I cannot figure out the best way to make the group headers smaller. Out of the box CSS has sets km-group-title height at 101px but adjusting this invites the weeds... Admittedly, CSS makes my eyes bleed...

All the demos show a much smaller group header... What'd I do wrong?

Thanks

Hi,
I am using a combination of Kendo in Razor with WebApi. I have a dropdown which fetches data from a function which is also used to populate a grid. The issue is that the JSON returned by that function has the list in another JSON object which the DropDownList is not able to understand. So the basic question is how to bind a DropDownList() to a remote data which has a list in another object.
Here is my dropdown

@(Html.Kendo().DropDownListFor(m => m.MyData)
                                .DataTextField("Name")
                                .DataValueField("Id") 
                                .DataSource(source =>
                                {
                                        source.Read(read =>
                                        {
                                            read.Url("../api/sample/").Type(HttpVerbs.Get);
                                        })
                                        .ServerFiltering(true); 
                                })
                                .SelectedIndex(0)
                    )

and the data returned is as following 

{"Data":[
{"Id":4,"Name":"alpha"},
{"Id":5,"Name":"beta"}
],
"Total":6,
"AggregateResults":null,
"Errors":null}

Thanks

We have grid with row set to inline edit. The row has input type of textbox, dropdown and combobox for different columns. There is save button outside the grid, which is enabled if user edited any row content (uses row dirty property to know if row is edited or not). On click save, grid rows get saved.

The expected behavior we want is to open the row in inline-edit mode if user selects the row. However, since on opening the row in inline edit mode, the row dirty is getting set to true even if values of textbox or dropdown or combobox was not changed. As a result, save button is getting enabled.

Is there a way to set dirty to true only if the value is changed in any one of the input?

Hello all,

Scenario:
My web app consists of a Kendo grid bound to Kendo datasource with around 3000 rows. I am pushing updates from the server and updating the datasource, sometimes at the rate of 10 updates/second.

Problem:
Pushing data into the datasource and the resultant grid refresh is taking too much time (pushing data into datasource: 30ms and rendering: 300 ms), much slower than the speed with which updates are being delivered. This makes the UI unresponsive.

Ask:
I have already considered paging, but I want to avoid it. One of the things I want to do is limit grid refreshes to once every 500 ms, as updating the grids any faster will not be of perceptible advantage to the users. So, is there a way to have a datasource-connected grid refresh only at specific times instead of with every update?

If I tweak the refresh() function for Grid class in kendo.web.js, and setTimeout() for 500 ms, then this seems to work, but is that a good way to achieve this "delayed" refresh, or can there be a better and more elegant way of achieving this?
Code follows:

        /**
         * Reloads the data and repaints the grid.
         * @example
         * // get a reference to the grid widget
         * var grid = $("#grid").data("kendoGrid");
         * // refreshes the grid
         * grid.refresh();
         */
        refreshRequestScheduled: false,
        refresh: function(e) {
       
        //if there are requests, return as next refresh will take care of this update
        if (this.refreshRequestScheduled) {
return;
        } else {
        //if there are no more requests, schedule one
        this.refreshRequestScheduled = true;
         var that = this;
        setTimeout(function(e) {

                        ... //original refresh() code

        that.refreshRequestScheduled = false;
        }, 500); //should be triggered in this much time
        }
       }
   });


Thanks,

Hello,
when I use grid frozen columns have a problem, if I set the grid editable is and add one columns for command, the frozen columns will can't work perfect, the line can't aligning if have scrollbar, any way can fixed this problem?

Hi.
You have AutoComplete and NumericTextBox but no simple Input, why?
It'd usefull to have textbox control with same styling as other controls.
Also I'd expect from it to have some vilidation capabilities (max length, mandatory, regexp pattern).

Does Kendo have any functionality available for the following:

1) creating a TreeGrid?  That is the combination of tree functionality and grid.  Not looking for nested grid functionality.  But a tree that contains rows of same information.Similar to: http://www.jeasyui.com/tutorial/tree/treegrid1.php 

2) Tooltips on Tree nodes

3) Three state Tree checkboxes, such that if only part of the child nodes are checked the parent is in a grey 3rd state (partial checked).

Thanks

I have a master/details pair of lists handled by simple listviews.  Clicking the master opens/loads the detail view.  It works, but after a short amount of time going back and forth, the performance gets slower and slower until it is just unusable.  I am using version 2012.3.1315.  It's noticeable in a desktop browser as I test, but gets bad fast with the iPhone.  When I watch task manager when testing with a desktop browser I see memory climb on the Chrome instance I'm running as I go back and forth.  I also notice when I go to the details page it initially displays data from the prior view before refreshing with the current data read into the data source.  When I load the master list, I reload from the data source as the data is very fluid, when I go to the details page, it loads from the data source also.  Could there be a Kendo memory leak? Could this problem be that I currently have all the views/data sources in one Index page?  Is there some Kendo cache I need to turn off? Is there some other way I need to do this to keep performance up?  Thanks.
