We have a scenario where we want to ease into Kendo UI, but have a project that needs to remain on ASP.NET 2.0 Web Forms for a good few months before upgrading (it will still be web forms for a while, before the MVC move).

Basically we need to have a Kendo UI grid initialized with seed data in the form of JSON and allow the user to perform Pop-up Inline Editing (like http://demos.kendoui.com/web/grid/editing-popup.html), but without saving that data back to the server after each edit.  

The user's need to have the ability to see their changes in the data immediately reflected in the grid, but we plan on trying to fit this into a post-back styled architecture by reading the JSON data from the datasource (after it's updated with changes from the user) and copying that to a hidden field which can by POSTed back to a form location (and later on we can change this action to send data to a web service).

Are there any examples of a Kendo UI Grid where the data is edited locally and read out into something (e.g. copied to another JavaScript variable or hidden form field) on item/row update without interacting with a service boundary?

It would greatly ease the decision if something similar or exactly this scenario could be posted/provided on this thread showing that Kendo UI can work with this.

Thanks!

Has anyone had an issue with the datasource calling the same paging over and over? I am trying to come up with a simplified version to test this theory. But here is my code for creating the dataset:


When I run this, it just hits the service over and over for pages 1 to 100. Any ideas?

Hello,

I have a grid bound to a view model array property.

 I am adding new items asynchronously to the array and it works, they are getting displayed in the grid.

However, I see that the grid is adding columns for EVERY property of the item object, even if I specifically set the columns with the fields:

 $(document).ready(function () {
            $("#battleGrid").kendoGrid({
                columns: [
                                      {
                                          title: "Title",
                                          field: "Title"
                                      },
                                      {
                                          title: "Map",
                                          field: "Map"
                                      }]
            });


            $("#battleGrid").kendoGrid({
                selectable: "row"
            });
        });


$(function () {
            viewModel = kendo.observable({

                battles: [],


                addBattle: function (battle) {
                    this.get("battles").push(battle);
                },
            });

            // apply the bindings
            kendo.bind(document.body.children, viewModel);
        });

 <div id="battleGrid" data-role="grid" data-sortable="true" data-bind="source: battles"
                    style="height: 700px">
                </div>

The grid shows 5 columns instead of 2.

This looks very bad, I hope there's a solution.

How can I tell the grid to stop auto generating the columns and create only specific columns?


Thanks!

Hi can anyone let me know how to design a Clustered stack bar chart.
I have already designed stack barchart, but having no idea on clustered stack bar chart.?

Hi Telerik team,

I have a requirement where I would need to let user to select all rows in the grid , by clicking a checkbox , Select/UnSelect All.  Which selects all rows. Click a button, that will take action on the selected rows.
1. Do you have sample reference to do this?

Thanks,
Peruri

In the Kendo Web UI MVVM example (index.html), if you would like to see the kendoComboBox object with value and description bindings instead of the browser's select element, just paste this over the existing script tag in the body of index.html.  Hope this helps someone.

Hi All,

Has anyone experienced the Kendo UI from MVVM pattern? I would like to see the pitfalls in this decision. So that I would be ready for the unexpected.

Thanks for reading

Can someone tell me why this is an invalid template

<script type="text/x-kendo-template" id="recordtemplate">
    <center><h2>#= ActivityName #</h2></center>
@using (Html.BeginForm("recordcompletedactivity","engage"))
{
@(Html.Kendo().DatePicker()
.Name("DateCompleted") 
.Min(new DateTime(1900, 1, 1)) 
.Max(new DateTime(2099, 12, 31))
.Format("MMddyyyy")
.Value(DateTime.Now.ToString()));
@Html.CheckBox("Attest", new { @class = "cb" });
@Html.Encode("Check here to confirm completion this activity");
<br/><br/>
<center>
<input type="submit" class="submit" name="Button" value="Submit" />
</center>
}
</script>


i get the following error
Uncaught Error: Invalid template:' <center><h2>#= ActivityName #</h2></center> <form action="/engage/recordcompletedactivity" method="post"><input class="k-input" id="DateCompleted" name="DateCompleted" type="date" value="07272012" /><script> jQuery(function(){jQuery("#DateCompleted").kendoDatePicker({format:"MMddyyyy",min:new Date(1900,0,1,0,0,0,0),max:new Date(2099,11,31,0,0,0,0)});}); ' Generated code:'var o,e=kendo.htmlEncode;with(data){o='\n <center><h2>'+( ActivityName )+'</h2></center>\t\n<form action="/engage/recordcompletedactivity" method="post"><input class="k-input" id="DateCompleted" name="DateCompleted" type="date" value="07272012" /><script>\n\tjQuery(function(){jQuery("';DateCompleted").kendoDatePicker({format:"MMddyyyy",min:new Date(1900,0,1,0,0,0,0),max:new Date(2099,11,31,0,0,0,0)});}); ;o+=;}return o;' 

I'm displaying records from a DB in a kendo grid, and one DB field is a datetime.

I'm using the following to display the value: kendo.toString(datetime,"dd MMMM yyyy, h:MM:ss")

This works, but the time it displays is incorrect. For instance if the value in the DB is "2012-07-27 15:28:11.383" the value displayed will be "27 July 2012, 3:07:12", which is off by about 21 minutes.

What's up with that?

Hi,

I have an object in my Model that must be bounded to two ViewModels. This object is loaded with ajax from the server.

This object must be  bounded to two regions of my screen that have, each one, different ViewModels. I would like that when the response arrives from my Ajax service the two widgets, bounded to my ViewModels, be updated.

How can I do this.

Thanks
