ms i call dropdown.datasource.read()).

But with version 2015.1.515 not work anymore, still reset value to default. I found another hack how this work, but i'm not happy with it. On edit event after some ms set value to dropdown from grid model.

 Is another way to use dropdownlist with virtual in grid with incell edit? Thanks

 Editor template for grid

Hello,

 I have a context menu on a appointment with a right click, together with a changed event on a selectable scheduler to track the selected item, which I need in the contextmenu. The problem is when I have a context menu open and I do a right-click on another appointment the change event for the scheduler doesn't fire. This leads to actions on the wrong event because the selected item is not updated.

How can I solve this?

events.Change("onSelectionChanged");

 function onSelectionChanged(e) {
   currentEvent = e.events[0];

Hi guys,

So, I'm developing a timesheets functionality for our product.

For the week view I have a grid and a model bound to it with some ids for project/client/item/etc. and each of the seven days of the week as decimals.

This works great when entering the time as decimal values, eg: 2.5 or 1.15. I use a clientTemplate to format it and display it as 02:30 or 1:09.

So far so good. Now comes the requirement that we want to be able to also input time as 2:30 or 1:09. The problem is the input box does not allow me to input the ":" sign. My workaround was to use string instead of decimal in the model for days. Got that to work nicely but now the sum aggreggates don't work anymore.

Since I know we cannot have custom aggreggates my question is: how can I sort this issue? I would prefer to have the model as decimal and a way to also input time as 00:00 since I can split them apart and make a decimal out of it to fit the model.

Thank you for your time.

Kind regards,

Mircea D.

I use this to validate required fields on post

and it works fine if field is required but if its a mask with wrong entry it doesnt work.

Do you have some sample where the mask is checked on post?

I'm using Kendo().DropDownList() with OptionLabel configured.

When trying to get selected item Text / Value, I'm getting incorrect values.

for example if I choose the first drop down option I'm getting the value of the option label.

if I choose the second option I'm getting the values of the first option.

@(Html.Kendo().DropDownList()
            .Name("SelectedSubjectId")
            .DataTextField("Text")
            .DataValueField("Value")
            .Filter("contains")
            .OptionLabel("Select Subject")
            .BindTo(Model.MailSubjectList)
            .Events(events =>
                    {
                        events.Select("onSelect");
                    })
        )

Javascript:

onSelect = function (e) {
    var dataItem = this.dataItem(e.item.index());

     // or even

    var selectedValue = this.value()

    var selectedText = this.text()

};

How can I get the correct selected value (Text / Value) ?

Thank you.

To avoid sending thousands of records back to my control, I have set the minlength equal to 2. This has been working without issue until I upgraded Kendo UI from a 2014 version to the latest 2015 version. The filtering and control works but the first time you type to start filtering and you reach your minlength, the dropdown appears(as expected with the filtered data) but the text that was typed in the combobox gets erased. When you continue typing, no additional filtering happens until you reach the minlength, at which point the control behaves correctly. The only way for the problem to reoccur in that control again is to reload the page.

I have several pages that use this control. All of them now have this behavior but worked fine before the upgrade.

Thanks,

Let' s say, there a mvc grid with a dropdown list inside it. The grid has three mode; view edit and add modes, in other words users are able to  view, edit, and add records.

The data source of this dropdown list changes dynamically depending on the modes; for example,

if in view mode, the ddl lists item1, item2, item3 item4, and item5,

if in Add mode, the ddl lists item2, item3.

if in Edit mode, the ddl lists item2, item5,

That means the ddl source from different linq queries depending on grid modes.

Is it possible to achieve it? Thanks
