So I've got a Kendo Grid initialized like so:
var custData = {
    "columns": [
        { "field": "ID", "title": "ID", "filterable": true, "width": 1 },
        { "field": "Last", "title": "Last", "filterable": true, "width": 1 },
        { "field": "Middle", "title": "Middle", "filterable": true, "width": 12 },
        { "field": "First", "title": "First", "filterable": true, "width": 1 },
        { "field": "Role", "title": "Role", "filterable": true, "width": 1 },
        { "field": "Rank", "title": "Rank", "filterable": true, "width": 1 }
    ],
    "data": [/* Lots of data here, organized like so: */
        { "ID": "00011", "Last": "Picard", "Middle": "", "First": "Jean Luc", "Role": "Commanding Officer", "Rank": "Captain" }
    ]
};
var custDataSource = new kendo.data.DataSource({
    pageSize: 10,
    data: custData["data"]
});
$("#customers").kendoGrid({
    height: 600,
    width: 800,
    columns: custData["columns"],
    dataSource: custDataSource,
    groupable: true,
    scrollable: false,
    sortable: {
        mode: "multiple",
        allowUnsort: true
    },
    pageable: true,
    selectable: "multiple row",
    nagivatable: true,
    toolbar: [
        { name: "create", text: "New" },
        { name: "save", text: "Save" },
        { name: "cancel", text: "Cancel" },
        { name: "destroy", text: "Delete" }
    ],
    editable: {
        update: true,
        destroy: false,
        confirmation: "Are you sure you want to remove this item?"
    }
});

I'm trying to get a grid with a static height and width. It absolutely must not change height and width when I page (which it currently does, due to variably-sized data). The same is true of the data cells. They absolutely must not change size or shape, but they do anyway. I tried setting static width and height, but it seems to be ignoring them to some degree. Beyond that, the column widths are not defining the widths of the columns, but rather the number of pixels to add to the width of the column. Also, it doesn't actually add the specified number of pixels, but some seemingly arbitrary number any given time.

When there's too much data in a cell, it wraps, making the row taller, and thus changing the height of the Grid. That is unacceptable. I require a static height and width, and perhaps it could show the full contained value of the cell on mouseover. I need the values to not wrap or overflow in any way. Is there some way to achieve this?

When paging, the column widths change, throwing off the data alignment. It just looks bad, visually, to be paging through the data, and seeing the column widths changing (and the height of the Grid changing in response to taller rows, too).

Things I need to accomplish, broken out into a list:
  • Static column or cell widths
  • No wrapping of cell content, and no resulting overflow either (white-space: nowrap; overflow: hidden;)
  • Static row or cell heights
  • Static overall Grid height (cannot have scrolling Grids, because may be viewed on mobile platform where scrolling in child containers does not function)
How can I achieve those goals without too much hackery? I'm willing to add a CSS style to address the cell overflow and wrapping issues if necessary, but how about the column/cell widths and row/cell heights? I'm sure that the overall height issue will resolve itself once my rows stop changing height.

Thank you.

Best Regards,

Adrian

Hi All,

I am using remote datasource and binding this by using Odata service.

Example for Odata service: 
_WebServiceAddress + "dataapi/ProductGroupProducts?$orderby=Name&$filter=ProductGroupId eq guid'" + tSelectedId + "'"

and i am trying to filter datasource server side by using datasource filter option. 
Example: 

   $("#DivProductGroupDetailsTable").data("kendoGrid").dataSource.filter({
            logic: "or",
            filters: [
                    { field: "Name", operator: "contains", value: pSearchValue },
                    { field: "DataMatchKey", operator: "contains", value: pSearchValue }
                ]
        });

but i am getting following error:
":"Query parameter '$filter' is specified, but it should be specified exactly once."

Please advise.

Thank you in advance.

regards,
Shankar

Hello

I'm using the ListView to display different items. The item should have a different back color depending on the status of the item.
I was able to change the background-color of a element within the <li> by doing something like this:
<div ${data.Status == 0 ? "style=\"background-color:orange;\"" : (data.Status == 1 ? "style=\"background-color:darkred\"" : "style=\"background-color:darkgreen\"")}></div>
But here I still have the borders of the <li> element. Therefore I would like to set the background-color directly in the <li> element to solve the issue.

Is there a way to set the background-color of the ListItem depending on my Status-Property?

I found a way how to access the css of the parent.
http://stackoverflow.com/questions/258317/jquery-changing-background-of-parent-div 
But somehow I wasn't able to use this in the template.

Thanks in advance!

Kind Regards

Hi,
I am trying to create a ListView with remote json/jsonp databinding for Kendo mobile.
I have seen the databinding demo (http://demos.kendoui.com/mobile/listview/databinding.html), but I can't seem to convert it into a json/jsonp web service.
I also tried with the non-mobile Kendo Web remote binding (http://demos.kendoui.com/web/datasource/remote-data.html) which works great by itself, but not in a Kendo mobile application.

is there a demo similar to the Kendo mobile ListView databinding demo (http://demos.kendoui.com/mobile/listview/databinding.html), but with a json/jsonp web service?

Many thanx

I'm having a problem trying to set the Grid's datasource after the grid has been created.  Here is what I currently have, I've tried a bunch of diffenent vatiations of it, but none have worked.  I can see from the Dev Tools in IE9 that its making the service call.  

$(document).ready(function() {
    
    grid = $("#grid").kendoGrid({
        dataSource: {
               pageSize: 10
           },
           height: 800,
           scrollable: true,
           sortable: true,
           filterable: true,
           pageable: {
               input: true,
               numeric: false
           },
           columns: [
               {
                   field: "UnitId",
                   title: "ID"
               },
               {
                   field: "UnitName",
                   title: "Name",
                   width: 200
               },
               {
                   field: "Location",
                   width: 200
               },
               {
                   field: "Number",
                   title: "Number"
               },
               {
                   field: "Rating"
               },
               {
                   field: "Date",
                   title: "Date"
               }
           ]
       });
 
        setDataSource()
   });
 
 
    
       function setDataSource() {
           //check if the data is in the db
 
           var dataSource = new kendo.data.DataSource({   
               type: "json",
               transport: {
                   read: {
                       url: "http://localhost/DashboardServices/api/Assessments",
                       complete: function(e){ debugger; $("#grid").data("kendoGrid").dataSource.data(e); $("#grid").data("kendoGrid").dataSource.read();}
                   }
               },
               schema: {
                   model: {
                       fields: {
                           UnitId: { type: "string" },
                           UnitName: { type: "string" },
                           Location: { type: "string" },
                           Number: { type: "string" },
                           Rating: { type: "string" },
                           Assessed: { type: "date" }
                       }
                   }
               },
           });

How do I change the contentUrl on a splitter pane...on an event, so the splitter is already defined, I want to change it based on a click event.

So the idea is the splitter pane is collapsed and not resizable on load...click an item, it becomes expanded, changes to resizable and collapsable, and gets a contentURL set based on the value passed in.

(also API lists contentURL as a Bool?)
contentUrl: Boolean(default: true)

When using the following view code, I can't seem to find where I should be setting the type to POST so that it will reach back to the controller methods. 

Right now, if I put the [HttpPost] tag above the method, I get a 404 Not found error when I execute that method.  If I don't have the post tag, then I reach the method but the parameters are empty (Not null, just an empty, but instantiated object).

All of the examples I've seen have [HttpPost] or [AcceptVerbs(HttpVerbs.Post)] above the method.  I've tried both and can't get it to work.

Error:
HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.


Controller:
//Other CRUD omitted for brevity
        [HttpPost]
        public ActionResult CreateProducts([DataSourceRequest]DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<Models.ItemModel> itemsToAdd)
        {
            Models.ShipmentModel shipmentModel = SessionModel;
 
            foreach (Models.ItemModel newItem in itemsToAdd)
            {
 
                if (shipmentModel.ItemModelList.Count > 0)
                {
                    var nextID = (from i in shipmentModel.ItemModelList
                                  select i.ItemID).Max() + 1;
 
                    newItem.ItemID = nextID;
                }
 
                shipmentModel.ItemModelList.Add(newItem);
            }
 
            var items = shipmentModel.ItemModelList;
            DataSourceResult result = items.ToDataSourceResult(request);
            return Json(result, JsonRequestBehavior.AllowGet);

Hi everyone,

I am working on creating cascading combo boxes. I would like to use a data that is being pre-loaded as C# objects, which then will be convert into JSON model and use as a datasource.

I looked at the example code from the cascading combo box demo and realized that it uses Odata points to some web service, which return a large xml-liked file content, which gives me a bit of difficult time understanding how the 1st combo box can be used to determine what get to be displayed on the 2nd combo box.

So if we take cascading combo boxes for country and state as an example. If I were to have the first combo box as a country like this.

        $(".country-combo-box").kendoComboBox({
            dataTextField: "text",
            dataValueField: "value",
            dataSource: [
                { text: "United States of America", value: "US" },
                { text: "Canada", value: "CA" },
                { text: "United Kingdom", value: "UK" },
                { text: "France", value: "FR" }
            ],
            filter: "contains",
            suggest: true,
            index: 0
        });

How would I set up the 2nd combo box, so that if I select the US as a country  and expect the 2nd combo to display on the states that belong to the US although technically the datasource for the 2nd combo box should contains all states for every country?

Would the datasource for the 2nd combo box looks like this? 
 dataSource: [
                { country: "US", text: "New York", value: "NY" },
                { country: "US", text: "Texas", value: "TX" }, 
                { country: "US", text: "Florida", value: "FL" }, 
                { country: "CA", text: "Alberta", value: "AL" }, 
            ], 
If so, how do I set the filter on the 2nd combo box to only select all states for a specific country?

I appreciate your time helping me on this. 

Thank you very much,

Patt
