Hello All,

    I am facing weird designing issue in Grid.
    When i click on first column of grid and then continuously press TAB key, so only grid header row can move but detail records of grid doesn't move.
    Please see attachment details. 


   Thanks in an advance.

Eric,

Hi,

I have implemented NumericTextbox from Kendo-UI-web controls.

Case-1: I just want that when user enters an amount (e.g. 9000) more than allowed max. amount (e.g. 5000), then on lost focus of the input the entered amount (i.e. 9000) is replaced with max. allowed amount (i.e. 5000) by kendo UI. Hence my RangeValidator from Data-annotation doesn't get fired anytime. Our client wants that validation instead of automatic replacement. Please guide us how to achieve this.

Case-2: As the kendo-JS hides the original input and places another to show. This behavior prevents RequiredValidator from data-annotations to get fired at client-side, which is badly required by our client. Please guide us how to achieve this.

Feel free if you find any difficulty to understand above mentioned case studies.

Waiting for quick reply,

Thanks in advance,
PSSPL

I have a grid which I need to refresh after a new record has been added or an existing record is amended.

If I call the setDataSource function the datasource is read and the grid is populated with fresh data.  Unfortunately the column sort will then no longer work.  It does work on first read of the data.

If I destroy the grid and recreate it the sortable columns continue to work, but then all button click handlers run multiple times, eg. second grid create they run 2x, third grid create 3x etc.

What is the correct way to refresh a grid without either breaking the sortable option or getting multiple registrations of the command handlers?

*** UPDATE ***
When the sort breaks I have found that calling setDataSource again fixes it!?

Hello all,

I have updated our application to use Kendo version 2013.1.226 beta that you released. It seems that the new update has broken the Grid BatchEditing feature. In particular, when I click on "Save Changes" button I get the following error:

GET http://localhost:5818/Settings/Editing_Update?models%5B0%5D%5BId%5D=f452ada…e%5D=Sir+de+test+trtrtrrtrtrtrt3434343434&models%5B0%5D%5BDecimalValue%5D= 404 (Not Found)
Both grid and server side setup are made:

Cshtml page

.DataSource(dataSource => dataSource
                .Ajax()
                .Batch(true)
                .ServerOperation(false)
                .Model(model => { model.Id(s => s.Id); model.Field(s => s.Name).Editable(false); })
                .Read("Editing_Read", "Settings", new { type = MF.Model.SettingType.Decimal })
                .Update("Editing_Update", "Settings")
                .Create("Editing_Create", "Settings")
            )

Controller code:

[AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Editing_Update([DataSourceRequest] DataSourceRequest request, [Bind(Prefix ="models")]IEnumerable<Entity> settings)
        {
           //code
        }

        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Editing_Create([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<Entity> products)
        {
           //code
        }

The above code used to work before making the upgrade to Kendo version 2013.1.226 beta.

Can you please check this behavior.


Thank you in advance!

Best regards,
Razvan

Is there any easy way to get the value of the items per page drop down that shows at the bottom of the grid whenever it changes? I'd like to store the changed value in localStorage so the user doesn't have to re-pick the value every time they load the page.

Title says it ^

I want to use grids much like in the web examples: http://demos.kendoui.com/web/grid/index.html  only using Kendo Mobile, what is the right way to achieve this?

From my backend it generate a treeview using a ul/li construction:


However, when I take a look when after init the kendoui treeview, the data-uid's are all randomly recreated.

From there, I took a different approach and used the id attribute for the identifiying the node. However, when a node is drag & dropped the resulting node does not contain the id. Also when custom attributes are used for this purposes the Id of the node is gone.

This leave the treeview completely useless, since postingback to the server is impossible.

So the question is, howto preserve the id's??

I am trying to have a editable grid, minimizing network traffic. The grid is only editied 1/20 page loads.
My data model is like this:
Items: ItemdID, ItemName
ItemSerials: ItemSerialID, ItemSerial, ItemID
Units: UnitID, ItemID, Unit
ItemRental: ItemRentalID, ItemID, ItemSerialID, UnitID, Quantity

There may be multiples serials, and Units for each Item.
The data comes from the backend as a Join: with the fields from all 4 tables.
I would like the grid to Show:
ItemName, SerialNumber, Units, Quantity
But need to save an ItemRental row.

Initially I had the table with an ItemID column, using a template which called a lookup function (getName(itemid)) which displayed the ItemName. In order for this to work, I had to pull the entire Items table into memory, so that the lookup function could use it.

The ItemSerials table is worse, as it has 100,000 serrals, but only a handful are applicable to each item. So in order to show SerialNumber, but have ItemSerialID as my value, I have to pull the whole table into memory too. Yes, for loading the drop-down-list I can use the selected item, and filter the fetched serials based on that, but in order to show SerialNumber, but have ItemSerialID  as my value field using template which alls function like the item name (getSerial(serialid), I need to have all in memory.

I would like to handle this by having all fields as part of my data model, then  only showing four mentioned, and hiding the Id columns. My drop downlist for ItemName woulld be on the item name field would then transport.read in all the items on creation of the first editor (dd list). The DDL would read in the whole Items table, be the editor for the ItemName column, but I would also need it to set the value in the ItemID column:  
I can get the itemID in my 'change' function for the DDL,  like this: e.sender.options.dataSource[e.sender.selectedIndex].ItemID, but then what do I do with it? How do I set the value of the hidden ItemID column?

Then another tricky part is when the Item is selected, I then need to cascade the DDL for the SerialNumber column based on ItemID, not on ItemName....

Is there a better way to solve this problem, and avoid pulling unecessary data into memory? I need to show employer bandwidth test in order to buy.

Thanks,

Hi guys,

1. Is there a way to adjust divs (height specifically) to the size of different mobile platforms using kendo? (perhaps a quicker way than with native js?) or with a css class maybe?

2. Essentially when the app starts up i want the divs to already be in the correct sizes. if I adjust programmatically, when is the best time to call the function? before the call to kendo? right after? the phonegap ready event? 

Hi,

we want to use the grid with virtual scrolling enabled and aggregates in footers and group-footers. Our DataSource is a local Javascript array.

The Problem is:
The aggregate values change while scrolling down the grid. The values reflect the content of the visible selection. 

We want to freeze these aggregate values so they are the same as virtual scrolling would be disabled.

Is this possible?

The only solution that comes to my mind is that we fake server-side aggregates like in this example: http://jsfiddle.net/knWcJ/74/

But is there a simpler way?

Thanks for helping!
