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






 

I believe I may have found a bug in the class assignment of spans when using a Grid with inline editing. When adding a new record with a field that is designated as a number, I get a textbox with arrow on the right to adjust the value up or down. Both arrows that are appearing are up arrows. I looked at the rendered code and saw the following:


notice the "k-i-arrow-n" and "k-i-arrow-s" classes. These are not located in the CSS file. I changed the classes to "k-arrow-up" and "k-arrow-down" and the arrows rendered properly.

I've added local style definitions on my page to correct this, but thought I would let you know to update the code. Thanks.

Is there a way to have a column in a grid lets say the first column to move along with the scroll bar and always be the first column like in excel. Any help regarding this is much appreciated.

Problem: Grid contents after refresh
Context: Grid backed by a JSON remote service -- Python Django + Tastypie

Steps to Reproduce:
1. Setup your data feed such that based on the pageSize that the last page only contains one item. 
2. Initialize your kendo grid 
3. Delete the item on the last page. 
4. Refresh the Kendo Grid
[code]

function refreshKendoGrid(gridId) {

var grid = $(gridId).data("kendoGrid");

//reload grid's datasource

grid.dataSource.read(); 

// refreshes the grid

grid.refresh();

}
[code]

5. Grid shows no entries within the k-grid though the page number is set to correct page (page 1, prior to item deletion there were 2 pages)

 

I'm using the function Json to serialize a Linq query, and on the client side I'm got this result for dates:  "/Date(1343800800000)/" 

How can I tell the grid this is a date?, and more important, how can I fllter it?

I know I can use templates to display the date, but I can't use filters

I tried your demo on this web where it show how date picker can do globalization. When I changed culture to Thai, the year incorrectly showed Buddhist year (2555). Is there a way to fix this?

If we have a table, and the rows (tr) are each are bound to a function off of "visible"...how do you handle that in the function itself

The TR looks like this

<tr data-mf="3" data-bind="visible: isSelectedMF">

...so in that function is there any way to get that "3" from the data-mf element?

Hi All,

I have a datasource that is defined and under a specific circumstance i need to run a function after a read() is completed.

Is something like this possible:

dsCommodities.read(function () {
                //do stuff
            });


I have the ds defined normally but need to dynamically execute a function for one particular read scenario. thanks!

Please help me. I encountered a very strange behavior of the kendoDateTimePicker widget.

When i'm using kendoDateTimePicker widget as editor in kendoGrid, and click on clock icon, this widget show me string "01.01.1900" before time part in drop-down list (see attached picture).

For example:
   ...
"01.01.1900 4:30"  instead of  "4:30"
"01.01.1900 5:00"                    "5:00"

  ...

My source code is:
