Hi,

I’am currently testing Kendo UI Grid.  Our product uses Telerik and would like to move towards Kendo.  I have a general question on the Grid control using Row templates.

Let say I use the following row template that I would like to use with a Grid.  The first cell would be bound to the “Field1” of my object.  The second cell is a link that points to a URL bound to “Field2” of my object.

<script id="MyRowTemplate" type="text/x-kendo-tmpl">
<tr>
  <td>${ Field1 }</td>
  <td><a href=”${Field2}”>click me</a></td>
</tr>
</script>

My question is the following.  How would I insert some logic to remove the link if the “Field2” my object set is empty.
In pseudo code I would like to achieve the following.

If myObject.Field2 = “” then
  Do not generate a link
Else
  Show the link with the Url pointing to MyObject.Field2

In other words I’am trying to find a way to have more control on the html generated when binding fields to a grid.  Not sure if using a Row template is the way to go in my case.  

Thanks in advance.

i am trying to disable a drop down list control

here is the code

$("#payment").attr('disabled', 'disabled');

<label for="payments">Payment Type:&nbsp;&nbsp;&nbsp;</label><input id="payment" data-bind="value: payment" name="payment" />

and the code load the datasource

and the function to disable the control by another drop down list choice

the alert's work but the .attr is never firing

Hello and thanks for the awesome controls :)

I have the following test code i am playing with right now,



Now when i add more items to 'data' JSON Array I would like to see changes in the chart,
The following are in my mind right now,
1). using observable collection (kendo.data.ObservableObject) as a data source? such that when the data object changes it reflects in the control (or element) via kendo.bind but i am not sure how to implement this without the need to .refresh() everytime the collection is changed when Add Data button is clicked
2). A way where chart.options.data = data is assigned the control must automatically reflect the new chart ( in other words i am looking for a live charts control like how we do in MVVM, where the object changes and since its bound to the control it just reflects the changes ) but not sure how to implement with this scenario 

could someone please help?

Hello,
 First I want to thank you for those beautiful tools you've made to make developer's life easier.
But It seems that either I can't understand how to bind grind to XML or it's simply not working for the beta version. I look at the demo "xml-grid" but it doesn't list any items at all. 

Thank you in advance.

Hi,

I have a kendo grid. And there is a dropdown. In the grid there is a column having a date field. Now, this date column's data format should be changed according to the value chosen from the dropdown. Suppose, i choose daily or hourly in the dropdown, then i have to display date with time(in the format hh:mm:ss). Suppose i choose weekly, then i have to display date with time(in the format hh).And if i choose monthly or yearly, then only date should be displayed. I am not able to get, how can i change the column definition dynamically. And also, from the server i am getting a date object only as i also have to filter and sort on that column. I am using a template for this column to specify the format. But, depending on various conditions, how can i change the format? Please suggest.

Thanks,
Khushali

I have set 'filterable' and 'serverFiltering' to 'true for a Kendo UI Grid.

In the 'parameterMap' function I am able to get the 'options.filter.logic' and iterate the 'options.filter.filters' array to get the filter values for a single column.

Suppose if the user tries to filter the grid on multiple columns, How can i achieve the above?

The 'options.filter' should be an array so that I could get the 'logic' for each column's filter and so on.

Or Am I misunderstanding this? Is there any other way to get the filter values of multiple columns?

Here is that code snippet.

parameterMap: function (options) 
                        {
                            if (options.filter)
                            {
                                
                                alert(options.filter.logic);
                                alert(options.filter.filters.length);
                                for(var i = 0; i < options.filter.filters.length; i++)
                                {
                                    alert(options.filter.filters[i].field);
                                    alert(options.filter.filters[i].operator);
                                    alert(options.filter.filters[i].value);
                                }
                            }                            
                            
                        }

Hi, I have a grid with inline option, and when I edit a row, a later I click in cancel button, the data in row selected is changed.

The grid is:
                    $("#grid").kendoGrid({
                        dataSource: sharedDataSource,
                        toolbar: [ { "create", text: "Add new Prodduct Group" }],
                        editable: "inline", 
                        change: onChange,
                        selectable: true,
                        height: 400,
                        sortable: true,
                        pageable: true,
                        columns: [
                                { field: "strProdGroupDesc", title: "Product Group", nullable: false, filterable: false },
                                { command: ["edit"], title: " ", width: "110px" }
                        ]
                    })

                    function onChange(arg) {
                        var grid = this;
                        grid.select().each(function() {
                            var dataItem = grid.dataItem($(this));
                            PGDesc = dataItem.strProdGroupDesc;
                            PGId = dataItem.intProdGroupId;
                            alert("Item: " + PGId + "-" + PGDesc);
                        });
                    }

If I using template and editable.
So when you edit the first record it will automatically set to the value of the latter.

I have for example 3 rows. 
        AAA   |  111
        BBB   |  222
        CCC  |  333

If I click first row. 
My grid will be:
        CCC  |  111
        BBB   |  222
        CCC  |  333

My grid code:
    var locationData = {
        columns:[
          {field: "location", title: "Name"},
          {field: "serial",   title: "Serial Number"}
        ],
        filterable: false,
        sortable: true,
        pageable: true,
        scrollable: false,
        selectable: true,
        editable: true,
        height: 200,
        theme: uiTheme,
        rowTemplate: chargePointRowTemplate,
        dataSource: chargePointsDataSource
    };

var chargePointsDataSource = new kendo.data.DataSource({
    data:restData,
    pageSize:5,
    serverPaging:false,
    serverSorting:false,
    schema:{
        data:function (result) {
            return result.points.testpoints
        },
        total:function (result) {
            if (result.points) {
                return result.points.PageSize;
            } else {
                return result.length || 5;
            }
        },
        model: {
            id: "serial",
            fields: {
                location: { editable: true, type: "string", nullable: true },
                serial: { editable: false, type: "string", nullable: false }
            }
        }
    }
});

var chargePointRowTemplate = kendo.template(
    "<tr><td height='20'>#= location #</td><td height='20'>#= serial #</td><td height='20'><div class='status-item_#= status #'></div></td></tr>"
)

Hi there,

I am trying to make the direction of the values for the Y axis to go from 1 to 15, 1 at the top and 15 at the bottom.

1
2
3
4
5

instead of

5
4
3
2
1

If use

valueAxis: {
       reverse:true,
        max:15,
          min:1,
       },

both X and Y axis get reversed. How can I keep the X axis without a change and only change Y?

Thank you
Claudia

I bind my model to a table.
If I update the values ​​with widget, the model is updated.
If I set the value of the widget by value, the model is not updated.
This happens both for the dropdownlist and for both the numerictextbox.

ex.:
var modelDett = $("#nsgridDett").data("kendoGrid").dataSource.getByUid(nsRowDettSelectUid);
kendo.bind($("#tableDetail"), modelDett);

// not update model
var importoKM = 100;
$("#txtImporto").data("kendoNumericTextBox").value(importoKM); //txtImporto -> input of tableDetail
