I have a filter on a datasource which in return updates a grid. The following are the code to filter and its' template handler.

 

The problem with this is that, I can load the categories at first when I'm creating the filters. But when I save and reload the filter from local storage, the category dropdown does not load. Please help me with this. It loads up only on a fresh filter.

Thanks in advance.


@(Html.Kendo().Filter<ReportJob>()
                                .Name("OrganizationFilter0")
                                .ApplyButton(true)
                                .ExpressionPreview(true)
                                .DataSource("OrganizationDataSource")
                                .Fields(f =>
                                {
                                    f.Add(p=>p.OrganizationName).Label("Organization");
                                    f.Add(p=>p.ClarusAccountId).Label("Category").EditorTemplateHandler("CategoryDropdown");
                                    f.Add(p=>p.AsAtDate).Label("As At Date");
                                }))

<script>
function CategoryDropdown(container, options) {
        $('<input data-bind="value: value" name="' + options.field + '"/>')
            .appendTo(container)
            .kendoDropDownList({
                dataTextField: "CategoryId",
                dataValueField: "CategoryId",
                dataSource: @Json.Serialize(ViewData["Catogories"])
            });
    }
</script>

Hello,

I am working with application where I have thousands of images to load on ImageBrowser of Kendo Editor.

ImageBrowser is getting stuck as having too many images to load, Can we have any option to add pagination or lazy loading in ImageBrowser?

So, I can load only 20 images at a time and other based on request.

Please note that I am fetching images from controller method which returns list of FileBrowserEntry as below.

 

 

Thanks,

Trusha

When I try to change the header text to wrap instead of showing ellipsis when it is too long. the sort icon seems to be missing. refer to the image below. what I would like to have is for the sorting icon to be top aligned, beside the word business

Hi,

 

I was researching available control in Kendo to achieve my requirements it seems that multi-select control is what I need. but I am unsure how i do the templating for the control. my markup for the dropdown is 


<select id="users">
<option value="1" data-email="abc@email.com">User 1</option>
<option value="2" data-email="12@email.com">User 2</option>
<option value="3" data-email="adc@email.com">User 3</option>
<option value="4" data-email="anmf@email.com">User 4</option>
</select>

 

what I wanted to achieve is when the user is selecting the option to show User 1 - abc@email.com. then upon selected, the tag to show User 1.

 

I understand that multi-column combo box is able to achieve this but i need to be able to select multiple options. I also prefer to render the control via HTML way instead of using json data source

I'm using the Kendo combobox on a edit form.  I'm loading initial values into the comboboxes on page load by using the "value" and "text" properties.  I have autobind set to false.  If I click the "clear" button it doesn't actually clear out the text value until the second time I click it.  It looks like the first time I click clear it loads the actual data items and then selects the value I have it set to.  The second time I click clear it actually works.  What is the proper way to configure this to load values from the server and preload a specific item when the control initializes?

 


 @(Html.Kendo().ComboBox()
                            .Name("combo" + item.DataField.ID)
                            .Filter("contains")
                            .DataTextField("DataTextField")
                            .DataValueField("DataTextValue")
                            .Placeholder("Select an item...")
                            .AutoBind(false)
                            .ClearButton(true)
                            .DataSource(source =>
                            {
                                
                                source.Custom()
                                    .ServerFiltering(true)
                                    .ServerPaging(true)

                                    .Type("aspnetmvc-ajax") //Set this type if you want to use DataSourceRequest and ToDataSourceResult instances

Hi,

I am trying to use Gantt widget with Drawer located at the right side. 

For some reason, when I position drawer to the right, even with mini mode it is always outside of the screen (horizontal scroll appears) - if i expand drawer, it basically expands it to the right, and remains outside screen, horizontal scroll just expands area.

When drawer is positioned on the left it works normally (pushes gantt for width of drawer).

Behavior can be observed in following Dojo:

https://dojo.telerik.com/EdIQaXeY

Thank you very much

Regards

When I select a filter dropdown value, it gets populated into other filter fields as well.

I have checked my grid configurations, but couldn't figure our what issue is there.

PS: The attachment is an GIF screen recording of the issue.

i have set my th with style="width:240px !important;".

but when the table get render, the actual width of the cell get shrink to 180px. 

kendo grid seems to be trying to shrink the table to fit into the container.

 

my js to render kendo grid is


 $(document).ready(function() {
            $("#kendo-table").kendoGrid({
                sortable: true,
                scrollable: false,
                sort: function(e) {
                    // Prevent the default behavior.
                    e.preventDefault();
                    // Check which column is being sorted. We only need to change the sorting behavior for the first column(the one with the link).
                    let field = e.sort.field;

                    if (field == "link") {
                        // Specify a custom compare function
                        e.sort.compare = function(a, b, desc) {
                            // Extract only the part between <a></a>.
                            let aNoHref = a.link.trim().match(/<a [^>]+>([^<]+)<\/a>/)[1];
                            let bNoHref = b.link.trim().match(/<a [^>]+>([^<]+)<\/a>/)[1]
                            // Compare the two values.
                            return aNoHref.localeCompare(bNoHref);
                        }
                    }
                    // Sort the dataSource manually.
                    this.dataSource.sort(e.sort);
                },
                pageable: {
                    pageSizes: false,
                    messages: {
                        display: "" // set it to an empty string
                    }
                }
            });

            $("#kendo-table").data("kendoGrid").dataSource.pageSize(10);
        });
i have set scrollable to false, is due to not wanting to have the thead inside a table tag while the tbody in another table tag
