Hello.
We are trying to implement pagination (with virtual scrolling instead of actual pages) for every group of Grid widget. So, we have Grid with serverPaging, serverGrouping and virtual scrolling. As far as I understand, Kendo Grid doesn't support paging if it's grouped. So, the idea is to return from server empty grouped results (with empty items for every group), collapse all groups by default and then after user opens a group - send separate request and populate just this particular group.
Could you please help us with implementation showing an example of something similar or tell any better way to reach the goal?
Just to make it clear - currently our grouped (aggregated) data can have millions of rows in every group.
Thank you.

We've been using different themes for our application, and are having some trouble with the "Flat" theme.
When adding icons to widget contents (ex. Kendo Window), the icons don't show up. Reason seems simple: both icons and widget background are white. :)
This can be seen easily in the icons demo page (switch to Flat theme):
http://demos.telerik.com/kendo-ui/styling/icons
Any plans to make Flat theme work the same way as other themes, or any workarounds for this?

Hi,
I have searched all the document & demo, but no records about how to send costom para(argument) to event handler.
1. In jQuery, we could do this:
jQuery("#test").bind("keyup",{sendpara: thepara},function(event) {alert(event.data.sendpara);});var editor = jQuery("#test").data("kendoEditor"); editor.bind("keyup",{sendpara: thepara},function(event) {alert(event.data.sendpara);});2. I found this:
http://www.kendoui.com/forums/kendo-ui-framework/mvvm/passing-parameters-through-html-bindings-mvvm.aspx
it says we could:
var viewModel = kendo.observable({ Id: "users/1", Points: 10, ReducePoints: function(id) { console.log(this.get("Id")); }}); jQuery("#test").kendoEditor({ sendpara:"123" });var editor = jQuery("#test").data("kendoEditor"); editor.bind("change",function(event) { alert("b:"+ this.get("sendpara") ); });3. At last, I found this:
http://www.kendoui.com/forums/kendo-ui-web/numeric-textbox/get-element-id-from-change-event-handler.aspx
So I changed my code to:
jQuery("#test").kendoEditor(); var editor = jQuery("#test").data("kendoEditor"); editor.bind("change",function(event) { alert("b:"+this.element.attr("sendpara") ); });This is really not very good.
So the general question is this: where can I find documentation on the properties and methods of the event argument parameter?
Or kendoUI not really support to send para to an event handler?
If so, that's really a bad news, because it's very ordinary need to send some paras in to event handler, and to handle some ajax call or function to send this paras to the server, and so on.
yours,
Ivan

Because
the rendering indication of the screen takes time and wants to suppress half of
the processing time to degree, I investigate a solution.

This is my master grid
$(document).ready(function() { $("#grid").kendoGrid({ height: 800, sortable: true, pageable: true, selectable: "row", filterable: { mode: "row" }, editable: { //disables the deletion functionality update: false, destroy: false }, scrollable: true, groupable: true, pageable: { pageSizes: [10, 25, 50, 100], refresh: true, buttonCount: 5
This is the subgrid, when I click the save button, it never make to the POST to the php script. Is there a bug I have to make a event for make the POST?
01.function detailInit(e) {
02. // get a reference to the current row being initialized
03. var detailRow = e.detailRow;
04.
05. detailRow.find(".subgrid").kendoGrid({
06. dataSource: {
07. transport: {
08. read: "./data/getDetails.php",
09. update: {
10. url: "./data/getDetails.php",
11. type: "POST"
12. }
13. },
14. schema: {
15. data: "data"
16. },
17. serverFiltering: true,
18. filter: {field: "candidate_id", operator: "eq", value: e.data.candidate_id}
19. },
20. sortable: true,
21. pageable: true,
22. selectable: "row",
23. height:300,
24. pageable: {
25. pageSizes: 5,
26. refresh: true,
27. buttonCount: 5
28. },
29.
30. //rowTemplate: kendo.template($("#rowTemplate").html()),
31. columns: [
32.
33. {title: "Task", field: "ARS",width: "100px",filterable: {
34. cell: {
35. showOperators: false
36. }
37. }},
38. {title: "Score", field: "Value",width: "250px"},
39. { showOperators: false}
40. ],
41. detailInit: detailInit,
42. editable: true,
43. navigable: true,
44. toolbar: [ "save", "cancel" ]
45.
46. });
47. }
48.
49. });
Please advice, I had been working on it for a while, still havent figure out the details. To make this work.
Do I have to define the schema to fix the problem? But even without it , everything looks great

Hi,
Is it possible to use different editable modes for different actions? For example; when creating a new record, I want to use the "popup" window option, but when editing, I'd like to be able to do so "inline".
Thanks,
Grant

Following is my grid.
$("#grid").kendoGrid({
selectable: "single cell",
allowCopy: true,
change: function(e) {
var selected = this.select();
var row = this.select().closest("tr");
selectedRow = this.dataItem(row);
deselectSelection();
},
excel: {
fileName: "Report.xlsx",
allPages:true,
filterable: true
},
dataSource: {
schema: {
model: {
fields: columnSchemaModel
}
},
transport: {
read: function (e) {
e.success(reportList);
}
},
pageSize: 500,
aggregate: aggregateList,
change: function(e) {
var dataSource = this;
if (typeof dataSource.filter() != "undefined") {
app.fltrButton.enabled = true;
}
}
....
I am trying to capture datasource change when filter by column. Change function fires as expected. ' app.fltrButton.enabled = true; ' is a variable of button class. If it set to true, css class of button changes. However it doesn't get effect unless I click on another parallel button. So it's the html that doesn't get update, not the value. Please provide a suggestion.

How can I dynamically insert new item after/before specific item or at the beginning. The only method is add.
Menu, ContextMenu, TabStrip, PanelBar, Splitter have append, insertAfter and insertBefore methods.

I need to build a drawing tool which can save to a stream (possibly JSON) and load form the same stream either to display or make changes.
This scenario does not seem to be supported by the drawing API but since the Surface has a draw method, I am assuming it has an internal representation of drawing objects which can be saved and reloaded.
What would be the best approach to achieve this.
Would you have a basic dojo/fiddle available?

We are trying to make our applications compliant with the Web Content Accessibility Guidelines (WCAG) (https://www.w3.org/TR/WCAG20/). One of the requirements is that buttons have text associated with them.
When I created a grid (markup provided below), it fails WCAG compliance because the filter buttons in the column headers do not have text associated with them. I found a way to add the text into the span using javascript but it seems like there should be a better way.
Then I noticed that your demo grid (http://demos.telerik.com/kendo-ui/grid/filter-menu-customization) has the text property set. If I inspect the markup for one of the filter buttons in your demo, I see this:
<a class="k-grid-filter" href="#" tabindex="-1"><span class="k-icon k-filter">Filter</span></a>
So my question is...how did the text property of the span get the value "Filter"? And how can I accomplish that in my grid defined as follows:
@(Html.Kendo().Grid<Staff.Models.Employee>()
.Name("grdEmployees")
.Columns(columns =>
{
columns.Bound(p => p.FirstName).Width("9%").Title("First Name").Filterable(f => f.Extra(false).Operators(o => o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains")));
columns.Bound(p => p.LastName).Width("9%").Title("Last Name").Filterable(f => f.Extra(false).Operators(o => o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains")));
columns.Bound(p => p.OfficeDesc).Width("25%").Title("Office").MinScreenWidth(900).Filterable(f => f.Extra(false).Operators(o => o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains")));
columns.Bound(p => p.WorkUnitDesc).Width("15%").Title("Work Unit").Filterable(f => f.Extra(false).Operators(o=> o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains"))).MinScreenWidth(900);
columns.Bound(p => p.EMail).Width("18%").Title("Email").Filterable(f => f.Extra(false).Operators(o=> o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains")));
columns.Bound(p => p.Phone).Width("8%").Title("Phone").Filterable(f => f.Extra(false).Operators(o => o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains")));
columns.Bound(p => p.Title).Width("16%").Title("Title").Filterable(f => f.Extra(false).Operators(o=> o.ForString(s => s.Clear().Contains("Contains").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to").StartsWith("Starts with").EndsWith("Ends with"))).Cell(cell => cell.Operator("Contains"))).MinScreenWidth(900);
})
.ClientRowTemplate(
"<tr >" +
"<td >#: FirstName# </td>" +
"<td >#: LastName# </td>" +
"<td >#: OfficeDesc #</td>" +
"<td >#: WorkUnitDesc #</td>" +
"<td ><a href='mailto:#: EMail #' title='Send Email' alt='Send Email' >#: EMail #</a></td>" +

@"<tr class=""alt-row"" >" +

"<td >#: LastName# </td>" +
"<td >#: OfficeDesc #</td>" +
"<td >#: WorkUnitDesc #</td>" +
"<td ><a href='mailto:#: EMail #'>#: EMail #</a></td>" +
"<td style='white-space:nowrap;' >#: Phone #</td>" +
"<td >#: Title #</td>" +
"</tr>"
)
.Pageable()
.Sortable()
.Filterable()
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Read(read => read.Action("Staff_Read", "Staff"))
.Filter(f => f.AddRange(ViewBag.filters))
)
)
Thanks,
Ray
